The technical field to which the invention relates.

The present invention relates to a method of placement of the channels and the base station device in the radio communication system on multiple carriers.

The level of technology

In recent years, in radio communication and, in particular, mobile communication has become used to transfer information of various kinds (except speech), for example, images and data. Given the prediction that the requirements for higher data transfer rates will rise, there is a need in the technology of radio, providing high transmission efficiency based on the more efficient use of limited frequency resources to perform high-speed transmission.

One of the technologies of radio, able to satisfy these requirements, is the multiplexing orthogonal frequency division multiplexing (OFDM). OFDM is a transmission technology on several carriers, which runs parallel data transmission using multiple subcarriers, and it is known that this technology is distinguished by such features as high frequency efficiency and reduced intersymbol interference in multipath propagation, and also gives good results from the viewpoint of improving transfer efficiency.

When the transmission with frequency planning unit of the base station radio (which is hereinafter simply called base station) adaptive allocates subcarriers to mobile stations on the basis of the obtained data about the quality of each frequency band at each mobile station that allows you to get the maximum benefit from multiuser diversity and implement highly effective communication. Such transfer with frequency planning mainly suitable for data transmission in those cases, when a mobile station moves from a low speed or high speed data transmission. On the other hand, for transmission with frequency planning required feedback in the form of the received quality information for each mobile station, and therefore, such transfer is not suitable for data transmission when the mobile station moves at a high speed. Transmission with frequency planning is usually performed at the time ticks PE is Adachi, called subquadrate, for a single resource block (RB), in which several neighboring subcarriers are gathered together in one unit. Channel to perform this type of transfer with frequency planning is called localized channel (hereinafter denoted as Lch).

In contrast, when the transmission frequency diversity data for each mobile station are allocated by distributing among subcarriers of one common band, which allows to obtain a significant effect of frequency diversity. In addition, for transmission with frequency diversity is not required to obtain quality information from the mobile station, and therefore, this transfer method is effective in cases when it is difficult to use the above-described transmission with frequency planning. On the other hand, the transmission frequency diversity is performed regardless of the received quality data to the mobile stations, and therefore does not provide the effect of multiuser diversity, which is obtained using the transmission frequency planning. Channel to perform this type of transfer with frequency diversity, called distributed channel (hereinafter referred to as Dch).

Possible concurrent transmission with frequency planning in the channel Lch and the transmission frequency diversity in ka the ale Dch. That is, the block RB used for channel Lch and block RB used for channel Dch, can be multiplexed in the frequency domain on multiple subcarriers of one OFDM symbol. At the same time pre-set mapping between each block RB and channel Lch and the mapping between each block RB and channel Dch, and the decision about which block RB be used as a channel Lch or channel Dch is taken for each subcode.

It was also studied the proposal associated with the additional separation of the RB used for channel Dch on multiple subunits and the formation of a single channel Dch by combining different subunits RB if the display of multiple channels Dch with consecutive channel numbers on many blocks RB, following each other in the frequency domain (see, for example, non-patent document 1).

Non-patent document 1: R1-072431 “Comparison between RB-level and Sub-carrier-level Distributed Transmission for Shared Data Channel in E-UTRA Downlink” 3GPP TSG RAN WG1 LTE Meeting, Kobe, Japan, 7-11 May, 2007

The invention

The problem addressed by the invention

Here, when the base station allocates to the one mobile station multiple channels Dch, we can assume that many of these channels allocated sequential numbers. Thanks to this mobile station can determine its allocated channel Dch, having only the first channel number and last channel number of the number of consecutive channel numbers, communicated to the base station of the mobile station. The result can be a reduced amount of control information for the message on the allocation of channels Dch.

However, if the selection of one mobile station multiple channels Dch may be that when there are many blocks RB, which posted the Dch channels with consecutive channel numbers are used, only those sub-blocks in units of RB, which highlighted these channels Dch. Therefore, may reduce the efficient use of communication resources, because the other subunits not included in the number of subunits will not be used.

For example, if 12 blocks RB #1 to #12, consecutive in the frequency domain, each divided into two subunits, and the Dch channels #1 to #12 with consecutive channel numbers are displayed on the sub-blocks #1 to #12, the Dch channels #1 to #6 are displayed respectively on one subunit blocks RB #1 to #6, and channels Dch from #7 to #12 are displayed according to another subunit of the blocks RB #1 to #6. Similarly, the Dch channels #1 to #6 are displayed respectively on one subunit of the blocks RB #7 through #12, and the Dch channels from #7 to #12 are displayed according to another subunit of the blocks RB #7 through #12. Thanks to this channel Dch #1 is formed by the subblock of RB #1 and the subblock of RB #7. The above explanation applies to the Dch channels from #2 to #12.

The aim of the present invention is the provision of distribution channels and the base station, which can prevent reduction in the efficiency of use of the channel resource due to perform transmission with frequency diversity, while simultaneously performing transmission with frequency scheduling transmission and frequency diversity in the system due to multiple carriers.

The solution

The distribution channels of the present invention provides plenty of subcarriers forming the signal on multiple subcarriers to be split into multiple resource blocks, and a variety of distributed channels with consecutive channel numbers to be placed in the same resource block.

The positive effect of inventions

According to the present invention can prevent a decrease in the efficiency of use of the channel resource due to perform transmission with frequency diversity, while simultaneously performing transmission with frequency planning and transmission with frequency diversity in the system due to multiple carriers.

The best way of carrying out the invention

Next, with reference to the accompanying drawings describes variants of the present invention.

(Option 1)

The configuration of base station 100 according to this variant shown in Fig. 1. The base station 100 shared set of subcarriers forming the OFDM symbol, which is a multi-carrier signal, according to the multitude of blocks RB and uses the channel Dch and channel Lch for each block RB in a specified set of blocks RB. Also in the same subcode for one mobile station to allocate or channel Dch or the channel Lch.

The base station 100 is equipped with n sections 101-1 to 101-n coding and modulation, each of which contain the encoding section 11 and section 12 modulation for data Dch, n sections 102-1 through 102-n coding and modulation, each of which contains the encoding section 21 and section 22 of the modulation data for Lch, and n sections 115-1 to 115-n demodulation and decoding, each of which contains a demodulation section 31 and section 32 is kodirovanija, where n is the number of mobile stations (MS)with which the base station 100 can communicate.

In the sections 101-1 to 101-n encoding and modulation section 11 performs encoding processing turbomotive or similar encoding data channel Dch #1 to #n to the mobile stations #1 to #n, and section 12 performs modulation processing modulation Dch data after encoding to generate symbol data channel Dch.

In the sections 102-1 through 102-n encoding and modulation section 21 performs encoding processing turbomotive or similar encoding data channels Lch #1 to #n to the mobile stations #1 to #n, and section 22 performs modulation processing modulation Lch data after encoding to generate symbol data channels Lch. The encoding speed and scheme of modulation correspond to the information about the modulation scheme and coding (MCS)of section 116 of adaptive management.

The allocation section 103 allocates Dch data symbol and the Lch data symbols to subcarriers forming the OFDM symbol in accordance with a control signal from the section 116 of adaptive control and performs the output section 104 multiplexing. At the same time, the allocation section 103 allocates together Dch data symbol and the data symbol Lch for each block RB. Also, when using multiple channels Dch to Dch data symbol of one mobile station is ncii, section 103 allocation uses the Dch channels with consecutive channel numbers. That is, the allocation section 103 allocates many different channels Dch with consecutive channel numbers for Dch data symbol of one mobile station. In each block RB in advance ensures mutual display placements channels Dch and Lch. That is, the allocation section 103 in advance supports the scheme, which forms a communication between the channels Dch, Lch and blocks RB, and allocates Dch data symbol and the data symbol Lch each block RB in accordance with the specified layout. Placements Dch under this option are described in detail below. Section 103 selection also displays information on the allocation of symbols Dch data (information indicating which symbol data Dch mobile station which block RB was selected), and the information on the allocation of symbols Lch data (information indicating which symbol data Lch mobile station which block RB was selected) in section 105 creating control information. For example, information on the allocation of Dch data symbols included only the first channel number and last channel number of the number of consecutive channel numbers.

Section 105 creating control information generates control information containing information about the allocation of data characters Dch information about Sidelnikov Lch data and information about the scheme (MCS) entered from section 116 of adaptive management, and outputs this control information in the section 106 encoding.

Section 106 performs encoding processing of encoding based on the control information, and section 107 performs modulation processing of the modulation on the basis of the control information after encoding and outputs the control information in section 104 multiplexing.

Section 104 multiplexing multiplexes control information with data characters entered from section 103 selection, and outputs the resulting signals in section 108 of the inverse fast Fourier transform (IFFT). Multiplexing of control information is performed, for example, on posovetoval basis. In this embodiment, for multiplexing control information can be used or multiplexing in the time domain, or multiplexing in the frequency domain.

The IFFT section 108 performs IFFT processing on the set of subcarriers that comprise multiple blocks RB for which the dedicated control information and character data, to generate an OFDM symbol, which is the signal on multiple carriers.

Section 109 adding a cyclic prefix (CP) adds the signal that is identical to the tail part of the OFDM symbol to the beginning of the OFDM symbol as prefix CF.

Section 110 of the radio performs transmission processing, such is the AK-analog conversion, amplification and conversion with increasing frequency, OFDM symbol after adding CF and sends it to each mobile station through the antenna 111.

Meanwhile, section 112 of the radio receives the n OFDM symbols transmitted at the same time the maximum of n mobile stations via an antenna 111, and performs reception processing such as conversion downconverter and analog-to-digital conversion of these OFDM symbols.

Section 113 remove the CF removes the prefix CF of the OFDM symbol after treatment admission.

Section 114 of the fast Fourier transform (FFT) performs FFT processing of the OFDM symbol after removal of the CF to receive signals for each of the mobile stations are multiplexed in the frequency domain. Here, the mobile station transmit signals using different from each other subcarriers or different from each other blocks RB and the signal for each mobile station includes information as to each block RB transmitted from the corresponding mobile station. Each mobile station can perform the measurement for quality assessment based on a received signal-to - noise ratio (SNR), received signal-to - interference" (SIR), received signal-to - interference plus noise ratio (SINR), received signal carrier - interference plus noise ratio (CINR), received power, interference power, the frequency of appearance is s bit error rate (ber bandwidth scheme (MCS) to ensure a predefined bit error rate, or other information as may be submitted as an indicator of channel quality (CQI), information about the state of the channel (CSI) or the like

In the sections 115-1 to 115-n demodulation and decoding each section 31 performs demodulation processing for demodulation signal after conversion, FFT, and each section 32 performs decoding processing to decode the signal after demodulation. Thus, the generated received data. The accepted information about the quality of received data is introduced in section 116 of adaptive management.

Section 116 of adaptive management performs adaptive control of data transfer for data Lch based on the received quality information for each block RB, which transmits each mobile station. That is, based on the received quality information for each block in the RB section 116 adaptive management selects scheme (MCS), able to satisfy the requirement for the frequency of occurrence of errors for sections 102-1 through 102-n coding and modulation, and outputs information about the scheme (MCS). Also section 116 adaptive management performs frequency planning, which determines to section 103 of the allocation, which block RB select data Lch #1 to #n, using the method Maxim is a high relationship SIR, the method of proportional fairness or similar scheduling algorithm. In addition, section 116 adaptive control displays information about the scheme (MCS) for each block RB in section 105 creating control information.

The configuration of the mobile station 200 according to the variant shown in Fig. 2. Mobile station 200 receives from the base station 100 (Fig. 1) the multi-carrier signal representing the OFDM symbol that contains a number of subcarriers is divided into many blocks RB. Many blocks RB channels Dch and Lch are used to block (RB) basis. Also in the same subcode mobile station 200 is allocated or channel Dch or the channel Lch.

In the mobile station 200 section 202 of the radio receives the OFDM symbol transmitted from base station 100 via antenna 201, and performs reception processing such as conversion with increasing frequency and analog-to-digital conversion of the OFDM symbol.

Section 203 remove the prefix CF removes the prefix CF of the OFDM symbol after treatment admission.

Section 204 transform FFT performs FFT processing of the OFDM symbol after the removal of the prefix CF to obtain the received signal, which is multiplexed control information and character data.

Section 205 demuxing further demultiplexes the received signal after FFT conversion on the control signal the al and character data. Then section 205 of the demux outputs the control signal in a section 206 demodulation and decoding, and outputs the symbol data in section 207 of the inverse mapping.

Section 206 demodulation and decoding section 41 performs demodulation processing for demodulation control signal, and section 42 performs decoding processing to decode the signal after demodulation. Here, the control information includes information on the allocation of symbols Dch data, information on the allocation of symbols Lch data and information about the scheme (MCS). Then section 206 demodulation and decoding outputs information on the allocation of symbols Dch data and information on the allocation of Lch data symbols within the control information in section 207 of the inverse mapping.

Based on information on the allocation received from section 206 demodulation and decoding section 207 reverse display retrieves data symbol allocated to this station from the set of blocks RB, which was selected symbol data received from section 205 demuxing. In the same way as in the base station 100 (Fig. 1), for each block RB in advance are displayed placements for Dch channels and Lch. That is, section 207 reverse display in advance maintains the same layout as the allocation section 103 in the base station 100, and extracts from the centre of the VA blocks RB Dch data symbol and the data symbol Lch in accordance with this layout. As described above, when using section 103 allocation in the base station 100 (Fig. 1) multiple channels Dch to Dch data symbol of one mobile station, use the Dch channels with consecutive channel numbers. Information on the allocation contained in the control information from the base station 100, indicate only the first channel number and last channel number of the number of consecutive channel numbers. Thus, section 207 reverse display identifies the channel Dch used in the Dch data symbol allocated to this station, based on the first channel number and last channel numbers listed in the above-mentioned information on the allocation. Then section 207 reverse display retrieves the block RB displayed in the channel number identified channel Dch, and outputs the data symbols allocated to this extracted block RB, section 208 demodulation and decoding.

Section 208 demodulation and decoding section 51 performs demodulation processing for demodulation of data symbols received from section 207 reverse display, and section 52 performs decoding processing to decode the signal after demodulation. In this way receive the received data.

Meanwhile, in section 209 encoding and modulation section 61 performs encoding processing for turbaco the financing or similar coding data transmission, and section 62 performs modulation processing for modulation data transmission, the last encoding, to generate data symbols. Here, the mobile station 200 transmits the data transmission using different subcarriers or different blocks RB from other mobile stations, and the transfer contains the received information about the quality for each block RB.

Section 210 performs IFFT IFFT processing on the set of subcarriers forming many blocks RB for which the selected character data entered from section 209 of coding and modulation, to generate an OFDM symbol, which is the signal on multiple carriers.

Section 211 add the prefix CF adds to the beginning of the OFDM symbol as prefix CF signal that is identical to the tail part of the OFDM symbol.

Section 212 of the radio performs transmission processing such as d / a conversion, amplification and conversion with increasing frequency for OFDM symbol after adding the prefix CF and transmits it from the antenna 201 to base station 100 (Fig. 1).

The following describes methods of placing channels Dch under this option. In the following description as an example be the case when the set of subcarriers contained in one OFDM symbol are divided equally between the 12 blocks RB #1 to #12. Also relevant blocks RB are formed channels Lch #1 to #12 and the channel Dch # on #12, moreover, the control channel used by each mobile station, by section 116 of adaptive management. The configuration of channels Lch for blocks RB shown in Fig. 3, and the configuration of the Dch channels for blocks RB, shown below, is set in advance interconnected by section 103 of the selection.

Here frequency planning for channels Lch is performed on blocks RB, and therefore in each block RB used for channel Lch, contains the character data Lch for only one mobile station. That is, one block RB forms a single channel Lch for one mobile station. Therefore, as shown in Fig. 3, the channels Lch #1 to #12 are composed by blocks RB #1 to #12. That is emitted by the unit for each channel Lch is 1 block RB × 1 Subcat".

On the other hand, for channels Dch is transmitted with frequency diversity, and therefore block RB used for channel Dch, contains many characters Dch data. Here each block RB used for channel Dch is divided in time into two subunits, and each subunit is your channel Dch. That is, in the same block RB many different Dch channels are multiplexed in the time domain. One channel Dch is formed by two different subunits RB. That is emitted by the unit for each channel Dch is "(1 unit RB×1/2 Subhadra)×2", similar to the unit of allocation for each of the CSO channel Lch.

<Method 1 placement (Fig. 4)>

When this option is placed in the same block RB are the Dch channels with consecutive channel numbers.

You will first see the relational expression for the channel numbers Dch and non RB, hosts this channel Dch.

If the number of subunits in a single block RB is Nd, the number j of block RB, hosts the channel Dch #(Nd·(k-1)+1),

Dch #(Nd·(k-1)+2), ..., Dch #(Nd·k) with consecutive channel numbers, is given by equation (1):

where k=1, 2,..., floor(Nrb/Nd); operator floor(x) represents the maximum integer not exceeding x; and Nrb is the number of blocks RB. Here, floor(Nrb/Nd) represents the amount of RB that hosts the same channel Dch.

That is, the number Nd of Dch channels containing channels with numbers #(Nd·(k-1)+1), #(Nd·(k-1)+2), ..., #(Nd·k), which are housed in the same block RB and have the serial channel of the rooms, placed a distributed way to Nd the blocks RB, RB#(j), divided by the interval floor(Nrb/Nd) in the frequency domain.

Here, since Nrb=12 and Nd=2, according to the above equation (1) we get j=k+6·p (p=0, 1), where k=1, 2,...,6. Thus, two channels Dch with consecutive channel numbers #(2k-1) and #(2k) posted by the distribution in two blocks RB #(k) and #(k+6), separated by an interval of 6 (= 12/2)blocks RB in the frequency domain.

In private the tee, as shown in Fig. 4, the channel Dch #1 and #2 is posted in block RB #1 (RB #7), Dch channels #3 and #4 is posted in block RB #2 (RB #8), Dch channels #5 and #6 are placed in the block RB #3 (RB #9), the channel Dch #7 and #8 are placed in the block RB #4 (RB #10), the channel Dch #9 and #10 are placed in the block RB #5 (RB #11) and the channel Dch #11 and #12 are placed in the block RB #6 (RB #12).

In Fig. 5 shows an example of allocating a channel allocation section 103 in the base station 100 (Fig. 1)when for a Dch data symbol of one mobile station uses four channel Dch #1 through #4. Here, the allocation section 103 supports layout Dch shown in Fig. 4, and allocates Dch data symbol blocks for RB in accordance with the layout shown in Fig. 4.

As shown in Fig. 5, allocation section 103 allocates one data symbol Dch the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #1, the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #2, the subblock of RB #2 and the subblock of RB #8 forming the channel Dch #3, and the subblock of RB #2 and the subblock of RB #8 forming the channel Dch #4. That is, as shown in Fig. 5, the Dch data symbol is allocated to the blocks RB#1, #2, #7, #8.

As shown in Fig. 5, allocation section 103 allocates the Lch data symbol to the rest of the blocks RB #3 through #6 and the blocks #9 to #12, other than blocks RB, which was selected Dch data symbol. That is, channels with Lch #3 through #6 and the channels Lch from #9 to #12, shown in Fig. 3, are used for Lch data symbol.

The following describes an example of extracting section 207 reverse PE is Emesene in the mobile station 200 (Fig. 2) for the case when the mobile station 200 selected Dch data symbol using four successive channel Dch #1 through #4. Here section 207 reverse display supports layout Dch shown in Fig. 4, as well as section 103 allocation, and allocates Dch data symbol set of blocks RB in accordance with the layout shown in Fig. 4. Information on the allocation of symbols Dch data transmitted to the mobile station 200 from the base station 100, the first channel number #1 channel Dch and the last channel #4 channel Dch.

Since channel numbers Dch indicated in the information on the allocation of Dch data symbols represent the #1 and #4, section 207 reverse display identifies the fact that the Dch channels used for a Dch data symbol addressed to this station represent four successive channel Dch #1 through #4. Then, following a similar procedure to section 103 of the selection section 207 reverse display retrieves Dch #1 generated by the subblock of RB #1 and the subblock of RB #7, Dch #2, formed by the subblock of RB #1 and the subblock of RB #7, Dch #3, formed by the subblock of RB #2 and the subblock of RB #8, and Dch #4, formed by the subblock of RB #2 and the subblock of RB #8, as shown in Fig. 5. That is, section 207 reverse display retrieves the Dch data symbol allocated to blocks RB#1, #2, #7, #8, as shown in Fig. 5 as character data, addressed to this station.

Thus, when using this method of placing the Dch channels with consecutive channel numbers are placed in the same block RB, and therefore, when one mobile station uses multiple channels Dch, are all subunits of one block RB, and then used the subunits of another block RB. This makes it possible to minimize the selection of the symbol data for some of the subunits of many subunits, forming one block RB when other subunits are not used. Therefore, according to this method of placement is possible to prevent reduction in the efficiency of resource use channel to perform transmission with frequency diversity, while simultaneously performing transmission with frequency planning channel Lch and the transmission frequency diversity in the channel Dch. Also according to this method of placement is possible to prevent reduction in the efficiency of use of the resource due RB for Dch, increasing the number of blocks RB, which may be used for channels Lch, and allowing execution frequency planning for a larger number of frequency bands.

Also according to the method of placement in the case, when one mobile station uses multiple channels Dch, many of Dch channels with consecutive channel numbers are placed in blocks RB, cat is which follow each other in the frequency domain. Therefore, blocks RB, which can be used for channels Lch (i.e. the remaining blocks RB other than blocks RB used by the channel Dch), are also consistent with the point of view of their location in the frequency domain. For example, at a moderate frequency selectivity of the channel or narrow band of frequencies of each channel, the bandwidth RB becomes narrow relative to the width of the stripe correlation with frequency-selective fading.

At the same time, blocks RB with good channel quality are located in the frequency band with high channel quality consistently. Therefore, when the bandwidth RB becomes narrow relative to the width of the stripe correlation with frequency-selective fading, the use of this method allows to use for channels Lch blocks RB, consistently located in the frequency domain, which gives the opportunity to further strengthen the effect of frequency planning.

In addition, according to the method of allocation you can allocate multiple channels Lch with consecutive channel numbers. Thus, when the base station allocates one mobile station multiple channels Lch, enough to base station said mobile station, only the first channel number and last channel number serial channel but the development. Thus, it is possible to reduce the amount of control information for reporting the result of the spin channels Lch in the same way as when reporting the result of the spin channels Dch.

When using this method of placement has been described a case where one block RB is divided in half when using channels Dch, but the number of partitions of a single block RB is not limited to two; that is, one block RB can also be divided into three or more parts. For example, in Fig. 6 shows the case of using the allocation method, when one block RB is divided into three when using channels Dch. As shown in Fig. 6, in one block RB posted three consecutive channel Dch, which allows to obtain an effect similar to the effect obtained when using this method of placement. Also, since one channel Dch is formed by the distribution between the three blocks RB, as shown in Fig. 6, the effect of diversity can be enhanced much more than in the case of the block is split in half.

<Method 2 placement (Fig. 8)>

When using this method of placement, as well as in method 1 hosting, one block RB accommodate many different channels Dch with consecutive channel numbers, but the difference from method 1 placement is that the channel Dch with the minimum or maximum number and the channel Dch with the next channel number is m from a variety of channels Dch place in the above-described one block RB and blocks RB, posted by allocation in the frequency domain.

When using this method, as with method 1 placement (Fig. 4), in the same block RB place Dch channels with consecutive channel numbers. That is, channel Dch #1 through #12, shown in Fig. 8 are formed of the combination (Dch #1, #2), (Dch #3, #4), (Dch #5, #6), (Dch #7, #8), (Dch #9, #10) and (Dch #11, #12), each of which is formed by one and the same block RB.

From among the above set of combinations in units of RB, distributed in the frequency domain, host combinations that contain the channel Dch with the minimum or maximum number included in one combination, and the channel Dch with the next channel number. That is, in various distributed blocks posted by RB (Dch #1, #2), and (Dch #3, #4), which respectively contain Dch#2 and Dch#3 with consecutive channel numbers; in different distributed blocks posted by RB (Dch #3, #4) and (Dch #5, #6), which respectively contain Dch#4 and Dch#5 with consecutive channel numbers; in different distributed blocks posted by RB (Dch #5, #6) and (Dch #7, #8), which respectively contain Dch#6 and Dch#7 with consecutive channel numbers; in different distributed blocks posted by RB (Dch #7, #8) and (Dch #9, #10), which respectively contain Dch#8 and Dch#9 with consecutive channel numbers; and in various distributed nl is Kah posted by RB (Dch #9, #10) and (Dch #11, #12), which respectively contain Dch#10 and Dch#11 with consecutive channel numbers.

Here, as in method 1 allocation, the following relational expression for channel numbers Dch and block number RB, hosts this channel Dch,

J block RB, hosts the channel Dch #(Nd·(k-1)+1), #(Nd·(k-1)+2), ..., #(Nd·k) c serial channel numbers included in the combination k, is given by equation (2):

where q(k) is a block interleaver "2 rows × (floor(Nrb/Nd)/2) columns". The number of rows of the block interleaver is assumed to be 2, but may be any positive integer less than or equal to floor(Nrb/Nd). In this way in different distributed blocks RB with different rooms are a combination of k and combination, which contains the channel Dch minimum or maximum number which is a combination of k, and the channel Dch with the subsequent channel number (combination of k-1 or combination k+1).

Here, since Nrb=12 and Nd=2, according to the above equation (2) we get j=q(k)+6·p (p=0, 1), where q(k)is a block interleaver "2 rows × 3 columns, as shown in Fig. 7. That is, as shown in Fig. 7, for k=1, 2, 3, 4, 5, 6 get q(k)=1, 4, 2, 5, 3, 6. Thus, the allocation in two blocks RB (RB #(q(k))) and (RB #(q(k)+6)), separated by an interval of 6 (=12/2) blocks RB in the frequency is blasti, put two channel Dch with consecutive channel numbers: Dch #(2k-1) and Dch #(2k).

In particular, as shown in the example in Fig. 8, in block RB #1 (RB #7) disposed channels Dch #1 and #2, in block RB #3 (RB #9) disposed channels Dch #5 and #6, in block RB #3 (RB #9) disposed channels Dch #9 and #10, block RB #4 (RB #10) disposed channels Dch #3 and #4, in block RB #5 (RB #11) disposed channels Dch #7 and #8, and block RB #6 (RB #12) disposed channels Dch #11 and #12.

As in method 1 accommodation in Fig. 9 shows an example of channel extraction section 103 allocation in the base station 100 (Fig. 1), where for a Dch data symbol of one mobile station uses four serial channel Dch #1 through #4. Here, the allocation section 103 supports the layout of Dch channels shown in Fig. 8, and allocates blocks RB Dch data symbol in accordance with the layout shown in Fig. 8.

As shown in Fig. 9, the allocation section 103 allocates Dch data symbol for the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #1, for the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #2, for the subblock of RB #4 and the subblock of RB #10, forming the channel Dch #3, and for the subblock of RB #4 and the subblock of RB #10, forming the channel Dch #4. That is, as shown in Fig. 9, the Dch data symbol is allocated to blocks RB#1, #4, #7, #10.

Also, as shown in Fig. 9, the allocation section 103 allocates the Lch data symbols for the remaining blocks RB#2, #3, #5, #6, #8, #9, #11, #12, different from blocks RB, for Kotoriba selected symbol Dch. That is, the character data channel use channels Lch Lch#2, #3, #5, #6, #8, #9, #11, #12, it is shown in Fig. 3.

Further, as in method 1 occupancy, describes an example of extracting character data section 207 reverse display in the mobile station 200 (Fig. 2) for the case when the mobile station 200 allocates Dch data symbol using four serial channel Dch #1 through #4. Here section 207 reverse display supports the layout of Dch channels shown in Fig. 8, the same as the allocation section 103, and extracts the set of blocks RB Dch data symbol in accordance with the layout shown in Fig. 8. As in method 1 placement, information on the allocation of the Dch data symbol transmitted the mobile station 200 from the base station 100 and the first channel number Dch #1 and the last channel number Dch #4.

Since channel numbers Dch indicated in the information on the allocation of Dch data symbols are #1 and #4, section 207 reverse display identifies the fact that the Dch channels used for a Dch data symbol addressed to this station, are the four serial channel Dch #1 through #4. Then, following the procedure similar to the one used by the allocation section 103, section 207 reverse display retrieves the channel Dch #1, formed by the subblock of RB #1 and the subblock of RB #7, channel Dch #2, formed subble the ohms RB #1 and the subblock of RB #7, channel Dch #3, formed by the subblock of RB #4 and the subblock of RB #10, and the channel Dch #4, formed by the subblock of RB #4 and the subblock of RB #10, as shown in Fig. 9. That is, section 207 reverse display retrieves the Dch data symbol allocated to blocks RB#1, #4, #7, #10, as shown in Fig. 9, as the symbol data addressed to this station.

When using this method of placement, as in the case of the method 1, the Dch data symbol is allocated to four blocks RB, and Lch data symbol is allocated to eight blocks RB. However, when using this method of placing the Dch data symbol is allocated by the allocation for each of the three blocks RB (RB #1, RB #4, RB #7 and RB #10), as shown in Fig. 9, which allows us to increase the frequency diversity effect is much better than using method 1 placement (Fig. 5). Also, as shown in Fig. 9, the selection of the Dch data symbol allocated blocks RB also means that there is a distribution of Lch data symbol that gives the ability to perform frequency planning using blocks RB over a wide band of frequencies.

Thus, when using this method of placement in the same block RB, where many different channels Dch with consecutive channel numbers, and blocks RB, distributed in the frequency domain, host channel Dch with the minimum or maximum of the number and the channel Dch with the subsequent channel number from many different channels Dch. Therefore, even if the data symbol of one mobile station uses multiple channels Dch, it is possible to prevent the use of certain subunits RB and highlight character data distributed over a wide band of frequencies. Thus, according to this way of placement can be obtained the same kind of effect as when using method 1 occupancy, and may be further reinforced the effect of frequency diversity. Also when using this method of placing blocks RB used for Dch channels are distributed, which allows to distribute the blocks RB than the ones used for Dch channels (i.e. blocks RB used for channels Lch). The result, according to the method of placement can enhance the effect of frequency planning.

When using this method of allocation was described a case where one block RB is divided in half when using channels Dch; but one block RB is not necessary to divide in half, meaning that it can be divided into three or more parts. In Fig. 10 shows an example of the method of allocation of channels for the case where one block RB is divided into three parts when using channels Dch. As shown in Fig. 10, the various blocks RB, which includes the serial Dch channels are distributed in the frequency domain, which allows to obtain the same ro is and the effect, as when using the described method. Also, since one channel Dch is formed by the distribution between the three blocks RB, as shown in Fig. 10, it is possible to achieve a stronger effect explode, than in the case of dividing the block in half.

<Method 3 placement (Fig. 11)>

When using this method, the Dch channels with consecutive channel numbers are allocated to different blocks RB, and in the same block RB are the Dch channels with channel numbers within a predetermined number.

Below this method is described with specific details. Here it is assumed that the predetermined number is equal to 2. That is, the difference in channel numbers different channels Dch included in the same block RB, does not exceed 2.

You will first see the relational expression for the channel numbers Dch and block number RB, hosts this channel Dch.

J block RB, hosts differ from other channels Dch included in the combination k, is given by equation (2) in the same manner as in method 2 placement. However, while using method 2 host channel Dch channel numbers included in the combination k, are consistent with this way of placing the Dch channel numbers included in the combination k, are within a predetermined number Also for the combination of channels Dch with lower channel numbers is assigned a number k with a smaller value.

Here, since Nrb=12 and Nd=2, j=q(k)+ 6·p (p=0, 1), as well as when using method 2 occupancy, where q(k) is a block interleaver "2 rows × 3 columns, is shown in Fig. 7, as well as when using method 2 for placement. Thus, the Dch channels included in the combination k, are distributive in two blocks RB #(q(k)) and #(q(k)+6), separated by an interval of 6 (=12/2)blocks RB in the frequency domain. However, since the predetermined number is equal to 2, the combination 1 (k=1) is a (Dch #1, #3), and the combination of the 2 (k=2) is a (Dch #2, #4). The above explanation can be extended to combinations of 3 through 6.

Thus, as shown in Fig. 11, in block RB #1 (RB #7) disposed channels Dch #1 and #3, in block RB #2 (RB #8) disposed channels Dch #5 and #7, in block RB #3 (RB #9) disposed channels Dch #9 and #11, block RB #4 (RB #10) disposed channels Dch #2 and #4, in block RB #5 (RB #11) disposed channels Dch #6 and #8 and block RB #6 (RB #12) disposed channels Dch #10 and #12.

In Fig. 12 shows an example of allocating section 103 allocation of channels in the base station 100 (Fig. 1)when for a Dch data symbol of one mobile station uses two serial channels Dch (Dch #1 and Dch #2), that is, when the number of Dch channels used for a Dch data symbol of one mobile station, a little. Here, the allocation section 103 supports the layout of Dch channels shown in Fig. 11, and selects the end-of-the Dch data blocks for RB according to the layout, it is shown in Fig. 11.

As shown in Fig. 12, allocation section 103 allocates Dch data symbol for the subblock of RB #1 and the subblock of RB #7, forming a channel Dch #1, and the subblock of RB #4 and the subblock of RB #10, forming a channel Dch #2. That is, as shown in Fig. 12, the Dch data symbol is allocated to blocks#1, #4, #7, #10, distributed in the frequency domain.

The following describes an example of extracting character data section 207 reverse display in the mobile station 200 (Fig. 2) for the case when the mobile station 200 allocates Dch data symbol using two serial channels Dch #1 and #2. Here section 207 reverse display supports layout Dch shown in Fig. 11, in the same way as the allocation section 103, and extracts the character data Dch set of blocks RB according to the layout shown in Fig. 11. Information on the allocation of the Dch data symbol transmitted from base station 100 to the mobile station 200 are listed first channel number Dch #1 and the last channel number Dch #2.

Since channel numbers Dch indicated in the information on the allocation of the symbol data Dch, Dch are #1 and Dch #2, section 207 reverse display identifies the fact that the Dch channels used for a Dch data symbol addressed to this station, are two serial channel Dch #1 and #2. Then, following a similar procedure executing section 103 separation of the Oia, section 207 reverse display retrieves the channel Dch #1, formed by the subblock of RB #1 and the subblock of RB #7, and the channel Dch #2, formed by the subblock of RB #4 and the subblock of RB #10, as shown in Fig. 12. That is, section 207 reverse display retrieves the Dch data symbol allocated to blocks RB#1, #4, #7, #10, distributed in the frequency domain, as shown in Fig. 12, as the symbol data addressed to this station.

Thus, when the number of Dch channels used for a Dch data symbol of one mobile station is small, i.e. when there are multiple selected blocks RB, the less efficient use of communication resources for the entire frequency band to be insignificant. Consequently, it is possible to benefit from the frequency diversity effect, despite the likelihood that the subunits other than the sub-blocks allocated in blocks RB will not be used.

On the other hand, in Fig. 13 shows an example of allocating section 103 allocation in the base station 100 (Fig. 1)when for a Dch data symbol of one mobile station uses four serial channel Dch #1 to #4, that is, when the number of Dch channels used for a Dch data symbol of one mobile station, great. Here, the allocation section 103 supports layout Dch shown in Fig. 11, and allocates Dch data symbol blocks RB according to the layout, is provided in Fig. 11.

As shown in Fig. 12, allocation section 103 allocates Dch data symbol for the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #1, for the subblock of RB #4 and the subblock of RB #10, forming the channel Dch #2, for the subblock of RB #1 and the subblock of RB #7, forming the channel Dch #3, and for the subblock of RB #4 and the subblock of RB #10, forming the channel Dch #4. That is, as shown in Fig. 12, the Dch data symbol is allocated to blocks RB#1, #4, #7, #10, distributed in the frequency domain, as shown in Fig. 12. Also in Fig. 13 Dch data symbol allocated to all sub-blocks of the blocks RB#1, #4, #7, #10.

The following describes an example of extracting character data section 207 reverse display in the mobile station 200 (Fig. 2) for the case when the mobile station 200 allocates Dch data symbol using four serial channels Dch #1 through #4. Here section 207 reverse display supports layout Dch shown in Fig. 11, in the same way as the allocation section 103, and extracts the character data Dch set of blocks RB according to the layout shown in Fig. 11. Information on the allocation of the Dch data symbol transmitted from base station 100 to the mobile station 200 are listed first channel number Dch #1 and the last channel number Dch #4.

Since channel numbers Dch indicated in the information on the allocation of the symbol data Dch, Dch are #1 and Dch #4, section 207 reverse display identifies the fact is that channels Dch, used for a Dch data symbol addressed to this station, are the four serial channel Dch #1 through #4. Then, following a similar procedure performed by the allocation section 103, section 207 reverse display retrieves the channel Dch #1, formed by the subblock of RB #1 and the subblock of RB #7, channel Dch #2, formed by the subblock of RB #4 and the subblock of RB #10, channel Dch #3, formed by the subblock of RB #1 and the subblock of RB #7, and the channel Dch #4, formed by the subblock of RB #4 and the subblock of RB #10, as shown in Fig. 13. That is, section 207 reverse display retrieves the Dch data symbol allocated to all sub-blocks of the blocks RB#1, #4, #7, #10, as shown in Fig. 13, as the symbol data addressed to this station.

Thus, when the number of Dch channels used for a Dch data symbol of one mobile station is large (i.e. there is a lot of allocated blocks RB), can be used all the subunits in blocks RB with obtaining the frequency diversity effect.

Thus, when using this method of placing the Dch channels with sequential numbers are placed in different blocks RB, and in the same block RB are the Dch channels with channel numbers within a predetermined number. Thanks this may be enhanced by the effect of frequency diversity with a small number of Dch channels used for a Dch data symbol of one mobile is tanzihi. Also, even if the number of Dch channels used for a Dch data symbol of one mobile station is large, the effect of frequency diversity can be enhanced without reducing the efficiency of use of communication resources.

When using this method of placement has been described a case where one block RB is divided in half when using channels Dch, but the number of partitions of a single block RB is not limited to two, and one block RB can also be divided into three or more parts. For example, in Fig. 14 shows the case of using the allocation method, when one block RB is divided into three parts when using channels Dch. As shown in Fig. 14, the Dch channels with consecutive channel numbers are placed in different blocks RB, and one RB posted by the channel numbers within a predetermined number equal to two, which allows to obtain an effect similar to the effect obtained when using this method of placement. Also, since one channel Dch is formed by the distribution between the three blocks RB, as shown in Fig. 14, the effect of diversity can be enhanced much more than in case of division by two.

<Method 4 placement (Fig. 15)>

When using this method of placing many different channels Dch with consecutive channel numbers are placed in the same block RB is exactly the same as in method 1 is asemenea, but unlike method 1 hosting is that blocks RB, which are placed in the same channel Dch, are allocated in the order from both ends of the strip.

When using this method of placement, as in method 1 placement (Fig. 4), the Dch channels with consecutive channel numbers are placed in the same block RB. That is, channel Dch #1 through #12, shown in Fig. 15, the combinations of channels Dch (Dch #1, #2), (Dch #3, #4), (Dch #5, #6), (Dch #7, #8), (Dch #9, #10) and (Dch #11, #12), and each combination produces the same block RB.

Two blocks RB, which are placed in the channels Dch of the above combinations, produce order from both ends of the strip. That is, as shown in Fig. 15, the combination of (Dch #1, #2) is placed in blocks RB #1 and #12, and the combination of (Dch #3, #4) is placed in blocks RB #2 and #11. Similarly, the combination of (Dch #5, # 6) is placed in blocks RB #3 and #10, a combination of (Dch #7, #8) is placed in blocks RB #4 and #9, the combination of (Dch #9, #10) is placed in blocks RB #5 and #8, and the combination of (Dch #11, #12) is placed in blocks RB #6 and #7.

As in method 1 accommodation in Fig. 16 shows an example of allocating a channel allocation section 103 in the base station 100 (Fig. 1), where for a Dch data symbol of one mobile station uses four serial channel Dch #1 through #4. Here, the allocation section 103 supports the layout of Dch channels shown in Fig. 15 and allocates blocks for RB Dch data symbol in accordance with a layout, it is shown in Fig. 15.

As shown in Fig. 16, allocation section 103 allocates Dch data symbol for the subblock of RB #1 and the subblock of RB #12 forming the channel Dch #1, for the subblock of RB #1 and the subblock of RB #12 forming the channel Dch #2, for the subblock of RB #2 and the subblock of RB #11 forming the channel Dch #3, and for the subblock of RB #2 and the subblock of RB #11 forming the channel Dch #4. That is, as shown in Fig. 16, the Dch data symbol is allocated to blocks RB#1, #2, #11, #12.

Also, as shown in Fig. 16, allocation section 103 allocates the Lch data symbols for the remaining blocks RB#3, #4, #5, #6, #7, #8, #9, #10, different from blocks RB for which was highlighted character Dch. That is, the character data channel use channels Lch Lch#3, #4, #5, #6, #7, #8, #9, #10, it is shown in Fig. 3.

Further, as in method 1 occupancy, describes an example of extracting character data section 207 reverse display in the mobile station 200 (Fig. 2) for the case when the mobile station 200 allocates Dch data symbol using four serial channel Dch #1 through #4. Here section 207 reverse display supports the layout of Dch channels shown in Fig. 15, the same as the allocation section 103, and extracts the set of blocks RB Dch data symbol in accordance with the layout shown in Fig. 15. As in method 1 placement, information on the allocation of the Dch data symbol transmitted the mobile station 200 from the base station 100 specifies p the pout channel number Dch #1 and the last channel number Dch #4.

Since channel numbers Dch indicated in the information on the allocation of Dch data symbols are #1 and #4, section 207 reverse display identifies the fact that the Dch channels used for a Dch data symbol addressed to this station, are the four serial channel Dch #1 through #4. Then, following the procedure similar to the one used by the allocation section 103, section 207 reverse display retrieves the channel Dch #1, formed by the subblock of RB #1 and the subblock of RB #12, the channel Dch #2, formed by the subblock of RB #1 and the subblock of RB #12, the channel Dch #3, formed by the subblock of RB #2 and the subblock of RB #11, and the channel Dch #4, formed by the subblock of RB #2 and the subblock of RB #11, as shown in Fig. 16. That is, section 207 reverse display retrieves the Dch data symbol allocated to blocks RB#1, #2, #11, #12, as shown in Fig. 16, as the symbol data addressed to this station.

When using this method of placement, as in the case of the method 1 allocation and method 2 occupancy, the Dch data symbol is allocated to four blocks RB, and Lch data symbol is allocated to eight blocks RB. However, when using this method of placing the Dch data symbol is allocated to blocks RB with both ends of the strip as shown in Fig. 16. Since the interval RB, which allocates Dch data symbol, is wider than in the case of method 1 placement (Fig. 5) Il is the way 2 placement (Fig. 9), the effect of frequency diversity can be enhanced. As shown in Fig. 16, the selection of the Dch data symbol blocks for RB at both ends of the strip also means that there is a distribution of Lch data symbol that gives the ability to perform frequency planning using blocks RB over a wide band of frequencies.

Also according to this way of placing all the blocks RB, which can be used for channels Lch (i.e. the remaining blocks RB different from those used by the channel Dch), are consistent with the point of view of frequency. For example, at a moderate frequency selectivity of the channel or narrow band of each channel, the bandwidth RB becomes narrow relative to the width of the stripe correlation with frequency-selective fading. At the same time, blocks RB with good quality channel sequentially located in a frequency band with a high quality channel. Therefore, when the bandwidth RB is narrow relative to the width of the stripe correlation with frequency-selective fading, the use of this method allows to use for channels Lch blocks RB, consistently located in the frequency domain, which gives the opportunity to further strengthen the effect of frequency planning.

In addition, according to this way of placing you can select multiple to the channels Lch with consecutive channel numbers. Thus, when the base station allocates one mobile station multiple channels Lch, enough to base station said mobile station, only the first channel number and last channel number of the number of consecutive channel numbers. When using this way of placing all the blocks RB, which can be used for channels Lch, are placed sequentially in the frequency domain, and therefore even in the case when all channels Lch allocated to one mobile station, it is possible to use the above method of message information. Thus, it is possible to reduce the amount of control information for reporting the result of the spin channels Lch in the same way as when reporting the result of the spin channels Dch.

When using this method of placement has been described a case where one block RB is divided in half when using channels Dch, but the number of parts to divide one block RB, is not limited to two, and one block RB can also be divided into three or more parts. For example, in Fig. 17 and Fig. 18 accordingly shown when one block RB is divided into three and four when using channels Dch. As shown in Fig. 17 and Fig. 18, the various blocks RB, which includes the serial Dch channels, preferably placed on both ends of the strip, which allows the floor is a raised effect similar to the effect obtained when using this method of placement. Also, since one channel Dch is formed by the distribution between the three blocks RB or four blocks RB, as shown in Fig. 17 and Fig. 18 accordingly, the effect of diversity can be enhanced to a much greater extent than in the case of division into two.

This ends the description of ways of placing 1 through 4 under this option.

Thus, under this option it is possible to prevent reduction in the efficiency of resource use communication channel to perform transmission with frequency diversity, while simultaneously performing transmission with frequency planning in the channel Lch and the transmission frequency diversity in the channel Dch. Also, under this option it is possible to prevent reduction in the efficiency of block RB used for channel Dch, increasing the number of blocks RB, which can be used for channels Lch, and allowing execution frequency planning for additional frequency bands.

(Option 2)

In this embodiment describes the case when the switches between mode 1 accommodation options 1 and method 2 allocation option 1, depending on environment connection.

As described above, method 1 allows to use more blocks RB, successive castetnau region, which can be used to provide channels Lch than method 2 occupancy, although method 2 placement is most effective frequency diversity than method 1 host.

In particular, when using four serial channels Dch #1 through #4 for a Dch data symbol of one mobile station, when using method 1 placement (Fig. 5) for channel Lch, you can use four blocks RB, following each other in the frequency domain, blocks RB #3 through #6 and blocks RB #9 to #12, while the Dch data symbol is allocated to two blocks RB, following each other in the frequency domain, RB #1, #2 and RB #7, #8. On the other hand, when using method 2 placement (Fig. 9) for channel Lch is possible to use only two blocks RB, consistently placed in the frequency domain RB #2, #3, RB #5, #6, RB #8, #9 and RB #11, #12, while the Dch data symbol is allocated by distributing each of three blocks RB, RB#1, #4, #7, #10.

Thus, when using method 1 allocation and method 2 placement is a compromise between the effect of frequency diversity and the number of blocks RB, consecutive in the frequency domain, which can be used for channels Lch.

Section 103 of the selection according to this variant (Fig. 1) performs switching between method 1 accommodation options 1 and method 2 allocation option 1 depending on sidesway and respectively allocates Dch data symbol and the symbol data for Lch block RB.

The following describes how to switch from 1st to 3rd used by section 103 of the selection for this option.

<Method 1 switch>

When using this method of switching the method of placement is selected in accordance with the number of parts, which is divided block RB. In the following description, the number of parts, which is divided block RB, denoted as Nd.

The larger the value of Nd, the greater the number of different blocks RB, which are placed in the same channel Dch. For example, when using method 1 occupancy, when Nd=2, the same channel Dch is distributed across two different blocks RB, as shown in Fig. 4, whereas, when Nd=4, the same channel Dch is distributed across four different blocks RB, as shown in Fig. 19. Thus, the larger the value of Nd, the greater the number of different blocks RB, in which by distributing posted the same channel Dch, and, consequently, the greater will be the effect of frequency diversity. In other words, the smaller the value of Nd, the less the effect of frequency diversity.

At the same time, the smaller the value of Nd, the more the frequency interval between the various blocks RB, which are placed in the same channel Dch. For example, when using method 1 occupancy, when Nd=2, the frequency interval of the sub-blocks, formiruyushchego the same channel Dch, will be equal to six blocks RB, as shown in Fig. 4, whereas, when Nd=4, the frequency interval of the subunits forming the same channel Dch, will be equal to three blocks RB. Thus, the smaller the value of Nd, the more the frequency interval of the subunits forming the same channel Dch, and, accordingly, the more blocks RB, consecutive in the frequency domain, it is possible to secure channels Lch. In other words, the larger the value of Nd, the smaller the number of blocks RB, consecutive in the frequency domain, which can be used for channels Lch.

Thus, allocation section 103 allocates Dch channels using method 1 placement when the value of Nd is large (i.e. when the number of blocks RB, consecutive in the frequency domain, which can be used for channels Lch, little), and allocates Dch channels using method 2 occupancy, when the value of Nd is small enough, i.e. when the frequency diversity effect is small). In particular, the allocation section 103 switches from one host to another based on the comparison Nd c predefined threshold value. That is, section 103 of the placement proceeds to method 1 occupancy, when Nd is greater than or equal to the threshold value, and turns on the way 2 occupancy, when Nd is less than a specified threshold value.

As in in the version 1, in Fig. 20 shows an example of allocating, when for Dch data symbol of one mobile station uses four serial channel Dch #1 through #4. Here is described a case when a predetermined threshold value, is equal to 3, when Nd=4 (number of parts is large), and the case when Nd=2 (number of parts are few). When Nd=2, the situation is analogous to using method 2 allocation for option 1 (Fig. 9), and therefore its description is omitted.

When Nd=4, as shown in Fig. 20, allocation section 103 allocates Dch data symbol for the subblock of RB #1, subblock of RB #4, the subblock of RB #7 and the subblock of RB #10, forming a channel Dch #1; for the subblock of RB #1, subblock of RB #4, the subblock of RB #7 and the subblock of RB #10, forming a channel Dch #2; for the subblock of RB #1, subblock of RB #4, the subblock of RB #7 and the subblock of RB #10, forming a channel Dch #3; and for the subblock of RB #1, subblock of RB #4, the subblock of RB #7 and the subblock of RB #10, forming a channel Dch #4, according to the method 1 placement (Fig. 19). That is, as shown in Fig. 20, the Dch data symbol is allocated to blocks#1, #4, #7, #10.

Also, as shown in Fig. 20, allocation section 103 allocates the Lch data symbols for the remaining blocks RB#2, #3, #5, #6, #8, #9, #11, #12, different from those blocks RB, which was selected Dch data symbol. That is, the character data use channels Lch Lch#2, #3, #5, #6, #8, #9, #11, #12.

Thus, when using this method of switching, in both cases, when Nd=4 (Fig. 20), and when Nd=2 (Fig. 9), SIM the ol data Dch is allocated for blocks RB #1, #4, #7, #10, and Lch data symbol is allocated to blocks RB#2, #3, #5, #6, #8, #9, #11, #12.

That is, when the value of Nd is large (when the number of blocks RB, consecutive in the frequency domain, which can be used for channels Lch, little), using method 1 allows to provide the maximum number of consecutive in the frequency domain blocks RB, which can be used for channels Lch when the effect of frequency diversity. On the other hand, when the value of Nd is small (when the frequency diversity effect is small), using method 2 allows to enhance the effect of frequency diversity, while fixing blocks RB, consecutive in the frequency domain, which can be used for channels Lch.

Thus, according to this method of switching, when the number of parts, which is divided block RB, great, switch on the method of placement, the use of which preferably receive blocks RB, consistently located in the frequency domain, which can be used for channels Lch, while a small number of parts to split one block RB, is the way of placement, the use of which preferably have the effect of frequency diversity. The way in abiraterone cases, on a number of parts, which divided one block RB may be magnified as the frequency diversity effect, and the effect of frequency planning. Also according to the method of switching channels Lch used in transmission with frequency planning, are fixed in blocks RB, consecutive in the frequency domain, thereby reducing the size of control information for reporting the distribution channels Lch.

Also according to this method of switching, the greater the number of mobile stations or the number of Dch channels, the greater the value of Nd, which you can use. Thus, when the number of mobile stations or the number differing from each channel Dch is large, the same channel Dch is allocated for a larger number of different blocks RB that can further enhance the effect of frequency diversity for a single channel Dch. On the other hand, when the number of mobile stations or the number differing from each channel Dch is small, the number differing from other channels Dch for one block RB decreases, which helps prevent free places, resulting in some subunits, and avoids reducing the efficient use of communication resources. For example, when Nd=4, in some subunits of one block RB is shown Auda available space when the number of different channels Dch, less four. However, if you make the value of Nd is less than 4, it will increase the likelihood of use of all sub-blocks contained in one block RB that will not compromise the efficient use of communication resources.

<Method 2 switching>

When using this method of switching the method of placement is selected depending on the channel status, such as frequency selectivity of the channel.

At a moderate frequency selectivity is observed trend is consistent location in the frequency domain blocks RB with high quality channels, which makes this situation suitable for transmission with frequency planning. On the other hand, when a significant frequency selectivity is observed distribution in the frequency domain channels RB with high channel quality, which makes this situation suitable for transmission with frequency diversity.

Thus, allocation section 103 allocates Dch channels using method 1 for placement at a moderate frequency selectivity and allocates Dch channels using method 2 occupancy, with significant frequency selectivity.

At a moderate frequency selectivity (when blocks RB with high channel quality are consistently located in the frequency domain) using method 1 allows use is for channels with Lch blocks RB, consistently located in the frequency domain, which gives the opportunity to enhance the effect of frequency planning. Also, since the channels Lch fixed in blocks RB, consecutive in the frequency domain, you can reduce the amount of control information for reporting the result of the spin channels Lch.

On the other hand, when a significant frequency selectivity (when blocks RB with high channel quality is distributed in the frequency domain) using method 2 allocation leads to the selection of channels Lch by their distribution in the frequency domain, which allows to perform frequency planning using blocks RB with high channel quality, which is distributed over a wide band of frequencies.

Thus, according to the method of switching the selection of the allocation is made based on the frequency selectivity, and therefore, whatever the situation with the frequency selectivity, the effect of frequency planning for channels Lch can be amplified along with the effect of frequency diversity for channels Dch.

Used in this way, the switching frequency selectivity can be measured, for example, by dispersion channel delay (variation of delay).

In addition, since the frequency selectivity differs depending the tee from the cell size and condition of connection in a cell, this type of switch can be used on Postovoi the basis and method of placement also choose to Postovoi basis. In addition, since the frequency selectivity for each mobile station are different, this method of switching is applicable to each individual mobile station.

<3 Way switch>

When using this method of switching the method of allocation chosen depending on the bandwidth of the system, i.e. bandwidth, in which there is an allocation blocks RB.

Than the system bandwidth, the less the frequency interval between blocks RB used for Dch channels. Therefore, the effect of frequency diversity is not increased, however, in the frequency domain is allocated multiple channels Dch distributed way. On the other hand, the wider system bandwidth, the greater the frequency interval between blocks RB used for Dch channels. Therefore, when the frequency domain is the set of channels Dch distributed to channels Lch may be assigned a large number of blocks RB, consecutive in the frequency domain, is proportional to the frequency interval between blocks RB used for Dch channels, which allows to obtain the effect of frequency planning.

Thus, section 103 separation of the Oia allocates channels Dch, using method 1 placement in a narrow system bandwidth, and allocates Dch channels using method 2 placement under a wide system bandwidth.

In this way when there is a narrow system bandwidth using method 1 allows, it is preferable to secure the blocks RB, consistently located in the frequency domain, which can be used for channels Lch, without obtaining the frequency diversity effect. On the other hand, if the wide system bandwidth using method 2 allows to enhance the effect of frequency diversity, without weakening the effect of frequency planning.

Thus, according to the method of switching the method of allocation chosen in accordance with the width of the system bandwidth, and so you can always get the optimal effect of frequency planning, whatever the width of the system bandwidth. Also, since the channels Lch are fixed in blocks RB, consecutive in the frequency domain, you can reduce the amount of control information for reporting the distribution channels Lch.

This concludes the description of how to switch from 1 to 3 used in section 103 of the selection for this option.

Thus, according to this variant, the switching from one way of placing the Dch channels on others the Goy is performed depending on the communication environment, that always helps transfer with frequency planning Lch and transmission with frequency diversity Dch in accordance with the communication environment.

In this embodiment have been described cases where switching from one host to another is performed by the allocation section 103 (Fig. 1), but switching from one host to another is not necessarily executed by the allocation section 103. For example, switching from one host to another can be done by the section switching from one mode to another (not shown) in accordance with the communication environment, and this section may choose the way of accommodation to be used by section 103 of the selection.

Also in this embodiment have been described cases where the allocation section 103 (Fig. 1) selects between method 1 allocation and method 2 but section 103 of the host can provide an effect similar to that described above, and the effect disclosed in the description of method 3 placement for option 1, method 3 placement for option 1 instead of option 2 placement. Section 103 allocation can also perform switching between methods of placing 1 to 3 in accordance with the communication environment.

In addition, in this embodiment, when performing switching from one host to another can be a transition between the relational expression (equation (1) and equation (2)), reflecting the relationship between the channel number of the Dch and the block number RB, in which the channel Dch posted, or variable relational expression, for example, q(k). Also in this embodiment, the mobile station may be sent a message about the specified variables in relational expressions. Thanks to this mobile station can switch to the appropriate way of placing with each switch from one host to another and, therefore, may determine the allocated channel Dch.

(Option 3)

In this embodiment describes the case where a single block RB posted only one channel Dch (number of parts, which divided one block RB, equal to one).

You will first see the relational expression for the channel numbers Dch and block number RB, hosts this channel Dch.

J block RB, hosts the channel Dch channel number k, is given by equation (3):

where k=1, 2..., Nrb, and q(k) is a block interleaver "M rows × (NBR/M) columns, where M is an arbitrary positive integer.

If we assume that the Nrb=12 and M=4, then q(k) is a block interleaver "4 rows × 3 columns, as shown in Fig. 21. That is, as shown in Fig. 21, for k=1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 the floor is named q(k)=1, 7, 4, 10, 2, 8, 5, 11, 3, 9, 6, 12. Thus, the channel Dch #(k) is by distributing block RB #(q(k)).

In particular, as shown in Fig. 22, Dch #1 is in RB #1, Dch #5 is in RB #2, Dch #9 is in RB #3, Dch #3 is in RB #4, Dch #7 is in RB #5, Dch #11 is placed in RB #6, Dch #2 is in RB #7, Dch #6 is in RB #8, Dch #10 is placed in RB #9, Dch #4 is in RB #10, Dch #8 is in RB #11 and Dch #12 is placed in RB #12.

Thus, when using channels Lch (Fig. 3) channels Lch #1 to #12 with consecutive channel numbers are placed in order in blocks RB #1 to #12, while when using channels Dch (Fig. 22) the Dch channels with consecutive channel numbers are placed in blocks RB, which are available through distribution in the frequency domain. That is, for each block RB #1 to #12 have different channel numbers when using channels Lch and when using channels Dch.

As with scenario 1, Fig. 23 shows an example of allocating section 103 allocation in the base station 100 (Fig. 1) when used for a Dch data symbol of one mobile station four serial channels Dch #1 through #4. Here, the allocation section 103 supports the layout of Dch channels shown in Fig. 22, and allocates Dch data symbol blocks for RB in accordance with the layout shown in Fig. 22.

As shown in Fig. 23, section 103 you the population allocates Dch data symbol block RB #1, hosts Dch #1, block RB #7, which is placed Dch #2, block RB #4, which is placed Dch #3, and block RB #10, hosts Dch #4. That is, as shown in Fig. 23, the Dch data symbol allocated to blocks RB#1, #4, #7, #10.

Also, as shown in Fig. 23, allocation section 103 allocates the Lch data symbols for the remaining blocks RB#2, #3, #5, #6, #8, #9, #11, #12, different from blocks RB, which was highlighted character Dch. That is, the character data channel use channels Lch Lch#2, #3, #5, #6, #8, #9, #11, #12, it is shown in Fig. 3.

Further, as in embodiment 1 describes an example of extracting character data section 207 reverse display in the mobile station 200 (Fig. 2) for the case when the mobile station 200 allocates Dch data symbol using four serial channel Dch #1 through #4. Here section 207 reverse display supports the layout of Dch channels shown in Fig. 22, the same as the allocation section 103, and extracts the set of blocks RB Dch data symbol in accordance with the layout shown in Fig. 22. Information on the allocation of the Dch data symbol transmitted the mobile station 200 from the base station 100, the first channel number Dch #1 and the last channel number Dch #4.

Since channel numbers Dch indicated in the information on the allocation of Dch data symbols are #1 and #4, section 207 reverse display your identify is the duty to regulate the fact, what channels Dch used for a Dch data symbol addressed to this station, are the four serial channel Dch #1 through #4. Then, following the procedure similar to the one used by the allocation section 103, section 207 reverse display retrieves the channel Dch #1, placed in the block RB #1, channel Dch #2, located in block RB #7, channel Dch #3, located in block RB #4, and channel Dch #4 placed in the block RB #10, as shown in Fig. 23. That is, section 207 reverse display retrieves the Dch data symbol allocated to blocks RB#1, #4, #7, #10, as shown in Fig. 23, as the symbol data addressed to this station.

In this embodiment, as in the case of using the method of placing 1 to 3 in embodiment 1, the Dch data symbol is allocated to four blocks RB, and Lch data symbol is allocated to eight blocks RB. Also in this embodiment, the Dch data symbol is allocated by the allocation for each of the three blocks RB (RB #1, RB #4, RB #7 and RB #10), as shown in Fig. 23, which helps to enhance the effect of frequency diversity. In addition, as shown in Fig. 23, the selection of the Dch data symbol allocated blocks RB also means that there is a distribution of Lch data symbol that gives the ability to perform frequency planning using blocks RB over a wide band of frequencies.

Thus, in this embodiment, in the same block RB posted by only the n channel Dch, and many different channels Dch with consecutive channel numbers are placed in blocks RB, which are available through distribution in the frequency domain. Because of this, selecting one mobile station multiple channels Dch, not completely eliminated the use of some blocks RB, and can be obtained the effect of frequency diversity.

Also according to this variant channels Dch with consecutive channel numbers are placed in blocks RB, which are available through distribution in the frequency domain, but the pre-established mutual displaying channel numbers Dch and numbers RB, thus reducing the amount of control information for reporting the result of the spin channels Dch in the same manner as provided in option 1.

(Option 4)

In this embodiment describes the case when switching between mode 1 host and 4 way accommodation for option 1 is performed in accordance with the number (Nd) parts (subunits), which is divided into one block RB.

As described above, the method 4 allows to secure a larger number of blocks RB, consecutive in the frequency domain, which can be used for channels Lch than method 1 host.

On the other hand, when using a large number of Dch channels with mode 4 placement interval mesubachi RB, which are placed in the channels Dch, is very different depending on the channel Dch, and therefore the effect of frequency diversity due to the Dch channels is obtained inhomogeneous. In particular, in Fig. 15 channel Dch #1 placed in blocks RB #1 and #12, and therefore, the interval is 11 blocks RB, and therefore, there is a large frequency diversity effect, but the channel Dch #12 placed in blocks RB #6 and #7, and therefore the interval is 1, and the frequency diversity effect is small.

On the other hand, when using method 1 allocation interval between blocks RB, which posted one channel Dch is homogeneous, which allows to obtain a homogeneous effect of frequency diversity, regardless of the channel Dch. Also, as was established above (method 1 switch), through the use of a larger value of Nd, the greater the number of mobile stations or the number of Dch channels you can further enhance the effect of frequency diversity while simultaneously preventing a decrease in the efficiency of use of communication resources.

Thus, in this embodiment, the allocation section 103 allocates Dch channels using method 1 placement when the value of Nd is large (i.e. when there is more channels Dch), and allocates Dch channels using method 4 placement when the value of Nd is small enough, i.e. when there is less channels Dch). In an hour the particular the allocation section 103 performs switching from one host to another based on the comparison Nd a predetermined threshold value. That is, section 103 of the placement proceeds to method 1 occupancy, when Nd is greater than or equal to the threshold value, and turns on the way 4 occupancy, when Nd is less than a specified threshold value.

For example, if Nd=2 is used, the placement of the Dch channels shown in Fig. 15, and when Nd=4 is used accommodation, shown in Fig. 19.

In this way, you can enhance the effect of frequency diversity, regardless of whether big or small is the number of Dch channels. That is, when the value of Nd is large (when a large number of channels Dch), is accepted accommodation option, which allows you to get a good frequency diversity uniformly for all channels Dch, and when the value of Nd little (little number of channels Dch), is accepted accommodation to enhance the effect of frequency diversity for a particular channel Dch. Here with a small number of Dch channels uneven frequency diversity effect when using method 4 of accommodation is not a problem, if it is preferable to use the Dch channels in the vicinity of both ends of the frequency band (i.e., the Dch channels with small numbers in Fig. 15).

Using method 4 placement at small value Nd (the ri small number of Dch channels) allows for a greater number of consecutive blocks RB for Lch and allows you to use the way of reporting the allocation of consecutive blocks RB for a larger number of channels Lch. When the number of mobile stations is small, one mobile station often takes a large number of blocks RB in the implementation of communication and, therefore, there is a large effect of improving the efficiency of communication. Using method 1 hosting for large values of Nd (with a large number of Dch channels) allows for a more distributed blocks RB for channels Lch. With a large number of mobile stations, the more distributed channels Lch is allocated for the use of resources by multiple mobile stations, the stronger the effect of frequency planning and, therefore, further increases the efficiency of communication.

Since the ratio between the number of mobile stations using channels Dch, and the number of mobile stations using channels Lch, usually constant and does not depend on the total number of mobile stations discussed option is effective.

Thus, according to this option, get a good frequency diversity effect regardless of the number of mobile stations while potentially increasing the effectiveness of communication.

(Option 5)

In this embodiment, as in method 3 placement for option 1, the Dch channels with consecutive channel numbers are placed in different blocks RB, and the Dch channels with channel numbers within a predetermined h the ultralights are placed in one block RB, however, the channels Dch place using another block interleaver different from the one used in method 3 placement for option 1.

This option is described below with specific details. Here, when using method 3 placement for option 1, assuming Nrb=12, Nd=2, and the predetermined number is equal to 2. Also channels Lch #1 to #12 or channels Dch #1 through #12 are formed by blocks RB.

In this embodiment, channel Dch non specified block interleaver "3 rows × 4 columns shown in Fig. 24. In particular, the block interleaver shown in Fig. 24, entered channel number k=1, 2,..., Nrb channel Dch, and output channel numbers j(k) channels Dch. That is, the block interleaver shown in Fig. 24, performs a reflow channel numbers Dch. Then, if k≤floor(Nrb/Nd), block numbers RB, which are placed in the channel Dch #(j(k))will be a #(k) and #(k+floor(Nrb/Nd)). On the other hand, if k>floor(Nrb/Nd), RB rooms, which are placed in the channel Dch #(j(k))will be a #(k) #(k - floor(Nrb/Nd)). Here, floor(Nrb/Nd) represents the interval between blocks RB, which posted one channel Dch.

Because here Nrb=12 and Nd=2, floor(Nrb/Nd)=6. Also, with regard to j(k), for k=1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 get j(k)=1, 5, 9, 2, 6, 10, 3, 7, 11, 4, 8, 12, as shown in Fig. 24. Thus, when k ≤ 6, Dch #(j(k)) is distributed across two blocks RB, RB #(k) and RB #(k+6)divided the s interval of 6 (=floor(12/2)) block RB in the frequency domain, and when k>6, Dch #(j(k)) is distributed across two blocks RB, RB #(k) and RB #(k-6), separated by an interval of 6 blocks RB in the frequency domain.

In particular, when k=1, j(k)=1 and therefore, Dch #1 posted by distributing in RB #1 and RB #7 (=1+6), and if k=2, then j(k)=5, and therefore, Dch #5 posted by distributing in RB #2, RB #8 (=2+6). The above explanation can be used when k=c 3 through 6.

Also, if k=7, then j(k)=3 and therefore, Dch #3 posted by distributing in RB #7 and RB #1 (=7-6)and, if k=8, j(k)=7, and therefore, Dch #7 posted by distributing in RB #8 and RB #2 (=8-6). The above explanation can be used when k=c 9 through 12.

Thus, as shown in Fig. 11, the channel Dch #1 and #3 are placed in the block RB #1 (RB #7), Dch channels #5 and #7 are placed in the block RB #2 (RB #8), the channel Dch #9 and #11 are placed in the block RB #3 (RB #9), Dch channels #2 and #4 are placed in the block RB #4 (RB #10), Dch channels #6 and #8 are placed in the block RB #5 (RB #11) and the channel Dch #10 and #12 are placed in the block RB #6 (RB #12) in the same manner as in method 3 placement for option 1. That is, the Dch channels with consecutive channel numbers are placed in different blocks RB, and the Dch channels with channel numbers within a predetermined number (here it is 2) are placed in one block RB. Thus, it is possible to obtain the same effect as in method 3 placement for option 1, when the number of Dch channels alternating with using block will peremesite what I it is shown in Fig. 24.

Here, as shown in Fig. 11, in the same blocks RB posted by channel numbers j(k)=1, 5, 9, 2, 6 and 10 of the first half of the output of the block interleaver shown in Fig. 24 (that is, the first and second columns of the block interleaver), and channel numbers j(k)=3, 7, 11, 4, 8 and 12 from the second half of the output of the block interleaver shown in Fig. 24 (i.e. the third and fourth columns of the block interleaver). That is, the channel number located on one and the same place in the first half (3 rows × 2 columns) block interleaver shown in Fig. 24 and containing the first and second columns, and in the second half (3 rows × 2 columns) block interleaver shown in Fig. 24 and containing the third and fourth columns have matching from the point of view of accommodation in the same blocks RB. For example, channel number 1, located in the first column of the first row of the first half (the first column of the first row of the block interleaver shown in Fig. 24), and channel number 3, located in the first column of the first row of the second half (the third column of the first row of the block interleaver shown in Fig. 24)placed in the same blocks RB (RB #1 and #7, as shown in Fig. 11). Similarly, channel number 5, located in the first column of the second row of the first half (the first column of the WTO is th row block interleaver, it is shown in Fig. 24), and channel number 7, located in the first column of the second row of the second half (the third column of the second row of block interleaver shown in Fig. 24)placed in the same blocks RB (RB #2 and #8, shown in Fig. 11). The above explanation can be applied to other positions.

In addition, channel numbers located in the same place in the first half and the second half of the output of the block interleaver, differ by an amount equal to (number of columns/Nd). Therefore, to make the number of columns of the block interleaver is equal to 4, as shown in Fig. 24, in the same RB will be posted by the Dch channels with channel numbers that differ from each other only in two rooms. That is, in one and the same block RB are the Dch channels with channel numbers within a predetermined number (the number of columns/Nd). In other words, it is possible to maintain the difference between the numbers of channels Dch placed in the same block RB, within a predetermined number by specifying the number of columns of the block interleaver is equal to (a predetermined number × Nd).

Next is described the method of allocation of channels for the case when the number of channels Dch (here it corresponds to the number of blocks Nrb RB) is not divisible by the number of columns of the block interleaver.

Below, this case is described with specific details. Put that Nrb=14, Nd=2, and the predetermined number is equal to 2. In addition, the channels Lch #1 to #14 or channels Dch #1 through #14 are formed using blocks RB. Since Nd=2, and a predetermined number is 2, the number of columns of the block interleaver is equal to 4. Thus, with regard to the dimension of the block interleaver, the number of columns is set to equal 4, and the number of rows is calculated as ceil(Nrb/number of columns), where the operator ceil(x) represents the minimum integer greater than X. That is, it uses a block interleaver of size 4 (=ceil(14/4)) rows × 4 columns, for example, as shown in Fig. 25.

If the dimension of the block interleaver shown in Fig. 25 is 16 (=4 rows × 4 columns), then the channel number k=1, 2,..., Nrb included in the block interleaver, does not exceed 14. That is, the number of Dch channels is less than the dimension of the block interleaver, the number of Dch channels (14) is not divisible by the number (4) column block interleaver. Thus, in this embodiment, the block interleaver is the number of zeros equal to the difference between the dimension of the block interleaver and the number of Dch channels. That is, in the block interleaver shown in Fig. 25, introduced two (=16-14) zero. In particular, two zeros are entered the same way in the last fourth line of the block is about the interleaver. In other words, two zeros are introduced at every second position in the fourth and final row of the block interleaver. That is, as shown in Fig. 25, zeros are entered in the second column and the fourth column of the fourth row in a block interleaver "4 rows × 4 columns". Thus, as shown in Fig. 25, the number k from 1 to 14 channels Dch are inserted in the direction of the columns at places other than those where there are zeros in the second column and the fourth column, the last of the fourth row. That is, in the last line of a block interleaver will say k=13, and 14 channels Dch in the column direction at each position where there are no zeros. When Nd=2, in each subblock of the two blocks RB post by distributing two different from each channel Dch, and therefore, the total number of Dch channels is an even number. Thus, the only possible such cases, when the number of zeros entered in a block interleaver with a number of columns equal to 4 0 or 2.

Because here Nrb=14 & Nd=2, floor(Nrb/Nd)=7. In addition, j(k) is a block interleaver "4 rows × 4 columns, as shown in Fig. 25. When performing output of the block interleaver zeros inserted into the block interleaver shown in Fig. 25, miss and do not display in the form j(k). That is, for k=1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 get j(k)=1, 5, 9, 13, 2, 6, 10, 3, 7, 11, 14, 4, 8, 12, as shown in Fig. 25. So the m way when k ≤ 7, Dch #(j(k)) post by distributing two blocks RB, RB #(k) and RB #(k+7), separated by intervals of 7 (=floor(14/2)) block RB in the frequency domain, and when k > 7, Dch #(j(k)) post by distributing two blocks RB, RB #(k) and RB #(k-7), separated by an interval of 7 blocks RB in the frequency domain.

In particular, if k=1, then j(k)=1 and therefore, Dch #1 post by distributing in RB #1 and RB #8 (=1+7), and when k=2, j(k)=5, and therefore, Dch #5 post by distributing in RB #2, RB #9 (=2+7). The above explanation can be used when k=c 3 through 7.

Also, when k=8, j(k)=3 and therefore, Dch #3 post by distributing in RB #8 and RB #1 (=8-7), and when k=9, j(k)=7, and therefore, Dch #7 post by distributing in RB #9 and RB #2 (=9-7). The above explanation can be used when k=c 10 to 14.

Thus, as shown in Fig. 26, the channel Dch #1 and #3 are placed in the block RB #1 (RB #8), Dch channels #5 and #7 are placed in the block RB #2 (RB #9), the channel Dch #9 and #11 are placed in the block RB #3 (RB #10), the channel Dch #13 and #14 are placed in the block RB #4 (RB #11), Dch channels #2 and #4 are placed in the block RB #5 (RB #12), the channel Dch #6 and #8 are placed in the block RB #6 (RB #13) and the channel Dch #10 and #12 are placed in the block RB #7 (RB #14). There are two channel Dch channel numbers within a predetermined number 2 place in all blocks RB, as shown in Fig. 26.

As in the case of a block interleaver shown in Fig. 24, in the same blocks RB posted by channel numbers j(k)=1, 5, 9 13, 2, 6 and 10 of the first half of the output of the block interleaver shown in Fig. 25 (that is, the first and second columns of the block interleaver), and channel numbers j(k)=3, 7, 11, 14, 4, 8 and 12 in the second half of the output of the block interleaver, (i.e. the third and fourth columns of the block interleaver, as shown in Fig. 26. Here one of the two zeros entered in the block interleaver shown in Fig. 25, introduced in the first half of the block interleaver "4 rows × 2 columns shown in Fig. 25 and containing the first and second columns, and the other two zeros are entered in the second half of the block interleaver "4 rows × 2 columns containing the third and fourth columns. Places entered in these two zeros are the second column of the fourth row of the first half of the output of the block interleaver (the second column of the fourth row block interleaver shown in Fig. 25) and the second column of the fourth row of the second half of the output of the block interleaver (the fourth column of the fourth row block interleaver shown in Fig. 25). That is, two zeros are entered in the same place in the first half and the second half of the block interleaver shown in Fig. 25. That is, two zeros are inserted in places that can be placed in the same block RB in a block interleaver. Thus, for the channel numbers Dch, put in place, great for the s from those places, where were entered zeros, it also supports compliance, resulting in the same block RB are channel numbers within a predetermined (number of columns/Nd). Therefore, in the same block RB are the Dch channels with channel numbers within a predetermined (number of columns/Nd), even if the number of Dch channels is less than the dimension of the block interleaver.

Next using Fig. 27 describes the processing sequence of the I/o block interleaver shown in Fig. 25. This is a fixed number of rows of the block interleaver is 4.

In step (hereinafter referred to as "ST") 101 the dimension of the block interleaver set in the form "(ceil(Nrb/4)) rows × 4 columns".

In step ST102 determine shares if the number (Nrb) blocks RB 4. Shown here in Fig. 27 the mod operator specifies the operator on module.

If at step ST102 is determined that the number (Nrb) blocks RB is divided into 4 (ST102: Yes), then in step ST103 in the block interleaver in the direction of the columns sequentially write the number (k) of Dch channels.

In step ST104 in the direction of the rows perform the reading rooms (j(k)) of Dch channels of the block interleaver.

On the other hand, if in step ST102 is determined that the number (Nrb) blocks RB is not divisible by 4 (ST102: No), then in step ST105 in blockymaterial in the direction of the columns sequentially write the number (k) of Dch channels, as this is done in step ST103. However, in any other column in the last row (for example, in the fourth line shown in Fig. 25) block interleaver enter zero.

At step 106 of the block interleaver in the direction of the rows in the same manner as in step ST104, perform serial numbers reading (j(k)) of Dch channels. However, non (j(k)) of Dch channels, which entered the zeros during recording in the block interleaver (for example, the second column and the fourth column of the fourth row, as shown in Fig. 25), miss.

Thus, if the number of Dch channels is not divisible by the number of columns of the block interleaver, while writing in a block interleaver of rooms k channels Dch recording is performed with the input of all zeros, and during the output of the block interleaver numbers (k) of Dch channels the reading is performed by omitting the zeroes. Because of this, even if the number of channels Lch is not divisible by the number of columns of the block interleaver, the Dch channels with consecutive channel numbers can be placed in different blocks RB, and the Dch channels with channel numbers within a predetermined number can be accommodated in one unit RB, as in method 3 placement for option 1.

In base station 100 and mobile station 200 channels Dch with consecutive channel numbers are placed in different blocks RB using isopycnal distribution channels Dch, moreover, pre-establish a pairwise mapping blocks RB, in which the Dch channels with channel numbers within a predetermined placed in the same block RB. That is, the allocation section 103 in the base station 100 (Fig. 1) and section 207 reverse display in the mobile station 200 (Fig. 2) support the layout of Dch channels shown in Fig. 26, which connects the blocks RB with Dch channels.

Then in the same way as in method 3 placement for option 1, section 103 allocation in the base station 100 allocates Dch data symbol blocks for RB in accordance with the scheme of allocation of channels Dch shown in Fig. 26. On the other hand, section 207 reverse display in mobile station 200, following the procedure similar to the one performed by the allocation section 103 extracts the character data Dch addressed to this station, from multiple blocks RB in accordance with the scheme of allocation of channels Dch shown in Fig. 26.

Thus, in the same way as in method 3 placement for option 1, with a small number of Dch channels used for a Dch data symbol of one mobile station, it is possible to obtain the frequency diversity effect, although there is a probability that the subunits other than the sub-blocks allocated in blocks RB will not be used. In addition, even if the number of Dch channels used for a Dch data symbol of one mobile is the first station is large (that is, when a large number of the allocated blocks RB), you can use all the subunits in blocks RB when the effect of frequency diversity.

Thus, in this embodiment, due to the alternation of channel numbers Dch, Dch channels with consecutive channel numbers are placed in different blocks RB, and the Dch channels with channel numbers within a predetermined number are placed in the same block RB. Due to this, in the same way as in method 3 placement for option 1, you can enhance the effect of frequency diversity with a small number of Dch channels used for a Dch data symbol of one mobile station. In addition, even if the number of Dch channels used for a Dch data symbol of one mobile station, great, you can enhance the effect of frequency diversity without compromising the efficient use of communication resources.

In addition, in this embodiment, even if the number of channels Dch and the dimension of the block interleaver are not consistent with each other and the number of Dch channels is not divisible by the number of columns of the block interleaver, the Dch channels with consecutive channel numbers, you can knead in different blocks RB, and the Dch channels with channel numbers within a predetermined number can be placed in one block RB by introducing zeros in the block interleaver. Furthermore, according to this is the option you same configuration block interleaver (i.e. the same distribution channels) to be used in systems with different number of channels Dch simply by introducing zeros in the block interleaver.

In this embodiment, there was described a case where the number (Nrb) blocks RB is an even number (for example, Nrb=14). However, a similar effect in this version, you can also get an odd number (Nrb) blocks RB by replacing Nrb maximum even number not exceeding Nrb.

Also in this embodiment, there was described a case where the places where you will put the two zeros are the second column of the fourth row of the first half of the output of the block interleaver (the second column of the fourth row block interleaver shown in Fig. 25) and the fourth column of the fourth row of the second half of the output of the block interleaver (the fourth column of the fourth row block interleaver shown in Fig. 25). However, in the present invention it is only necessary that the place where you will put the two zeros were the same in the first half and the second half of the output of the block interleaver. For example, in places where you will put the two zeros can be the first column of the fourth row of the first half of the output of the block interleaver (the first column of the fourth row block interleaver shown in Fig. 25) and the first column of the fourth row of the second half of the output of the block interleaver (the third column of the fourth row block interleaver shown in Fig. 25). In addition, places where you will put the two zeroes are not limited to the last row in lichnogo the interleaver (e.g., the fourth line shown in Fig. 25), and the zeros can be entered in the next line (for example, the first, second, or third line shown in Fig. 2).

This description of the variants of the present invention ends.

In the above embodiments, the positioning of the channels through which place the Dch channels in units of RB depends on the total number (Nrb) blocks RB defined by the width of the system bandwidth. Thus, for the base station and the mobile station can be provided to support the lookup of the number of Dch channels/number of blocks RB (for example, as shown in Fig. 4, Fig. 8, Fig. 11, Fig. 15 or Fig. 26) for each width of the system frequency band, and during the selection of the Dch data symbol can be accomplished by accessing the lookup table in accordance with the width of the system band, which is allocated a Dch data symbol.

In the above embodiments, the signal received by the base station (i.e., the signal transmitted by the mobile station for uplink communication), was described as a signal according to the OFDM scheme, but this signal can also be transmitted according to the transmission scheme, other than the OFDM scheme, for example, a scheme with one carrier or CDMA scheme.

In the above embodiments has been described a case where the block RB contains a number of subcarriers forming an OFDM symbol, but now from Britanie this is not limited to, and it is only necessary that the block contained a sequence of frequency.

In the above embodiments has been described a case where the blocks RB are consistently located in the frequency domain, but the blocks RB can also consistently be placed in a temporary area.

In the above embodiments were described with respect to the signal transmitted by the base station (that is, the signals transmitted from the base station on the downlink), but the present invention can also be applied to the signal received by the base station (i.e. the signal from the mobile station for uplink communication). In this case, the base station performs adaptive control allocation blocks RB, etc. for signal uplink connection.

In the above embodiments, adaptive modulation is performed only for channel Lch, but adaptive modulation can also similarly be performed for channel Dch. At the same time, the base station can perform adaptive modulation for Dch data based on the obtained and averaged over the entire band quality information transmitted from each mobile station.

In the above embodiments, the block RB used for channel Dch, is divided into many sub-blocks in the time domain, but the block RB used for channel Dch, also can be divided into many sub-blocks in the frequency the area or it can be divided into many sub-blocks in the interim, and in frequency domains. That is, in the same block RB plenty of Dch channels can be multiplexed in the frequency domain, or may be multiplexed in the frequency and time domains.

In these embodiments, there was described the case where the selection of one mobile station many different channels Dch with consecutive channel numbers, the base station instructs the mobile station, only the first channel number and last channel number, but the base station may, for example, to specify the mobile station, the first channel number and number of channels.

In these variants has been described a case where one channel Dch placed in blocks RB, which are available through distribution in the frequency domain with equal intervals, but one channel Dch is not necessary to place blocks RB, which are available through distribution in the frequency domain with equal intervals.

In the above embodiments, the channel Dch was used as a channel to perform transmission with frequency diversity, but used for this channel is not limited to the channel Dch, and it is only necessary that it was the channel, hosted by distribution in the frequency domain for many blocks RB or multiple subcarriers, which allows to obtain the frequency diversity effect. Also as a channel to perform transmission with chaston the m planning was used channel Lch, but used for this channel is not limited to the channel Lch, and it is only necessary that it was a channel that allows you to obtain the effect of multiuser diversity.

Channel Dch is also referred to as an allocated block of virtual resources (DVRB), and the channel Lch is also called localized block of virtual resources (LVRB). In addition, the block RB used for channel Dch, also referred to as a distributed physical resource block (DRB or DPRB), and the block RB used for channel Lch, also referred to as a localized block of physical resources.

The mobile station also referred to as user equipment (UE), the base station device called a node, and subcarriers is called a beep sounds. Block RB is also referred to as a subchannel, a block of subcarriers of the group of subcarriers, subpolicy or portion. The prefix CF also called a protection interval (GI). Subcat also called a slot or frame.

In the above embodiments, the example has been described a case where the present invention is configured in the form of hardware, but the present invention can also be implemented by means of software.

The functional blocks used in the description of the above options, usually implemented as LSI (LSI), which is a large integrated circuit. They can be implemented as a separate mi is rashami, either partially or fully contained in a single chip. This is a reduction of "LSI", but it also can be called as "IC" (integrated circuit), system LSI (system LSI), "super LSI" (scheme ultrahigh degree of integration), "ultra LSI" (scheme ultra-high degree of integration), depending on the varying degrees of integration.

The method of circuit integration is not limited to LSI circuits, it is also possible to implement using specialized circuits or General-purpose processors. Also after manufacturing LSI possible use of gate arrays, user-programmable (FPGA), or a reconfigurable processor where there is a possibility of reconfiguring connections and settings of circuit cells in the LSI.

If the result of the development of semiconductor technology or other related technologies introduced a new technology of integrated circuits will lead to replacement of the LSI, it is also possible to implement the specified function blocks in the integrated design, using this new technology. It is also possible the use of biotechnology.
