The technical field to which the invention relates.

The present invention relates to a transmitting device, receiving device, communication system and method of controlling the signal transmission.

The level of technology

Currently developing a way of fourth generation mobile communication (4G), representing the next generation standard IMT-2000 (International Mobile Telecommunications 2000). It is assumed that the method of the fourth generation (4G) will provide flexible support for a variety of environments, from mnogolistovyh environments, including cellular systems, to the environment of the isolated cells, such as the coverage area of the access point and the area inside the premises, and will increase the efficiency of use of frequencies in both types of cell environments.

The following methods access using radio communications have been proposed in the communication methods of the fourth generation to ensure the connection of the mobile station with the base station (hereinafter denoted by the term "upward connection"). As ways to transfer from one carrier have been proposed, for example, the way DS-CDMA (Direct Sequence Code Division Multiple Access, multiple access, code division channels and a direct extension of the spectrum), the way IFDMA (Interleaved Frequency Division Multiple Access, multiple access with split channels with the frequency of alternation) and the way VSCRF-CDMA (Variable Spreading and Chip Repetition Factors-CDMA, CDMA with variable CoE is ficiently expanding the range and repetition of elementary signals). As modes of transmission, with plenty of supporting methods have been proposed OFDM (Orthogonal Frequency Division Multiplexing, orthogonal multiplexing frequency division), Spread OFDM (OFDM expanded range), MC-CDMA (Multi-Carrier Code Division Multiple Access, multiple access, code division, and many of bearing) and VSF-Spread OFDM (Variable Spreading Factor Spread OFDM - OFDM with expansion of the range with a variable coefficient of expansion).

How to transfer from one carrier offers high performance, because peak power in them below from the viewpoint of the power consumption of the terminal, which reduces the time interval before re-transmission power amplifier of the transmission after a failed attempt.

As an example of the way with one bearing the following is a description of how VSCRF-CDMA with reference to figure 1 (see patent document 1).

Module 1 expansion range includes module 2 multiplied by the code module 8 multiple synthesis, coupled with module 2 of the multiplication by the code, and the module 10 phase shift, coupled with module 8 multiple synthesis.

Module 2 multiplied by the code multiplies the transmitted signal at the extension code. For example, the multiplier 4 multiplies the transmitted signal on channel code defined in accordance with a predetermined code rate SF expansion. In addition, the multiplier 6 multiplies the transmitted signal is l scrambling code.

Module 8 multiple synthesis compresses the signal spread spectrum time and performs the repetition of an elementary signal a predetermined number of times (CRF times). The transmitted signal, which was applied operation repetition, has a comb-shaped frequency spectrum. If the number of repetitions is equal to one, the module 8 multiple synthesis has the same configuration and performs the same functions as in the conventional DS-CDMA.

Module 10 phase shift rejects (or shifts) the phase of the transmitted signal with a predetermined frequency, the value of which is individually determined for each mobile station.

If the way VSCRF-CDMA CRF value greater than 1, for example equal to 4, the comb-shaped spectrum used by each user, are distributed over the whole frequency band, as shown in figa. In this case, is defined for each user of the frequency shift is less than the allocated bandwidth.

On the other hand, if the CRF value is 1, the spectrum used by each user, is located in the same block, as shown in figv. In this case, is defined for each user, the frequency shift is larger than the allocated bandwidth.

In addition, it was proposed access method using radio communications, in which receive the comb-shaped frequency spectrum in the frequency domain (SinePattern documents 1, 2).

As shown in figure 3, the transmitting device 30, which is accessed using the radio module contains 12 FFT (fast Fourier transform), which introduces a sequence of data spread spectrum module 14 conversion speed transmission coupled to the FFT module 12 module 16 a signal in the frequency domain, coupled to the conversion module 14 speed transmission, the inverse FFT module 18 connected to the module 16 a signal in the frequency domain, the module 20 add protection intervals, coupled with inverse FFT module 18, and the filter 22 connected to the module 20 add protection intervals.

Module 12 fast Fourier transform (FFT) divides every Q elementary signal data sequence spread spectrum into blocks and performs a fast Fourier transform, translating, thus, blocks in the frequency domain. As a result, in the frequency domain are obtained Q signals with a single carrier. Thus, the sequence spread spectrum corresponds to the output signal of the multiplier 6 module 1 expansion of the range of figure 1.

Module 14 conversion speed transmission repeats Q signals with the same carrier a predetermined number of times, such as CRF times. As a result, the number of generated signals from the one chosen to replace is equal to N sub=Q×CRF.

Module 16 a signal in the frequency domain shifts each of the signals with the same carrier on the frequency axis so that the spectrum acquires a comb-like shape. For example, if the operation corresponding CRF=4, between each of the signals with the same carrier insert three zero. The result is a comb-shaped frequency spectrum described with reference to figa and 2B.

The inverse FFT module 18 carries out inverse fast Fourier transform of a comb-like spectrum, resulting in a shift of each of the signals with the same carrier along the frequency axis.

Module 20 add protection intervals adds dedicated to the transmission of the signal protective intervals. Protective intervals are obtained by playing the top or end of each transmitted symbol. The filter 22 performs the limitation of the bandwidth of the transmitted signal.

On the other hand, the way many of bearing which use characters long, can provide a higher quality of reception in a multipath environment through the use of protective intervals.

In the example below with reference to figure 4 describes the OFDM method.

Figure 4 shows the block diagram of the transmitter module used in the transmitting device of the OFDM method.

The transmitting module 40 contains module 3 series-parallel (S/P) conversion, module 34 allocation of subcarriers connected to the module 32 S/P transform, inverse FFT module 36 connected to the module 34 allocation of subcarriers and the module 38 add protection intervals, coupled with module 36 inverse FFT.

Module 32 serial-to-parallel (S/P) conversion converts a serial signal sequence into a parallel signal sequence.

Module 34 distribution assigns subcarriers, each subcarrier signal converted in the module 32 series-parallel conversion in a parallel sequence. For example, the module 34 distribution assigns subcarriers separate subcarriers to each user, as shown in figa, to achieve frequency diversity. In addition, as shown in figv module 34 distribution assigns subcarriers to each user of consecutive subcarriers located.

The inverse FFT module 36 performs inverse fast Fourier transform of the input signal to provide a modulated according to the OFDM method.

Module 38 add protection intervals adds dedicated to the transmission of the signal protective intervals and generates a symbol of the OFDM method.

However, the above known from the prior art solutions have the following disadvantages.

Methods using a single carrier by deterioration in the reception quality caused by multipath interference, especially in cases where signals are transmitted at high speed due to short symbols.

Furthermore, the method using multiple frequencies require a larger time interval before re-transmission after a failed attempt, because the peak power becomes large relative to the power consumed by the terminal, has a problem of lower efficiency of energy use.

The implementation of the invention

Optimal the option of carrying out the invention is described below with reference to the accompanying drawings on the basis of the following examples.

In all drawings provided to illustrate the examples, parts or components that perform similar functions are denoted by the same numbers, and overly repetitive descriptions are omitted.

The mobile communication system according to one of the embodiments of the present invention includes a mobile station and a base station capable of radio communication with the mobile station.

Below is a description of the transmitting device in accordance with one embodiments of the present invention.

The transmitting device provided, for example, in the mobile station, transmits upstream channel.

The transmitting device according to this variant embodiment of the invention is used in cellular systems and in systems of local connection.

As shown in figa, the cellular communication system includes a base station covering individual cells (sectors), for example, the base station 2001, 2002, 2003, 2004and 2006and the mobile station 300 is capable of exchanging information with the base station 2001the radio channels. The cellular system has a larger radius of hundred or more high power mobile stations than local communication. However, the achievable data rate in the cellular system below in connection with the interference of the cross border cells.

Therefore, the application of the method with the same carrier as the method of radio communication in a cellular communication system has advantages compared with the use of the method with many carriers.

On the other hand, the local communication system, for example, operating within the same building or representing a communication system, a wireless access point contains a base station covering a single cell (sector), for example, the base station 2006and the mobile station 300 is capable of exchanging information with the base station 2006the radio channels. The local communication system has a smaller radius of the cell and lower the power consumption of the mobile station than the cellular system. However, the achievable data rate in the system link-local is relatively higher.

Therefore, the application of the method with many bearing as way radio communications in the local communication system has advantages compared with the use of the method with one carrier.

Next, with reference to Fig.7 described transmitting device in accordance with this embodiment of the invention.

The transmitting device 100 includes a module 102 diversity and channel coding, in which enter a sequence of characters, the switching module 106 connected to the module 102 extension spec is RA and channel coding, the module 108 fast Fourier transform (FFT) and the module 110 series-parallel (S/P) conversion connected with the switching module 106, and the module 112 conversion speed transmission coupled to the FFT module 108 and the module 110 S/P conversion.

In addition, the transmitting device 100 according to this variant embodiment of the invention contains the module 114 of the signal in the frequency domain, coupled with module 112 conversion speed transmission module 116 inverse FFT connected to the module 114 of the signal in the frequency domain, the module 118 add protection intervals, coupled with module 116 inverse FFT, and the filter 120 connected to the module 118 add protection intervals.

In addition, the transmitting device 100 according to this variant embodiment of the invention contains the module 104 controls the modulation data/degree of spread spectrum/channel coding, coupled with the module 102 expanding the range and channel coding and module 114 of the signal in the frequency domain, and the module 122 controls the allocation of radio resources, coupled with module 114 of the signal in the frequency domain. The switching module 106 is connected to the filter 120.

In module 104 controls the modulation data/degree of spread spectrum/channel coding type in the information is the modulation scheme and coding (Modulation and Coding Scheme, MCS) for each user. In module 122 controls the radio resource allocation type in the information notice on the allocation of radio resources for each physical channel and information on the planning results for each user.

The module 104 controls the modulation data/degree of spread spectrum/channel coding determines the degree of expansion of the spectrum of the orthogonal codes used in the module 102 diversity and channel coding, and outputs the orthogonal codes of a certain degree of expansion of the spectrum and the scrambling code for the cell and the MCS information for each user, the module 102 expanding the range and channel coding.

For example, in the cellular system module 104 controls the modulation data/degree of spread spectrum/channel coding determines the orthogonal code for the degree of spread spectrum corresponding to the given cellular system, and a scrambling code for the cell. On the other hand, in the system of local communication module 104 controls the modulation data/degree of spread spectrum/channel coding determines the orthogonal code for the degree of spread spectrum corresponding to the local communication system, and a scrambling code for the cell. In addition, the module 104 controls the modulation data is/degree of spread spectrum/channel coding passes the number of sets of subcarriers module 114 of the signal in the frequency domain.

The module 102 expanding the range and performs channel coding channel coding by applying an error correction code, for example, a turbo code or a convolution code, to the input sequence of binary information in accordance with the input information MCS and, thus, modulates the data is subjected to channel coding. In addition, the module 102 expanding the range and channel coding generates a sequence of elementary signals with spread spectrum by applying operations to extend the range using the input orthogonal codes and the scrambling code for the cell, and then outputs a sequence of elementary signals with spread spectrum in the switching module 106.

The switching module 106 determines whether the information received from the base station 200 and determines the type of radio communication method from one carrier or multiple carriers. If the switching module 106 determines that the received information on applicable way radio complies with the one way bearing, the switching module 106 transmits the entered sequence of elementary signals with spread spectrum module 108 FFT. If the switching module 106 determines that the received information on applicable way radio communications with the em method with many bearing, the switching module 106 transmits the entered sequence of elementary signals with spread spectrum module 110 S/P conversion. In addition, the switching module 106 transmits the received information on applicable way radio filter 120.

For example, the switching module 106 may determine the type of radio communication according to the notification from the base station 200. In this case, as shown in Fig, the base station 200 determines in module 402 determines how the radio (described below)whether the use by each user (mobile station) method with a single carrier or multiple carrier, and transmits the control information on the results of the determination of the applied method of radio communication mobile station 300.

In addition, the switching module 106 may determine whether a method with a single carrier or multiple carrier, for example, in accordance with the way radio set for each cell. In this case, the module 402 determines how the radio receiving device provided in the base station 200, determines in advance for each base station a permanent way upward Radiocommunication in accordance with the configuration of the cell.

For example, the module 402 determine how radio can determine the type of communication in set is VCE base station 200 in accordance with the configuration of the cell, for example, the radius of the cell, the presence or absence of neighboring cells and the like, for Example, if the cell radius is great, can apply the method with a single carrier, and if the cell radius is small is the way with many carriers. As shown in Fig.9, the module 402 determines how the radio transmits information about the applied method of radio communication mobile station 300 as common management information for all users.

In accordance with the foregoing, the type Radiocommunication determine when installing the base station, which leads to simplification of the configuration and management.

In addition, the switching module 106 may determine the type of radio (with one or many of bearing), for example, in accordance with the way radio set for each user (mobile station). In this case, it is possible to switch from one radio to another in accordance with the distance between each user and the base station or with a margin of transmission power for each user.

For example, if the type of communication change depending on the distance between each user and the base station 200, as a value which determines the distance between the user and the base station 200 may be used, for example, the amount of losses in the transmission path. In this case, the mob is supplemented flax station 300 measures the loss in the path of the downlink power taken downstream of the control signal and transmits the measured amount of losses in the transmission path of the base station 200 in the upward channel.

If the amount of losses in the transmission path more than a predefined threshold, the module 402 determines how the radio receiving device provided in the base station 200 determines that the distance between the base station 200 and the mobile station 300 is high, and determines the necessity of the application of the method of communication with one carrier. Then, as shown in figure 10, the module 402 determines how the radio notifies the mobile station 300 on the necessity of application of the method of communication with one carrier as a General control information addressed to a given user.

If the obtained value of losses in the transmission path is less than a predefined threshold, the module 402 determines how the radio receiving device provided in the base station 200 determines that the distance between the base station 200 and the mobile station 300 is small, and determines whether the application of the method of communication with a variety of carriers. Then, as shown in figure 10, the module 402 determines how the radio notifies the mobile station 300 on the necessity of application of the method of communication with a variety of bearing as a General control information addressed to a given user.

Thus, the applied way radio set is La each mobile station in accordance with the distance between the base station and the mobile station.

In addition, the mobile station can determine whether the application of the method of communication with one carrier or multiple carrier in accordance with the measured amount of losses in the transmission path and to report the result of the base station 200.

In addition, if switching from one communication method to another is carried out in accordance with the margin of transmission power of each user, the value which determines the stock of transmit power for each user can use, for example, the difference between the maximum transmission power and the current transmit power. In this case, each of the mobile stations transmits the base station is the difference between the maximum transmission power and the current transmit power.

If the difference between the maximum transmission power and the current transmit power is less than a predefined threshold, the module 402 determines how the radio receiving device provided in the base station 200 determines that the margin of transmission power is small, and determines whether the application of the method of communication with one carrier. Then, as shown in figure 10, the module 402 determines how the radio transmits to the mobile station 300 relevant information.

If the value of diff is STI between the maximum transmission power and the current transmit power level more than a predetermined threshold value, the module 402 determines how the radio receiving device provided in the base station 200 determines that the margin of transmission power is great, and determines whether the application of the method of communication with a variety of carriers. Then, as shown in figure 10, the module 402 determines how the radio notifies the mobile station 300 on the necessity of application of the method of communication with a variety of carriers.

In accordance with the foregoing, the control means of the radio communication is carried out in accordance with the performance of each of the mobile stations.

In addition, the mobile station 300 may transmit information on the maximum transmit power and the transmit power. In this case, the module 402 determines how the radio receiving device provided in the base station 200 may calculate the value of the difference between the maximum transmit power level and the current power transmission and install the applicable methods of radio communication in accordance with a calculated value.

In addition, the mobile station can determine whether the application of the method with a single carrier or multiple carrier in accordance with the stock power transfer and to report the result of the base station 200.

In addition, as shown in figure 11, the switching module 106 which may transmit a signal measurement channel status, for example, in the form of a control signal using a predetermined frequency band allocated by special request, in accordance with the method of radio communication, specific to each user (mobile station). For example, the switching module 106 may transmit a signal measurement channel status using only one frequency band allocated from the given system frequency bands. In particular, if the system given frequency band width, for example, 20 MHz, the mobile station (transmitting device) is distributed according to the classes of mobile stations that can use the band width of 20 MHz, 10 MHz and 5 MHz. In this case, the switching module 106 transmits a signal measurement channel status using only the frequency band corresponding to the given class of mobile stations (transmitting device), in accordance with the method of radio communication, is defined for a given user (mobile station).

Module 404 to determine a resource allocation of a radio receiving device 400 selects a mobile station (transmitting device), which transmit the measuring signal status channel bandwidth in accordance with the frequency band used for transmission of the measurement signal channel status.

In particular, each of the mobile stations (transmitting device) transmits a control signal, and BA the new station (receiving device) measures the control signals, and therefore, the channel state between the base station and mobile stations, thereby triggering the allocation of frequency bands. Mobile stations do not need to pass the control signals using the entire frequency band allocated to the system. Instead, the mobile station may transmit control signals using the predetermined frequency band. The base station receives the control signals from all users and allocates bandwidth, if the range of frequency bands has a bandwidth that can be allocated. Then the base station transmits information about certain bands transmitting devices.

In addition, the receiving device 400 may determine in module 420 determines how the radio frequency band used for transmission of the measurement signal channel status, and, thus, to provide information about the bands.

In addition, the switching module 106 may contain a module of generation of the control signal, which transmits the base station information of at least one of the following options: requested (maximum) bandwidth for transmission of the data channel, the amount of data to transfer, or data rate, in accordance with the communication method set for each user (mobile when Anzhi), if certain way radio represents a method with the same carrier. In addition, the module forming the control signal can convey information about the requested (maximum) bandwidth for transmission of the control signal of the base station.

For example, the module of generation of the control signal can transmit the base station information of at least one of the following options: requested (maximum) bandwidth for transmission of the control signal, the amount of data transfer or data transfer rate, channel, allocated on a competitive basis. For example, the maximum bandwidth is 5 MHz, and the requested bandwidth is less than 5 MHz.

As shown in figa, it is assumed that W_able - maximum bandwidth that can be used by the mobile station, Wp_req - requested maximum bandwidth for transmission of the control signal, a Wd_req - requested maximum bandwidth for transmission of the data channel. Module of generation of the control signal sets the value of the Wd_req within Wd_req≤W_able considering the size of the transmitted data and the data transfer rate. In addition, the module forming the control signal sets the value of the Wp_req within Wd_req≤Wp_eq≤W_able.

The switching module 106 may determine that the bandwidth for transmission of the measurement signal channel status equal to a whole multiple of the minimum bandwidth specified in the system, or twice the minimum bandwidth specified in the system.

In this case, the switching module 106 transmits, using the widest possible frequency band in which the expected value of the ratio of signal to interference and noise (SINR) receiving while transmitting with the maximum transmit power, or maximum capacity minus Δ" may be greater than the desired value of the SINR reception. For example, the switching module 106 may calculate the estimated SINR reception on the average interference power at the base station and the average loss in the transmission path between the base station (receiving device) and mobile station (transmitting device).

For example, if, as shown in figv, the maximum width of the transmission bandwidth is 5 MHz, and the minimum width of a transmission bandwidth equal to 1.25 MHz, the frequency bands of the transmission, equal to 1.25 MHz, 2.5 MHz and 3.75 MHz of bandwidth, providing the desired value of the SINR of the signal reception state measurement channel, equal to 1.25 MHz and 2.5 MHz. Therefore, the maximum bandwidth that provides the excess of the desired value of the SINR reception, equal to 2.5 M is C.

In this case, even if not expected to provide the desired value of the SINR reception in case of transmission using the minimum width of the transmission bandwidth used bandwidth of the transmission becomes the minimum width of the transmission bandwidth, and transmission is performed with the use of the minimum bandwidth transfer.

The desired value of the SINR of the signal reception state measurement channel spread on the broadcast channel across the cell.

In addition, the switching module 106 may be set to signal state measurement of channel quality requirements that differ from the quality requirements for the data channel, for example, in the form of the desired value SINR reception.

In this case, the base station device transmits information about the quality requirements for the broadcast channel to the mobile stations under the control of the sector. For example, the device is a base station may transmit information about the quality requirements of the data channel via a dedicated control channel.

The switching module 106 adjusts the transmit power in accordance with the requirements for signal quality measurement of the state of the channel when the channel data is not already highlighted. For example, the switching module 106 may perform transmission with the transmission power set regulation is coy transmission power in accordance with the quality requirements for transmission of the control signal. For example, the switching module 106 may set the lower limit of the required quality, a necessary and sufficient to measure the state of the channel, as shown in figs. This reduces interference with the control signals, which increases the throughput of the whole system.

The switching module 106 performs the adjustment of the transmission power for data and signal measurement channel status in accordance with the quality requirements of the data channel in the allocation of the data channel. For example, as shown in fig.12D, the switching module 106 may transmit with the same power as when transferring data, selecting the data channel. In this case, the higher the quality requirements set for data transmission, because they use a highly effective method of modulation and/or the degree of coding. The switching module 106 transmits the control signal with a higher transmit power, because it requires an accurate assessment of the status of the channel.

In particular, if the data channel is selected, and the bandwidth allocated to the data channel, narrower than the frequency band for signal transmission state measurement channel switching module 106 adjusts the transmit power of the signal measurement channel status to ensure compliance with the quality requirements for the data channel, for example, is the ratio of the magnitude of SINR reception in the frequency band for signal transmission measurement channel status, as shown in figa.

If the margin of transmission power is insufficient to ensure the required quality, the switching module 106 sets the maximum transmit power, as shown in fig.12F.

The base station 200 has a Central carrier frequency and bandwidth of the transmission (the width of the frequency band) of the control signal transmitted by the mobile station, the information transmitted by the mobile station, for example, requested (maximum) bandwidth, and reports information about a particular center frequency and information about a specific bandwidth control signal to the mobile stations.

Module of generation of the control signal transmits a control signal in accordance with the communicated information about the Central frequency and transmitted by the information bandwidth of the control signal. In addition, if you have been informed of the ID of the frequency block module of generation of the control signal transmits a control signal in accordance with a bandwidth and a center frequency defined by reported frequency ID block. In this case, the module of generation of the control signal can transmit the control signal using the method of frequency hopping. In addition, the module forming the control signal can before the VAT control signal by way frequency hopping, alternately using for transmission to each of the selected bands.

The module 108 FFT divides the data sequence spread spectrum blocks Q elementary signals, performs fast Fourier transform to convert the split sequence in the frequency domain, and outputs the converted split sequence in module 112 conversion speed transmission. As a result, in the frequency domain receive Q signals with a single carrier.

The module 110 series-parallel (S/P) conversion converts a sequence (stream) of signals in multiple parallel sequences of signals, and then outputs the parallel signal sequence in module 112 conversion rate.

Module 112 conversion speed transmission repeats Q signals with a single carrier, coming from the FFT module 108, a predetermined number of times, for example, equal to the ratio of the repetition of elementary signals (CRF). The number formed by signals on one carrier is equal to Nsub=Q×CRF. In addition, the module 112 conversion speed transmission outputs Q of the parallel sequences of signals received from the module 110 series-parallel (S/P) conversion module 114 of the signal in the frequency domain.

On the other the part, the module 122 controls the allocation of radio resources controls the time and frequency blocks allocated to each of the physical channels in accordance with the information on the allocation of resources to each of the physical channels, to inform the base station 200, and information about the results of the communication planning for each user.

In addition, the module 122 controls the allocation of radio resources determines the allocation of radio resources for a certain period based on the time scale of the duration of the time interval of the transmission Time Interval, TTI) frequency blocks, if the frequency blocks and the time allocated to each physical channel.

Next, with reference to Fig and 14 describes the planning of the use of multiplexed data channels. Multiplex data channels isolated in accordance with the scheduling performed in the base station 200, as described below.

Frequency blocks in accordance with the information management planning in the time domain when communicating with frequency multiplexing provided a stable allocation of frequencies, as shown in Fig. In this case, the user with high speed data transfer secrete multiple frequency blocks, which allows each user to use only the frequency blocks allocated in advance. Therefore clicks the zoom, the transmitting device 100 should not requested to transmit in other frequency blocks of the control signals transmitted to the receiving device 400 is able to perform the measurement quality indicator channel (Channel Quality Indicator, CQI).

For example, the optimal bandwidth for frequency block is from 1.25 to 5 MHz. The extension of the frequency band for frequency block may provide the strengthening effect explode multiple users within the frequency block.

When performing transmission with single-carrier bandwidth allocated to each user may vary in accordance with the speed of data transfer.

In addition, if the volume of the graph of any user exceeds the size of the payload frequency block, one of the frequency blocks may be used exclusively by one user.

Many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA within the frequency block. Namely, the spectrum used by each of the users have within the unit, as described with reference to figa and 2B. In addition, the comb-shaped frequency spectrum used by each user may be distributed across the frequency band. Other users are using the comb-shaped spectrum. Localise the bath FDMA method can basically be used in multiplex channels of data.

In addition, the same frequency band, for example, a frequency block may be allocated to multiple users, as shown in Fig. In this case, use frequency multiplexing using a comb-shaped frequency spectrum. Alternatively, perform the multiplexing of multiple users within the same frame, as described below. Information of elementary signals remain in a time transmission interval (TTI) with split time on some items. This information elementary signals is used as the element for changing the frequency used for transmission. As noted above, many users allocate a frequency band, and the transmission is performed with the use of frequency hopping. Highlighting some bandwidth to multiple users allows averaging of interference from other cells (sectors). Therefore, fluctuations of the interference from other cells (sectors) can be reduced compared to a situation in which to transmit replace users in a certain frequency band.

The following description is based on a situation in which the coverage area of the base station 200 comprises three sectors 2501, 2502, 2503; in the sector 2501meets the mobile station A300 1; and in the Gaza 2503there is a mobile station B3002mobile station C3003mobile station D3004and mobile station E3005for example, as shown in Fig.

If each user is allocated frequency blocks, if near a given mobile station in a neighboring sector, there is another mobile station, the interference power becomes higher, and if the other mobile station is at a greater distance, the interference power becomes lower.

For example, to the mobile station A3001available in sector 2501significantly affected by the interference from the mobile station D3004available in a neighbouring sector 2503located near the mobile station A3001but slightly affected by the interference from the mobile station E3005located at a great distance. Therefore, the interference power varies with time, as shown in figa.

On the other hand, when using frequency hopping and access with frequency multiplexing using a comb-shaped frequency spectrum of the interference power as a whole averaged and becomes essentially constant, as shown in figv that reduces fluctuations in the power of interference in time. In this case, although the power TRANS is giving each user below the effectiveness of communication for each user remains unchanged due to continuous selection of multiple time steps, which reduces fluctuations in the interference from other cells (sectors).

In addition, the frequency blocks can be allocated in accordance with the information management planning in the time domain and in the frequency domain, as shown in Fig.

In this case, the control channel which is passed to the measurement receiver 400 quality indicator channel (CQI), passed in all frequency blocks, i.e. all frequency bands of the channel.

In addition, if the volume of the graph of any user exceeds the size of the payload frequency block, one of the frequency blocks may be used exclusively by one user.

If there are many users with low data rate, multiple users share the same frequency block. In this case, the same frequency block used orthogonal frequency spectra, namely, the narrowed range of FDMA (localized FDMA method), distributed over the frequency block or comb-like spectrum (distributed way FDMA). In particular, as described with reference to figa and 2B, the spectrum used by each user, distributed in a unit within the frequency block. In addition to the, spectrum used by each user may be distributed and posted in the frequency block in the form of a comb, which reduces the mutual interference between users.

For example, the optimal bandwidth of the frequency block is 0,3125 to 1.25 MHz. By narrowing the bandwidth of the frequency block and scheduling channel in the frequency domain it is possible to achieve a stronger effect explode multiple users.

When performing transmission with single-carrier bandwidth allocated to each user may vary in accordance with the speed of data transfer.

Many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA within the frequency block.

Also, if planning to produce in the time domain and in frequency domain, frequency blocks can be grouped to reduce losses in the control channel.

In addition, as shown in Fig, the frequency range may vary depending on the channel status. For example, the frequency band allocated to the system, can be divided into a number of frequency blocks corresponding to this selection. In this case, when there is a good channel to produce multiple frequency blocks, for example, two frequency block (users a, b and C), and if x is dsem the channel to allocate a smaller number of frequency blocks, than when there is a good channel (user D). Transfer from one carrier is carried out in a dedicated thus the frequency band, which increases the overall efficiency of the system.

Below with reference to figa and 19C describes how the grouping of blocks.

As shown in figa if grouping blocks do not, many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA, within the frequency block or comb-like spectra.

As shown in figv, for grouping frequency blocks using the distributed grouping, in which the group form a discrete frequency blocks, or a localized grouping, in which the group form a series of frequency blocks.

As noted above, the losses in the control channel used for the measurement of CQI can be reduced through early grouping of frequency blocks to perform scheduling in the frequency domain.

For example, the module 404 to determine a resource allocation of a radio receiving device, provided in the base station 200 may determine the time and frequency allocated to the channel allocated on a competitive basis, for example, for a channel with random access or backup channel packages, depending on load and channel or other parameter, and reports the appropriate allocation of resources to each mobile station in a top-down broadcast channel. For example, the module 404 to determine the allocation of radio resources may determine the allocation of radio resources in such a way that, if the transmitted signal is a channel allocated on a competitive basis, in use, at least a portion of the allocated frequency bands.

In addition, the module 404 to determine a resource allocation of a radio receiving device, provided in the base station 200 performs scheduling according to the channel state and determines the time and frequency of the allocated channel, allocated on a competitive basis, for example, multiplexed data channel or the like, and notifies the appropriate allocation of resources to each mobile station in a top-down broadcast channel. The transferred data and control messages of the third level are transmitted in multiplexed data channel. In addition, the implementation of exchange of information on multiplexed data channel can be used hybrid automatic request retransmission (Hybrid Automatic Repeat Request (H-ARQ).

In addition, the module 404 to determine a resource allocation of a radio receiving device, provided in the base station 200 performs scheduling, determines the time and frequency of the allocated channel to be allocated on the basis of planning, such as the channel through to Oromo transfer control information (called multiplexed control channel), and reports the appropriate allocation of resources to each mobile station in a top-down broadcast channel.

The module 122 controls the allocation of radio resources provides multiplexing channel allocated on a competitive basis, and channel allocated on the basis of planning. For example, the module 122 controls the allocation of radio resources can provide temporary multiplexing channel allocated on a competitive basis, and channel allocated based planning, as shown in figa. In this case, the module 122 controls the allocation of radio resources can realize adaptive control parameter TTI and to set larger TTI, which reduces the share classes multiplexed control channel in the full duration of the TTI and reduces losses in the multiplexed control channel.

In addition, the module 122 controls the allocation of radio resources can provide frequency multiplexing channel allocated on a competitive basis, and channel allocated on the basis of planning, for example, as shown in figv.

In addition, the module 122 controls the allocation of radio resources can provide mixed using a time multiplexing and frequency multiplexing channel allocated on a competitive bases is, and channel allocated on the basis of planning. In this case, the module 122 controls the allocation of radio resources can realize adaptive control parameter TTI and to set larger TTI, which reduces the share classes multiplexed control channel in the full duration of the interval TTI and reduces losses in the multiplexed control channel.

Module 114 of the signal in the frequency domain shifts each of the signals with the same carrier along the frequency axis so that the spectrum becomes comb. For example, if the process corresponding to the value CRF=4, then for each signal or sequence with single-carrier signal is inserted by three zeros. In addition, the module 114 of the signal in the frequency domain allocates radio resources to each of the physical channels in accordance with information on the allocation of radio resources and, depending on the specific physical channel. If so apply the method with a single carrier, the CRF value and the offset value for each signal with a single carrier change, as well as the number of users.

Module 114 of the signal in the frequency domain provides the distribution for each of the Q parallel sequences of signals, directly includes each of the signal sequences is fishing in the frequency component, and allocates radio resources to each of the distributed signals.

Module 116 performs inverse FFT fast Fourier transform of a comb-like spectrum obtained by shifting each of the signals with the same carrier along the frequency axis, and, thus, forms a wavy spectrum transmission method with one carrier.

In addition, the module 116 inverse FFT performs inverse fast Fourier transform of a signal with many bearing consisting of a set of subcarriers, and performs modulation based on the OFDM method, forming, thus, the wave spectrum transmission method with multiple carriers.

Module 118 add protection intervals adds to intended for the transmission of signals protective intervals and generates a symbol of any of the OFDM method or way with many carriers. Protective intervals are obtained by repeating the initial or final stage of the transmitted symbol.

The filter shall limit the bandwidth of the transmitted signal. Then produce a signal with limited bandwidth.

Next, with reference to Fig describes the receiving device 400 according to this variant embodiment of the invention.

The receiving device 400 may be provided, for example, in the base station and to transmit the downward channel.

The receiving device 400 according to this variant embodiment of the invention used in isout in the above-mentioned cellular environment and the environment of the local area connection.

The receiving device 400 according to this variant embodiment of the invention is used to receive the signal transmitted from the application of the method with the same carrier and method with multiple carriers. In addition, the receiving device 400 includes a module 402 determines how the radio and module 404 to determine a resource allocation of the radio.

The module 402 determines how the radio determines authorized for use by the mobile station 300, the method of radio communication in accordance with the environment in which you are receiving device 400.

For example, in the case where the receiving device 400 is installed in the cellular environment, the module 402 determines how the radio determines the application of the method with one carrier and informs the mobile station 300 information on the application of the method with one carrier. If, for example, the receiving device 400 is installed in the environment of the local area communication module 402 determines how the radio determines the application of the method with many bearing and informs the mobile station 300 information on the application of the method with many carriers.

For example, when installing the base station 200 module 402 determines how the radio determines the type of radio communication in accordance with the configuration of the cell, for example, the radius of the cell, the presence or absence of neighboring cells and the like, for Example, if the cell radius is great to determine the application of the method with a single carrier, and if the cell radius is small, determine the application of the method with many carriers. The module 402 determines how the radio reports information about a particular to the use of the access method of the mobile stations 300 as common management information for all users.

Thus, the applied method Radiocommunication determine when installing the radio station that simplifies configuration and management.

In addition, it may be provided for switching from one radio to another depending on the distance between each user and the base station or the margin of transmission power of each user.

For example, if switching from one radio to another is carried out in dependence on the distance between each user and the base station 200, as a value corresponding to the distance between each user and the base station 200 may use the amount of losses in the transmission path. In this case, the mobile station 300 measures the amount of losses in the transmission path in the downward channel for receiving the power control signal in downlink and reports information about the results of measurements of losses in the transmission path of the base station 200 in the upward channel.

The module 402 determines how the radio determines that the distance between the gas station 200 and the mobile station 300 is large, if the resulting value of losses in the transmission path above a predefined threshold, determines whether the application of the method with one carrier and reports relevant information to the mobile stations 300.

The module 402 determines how the radio determines that the distance between the base station 200 and the mobile station 300 is small, if the resulting value of losses in the transmission path below a predefined threshold, determines whether the application of the method with many bearing and reports relevant information to the mobile stations 300 as common management information for all users.

Thus, for each mobile station establishes a method of radio communication in accordance with the distance between the base station and mobile stations.

In addition, if switching from one communication method to another is carried out in accordance with the margin of transmission power of each user, the value which determines the stock of transmit power for each user can use, for example, the difference between the maximum transmission power and the current transmit power. In this case, the mobile station informs the base station is the difference between the maximum transmit power and current is her power transfer.

If the difference between the maximum transmission power and the current transmit power is less than a predefined threshold, the module 402 determines how the radio sets that stock the transmission power is small, and determines whether the application of the method of communication with one bearing on what informs the mobile stations 300.

If the difference between the maximum transmission power and the current transmit power level more than a predetermined threshold value, the module 402 determines how the radio sets that supply power transfer is great, and determines whether the application of the method of communication with a lot of bearing on what informs the mobile stations 300.

In accordance with the foregoing, the way radio installed in accordance with the performance of each of the mobile stations.

In addition, the mobile station 300 may transmit information about the maximum transmission power and the current transmit power. In this case, the module 402 determine how radio can calculate the difference between the maximum transmission power and the current transmit power and to establish a method of radio communication in accordance with a calculated value.

Module 404 to determine the allocation of resources radiosvjaz what determines the allocation of radio resources for each of the physical channels and reports relevant information to the mobile station 300.

In addition, the module 404 to determine a resource allocation of the radio performs scheduling for each user and reports the results of such planning mobile station 300.

Module 404 to determine the radio resource allocation may allocate radio resources for some period of time based on the time scale of the duration of the time interval of the transmission Time Interval, TTI) frequency blocks, if the frequency blocks and the time allocated to each physical channel.

In addition, the module 404 to determine the radio resource allocation planning for multiplexed channel data.

Module 404 to determine the radio resource allocation planning access with frequency multiplexing in the time domain, and generates the control information, as shown in Fig. In this case, the user with high speed data transfer secrete multiple frequency blocks, allowing each user to only use pre-allocated frequency blocks. Therefore, the transmitting device 100 does not need to take control channel other transmitted frequency blocks, to ensure that the receiving device 400 can measure the quality indicator channel (CQI).

For example, the optimal bandwidth is often the nogo unit ranges from 1.25 to 5 MHz. Increasing the bandwidth of the frequency block allows you to enhance the effect of passing the multiple users in the frequency block.

When performing transmission with single-carrier bandwidth allocated to each user, may vary depending on the data transfer rate.

In addition, if the amount of traffic a user exceeds the size of the payload frequency block, one frequency block can be used exclusively by one user.

In addition, as shown in Fig, bandwidth may vary depending on the channel status.

Many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA within the frequency block. Namely, the spectrum used by each of the users have within the unit, as described with reference to figa and 2B. In addition, the comb-shaped frequency spectrum used by each user may be distributed across the frequency band. Other users are using the comb-shaped spectrum. Localized FDMA method can basically be used in the multiplex transmission channels.

In addition, the module 404 to determine the allocation of radio resources can plan access in the time domain and in the frequency region the tee and to generate control information.

In this case, the control channel transmitted to measure the quality indicator channel (CQI), passed in all frequency blocks, i.e. all frequency bands of the channel.

In addition, if the amount of traffic a user exceeds the size of the payload frequency block, one frequency block can be used exclusively by one user.

If there are many users with low data rate, multiple users share the same frequency block. In this case, the same frequency block used orthogonal frequency spectra, namely, the narrowed range of FDMA (localized FDMA method), distributed over the frequency block or comb-like spectrum (distributed way FDMA). In particular, as described with reference to figa and 2B, the spectrum used by each user, distributed in a unit within the frequency block. In addition, the spectrum used by each user may be distributed and posted in the frequency block in the form of a comb, which reduces the mutual interference between users.

For example, the optimal bandwidth of the frequency block is 0,3125 to 1.25 MHz. By narrowing the bandwidth of the frequency block and scheduling channel in the frequency domain it is possible to achieve a stronger effect explode m is Oresta users.

When performing transmission with single-carrier bandwidth allocated to each user may vary depending on the data transfer rate.

Many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA within the frequency block.

In this case, the frequency blocks can be grouped to reduce losses in the control channel.

In addition, the same frequency band, for example, a frequency block may be allocated to multiple users, as shown in Fig. In this case, use frequency multiplexing using a comb-shaped frequency spectrum. Alternatively, perform the multiplexing of multiple users within the same frame, as described below. Information of elementary signals remain in a time transmission interval (TTI) with split time on some items. This information elementary signals is used as the element for changing the frequency used for transmission. As noted above, many users allocate a frequency band, and the transmission is performed with the use of frequency hopping. Highlighting some bandwidth to multiple users allows sredneye interference from other cells (sectors). Therefore, fluctuations of the interference from other cells (sectors) can be reduced compared to a situation in which to transmit replace users in a certain frequency band.

Description grouping of frequency blocks is shown with links to figa and 19C.

If grouping blocks do not, many users with low data rate use the localized FDMA method, i.e. narrowed down version of FDMA, within the frequency block or comb-like spectra.

For grouping frequency blocks using the distributed grouping, in which the group form a discrete frequency blocks, or a localized grouping, in which the group form a series of frequency blocks.

As noted above, the losses in the control channel used for the measurement of CQI can be reduced through early grouping of frequency blocks to perform scheduling in the frequency domain.

For example, the module 404 to determine the allocation of radio resources may determine the time and frequency allocated to the channel allocated on a competitive basis, for example for channel with random access channel packet redundancy, depending on the load channel or other parameter, and reports the appropriate allocation of resources the owls each mobile station in a top-down broadcast channel. For example, the module 404 to determine the allocation of radio resources may determine the allocation of radio resources in such a way that, if the transmitted signal is a channel allocated on a competitive basis, in use, at least a portion of the allocated frequency bands.

In addition, the module 404 to determine the radio resource allocation planning in accordance with the state of the channel and determines the time and frequency of the allocated channel, allocated on a competitive basis, for example multiplexed data channel or the like, and notifies the appropriate allocation of resources to each mobile station in a top-down broadcast channel. The transferred data and control messages of the third level are transmitted in multiplexed channel data.

In addition, the module 404 to determine a resource allocation of a radio receiving device, provided in the base station 200 performs scheduling, determines the time and frequency of the allocated channel to be allocated on the basis of planning, such as the channel on which the transfer control information (called multiplexed control channel), and reports the appropriate allocation of resources to each mobile station in a top-down broadcast channel.

For example, module 04 determine the allocation of radio resources can be grouped channels in accordance with the state of the channels, for example, the measurement results of the CQI values for the implementation of resource allocation that minimizes the loss in the control channel.

In addition, the implementation of exchange of information on multiplexed data channel can be used hybrid automatic request retransmission (Hybrid Automatic Repeat Request (H-ARQ).

In addition, the module 404 to determine the radio resource allocation planning, determines the time and frequency allocated multiplexed control channel, and reports the appropriate allocation of resources to each mobile station in a top-down broadcast channel.

Below with reference to Fig describes the receiver, switching the frequency band depending on the channel status for the implementation of resource allocation.

The receiver 400 has the same configuration as the receiving device is described with reference to Fig.

Module 404 to determine a resource allocation of the radio receiver 400 includes a module 406 measuring the characteristics of the reception module 408 ranking connected with the module 406 measuring the characteristics of the reception module 410 allocation of frequency blocks, coupled with module 408 ranking module 412 determine the reception power, coupled with module 410 allocation of frequency blocks, and a module 414 determine the modulation scheme and codero the project (MCS), coupled with module 412 determine the reception power.

Module 406 measure performance measure some characteristics of the reception, such as the value of the SINR reception in each of the frequency blocks, for all users. All users transmit the control signals in the entire frequency band. Module 406 measuring performance determines the conditions for admission, for example the value of SINR receiving, for each of the frequency bands. In addition, if users use to send control signals to the part of the bandwidth total bandwidth (the bandwidth of the system), pre-define the size of the reception SINR for each unit of resource allocation in a given frequency band, for example, for each frequency block, as shown in figa. Namely, the module 406 measurement performance measures characteristics of the receiving transmitted control signals, using as a unit a predetermined unit of resource allocation of the frequency band.

If users are used for transmission of control signals some portion of the full bandwidth, the module 406 measurement of the reception characteristics can measure the conditions of admission to such portion of the frequency band, as shown in figv. Namely, the module 406 measurement performance measures characteristics of the receiving transmitted control signals using the as a unit to the desired unit of resource allocation, for example, the frequency of transmission of control signals.

Module 408 ranking sets priorities in accordance with the measured performance and ranking of priorities in a predetermined order, for example, to provide the highest possible value of the SINR reception for forming a table ranking. In addition, the module 408 ranking can generate a table ranking by at least one of the following options: conditions of reception of the control signal transmitted from each of the mobile stations, and reception conditions measured at the base station (in other words, the reception power measured by the receiver for measuring signal channel status), the waiting time and the type of data transferred from each of the mobile stations, and the maximum transmit power of each of the mobile stations. As a result, for each unit of allocation of frequencies to determine a mobile station, which allocate this bandwidth.

Module 410 allocation of frequency blocks allocates the frequency blocks in accordance with the ranking table. For example, the module 410 allocation of frequency blocks pre-selection of the frequency block for a user with high priority. In addition, the module 410 frequency allocation allocates blocks pre-allocated frequency BL is to and adjacent frequency blocks to the user with the highest priority. After this module 410 allocation of frequency blocks is a ranking of the priorities in descending order, excluding the priorities corresponding to the user and frequency blocks for which the selection is already made, re-ranks the table and repeats the same procedure. Thus, all devices emit a continuous frequency band in accordance with the reception characteristics of each transmitting device.

In this case, the module 410 allocation of frequency blocks allocates bandwidth within the frequency range of the transmission of the control signal, as shown in figa. This module 410 allocation of frequency blocks can allocate bandwidth on the units of selection or, for example, as an integer number of frequency bands, as shown in figv.

Further, if the mobile station transmits the control signals to all units in the allocation of frequency bands using frequency hopping, the module 410 allocation of frequency blocks can plan the frequency band in which the transmitted control signal, and to select the data channels, as shown in figa. In addition, the frequency band in which the transmitted control signal, emit, with the possibility of changes over time. In this case, the module 410 allocation of frequency blocks specifies the data channel for each frequency band, in which it was made transfers the control signal. In this case, the duration of the planning cycle is increased.

For example, at time t each mobile station, for example, MS1, MS2, MS3 and MS4 transmit the control signals in the same frequency band. Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals in the same frequency band. In this scenario planning exercise for the mobile stations MS1, MS2, MS3 and MS4, and allocate a data channel of the mobile station MS3.

At the time (t+1) mobile stations MS1, MS2, MS3 and MS4 transmit the control signals in the frequency bands that are different from those in which the transmission of the control signal was made at time t. For example, the mobile station MS1, MS2, MS3 and MS4 transmit the control signals in frequency bands adjacent to the frequency band in which transmission of the control signal was made at time t. Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals in the same frequency band. In this scenario planning exercise for the mobile stations MS1, MS2, MS3 and MS4, and allocate a data channel of the mobile station MS2.

At the time (t+2) mobile stations MS1, MS2, MS3 and MS4 transmit the control signals in the frequency bands that are different from those in which the transmission of the control signal was carried out at the time (t+1). Let the example the mobile station MS1, MS2, MS3 and MS4 transmit the control signals in frequency bands adjacent to the frequency band in which transmission of the control signal was carried out at the time (t+1). Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals in the same frequency band. In this scenario planning exercise for the mobile stations MS1, MS2, MS3 and MS4, and allocate a data channel of the mobile station MS2. After that, the procedure for allocation of data channel repeat.

If each of the mobile stations independently transmits a control signal using frequency hopping, the module 410 allocating the frequency blocks may plan for each unit of frequency allocation to mobile stations that transmit control signals in the respective frequency bands, and to allocate them to the data channel. For example, frequency and adjacent to the already selected frequency band may be allocated to a certain mobile station.

For example, suppose at time t the mobile station, for example, MS3, MS4, MS5 and MS6, transmit control signals in different frequency bands: the mobile station MS1 transmits the control signal in the same frequency band, in which transmit control signals to the mobile stations MS3 and MS4, and the mobile station MS2 transmits the control signal in the same frequency band, the which transmit control signals to the mobile station MS5 and MS6.

Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals in the respective frequency bands. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands. For example, the module 410 allocation of frequency blocks performs scheduling for the mobile stations MS1 and MS3, and allocates the data channel of the mobile station MS1; planning for mobile stations MS1 and MS4 and allocates the data channel of the mobile station MS4; planning for mobile stations MS2 and MS5 and allocates the data channel of the mobile station MS5; planning for mobile stations MS2 and MS6 and allocates the data channel of the mobile station MS2.

At the time (t+1) mobile station, for example, MS3, MS4, MS5 and MS6 transmit the control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was made at time t. In addition, mobile station, for example, MS1 and MS2 transmits control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was made at time t.

Module 410 allocation of frequency blocks carries out planning the Finance for mobile stations, transmitting the control signals in the respective frequency bands. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands. For example, the module 410 allocation of frequency blocks performs scheduling for the mobile stations MS2 and MS6 and allocates the data channel of the mobile station MS2; planning for mobile stations MS2 and MS3, and allocates the data channel of the mobile station MS2; planning for mobile stations MS1 and MS4 and allocates the data channel of the mobile station MS4; planning for mobile stations MS1 and MS5 and allocates the data channel of the mobile station MS5.

At the time (t+2) mobile station, for example, MS3, MS4, MS5 and MS6 transmit the control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was carried out at the time (t+1). In addition, mobile station, for example, MS1 and MS2 transmits control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was carried out at the time (t+1).

Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals to the corresponding floor is sakh frequencies. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands. For example, the module 410 allocation of frequency blocks performs scheduling for the mobile stations MS1 and MS5 and allocates the data channel of the mobile station MS5; planning for mobile stations MS1 and MS6 and allocates the data channel of the mobile station MS6; planning for mobile stations MS2 and MS3, and allocates the data channel of the mobile station MS2; planning for mobile stations MS2 and MS4, and allocates the data channel of the mobile station MS4.

Further, if each of the mobile stations independently transmits a control signal using frequency hopping, as shown in figs module 410 allocating the frequency blocks may allocate a data channel in each allocation unit of frequency bands, using as characteristics of the reception quality index admission) received in the past reception quality if you use a frequency band in which the control signals are not passed. In this case, the set of mobile stations can transmit control signals in the same frequency band.

For example, suppose at time t the mobile station, for example, MS1, MS2, MS3 and MS4 transmit the control signals in different frequency bands.

Module 410 allocation of frequency blocks shall schedule the W for mobile stations, transmitting the control signals in the respective frequency bands. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands.

At the time (t+1) mobile station, for example, MS1, MS2, MS3 and MS4 transmit the control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was made at time t.

Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals in the respective frequency bands. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands, using as characteristics of the reception quality index admission) received in the past reception quality if you use a frequency band in which the control signals are not passed in.

At the time (t+2) mobile station, for example, MS1, MS2, MS3 and MS4 transmit the control signals in different frequency bands. For example, the control signals transmit in frequency bands adjacent to the frequency band in which transmission of the control signal was carried out at the time (t+1).

Module 410 allocation of frequency blocks is responsible for planning for mobile stations that transmit control signals for the operating frequency bands. Module 410 allocation of frequency blocks performs scheduling for each unit of allocation of frequency bands, using as characteristics of the reception quality index admission) received in the past reception quality if you use a frequency band in which the control signals are not passed in.

If it is assumed the presence of small fluctuations in the channel status and the bandwidth in which to transmit the control signal is not changed, if the state of the channel in a given frequency band is getting worse, also deteriorate and characteristics of the reception frequency band. Therefore, changing the transmission bandwidth control signals may allow to improve the characteristics of the reception.

Next, as shown Fig, if the frequency band of the frequency allocation of a dedicated data channel, the allocated bandwidth does not change, while the reception conditions vary within certain limits. Namely, after the module 410 allocation of frequency blocks to allocate bandwidth module 410 allocation of frequency blocks is continuously doing the same frequency band, while the reception signal strength measurement channel status of this frequency band in the receiving device exceeds a predetermined threshold value. For example, if the channel state of the selected frequency band is changed more than a predetermined threshold the values, the band release and make a new selection based on the status of channels for each of the mobile stations. This reduces the interference from other cells (sectors). The receiver 400 modifies the applied modulation method in accordance with the conditions of admission before applying modulation and coding (AMC). Changes in conditions after determining the modulation method or other similar parameters hinders reception. Namely, the conditions of reception in uplink influenced by other cells (sectors), including other closely located users. For example, if the mobile station A3001transmits at a time, as the mobile station D3004located in the neighboring sector 2503on Fig, also transmits, to the mobile station A3001affected by the interference from the mobile station D3004.

If the mobile station A3001transmits at a time, as the mobile station B3002located in the neighboring sector 2503also transmits, to the mobile station A3001affected by the interference from the mobile station B3002. Mobile station A3001determines the modulation method in relation used radio waves to the radio wave interference. If the frequency band allocated to the mobile station B3002, transmit mobile station C3004the level of interference increases. Although mobile station A3001defines the sequence of modulation and coding (MCS) subject to interfering signals from the mobile station B3002when the sudden realization of the allocation of frequencies, which leads to the transmission bandwidth of the mobile station C3004the level of interference from the adjacent sectors increases, which does not allow the receiving station to receive using a predefined modulation method.

To avoid this situation, the allocated bandwidth may not be changed up until the change of the reception conditions do not exceed a certain level. If changing reception conditions exceed a certain level, for example a certain threshold value, the band released and make new selection based on the status of channels for each of the mobile stations.

Module 412 determine the reception power assigns the mobile station to which the allocated bandwidth, some transmit power in the uplink. In this case, some transmit power in the uplink is credited with the mobile station (transmitter), which allocated bandwidth in accordance with the selected frequency band. For example, the maximum power with which the mobile station(transmitter) can pass, known. The following describes the situation in which the transmission power allocated bandwidth is equal to, for example, X, as shown in figa. When extending the allocated frequency bands, for example, twice the transmit power is reduced by half and becomes equal to X/2, as shown in figv. Defining transmission power in a selected frequency band as follows. Module 412 determine the reception power passes the results to planning and information about the transmission power of the transmitter. This set of information is received in the module 122 controls the allocation of radio resources.

For example, if the transmission power of a certain selected frequency band has a maximum value equal to X, then the expansion of the allocated frequency bands, for example, twice the maximum value of the transmission power is reduced by half and becomes equal to X/2.

Module 412 determine the reception power passes the results to planning and information about the transmission power of the transmitter. This set of information is received in the module 122 controls the allocation of radio resources. In the mobile station transmits upstream channel with a maximum transmit power of the selected frequency band.

Above the concentration of power in a particular frequency band allows you to increase the power of ispolzuemyhperedovyh. In particular, if the concentration of power in some frequency band perform to enable transmission from the mobile station located at a great distance from the base station (receiving device), the base station can receive the signal with higher power, which improves the quality of reception.

Module 412 determine the reception power can measure the interference power in the allocated frequency band and to assign a transmit power given the power of the interference so that the ratio of the power used radio waves to power the interference corresponded to a predetermined value.

In this case, the power that provides the desired ratio of the power used radio waves to power the interference may be greater than or equal transmit power, which can provide the mobile station. In this case, assign the transmit power, which can provide the mobile station. If the same power which provides the desired ratio of the power used radio waves to the power of interference is less than or equal to the transmission power, which can provide a mobile station, there shall be a power, which provides the desired ratio of the power used radio waves to power interference.

Thus, the transmit power can be set in the accordance with the reception quality at the base station.

In addition, the mobile station transmits a signal in the uplink channel with the maximum capacity for the selected frequency band. The base station can signal a higher power, which improves the quality of reception.

In addition, from the point of view of the use of transmit power, the mobile station may transmit upstream channel with a constant power density, regardless of the width of the allocated frequency bands. For example, as shown in figa and 28V module 122 controls the allocation of radio resources may transmit with a certain transmit power in accordance with a predetermined bandwidth, even if the allocated bandwidth ý a predetermined frequency band. Since, as indicated above, transmission is performed with constant specific power of the transmission frequency band, interference with other cells (sectors) may have a smaller impact.

The transmit power can be changed depending on the position of the mobile station. Namely, it is possible to determine whether the transmission of upstream channel with a maximum transmit power for the selected frequency band or with a constant power density, regardless of the selected frequency band. In this case, you can determine the transmit power p and an appropriate way to define and communicate the information about the used transmit power.

The base station may assign the modulation method and the degree of code error correction in the transmission of upstream channel mobile station to which the allocated bandwidth.

The modulation method and the degree of error-correction code can be defined by the ratio of the power used radio waves to power the interference module 414 determine the modulation scheme and coding (MCS) of a base station. This may be instantaneous or average power used by the frequencies and levels of interference. For example, if the sending device to which the selected frequency band, transmits a signal in accordance with the designated transmission power and a reception power of the signal measurement channel status, a receiving device that receives the signal transmitted by the transmitting device, makes use of the instantaneous or average value in accordance with the reception power and interference power, and the reception power and interference power estimate for the selected frequency. Then regarding the reception power to the power of interference determines the modulation method and the degree of error-correction code.

Further, as an example describes a situation in which a mobile station transmits upstream channel with the maximum for the selected frequency band of the transmit power. ewnost interference in the uplink strongly fluctuates. When the modulation method is determined by the instantaneous value of the receiving power, the power level of interference varies depending on the time required to start the transfer. Therefore, when such transfers use the average value of the reception power used radio waves and interference.

Further, as an example describes a situation in which a mobile station transmits upstream channel with a constant power density, regardless of the width of the allocated frequency bands. When making adjustments in such a situation when small fluctuations of power interference using instantaneous reception power used radio waves and interference.

When the module 414 define MCS MCS assigns during transmission of the data channel of the mobile station that has permission to transmit, module 414 define MCS can assign MCS in accordance with the reception quality of the control signal, measured for each unit of allocation of frequencies in the selected frequency band, if the value of the reception SINR is measured for each unit of frequency allocation by module 406 measuring performance, as shown in Fig. For example, if you use the value of the reception SINR measured for each unit of frequency allocation, MCS appointed in accordance, m is Nisha least with one of the following values: average value of the SINR, the highest value and the lowest SINR SINR value.

In addition, the receiver selects to change the frequency band depending on the channel status, may have the configuration illustrated in Fig.

The receiver 400 has essentially the same configuration as the receiver described with reference to Fig, but differs from the receiver described with reference to Fig, because it provides a module 416 destination of the control signal, connected to module 406 measuring performance.

Module 416 destination of the control signal receives the information, at least one of the following types: information requested (maximum) bandwidth of the transmission channel of the data transmitted from the mobile station, information about the amount of transmitted data and information about data transfer speeds. In addition, the module 416 destination of the control signal receives information about the requested maximum bandwidth of the transmission control signal from the mobile station. Module 416 destination of the control signal designates the mobile station bandwidth for transmission of the control signal. For example, a module 416 destination of the control signal determines the width and the Central frequency of the transmission bandwidth control the on signal in accordance with the information requested (maximum) bandwidth of the transmission control signal for each mobile station, and transmits information about a specific width and Central frequency bands transmit frequencies of the control signal corresponding mobile stations. In addition, the module 416 destination of the control signal may provide information about a specific width and center frequency of the frequency bands of the transmission of the control signal corresponding transmitting device by passing the IDs of the frequency blocks. In this case, a module 416 destination of the control signal can assign multiple frequency blocks.

For example, a module 416 destination of the control signal designates the frequency band width which is smaller than the maximum bandwidth requested by the mobile station (requested (maximum) bandwidth), if it determines that the reception quality of the control signal is not high enough even in the case where the mobile station transmits a control signal using the requested (maximum) bandwidth due to the large distance to the base station. For example, a module 416 destination of the control signal designates the width of the frequency band in accordance with the maximum transmission power of each of the mobile stations and the level of losses in the transmission path between the base station and each of the mobile stations.

In addition, the module 416 destination of the control signal designates the width and the Central frequency of the transmission bandwidth of controllergeneral for each mobile station so that to ensure the reduction or absence of deviations of the reception power of the control signal, measured in the frequency domain, when assigning width and Central frequency of the transmission bandwidth control signal for each mobile station, as shown in Fig. For example, a module 416 destination of the control signal determines in advance a reference value of the variance of the reception power of each of the control signal and determines the width and the Central frequency of the transmission bandwidth of the control signal so that the deviation did not exceed this reference value. In this case, a module 416 destination of the control signal calculates reception power of the base station control signals from mobile stations in a rising channel and assigns the width and the Central frequency of the transmission bandwidth control signal for each of the mobile stations so as to reduce variation of the width of the transmission bandwidth in the frequency domain.

In addition, if the module 416 destination of the control signal allows mobile stations to transmit control signals using the method of IFDMA, module 416 destination of the control signal determines the bandwidth and rate of recurrence for control signal from each mobile station so that each frequency element was used for sovan without excessive or insufficient load, as shown in figa. Namely, on the basis of the method of frequency multiplexing determine the magnitude of the frequency shift and transfer. In this case, use the frequency shift of this magnitude, which allows you to delete multiple use of any stripe one and the same user. For example, a module 416 destination of the control signal designates the width and the Central frequency of the transmission bandwidth control signal for each of the mobile stations in accordance with the residual value of the coefficient of repetition. In this case, a module 416 destination of the control signal designates and reports the values of the repetition factor, bandwidth and center frequency of the bandwidth control signal.

In addition, the module 416 destination of the control signal designates the frequency band of the transmission signal of the measurement channel status so that the number of mobile stations that transmit signals to measure the state of the channel in each frequency band was not changed. For example, a module 416 destination of the control signal selects the frequency band of the transmission signal of the measurement channel status for each mobile station, since the mobile stations having the widest bandwidth transmission. In this case, the width of the transmission bandwidth is, for example, 2nthe minimum widths shall not transmit frequencies.

Below is a description example of a situation in which the system bandwidth is 10 MHz, the number of mobile stations with a bandwidth of 5 MHz 2.5 MHz 1.25 MHz, is equal to N5N2.5and N1.25. In this case, it is assumed that the minimum band width, such as width of the frequency block, equal to 1.25 MHz.

(1) Variables, f5MHzF2.5MHzand f1.25MHzassign random values. In this case, the random values are integers.

(2) Frequency unit ID and unit 4 (=5/1,25 unit from ((f5MHz+n5)mod(10/5)×(10/5)) allocate n5-th mobile station with the bandwidth of 5 MHz.

(3) the Frequency block ID 2 block (=2,5/1,25 unit from ((f5MHz+N5+n2.5)mod(10/5)×(10/5)+(f2.5MHz+n2.5)mod(5/2,5)×(5/2,5)) allocate n25-th mobile station with the bandwidth equal to 2.5 MHz.

(4) the Frequency block ID and 1 block (= 1,25/1,25 unit from ((f5MHz+N5+N2.5+n1.25)mod(10/5)×(10/5)+(f2.5MHz+N2.5+n1.25)mod(5/2,5)×(5/2,5)+(f1.25MHz+N2.5+n1.25)mod(2,5/1,25)×(2,5/1,25)) allocate n1.25-th mobile station with the bandwidth equal to 1.25 MHz.

For example, in the case of N5=3, N25=3, N1.25=4, f5MHzF2.5MHzand f1.25MHz=0 the allocation of frequency bands of the mobile stations in the sector is made one by one, starting with mobile the x stations with the wide bandwidth of the transmission, as shown in figv.

Module 416 destination of the control signal performs the above-described selection within a predetermined cycle, since the width of the transmission bandwidth and the number of mobile stations in the sector change due to losses in the transmission path caused by the movement of mobile stations and/or transmission of the connection.

If the mobile station transmits a control signal using the requested maximum bandwidth of the transmission module 406 measurement performance measures the value of the SINR reception using the requested bandwidth requested for the allocation of bandwidth) data channel as a unit, as shown in Fig.

Module 410 allocation of frequency blocks allocates bandwidth to each of the mobile stations within the transmission bandwidth control signal in accordance with measured data values SINR reception, information about the frequency band of transmission of the control signal and information about the requested bandwidth of the data channel. In this case, the module 410 allocation of frequency blocks can make a selection using one of the predefined unit selection frequency, such as frequency block.

Module 414 define MCS assigns a value to the MCS mobile station, where RA is solve the transfer, in accordance with the reception quality of the control signal in the selected frequency band, as shown in Fig.

Below with reference to Fig describes the operation of the transmitting device 100 according to the above-described variant embodiment of the invention.

The base station 200 identifies the way radio used by the mobile station 300, and reports the results of the identification method, the mobile station 300.

First carry out obtaining information about the way radio communication (step S1302).

Then the switching module 106 determines if information about how the radio on the way to single-carrier (step S1304).

If the information about how the radio indicates the method with single-carrier (step S1304: YES), the switching module 106 switches on the way with one carrier. Namely, the switching module 106 outputs the received sequence of elementary signals in the FFT module 108.

Then the module 114 of the signal in the frequency domain determines attributed to whether the data transfer to the channel allocated on a competitive basis (step S1308).

If the data transfer is attributed to the channel allocated on a competitive basis (step S1308: YES), the module 114 of the signal in the frequency domain allocates radio resources for a channel that is allocated on a competitive basis, in accordance with the received information is the s on the allocation of radio resources. Then transfer data, for which the allocated radio resources (step S1310).

If data transfer is not assigned to the channel allocated on a competitive basis (step S1308: NO), the module 114 of the signal in the frequency domain allocates radio resources for a channel that is allocated on the basis of planning, in accordance with the received information on the allocation of radio resources. Then transfer data, for which the allocated radio resources (step S1312).

If the information about how the radio indicates the way with many carriers (step S1304: NO), the switching module 106 switches on the way with many carriers. Namely, the switching module 106 outputs the received sequence of elementary signals in the module 110 series-parallel conversion (step S1314).

Then the module 114 of the signal in the frequency domain determines attributed to whether the data transfer to the channel allocated on a competitive basis (step S1316).

If the data transfer is attributed to the channel allocated on a competitive basis (step S1316: "YES"), the module 114 of the signal in the frequency domain allocates radio resources for a channel that is allocated on a competitive basis, in accordance with the received information on the allocation of radio resources. Then is carried out before the Chu data for which the allocated radio resources (step S1318).

If data transfer is not assigned to the channel allocated on a competitive basis (step S1316: "NO"), the module 114 of the signal in the frequency domain allocates radio resources for a channel that is allocated on the basis of planning, in accordance with the received information on the allocation of radio resources. Then transfer data, for which the allocated radio resources (step S1320).

Below with reference to Fig describes the operation of the receiving device 400 according to the above-described variant embodiment of the invention.

First module 402 determines how the radio determines which way radio uses the mobile station 300.

The following is a description of a situation in which the module 402 determines how the radio determines that the mobile station 300 uses way radio communications with one carrier.

Module 406 measurement performance measures priority in each of the frequency blocks, for example, the value of the reception SINR for all users (step S2602). Priority values corresponding to the number of frequency blocks, receive for each user.

Then the module 408 ranking ranks the priorities of type(number of users) × (the number of frequency blocks)in descending order and establishes the correspondence between the users of the frequency blocks, forming ranking table (step S2604).

If all users transmit control channels, using the whole bandwidth, the number of ranks in the ranking table is equal to the product of the number of users on the number of frequency blocks. If users transmit control channels using different frequency bands, the ranks, the corresponding frequency blocks in which the users do not transmit the control channels are missing. For example, if a user transmits a control channel using 5 frequency blocks of 8, then ranks the remaining 3 frequency blocks are not included in the ranking table.

Then the module 410 allocation of frequency blocks pre-allocation of frequency blocks each user in the queue according to the priority value (step S2606).

Module 410 allocation of frequency blocks uses the ranking table, and allocates the frequency blocks corresponding to the users with higher priority. For example, in accordance with the ranking table, user a has the rank of No. 1, and the user And corresponds to the frequency block 4. In this case, in the frequency block 4 make a record "A1"indicating the user a and the rank of No. 1. Similarly, the entry "A2", indicating that user a and grade No. 2, bring in frequency block 5. Through repetition of the same PR is the procedures to get a preliminary selection.

Then the module 410 allocation of frequency blocks selects contiguous frequency blocks selected from frequency blocks previously allocated to the user with the highest priority (step S2608).

The user And the selected frequency blocks 3-5 and frequency unit 8. However, in connection with the application of the method with one carrier carry out the allocation of the frequency band containing the frequency block with the highest priority. In other words, allocate frequency blocks 3-5.

Then the module 410 allocation of frequency blocks checks whether all the frequency blocks are allocated or all users allocated frequency blocks (step S2610).

If all the frequency blocks are allocated or all users allocated frequency blocks (step S2610: "YES"), then for all users, which allocated frequency blocks, determine the transmission power and the MCS value (step S2614).

If not all of the frequency blocks are allocated or not all users of the allocated frequency blocks (step S2610: "NO"), the module 410 allocation of frequency blocks is a ranking of priorities in accordance with their value, excluding the priorities of users who already allocated frequency blocks (step S2612), and then returns to step S2606.

In the above example, since the frequency 3-5 blocks were allocated to the user a, the above procedure is repeated, excluding the tea from her frequency blocks 3-5.

Thus, each of the users allocate bandwidth to ensure a good channel state. Each user emit not discrete, but continuous frequency blocks.

Next, with reference to Fig describes another receiving device 400 according to this variant embodiment of the invention. In particular, the description of the operation of the receiving device 400 described with reference to Fig. As described above, the receiving device 400 is provided in the base station, and the transmitting device 100 provides the mobile station.

First module 402 determines how the radio determines which way radio uses the mobile station 300.

The following is a description of a situation in which the module 402 determines how the radio determines that the mobile station 300 uses way radio communications with one carrier.

Module formation control channel transmits the mobile station information, at least one of the following types: information requested (maximum) width of the transmission bandwidth of the data channel to the base station, information about the amount of transmitted data, the information data rate. In addition, the module forming the control channel reports information about the requested maximum bandwidth PE is Adachi control signal (step S3802).

Module 416 destination of the control signal determines the width and the center frequency of the bandwidth control signal transmitted by the mobile station in accordance with information about the requested maximum bandwidth of the transmission control signal (step S3804), and informs the mobile station information about a specific width and center frequency of the bandwidth control signal (step S3806). In addition, the module 416 destination of the control signal may provide information about a specific width and center frequency of the bandwidth control signal corresponding transmitting device by passing the ID of the frequency block. In this case, a module 416 destination of the control signal can assign multiple frequency blocks. For example, a module 416 destination of the control signal can assign bandwidth in accordance with the maximum transmission power of each mobile station and the level of losses in the transmission path between the base station and each of the mobile stations.

Module formation control channel transmits a control signal in accordance with the communicated information about the width and the center frequency of the frequency band (step S3808). In this case, the module forming the control channel can transmit a control signal by way of abrupt perest the ISP frequency.

Module 406 measurement performance measures the SINR value of the reception of the control signal. In addition, the module 410 allocation of frequency blocks determines which mobile station is allocated the frequency band, the magnitude of the SINR reception of the control signal. In addition, a module 414 define MCS determines the value of the MCS for the mobile station, which is allocated the frequency band and which is allowed to transmit (step S3810). When this module 412 to determine the transmission power may determine the transmission power for the mobile station, which is allocated the frequency band and which is allowed to transmit.

Module 404 to determine a resource allocation of the radio informs the mobile station that is allowed to transmit, and selection information for the data channel bandwidth (phase or frequency blocks) and used the value of MCS (step S3812).

Information about allocated to the data channel frequency band transmitted from the base station enters the module 122 controls the allocation of radio resources, and information about the importance of MCS enters the module 102 expanding the range and channel coding.

The module 102 expanding the range and performs channel coding channel coding by applying error-correction code, for example, turbo code or a convolutional code, comes to the overall sequence of binary information in accordance with the received information about the importance of MCS, thereby modulating the data subjected to channel encoding.

Module 114 of the signal in the frequency domain determines the amount of data in accordance with the selected frequency band. Information about the identifier (ID) of the user, the MCS value, the discriminator new/re-transmission and the amount of data multiplexers in the control channel. As a result, receives a frame transmission (step S3814).

Then the mobile station transmits the data channel (step S3816).

The data channel transmitted from the mobile station, demodulator and decode at the base station (step S3818).

The base station transmits a signal notification of successful/unsuccessful reception (ACK/NACK) in accordance with the results of demodulation and decoding.

The present international application is based on Japanese patent applications No. 2005-105492, No. 2005-174394, No. 2005-241899, No. 2005-317567 and No. 2006-031749, filed, respectively, on March 31, 2005 June 14, 2005, August 23, 2005 and October 31, 2005, in the Japan Patent office, the entire contents of which is incorporated into the present application by reference.

SUBSTANCE: base station communicates with a mobile station on an orthogonal frequency-division multiplexing (OFDM) scheme using any of two frequency bands or any of more than two frequency bands. The base station has apparatus for transmitting the synchronisation channel and the control channel using a frequency band which includes the centre frequency fA of the first frequency band (20 MHz) located in the raster and having width which is equal to or greater than the width of the second frequency band (5 MHz at the end). The control channel contains information in the centre frequency for determining the centre frequency fA of the second frequency band. Since the mobile station is tuned to the required band after obtaining information on the centre frequency using the frequency band with centre frequency lying in the raster, the mobile station can connect to the required frequency band without scanning frequencies which are not in the raster.

EFFECT: simple procedure of connecting to a downlink.
