The technical field to which the invention relates.

The present invention relates to a transmitting device and method of providing radio resource.

The level of technology

In the UMTS system (Universal Mobile Telecommunications System universal mobile telecommunications system), which relates to mobile communication systems of the third generation (third generation, 3G), as the standard variants of realization of high-speed packet communication channel (hereinafter referred to as downward communication channel) from the base station to the mobile station adopted the technology HSDPA (High Speed Downlink Packet Access high speed packet downlink).

To improve the throughput that can be obtained by using HSDPA, the technology planning packages, according to which users connect to the shared resources of the radio base station (hereinafter called a shared channel with packet transmission), and the base station provides radio resources for users with good signal conditions, based on a system of priorities.

In HSDPA technology transfer signal with a single carrier bandwidth of the channel is 5 MHz. Accordingly, the entire bandwidth of the channel in the 5 MHz band is used for data that is passed to the IDE signals on the shared channel with packet transmission, moreover, the provision of transmission intervals, each user is made mainly on the basis of temporal multiplexing. Also, is the transmission of a signal using the entire bandwidth of the channel is 5 MHz for the control channel to transmit information about what the user is granted the transmission interval, etc. to transmit on a shared channel with packet transmission.

On the other hand, began to address the standardization of long term evolution (long term evolution, LTE) of the UMTS standard, and research continues in the mobile communication system of the fourth generation (4G), which is following the 3G generation. In the long-term development of 3G and 4G systems preferred flexible support transition from mnogomodovoi environment, such as a cellular communication system, to the environment with isolated cells, such as the coverage area of the access points and the area inside the premises; it is also desirable to increase the efficiency of use of frequencies for both types of cellular environments.

As radio access systems adopted for the downward channel in the long-term development of 3G and 4G systems, OFDM (Orthogonal Frequency Division Multiplexing, multiplexing orthogonal frequency division)designed to transmit signals using the set of subcarriers is considered as a promising ka is Deedat (see, for example, non-patent document 1).

In the OFDM converts from sequential data set, designed to transfer, in parallel so that the parallel signals of the set of data is transmitted using multiple subcarriers. Accordingly, as the transmission rate of the symbols becomes low, the influence of delay waves (multipath propagation), arising from differences in the paths from the transmitter to the receiver is reduced, and thus, it becomes possible to transmit signals with high speed and high quality.

In addition, to support mnogomodovoi environment radio access systems using OFDM, it is desirable to apply the reuse frequency in one cell to obtain a large bandwidth. When implementing a reuse frequency in one cell to effectively use spread spectrum to suppress the influence of interfering signals using the same frequency, from the next adjacent cell.

Thus, in OFDM (OFDM expanded range), to which is applied an extension of the spectrum, as shown in figa and 1B, after the input is made channel coding and modulation data is applied to the expansion of the range and performs the serial-to-parallel conversion obratno Fourier transform; thus, signals are formed with many carriers which are transmitted after the introduction of a guard interval. In particular, in cases where there is a widening of the spectrum, when using the expansion coefficient of the spectrum, for example, 8 each symbol is divided into eight subcarriers and transmitted. In addition, if the effect of the interference from the surrounding hundred little, used the coefficient of expansion of the spectrum of 1, because to apply the enhancement spectrum is not required, so that each subcarrier is transmitted different data D1, D2,....

In the OFDM or OFDM using spread spectrum, as described above, can also be used by the technology planning packages using the shared channel as the channel used in HSDPA, and, accordingly, may be improved throughput. In this case, as in OFDM for transmission in the shared channel is a transmission on multiple carriers available not only a way to provide a transmission interval for each user based on time-multiplexing, as in HSDPA, but also available and providing radio resources to each user in units of subcarriers, or in terms of frequency blocks, which limited the set of subcarriers (see, for example, non-patent document 2).

Therefore, when the signal transmission, the IP is alzouma transfer with lot of bearing in the frequency band of the channel, you can use method for providing radio resources that is different from the technology used in HSDPA.

However, in order to really implement mobile communication in OFDM or OFDM with expansion of the range, in addition to the transmission of the shared channel you want to transmit the control channel, which is required for transmitting control information shared channel, or transmit a common control channel for transmitting system information and paging information that is sent to all users connected to the base station.

However, in the above-mentioned transmission used to transmit signals using multiple subcarriers, has the following problem.

In the downlink there is no optimal provisioning of physical radio channels to transmit different types of information.

Channel multicast is a channel designed for multicast.

The transmitting device according to a variant implementation of the present invention is described with reference to figure 3.

The transmitting device is installed, for example, in the base station and provides the transmission of the downward channel.

The transmitting device 100 transmits a common control channel and the signaling channel control the population, using the entire frequency band or at least the part of frequency bands, discretely located throughout the frequency band. Thus, it can be obtained the effect of diversity in the frequency domain.

In addition, the transmitting device 100 divides the time domain and the frequency domain, and transmits the shared channel based on the scheduling of packets to provide the user with the part corresponding to the status good. Respectively, can be obtained the effect explode multiple users.

Odul 116 expanding the range connected with module 140 provide radio resource.

Data from each user is served in the module 128 planning packages. In module 128 packet scheduling scheduling packets for user selection to provide shared channel based on the feedback information indicating the state of the radio coming from each user (receiving station). For example, the module 128 packet scheduling divides the time domain and the frequency domain to provide the land on which the state radio communications for the user high.

In addition, the module 128 packet scheduling determines the speed channel coding and modulation scheme of the data for the selected user. Module 128 planning package also defines the coefficient of expansion of the spectrum for the selected user. For example, the module 128 packet scheduling determines the modulation scheme of the data and the encoding rate of the data based on the information indicating the modulation scheme of the data and the coding rate for the level of quality of reception, is shown in figure 4, so as to transfer most effectively in accordance with a predetermined algorithm.

Information indicating the modulation scheme of the data and the coding rate for the level of quality of the reception is set so that the higher the level of reception quality, the greater the level of the modulation scheme of the modulation data and more encoding speed. For example, as improving the quality of reception is selected schema data modulation QPSK, 16QAM, and QAM. Regarding the encoding speed by increasing the level of the reception quality set of increasing values from 1/9 to 3/4. Specify here the modulation scheme of the data and the encoding speed is changed depending on the environment, cells and the like, which is equipped with a transmitting device.

In addition, the module 128 planning package gives the module 112 channel encoding module 124 modulation data and module 126 expanding the range of information collected in the planning of packages, such as, for example, the user ID indicating the selected user, and information such as control information indicating at least one of the following parameters: the coefficient of expansion of the range used for the transmission of the user, the encoding rate of the channel and the modulation scheme of the data.

In addition, the module 128 packet scheduling delivers data transmission of a user selected when scheduling packets in module 122 of the channel encoding and the information is provided in the module 124 modulation data.

The module 122 performs channel coding channel coding data transmission in accordance with the encoding rate of the channel selected by the scheduling of the packets, and sends the data transmission in the fashion of the ü 124 modulation data.

The module 140 provide radio resource provides a common control channel, the channel control signals and a shared channel, the radio resource.

Hereinafter in the description reference figure 5.

For example, when providing radio resources shared control channel and the signal of the specific control channel, as shown in configuration 1, the module 140 provide radio resource divides the entire frequency band allocated to a communication system, in units of subcarriers, each of which is formed one or more subcarriers, and provides at least one block of subcarriers, the transmission interval, denoted as a single element (TTI: Transmission Time Interval, the time interval of transmission) packet.

In addition, when providing radio resources of the shared channel module 140 providing resources radio provides radio resources other than the resources provided by the common control channel and a signaling control channel. Accordingly, for the General control channel and a signaling control channel is passing on a separate frequency regions across the frequency band, so that the reception quality in the receiving device can be improved due to the effect explode frequency.

Moreover, as shown in configuration 2, when providing radio resources shared control channel and a signaling control channel module 140 provide radio resource can provide a common control channel and a signaling control channel, at least part of the plurality of characters forming the transmission interval, which is denoted as a single element in front of the Chi (TTI: Transmission Time Interval, the time interval of the transmission) in the packet.

Also in this case, when assigning radio resources of the shared channel module 140 provide radio resource provides characters other than characters, which provided a common control channel or the signaling control channel. Accordingly, since the common control channel and a signaling control channel can be scattered across the frequency band, the reception quality in the receiving device can be improved due to the effect explode frequency.

In addition, as shown in configuration 3, when the radio resources shared control channel and a signaling control channel module 140 provide radio resource divides the entire frequency band allocated to a communication system, in units of subcarriers, each of which is formed one or more subcarriers on the axis of frequency, and divides the set of OFDM symbols into unit cells along the time axis so as to form a frequency blocks that use multiple carriers and multiple OFDM symbols.

The module 140 provide radio resource may select at least one frequency block of the multiple frequency blocks to provide a common control channel and a signaling control channel. In addition, the module 140 provide the Republic of the SAR radio can provide a common control channel and a signaling control channel, at least part of the plurality of OFDM symbols forming the frequency block.

Also in this case, when providing radio resources of the shared channel module 140 provide radio resource can provide at least one of the symbols and the frequency blocks that are different from the symbols provided by the common control channel and a signaling control channel. Accordingly, since the common control channel and a signaling control channel can be posted on a separate frequency regions in the entire frequency band, the reception quality in the receiving device can be improved due to the effect explode frequency.

The module 150 performs IFFT inverse fast Fourier transform of the input signal for the modulation scheme is OFDM.

The module 160 the introduction of a guard interval does adding a guard interval to the signal that should be transmitted, to generate symbol in the OFDM scheme. Guard interval is created by copying part of the header or the end of the symbol, which must be passed.

The following describes the provision of radio resources for each of channels: common control channel signaling control channel and a shared channel.

First is described the provision of radio resource common control channel from chick is kami on figa-6L.

The common control channel is information intended for reception by all users in the cell. In addition, you want users in a cell can obtain the information with the required spatial probability and with the required quality, for example with a predefined frequency of occurrence of errors. Thus, if the entire bandwidth during transmission uses only a narrow frequency band, the reception quality at the given frequency individually for each user and there is a risk of a user with a low reception quality depending on the situation. In addition, since the information is sent to all users, use the provision with packet scheduling for implementation of the transmission signal becomes impossible.

Therefore, in the General control channel packet scheduling is not applied, and the channel is available, the entire band of frequencies, or at least part of the frequency bands separately placed across the frequency band. Respectively, can be achieved explode frequency.

For example, when providing radio resources shared control channel, as shown in figa, the common control channel is provided at least one transmission interval and the transmission is performed using all of the bandwidth provided in the second transmission interval. Used in this way, the entire band of the reception quality in the receiving device can be improved due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in figv, the entire bandwidth allocated to the communication system, is divided into blocks of subcarriers, each of which is formed by the set of subcarriers and a common control channel sequentially placed at least in one of the blocks of subcarriers. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in figs, configurations 1 and 2 are combined in such a manner that the common control channel is at least one block of subcarriers in at least one transmission interval. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in fig.6D, the common control channel is part of the symbols of at least one transmission interval, and transmission is performed using the entire frequency band in a given symbol. According to the government, the use of the whole frequency band can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in figa, full frequency band provided to the communication system, is divided into blocks of subcarriers, each of which consists of a set of subcarriers, and a common control channel sequentially placed on the part of subcarriers in at least one block of subcarriers. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in fig.6F, configurations 3 and 4 are combined to accommodate the shared control channel on the part of subcarriers in at least one block of subcarriers in terms of symbols, at least one transmission interval. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, when providing radio resources shared control channel, as shown in fig.6G, a common control channel is placed in the part of the characters, at least one block of subcarriers in at least one transmission interval. In this case placed on the speaker control channel is placed in each transmission interval so his position is different, at least in part blocks subcarriers. Separation of the common control channel along the frequency axis and the time axis can improve the reception quality in the receiving device due to the effect of temporary explode in addition to effect separation of frequencies. For example, if the receiving device is moved at high speed, there is a decrease in the quality of reception at a certain frequency at a certain moment. In this case, through the implementation of the placement so that the position of General control channel to be placed in each block of subcarriers is different, at least in part block of subcarriers is the effect temporary explode and, as a result, improves the quality of reception.

In addition, as shown in fign, when providing radio resources shared control channel, the transmission interval described in relation to fig.6G, can be transmitted a predetermined number of times at intervals of predetermined duration. Accordingly, the repeated transmission of the same transmission interval can improve the reception quality in the receiving device due to the effect of temporary explode in addition to effect separation of frequencies. In this case, the time interval in which the broadcast transmission interval, is controlled by an adaptive way in chief of the dependence from the environment. For example, the transmission interval is set large in an environment similar to the office in which the movement is small, and the transmission interval is set short in the environment, such a city, where the movement is great. In addition, the placement can be performed so that the position of General control channel to be placed in the part of the characters, at least one subcarrier block in the transmission interval, the transmitted second or later differs from the position of the common control channel transmitted previously.

The position of the common control channel in each block of subcarriers is described in relation to fig.6G and 6N, fixed in advance is determined based on the predefined rules, as shown in Fig. In addition, the position of the common control channel in each block of subcarriers may be determined randomly in each block of subcarriers as shown in fig.6J.

In addition, fign, as shown in FIGC, information transmitted on the common control channel of the second, or later, is the same as transmitted initially. In this case, the receiving device performs demodulation and determines the presence/absence of error demodulation. If the error demodulation is missing, the receiving device is instructed not to accept the common control channel transmitted second or later. If you have about the flexible demodulation, information is reset and performs the demodulation of the common control channel transmitted second or later (the combination of packages is not running, type I).

In addition, as shown in fig.6L, in case of error demodulation information may not be discharged in order to carry out the combined packet common control channel transmitted second or later, and a common control channel, previously adopted for the re-demodulation (the combination of packages, type I). Respectively, can be improved reception signal-to-noise (signal-to-interference ratio, SIR).

In addition, as shown in fign, the common control channel transmitted second or later, we may share information that is different from the first information transmission. For example, the common control channel transmitted second or later can be configured to send a package, in which the thinning pattern different from the pattern of the first transmission is a combination of packages, type II). In this case, at the receiving side performs demodulation and determines the presence/absence of error demodulation. If the error demodulation is missing, the receiving device receives an indication of a rejection of the common control channel transmitted to the third or later. If there is an error demodulation, the data may not from lunatica and can be implemented combining packet common control channel, broadcast the second or later, and a common control channel received earlier, to re-demodulation. Respectively, can be improved coding efficiency.

In addition, as shown in fign, the common control channel transmitted second or later can be configured to transfer information other than information of the first transmission. For example, information indicating the shared control channel is divided into two or more components and transmitted separately. If the information is in the common control channel transmitted first, and the code redundancy is a common control channel, the transmitted second or later, the common control channel transmitted second or later cannot be decoded, if unable to receive channel control signals transmitted first.

In this case, the division information indicating the shared control channel at two or more components can improve the reception quality in the receiving device due to the effect of temporary explode. In this case, can be transmitted to the transmission interval to transmit information indicating the shared control channel, split it and package, specify the code redundancy.

In this case, you must first determine the number of components of the common control channel of the transmitting device and the receiving condition the device. Information that must be determined are the number of packets for the implementation of combination packages, the pattern thinning, group, and bits indicating a new or re-transmitted packet. Bit that indicates a new or re-transmitted packet, necessary to prevent an incorrect combination because of an error in a bit ACK/NACK.

The following describes the provision of resources of the radio channel control signals with reference to figa-7L.

The signaling control channel signal is transmitted for each user scheduled module 128 packet scheduling that is needed especially when a large number of users who require such planning in a cell, to be able to receive the signal with the desired spatial probability and the required quality, that is preloaded with the frequency of occurrence of errors. Therefore, the channel is available the whole frequency band or at least a part of the whole frequency band, discretely located throughout the frequency range, without the use of packet scheduling. Respectively, can be obtained the effect explode frequency.

For example, as shown in figa, the provision of the resources of the radio communication signal control channel this channel is provided at least one transmission interval, and transmitting the implementation of AESA using the entire frequency band in a given transmission interval. Such use of the entire frequency band allows you to get a higher quality of reception at the receiver due to the effect explode frequency.

In addition, as shown in figv, the provision of the resources of the radio signal on the control channel, the entire frequency band provided to the communication system, is divided into blocks of subcarriers, each of which contains a number of subcarriers, so that the signaling control channel sequentially placed at least in one of the blocks of subcarriers. Separation along the frequency axis can improve the reception quality at the receiving device due to the effect explode frequency.

In addition, as shown in figs, the provision of the resources of the radio communication signal control channel configuration figa and 7B are combined in such a way that the signaling control channel is at least one block of subcarriers in at least one transmission interval. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, the provision of the resources of the radio signal on the control channel, as shown in fig.7D, the signaling control channel is part of the symbols of at least one transmission interval, and transmission is performed using the present frequency band in a given symbol. Thus, when using the entire frequency band can be improved reception quality in the receiving device due to the effect explode frequency.

In addition, the provision of the resources of the radio signal on the control channel, as shown in Figi, the entire frequency band provided to the communication system, is divided into blocks of subcarriers, each of which consists of a set of subcarriers and a signaling control channel sequentially placed on the part of subcarriers in at least one block of subcarriers. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, the provision of the resources of the radio signal on the control channel, as shown in fig.7F, configuration pigs and 7D are combined so as to place the signal on the control channel on the multiple subcarriers in at least one block of subcarriers in multiple symbol, at least one transmission interval. Separation along the frequency axis can improve the reception quality in the receiving device due to the effect explode frequency.

In addition, the provision of the resources of the radio signal on the control channel, as shown in fig.7G, the signaling control channel is part of the symbols of at least one block of subcarriers is, at least one transmission interval. In this case, each transmission interval hosted signaling control channel is positioned so that its position is different, at least in part blocks subcarriers. Such location of the signaling control channel along the frequency axis and the time axis can improve the reception quality in the receiving device due to the effect of temporary explode in addition to effect separation of frequencies. For example, if the receiving device is moved at high speed, there is a decrease in the quality of reception on the frequency at a certain moment. In this case, by performing the placement so that the position signal of the control channel to be placed in each block of subcarriers is different, at least in part blocks subcarriers, which can be achieved explode in time so that the reception quality can be improved.

In addition, as shown in fign, the provision of the resources of the radio signal, the control channel of the transmission interval described with reference to fig.7G may be transmitted a predetermined number of times at predetermined time intervals. By transfer of a single transmission interval many times you can improve the reception quality in the receiving device due to the effect of temporary explode in to olnine to effect separation of frequencies. In this case, the time interval in which the broadcast transmission interval, is controlled by an adaptive way depending on the environment. For example, the transmission interval is set large in an environment similar to the office where the motion is small, and in an environment that is similar to the city where the movement is large, the transmission interval is set small. In addition, there may be such an arrangement that the position signal of the control channel is hosted on the part of the characters, at least one block of subcarriers in the transmission interval, the transmitted second or later differs from the position signal of the control channel transmitted previously.

The position signal of the control channel in each block of subcarriers is described with reference to fig.7G and 7H, predetermined fixed image on the basis of predefined rules, as shown in Fig. In addition, the position signal of the control channel in each block of subcarriers may be determined for each block of subcarriers randomly, as shown in fig.7J.

In addition, fign, as shown in FIGC, the signaling control channel, broadcast the second or later transmitted the same information, and passed first time. In this case, the receiving device performs demodulation and determines the presence/absence of error demodulation. If the error demodulation without the duty to regulate, the receiving device receives an indication of a rejection signal on the control channel, broadcast the second or later. If there is an error demodulation, the information is rejected and re-demodulation signal on the control channel, broadcast the second or later (the combination package is missing, type I).

In addition, as shown in fig.7L, in the case of error demodulation information may not deviate to perform a combination of packet signal on the control channel, broadcast the second or later and a signaling control channel, previously adopted for subsequent re-demodulation (the combination of packages, type I). Respectively, can be improved reception SIR.

In addition, fign shows the signaling control channel, the transmitted second or later, which can convey information that is different from the first information transmission. For example, the signaling control channel, broadcast the second or later can be configured to send a package, which made the thinning pattern different from the pattern of the first transmission is a combination of packages, type II). In this case, the receiving device performs demodulation and determines the presence/absence of error demodulation. If the error demodulation is absent, n is Yemen the device receives an indication of a rejection signal on the control channel, transmitted to the third or later. If there is an error demodulation, the information may not be rejected, this may be a combination of the packet signal on the control channel, broadcast the second or later and a signaling control channel received earlier, to re-demodulation. The result can be improved coding efficiency.

In addition, fign the signaling control channel, the transmitted second or later can be configured to transmit information other than information transmitted in the first place. For example, information indicating the signaling control channel is divided into two or more component and transmitted to the individual components. If the information is in the signaling control channel, the transmitted first, and the code redundancy is in the signaling control channel, the transmitted second or later, the signaling control channel, the transmitted second or later cannot be decoded, if unable to receive the signal on the control channel transmitted first.

In this case, the division information indicating the signaling control channel, two or more components can improve the reception quality in the receiving device due to the effect of temporary explode. In this case, can be transmitted to a transmission interval for transmitting information about nachusa common control channel, with her separation package and specify the code redundancy.

In this case it is necessary to determine in advance the number of components of the signaling control channel, the transmitting and receiving devices. The information required to determine in advance, includes the number of packets for the implementation of combination packages, the pattern thinning, group, and bits indicating a new or re-transmitted packet. Bit that indicates a new or re-transmitted packet, necessary to prevent an incorrect combination because of an error in a bit ACK/NACK.

As indicated above, to date documented cases of granting of radio resources shared control channel and a signaling control channel.

The following describes a method of providing radio resources to many of the common control channels and signaling channels.

In this embodiment, descriptions for each case of time multiplexing, the case for more use of frequency multiplexing and the case of additional use of code multiplexing.

First described case of time multiplexing.

In this case, as shown in Fig, the transmitting device includes the following components: module 110 forming whitefish is Ala shared control channel, which serves the data transmission sent by the General control channel, which is channel No. 1, the module 120 signal conditioning signal on the control channel, which is channel 2, which is provided with the information management module 128 packet scheduling module 140 providing resources Radiocommunication module 150 IFFT module 160 the introduction of a guard interval.

The module 140 provide radio resource includes the following components: module 131 switching, coupled with modules 106 and 116 of the spread spectrum module 132 controls the switching; module 133 conversion consecutive sets in parallel, connected to the module 131 switching. Module 133 conversion consecutive sets in parallel connected to the module 150 IFFT.

Module 132 controls the switching manages to switch broadcast channels for each character or each transmission interval. Module 131 switching regularly commutes broadcast channels according to the control signal from module 132 control for switching signals in a module 133 conversion consecutive sets in parallel.

For example, as shown in figa module 132 controls the switching divides the time domain into multiple regions in a given frequency block and performs switching for before the delivery of physical channels from a variety of common control channels and signaling channels management in a divided time areas. For example, the module 132 controls the switching performs switching to provide multiple physical channels common control channels and signaling channels control units of characters included in a separate temporary area, for example, for each of the channels№1, №2, №3...

In this case, the radio resources that are not available to any General control channel and/or signaling control channel, another feature of the physical channel, such as the following shared channel.

Thus, the use of at least one frequency block and providing a variety of common control channels and signaling channels management-level characters can improve the reception quality due to the effect explode frequency.

In addition, for example, as shown in figv module 132 controls the switching can perform switching for each transmission interval with the aim of providing multiple physical channels, such as channels No. 1, No. 2, including, for example, common control channels, the signaling control channels or both of these channels, a predetermined OFDM symbol frequency blocks included in the transmission interval.

In this case, the radio resources that are not available to any General control channel and/or the signal channel of the Board, another feature of the physical channel, such as, for example, the following shared channel. Accordingly, when providing a variety of common control channels, signaling channels or both of these channels, common control channels and the signaling control channels can be transmitted using the entire frequency band that will improve the reception quality due to the effect explode frequency.

The following describes the case of additional use of frequency multiplexing. Here we describe the transfer method that uses frequency multiplexing in conjunction with a time multiplexing if the number of physical channels, which allows multiplexing, little by using the above-described temporal multiplexing.

The transmitting device in the case of joint use of frequency multiplexing is different from the transmitting device described with reference to Fig, that the structure of the module 140 provide radio resource is different. The module 140 provide radio resource includes module 134 distribution of subcarriers connected to the modules 106 and 116 of the expansion of the spectrum, and module 135 control the distribution of subcarriers connected to the module 134 distribution is Odessa. The module 134 distribution of subcarriers is connected to the module 150 IFFT.

Module 135 distribution management determines subcarriers subcarriers for the allocation of common control channels and signaling channels and delivers the result to the module 134 distribution of subcarriers. The module 134 distribution of subcarriers performs allocation for shared control channels and signaling channels based on the received information on the subcarriers.

For example, as shown in figa module 135 control the distribution of subcarriers divides the bandwidth of each frequency block to many bands to provide a common control channels and signaling channels control the unit elements of the divided bands. In addition, the module 135 control the distribution of subcarriers can divide the time domain of the frequency blocks in many areas to change the common control channels and signaling channels, which is determined by each individual of the temporary area in the temporary separation.

For example, if we divide the bandwidth in each of the frequency blocks to two lanes and the division of the transmission interval of three module 135 control the distribution of subcarriers performs the General control channels, the signaling control channels, or both types of individual blocks, for example, is the analy No. 1, №2, №3...No. 6.

When using multiple frequency blocks thus providing a common control channels and signaling channels control strips isolated from a bandwidth of each frequency block is achieved by improving the quality of reception at the receiver due to the effect explode frequency.

In addition, for example, as shown in figv module 135 control the distribution of subcarriers can level intervals of the transmission to provide a common control channels, the signaling control channels, or both of them a predetermined OFDM symbol in the frequency blocks included in the transmission interval, such as, for example, channels №1, №2, №3 and №4.

For example, module 135 control the distribution of subcarriers provides a common control channels, the signaling control channels, or both types of pre-defined OFDM symbol in a given frequency blocks. In this case, the radio resources that are not available to any General control channel and/or signaling control channel, another feature of the physical channel, such as the following shared channel, and switching is performed in the regime of temporary separation.

Thus, when providing the common control channels, the signaling control channels, or both at the level h, the frequency blocks common control channels and the signaling control channels can be transmitted using separate parts in the full frequency band so the reception quality may be improved due to the effect explode frequency.

The following describes the case of additional use of code multiplexing.

The transmitting device in the case of additional use of code multiplexing is different from the transmitting device described with reference to Fig, that the structure of the module 140 provide radio resource is different. The module 140 provide radio resource includes a module 137 code multiplexing, coupled with modules 106 and 116 of the expansion of the spectrum, and the module 136 control code multiplexing, coupled with module 137 code multiplexing. Module 137 code multiplexing is connected to the module 150 IFFT.

The module 136 control code multiplexing manages the output signals from the code multiplexing from modules 106 and 116 of the expansion of the range, which range is expanding with the use of different spread spectrum codes. Module 137 code multiplexing performs code multiplexing of the input channels.

For example, as shown in Fig module 136 control code multiplexing provides each of the common control channels, signaling channels, or both as channels №1, №2, for example, the seat reservation particular OFDM symbol of the OFDM symbols, included in the transmission interval, the transmission interval for the implementation of the code multiplexing.

In this case, the radio resources that are not available to any General control channel and/or signaling control channel, another feature of the physical channel, such as the following shared channel.

Accordingly, when using multiple frequency blocks for performing code multiplexing for shared control channel and a signaling control channel may be improved reception quality due to the effect explode frequency.

The following describes the provision of radio resources of the shared channel.

Because of the shared channel is allocated to each user, it can be used planning packages. Relative to the direction of the axis frequency module 140 provide radio resource divides the entire frequency band provided to the communication system, on the single elements in one sub-carrier or set of carriers; about the direction of the time axis, the module 140 provide radio resource divides into unit cells on one or multiple OFDM symbols and divides the direction of the axis codes on single elements on one or more codes; thus, each often the hydrated block is composed of one or multiple subcarriers one or multiple OFDM symbols and one or multiple codes, and radio resources are available in single elements of the frequency blocks.

In addition, the module 140 provide radio resource performs the packet scheduling for time domain and frequency domain to select at least one frequency block of the multiple frequency blocks. The results of scheduling packets are communicated to the receiving station.

In addition, the module 140 provide radio resource provides optimal frequency blocks based on the feedback data from the receiving station and characterize, for example, the state of the receiving channel, using, for example, measure the SIR of the received signal.

Accordingly, the frequency blocks to be given to each user can be dynamically changed in a way that could be provided by the frequency blocks corresponding to the good channel. Respectively, can be improved reception in the receiving device due to the effect of multiuser diversity.

Next, with reference to Fig describes an example in which the number of users is eight. In other words, describes the case of radio resources of the shared channels for up to eight users.

The module 140 provide resourcerecovery divides the entire frequency band, provided by the communication system, for example, eight for the formation of frequency blocks and performs the provision of radio resource for each transmission interval in accordance with the reception state of each user. In this case, the frequency unit is a single element of the granted radio resource generated by dividing the bandwidth of the system into multiple bands in each transmission interval.

In addition, for example, if transmitted to each user data volumes are different, the module 140 provide radio resource can provide frequency blocks depending on the data rate. For example, the frequency block signal is provided to the high-speed data transmission, performing, for example, sending a large file, and the low-speed signal transmission, such as voice data. In case of high data rate packet size that you want to transmit is larger than the size of the frequency block. In the case of low data rate packet size to be transferred becomes smaller than the size of the frequency block.

The following describes a case of providing radio resource to the user with high speed data transfer with reference to Fig.

As in the case of high speed data transfer size of the package is, want to send exceeds the size of the frequency block, the module 140 provide radio resource provides a multiple frequency blocks in the transmission interval. For example, for user 1 with a high speed data transfer feature three frequency block in the transmission interval and the four frequency block in a different transmission interval.

The following describes a case of providing radio resource to the user with a low data transmission rate with reference to Fig.

As in the case of low data rate packet size that you want to transfer is less than the size of the frequency block, the module 140 provide radio resource provides one frequency block group of users with low data rate. Because the size of the package that you want to transfer less than the size of the frequency block, a user with a low data transmission speed can not fill one block of transmitted information. However, the use of only parts of the frequency block and transfer the remaining part of the blank is a waste of radio resources.

Thus, multiple users with low data transmission rate is one frequency block. For example, the module 140 provide radio resource provides users who is 9 and # 10 with a low transmission rate the same transmitted frequency block by multiplexing users. Accordingly, the reception quality can be improved due to explode multiple users.

In addition, when providing radio resources to users with low-speed data module 140 provisioning radio can simultaneously provide resources for at least two frequency blocks in multiple frequency blocks included in the same transmission interval. If users with low data rate is entirely one frequency block, it is possible to reduce the effect of the passing of many users because the provision is not necessarily a group of users with high quality.

In this case, radio resources are provided in parallel in multiple frequency blocks. For example, as shown in figa, each user No. 9, No. 10, No. 11 and No. 12 with a low transmission rate data in parallel are provided, at least two frequency block included in the same transmission interval. Respectively, can be achieved explode frequency, and the reception quality at the receiving device can be improved.

Although the provision of radio resources of the shared channels for users with low data rate shown in figa similar way pre is leaving radio resources effective in providing users moving at high speed, or users receiving status which is very bad. This is because, since a user with a high speed rate of change of the channel is very high, providing radio resources when planning packages is not enough time to follow the changes, so the effect of improvement from multi-user diversity can not be implemented. In addition, since the data rate for users with extremely poor reception is very low, a sufficient coding efficiency in the channel cannot be ensured only by providing part of a single frequency block, therefore, possible deterioration of communication performance. The user, under the above conditions, as shown in figv, in parallel provided the resources, at least two frequency blocks included in one transmission interval. Respectively, can be achieved explode frequency, and the reception quality in the receiving device can be improved.

Next, with reference to Fig describes the case of providing resources radio channel multicast. For group transmission data is transmitted from multiple transmitters, a single user.

As shown in the sample configuration 1, when the war is in relation to the resources of the radio channel group transmission module 140 provide radio resource provides channel multicast, at least part of the characters that form the transmission interval, which means a single transmission element (TTI: Transmission Time Interval, the time interval of transmission) when packet transmission.

In the case of providing radio resources a particular physical channel different from the channel group transmission module 140 provide radio resource also provides a character other than the characters that provided by channel group transfer. Accordingly, since the channel group transfer can be posted throughout the frequency band, the reception quality in the receiving device can be improved due to the effect explode frequency.

As shown in the sample configuration 2, the provision of the resources of the radio channel group transmission module 140 provide radio resource may provide the channel group transfer at least part of the characters that form the transmission interval, which means a single transmission element (TTI: Transmission Time Interval, the time interval of transmission) when packet transmission, and can provide for transmission of the same transmission interval several times, for example twice, using a variety of transmission intervals.

In the case of providing radio resources a particular physical channel different from the channel group transmission module 140 ol the delivery of radio resource also provides a symbol, other than the characters that feature channel multicast. Accordingly, since the channel group transfer can be posted throughout the frequency band, the reception quality in the receiving device can be improved due to the effect of passing frequencies. In addition, can be implemented by the effect of temporary explode.

In addition, in the sample configuration 2 channel multicast passed the second or later conveys the same information as transmitted in the first time. In this case, at the receiving side performs demodulation and determining the presence/absence of error demodulation. If errors demodulation no, you will be prompted to refuse reception channel group transmission, the transmitted second or later. For example, in many cases the user is located close to the transmitter may receive information during the first attempt. The team at the abolition of the reception channel group transmission, the transmitted second or later allows you to reduce power consumption from the battery.

When the demodulation error information is rejected and re-demodulation channel group transmission, the transmitted second or later. In addition, when the demodulation error information may not deviate to perform a combination of packet channel multicast transmitted WTO is passed or later and channel multicast, adopted earlier, to re-perform the demodulation. Accordingly, increases the rate SIR of the received signal.

In addition, in the sample configuration 2 channel multicast passed the second or later, we may share information that is different from the first information transmission. For example, channel multicast passed the second or later can be configured to send packets over which made the thinning pattern different from the pattern used in the first transmission. In this case, at the receiving side performs demodulation and determining the presence/absence of error demodulation. If errors no demodulation, the receiver receives an indication of a rejection channel multicast, broadcast the second or later. For example, in many cases the user is located close to the transmitter may receive information during the first attempt. Team on discontinuation of the user-channel multicast, broadcast the second or later allows you to reduce power consumption from the battery.

If an error occurred demodulation, the information may not be rejected in this case can be combined packet channel group transmission, the transmitted second or later, and channel group forehand and, taken earlier, to re-perform the demodulation. Respectively, can be achieved by increasing the efficiency of encoding.

In addition, in the sample configuration 2 channel multicast passed the second or later can be configured to transfer information other than the information transmitted during the first broadcast. For example, information indicating the channel multicast, can be divided into two or more fragments. If the information is in the channel multicast, broadcast at the beginning, and code redundancy in the channel multicast, broadcast the second or later, the channel multicast passed the second or later cannot be decoded, if a failure has occurred when receiving a channel multicast, broadcast in the first place.

In this case, the reception quality in the receiving device can be improved due to the effects of temporal diversity, which is implemented by dividing the data indicating the channel group transmission by two or more transmission. This may broadcast the transmission interval to transmit information indicating the channel group transmission division and the package containing the code redundancy.

In this case, the transmitting and receiving sides must be pre-defined number of components for the section is of channel multicast. It is necessary to enter the following data: the number of packets for combining packets, the pattern thinning, group, bit that indicates a new or re-transmitted packet. Bits indicating the package as a new or re-transmitted, to avoid incorrect combination taking into account the error symbol ACK/NACK.

The following describes a method of providing radio resources of the shared channel in the frequency block. The module 140 provide radio resource performs multiplexing of the shared channels in a frequency block that feature radio resources.

First described method of providing radio resources to the users with high speed data transfer.

For example, for a user with high speed data transfer module 140 provisioning radio performs the multiplexing of the signals of one user within the frequency block based on results of the scheduling frequency and time. For example, on Fig shows the process in which the module 140 provide radio resource combines temporal and frequency multiplexing for multiplexing signals from a single user.

The following describes a method of providing radio resources to users with low data transfer rate is about the reference to Fig.

For example, for a user with a low-speed data module 140 provide radio resource performs temporal multiplexing of the signals of multiple users within a frequency block based on results of the scheduling frequency and time. Respectively, can be achieved by increasing the reception quality due to the effect explode frequency.

In addition, for a user with a low-speed data module 140 provide radio resource may, for example, multiplexing frequency signals of multiple users within a frequency block based on results of the scheduling frequency and time. Respectively, can be improved reception quality due to the effect of temporary explode.

In addition, for users with low-speed data module 140 provide radio resource may, for example, multiplexing code signals of multiple users within a frequency block based on results of the scheduling frequency and time. Accordingly, compared with the time and frequency multiplexing can be achieved explode in time and frequency, which improves the quality of reception. In addition, the use of modulation scheme data rate is low, such as, for example, quadrature phase modulate the (QPSK) and binary phase shift keying (BPSK), reduces the effect of Nicodemou interference resulting from loss of orthogonality.

In addition, for example, for a user with a low-speed data module 140 provide radio resource may multiplex the signals of multiple users within the frequency block by combining time, frequency and code division multiplexing on the basis of the results of the planning frequency and time.

The following are detailed descriptions.

As mentioned above and shown in Fig module 140 provide radio resource performs temporal multiplexing signals for users with low speed data transmission within the frequency block. Respectively can be improved reception quality due to the effect of diversity of frequencies, especially in an environment with many users with low speed of movement.

On the other hand, as shown in figa, for users with high speed data transfer module 140 provide radio resource performs the combined multiplexing of the signals of the users within the frequency block by combining time and frequency multiplexing.

In addition, as shown in figv, for users with high speed data transfer module 140 provide resource radios the ides can perform multiplexing of the signals of the users within the frequency block by combining time and code multiplexing.

In addition, for users with low-speed data module 140 provide radio resource may additionally perform the multiplexing of the signals of the users within the frequency block by combining time, frequency and code division multiplexing.

For example, on figa and 23C shows the module 140 provide radio resource, which multiplexes the signals of multiple users within a frequency block in the frequency domain/time domain. On figa presents a case of providing a continuous time domain, figv presents a case of a separate temporary fields

In addition, for example, as shown in Fig module 140 provide radio resource can perform a random selection of blocks formed of subcarriers and OFDM symbols in the time/frequency domain for multiplexing signals of multiple users in the frequency block.

Next, as shown figa and 25V, module 140 provide radio resource may be, for example, multiplexing of the signals of multiple users in a frequency block in the time/area code. On figa presents a case of providing continuous frequency domain (hybrid temporal/code multiplexing, TDM/CDM), FIGU presents case is th provision of a separate frequency domains (hybrid temporal/code multiplexing, TDM/CDM).

Next, as shown figa and 26C, the module 140 provide radio resource may be, for example, multiplexing of the signals of multiple users in a frequency block in the frequency/code domain. On figa presents a case of providing a continuous time domain (hybrid frequency/code multiplexing, FDM/CDM), FIGU presents a case of a separate temporary areas (hybrid frequency/code multiplexing, FDM/CDM).

In addition, as shown in figa and 27B, the module 140 provide radio resource may be, for example, multiplexing of the signals of multiple users in a frequency block in the time/frequency/code domain. On figa presents a case of providing continuous frequency domains (hybrid temporal/frequency/code multiplexing, TDM/FDM/CDM), FIGU presents a case of a separate frequency domains (hybrid temporal/frequency/code multiplexing TDM/FDM/CDM).

As indicated above, the separation of time/frequency/code domain in the frequency block and providing the signal of each user area allows multiplexing of multiple users in the same frequency block.

The following describes the operation of the transmitting device is 100 according to the present invention with reference to Fig.

Information intended for transmission over a common control channel, is fed to the module 102 of channel coding. In module 102 channel coding channel is encoding the received information according to pre-set speed channel coding (step S2702).

Later in the module 104 modulation data modulation information, the last channel coding, according to pre-established modulation scheme data (step S2704).

Later in the module 106 expansion of the range is expanding the range of information held on the modulation data according to pre-set coefficient of expansion of the spectrum (step S2706).

On the other hand, the module 128 packet scheduling selects users and the schema definition of the data modulation and the coding rate for each selected user according to the received information intended for transmission to each user, and the reception quality of each user (step S2708).

Next, in module 122 of channel coding performs channel coding of the information intended for transmission to each user, with the speed of an encoder mounted module 128 packet scheduling (step S2710).

Later in the module 104 modulation data modulation information is intended is to send to each user, and the last channel coding, according to the modulation scheme of the data set module 128 packet scheduling (step S2712).

Later in the module 106 expansion of the range is expanding the range of information intended for transmission to each user and the previous modulation data according to the coefficient of expansion of the range set by the module 128 packet scheduling (step S2714).

In addition, the module 128 planning package gives the module 112 channel coding information for the selected user and the information about the selected modulation scheme data, the coding rate, etc.

In module 112 channel coding performs channel coding of incoming information with a preset speed channel coding (step S2716).

Later in the module 104 modulation data modulation data, past channel coding, according to pre-established modulation scheme data (step S2718).

Later in the module 106 expansion of the range is expanding the range of data that pass modulation data according to pre-set coefficient of expansion of the spectrum (step S2720).

Next, the module 140 providing resources radio provides radio resources of the information intended for transmission over a common control channel, information about the selected users, such info is prolonged, as the data about the selected modulation scheme of the data and the coding rate, and information intended for transmission to each user, based on the input information criteria used in the provision, such as channel type, data rate, mobility, etc. (step S2722).

After this, there is the formation and transmission of the OFDM signal (step S2724).

SUBSTANCE: methods are described to execute capacity control during operation in discontinuous transmission mode (DTX). UE sends along the upperlink during a transmission packet and receives TPC commands generated by the unit B on the basis of the upperlink transmission. UE may accept two TPC commands in the end of the transmission packet, which are not used during the transmission packet. UE preserves and saves these two TPC commands for subsequent transmission packet. In one version UE uses each preserved TPC command in one segment of the next transmission packet. In the other version UE combines two preserved TPC commands and applies combined value in the first two segments of the following transmission packet. In another version UE selects one of the preserved TPC commands and applies the selected TPC command in the first two segments of the following transmission packet.

EFFECT: efficient control of capacity in DTX mode.

Products of symbols are formed for the first stage, at least for two different delays, correlation is carried out between products for each delay and available values, and results of correlation for all delays are combined and used to announce the signal availability. For demodulation, synchronisation of input samples is adjusted to produce time-adjusted samples. Frequency deviation is assessed and removed from time-adjusted samples to produce samples with frequency correction, which are processed with the help of channel assessment to produce detected symbols. Phases of detected symbols are corrected to produce symbols with phase correction, which are demodulated, alternated backwards and decoded.

SUBSTANCE: invention discloses a communication method and device for selecting the number of code channels and the associated expansion coefficient for CDMA transmission. According to the invention, a set of permissible pairs of parametres, where the parametres are the number of code channels and the associated expansion coefficient, is determined in accordance with at least one first selection criterion. The pair of parametres from the set of permissible pairs of parametres for CDMA transmission is then selected in accordance with at least one second selection criterion. In that selection process, the expansion coefficient is used as a second selection criterion with a higher value, preferably compared to a lower value, if both expansion coefficients are lower or equal to a threshold expansion coefficient value.

EFFECT: invention takes into account the fact that in defined mode, low expansion coefficients give rise to a forbidden high processing load and lead to increase in intersymbol noise.
