Description

TRANSMISSION APPARATUS, RECEPTION DEVICE, MOBILE COMMUNICATIONS SYSTEM AND TRANSMISSION CONTROL METHOD FIELD OF THE INVENTION The present invention relates to a transmission apparatus, a receiving apparatus, a communication system and a transmission control method.

BACKGROUND OF THE INVENTION A fourth generation (4G) mobile communications method that is the next generation of IMT-2000 (International Mobile Telecommunications 2000) is under development. The fourth generation (4G) method is expected to flexibly support diverse environments from a multi-cell environment including a cellular system to an isolated cell environment such as a hot spot area and an indoor area, and increase utilization efficiencies of frequency in both cellular environments. In the fourth generation communication method, the following radio access methods have been proposed for a connection from a mobile station to a base station (referred to as an uplink, hereinafter). As the simple carrier transmission methods, a method has been proposed REF. : 186404 Multiple Access Division of Direct Sequence Code (DS-CDMA), a Multiple Access Method of Interleaved Frequency Division (IFDMA), and a Variable Dispersion Method and CDMA of Chip Repetition Factors (VSCRF-CDMA for its acronym in English), for example. As a multiple carrier method, an Orthogonal Frequency Division Multiplexing (OFDM) method, an OFDM Dispersion method, a Multiple Carrier Code Division Multiple Access method (MC-CDMA per its acronym in English) and an OFDM method of Dispersion of Variable Dispersion Factor (VSD Dispersion OFDM). The simple carrier method provides high energy efficiency because the peak power or energy is lower in terms of power consumption in a terminal, which reduces the unlocking of a transmit power amplifier. As an example of simple carrier methods, the VSCRF-CDMA method is explained with reference to Figure 1 (See document 1 related to the patent). A spreading portion 1 includes a code multiplication portion 2, a repetitive synthesis portion 8 connected to the code multiplication portion 2, and a phase shift portion 10 connected to the repetitive synthesis portion 8.

The code multiplication portion 2 multiplies a transmission signal by a scatter code. For example, a multiplier 4 multiplies the transmission signal by a channelization code defined under a dispersion ratio SF of predetermined code. In addition, a multiplier 6 multiplies the transmission signal by a secret code. The repetitive synthesis portion 8 compresses the dispersion transmission signal in a temporal manner and performs the chip repetition a predetermined number of times (CRF times). The transmission signal to which the repetition has been applied has a frequency spectrum in the form of a comb. When the repetition number CFR is equal to one, the repetitive synthesis portion 8 has the same configuration and operations in the usual DS-CDMA method. The phase shift portion 10 deviates (or shifts) a phase of the transmission signal by a predetermined frequency set specifically for each mobile station. In the VSCRF-CDMA method, when the CRF is greater than 1, for example, equal to 4, a frequency spectrum in the form of a comb used by each user is accommodated in a distributed manner over the entire band, as shown in Figure 2A. In this case, a specific frequency offset of the user is smaller than an allocated bandwidth. On the other hand, when CRF is equal to 1, the spectrum used by each user is accommodated on a block, as shown in Figure 2B. In this case, the user's specific frequency offset is greater than the allocated bandwidth. In addition, a radio access method has been proposed where a frequency spectrum in the form of a comb in the frequency domain is obtained (see documents 1, 2, not patent). A transmission apparatus 30 to which a radio access method is applied includes an FFT portion 12 to which a dispersion data sequence, a ratio or rate conversion portion 14, is input, connected to the FFT portion 12, a frequency domain signal generation portion 16, connected to the ratio conversion portion 14, an IFFT portion 18 connected to the frequency domain signal generation portion 16, a GL addition portion 20 connected to the IFFT portion 18, and a filter 22 connected to the Gl addition portion 20, as shown in Figure 3. The portion 12 of the Fast Fourier Transformation (FFT) divides the dispersion data sequence every Q chips in blocks, and performs a fast Fourier transformation, with which the blocks are transformed into the frequency domain. As a result, simple carrier signals of Q are obtained in the frequency domain. Incidentally, the dispersion data sequence corresponds to an output signal of the multiplier 6 in the dispersion portion 1 explained with reference to Figure 1. The rate conversion portion 4 repeats a predetermined number of times, for example , CRF times the Q accounts of the simple carrier signals. As a result, the number of the simple carrier signals generated is Nsub = Q x CRF. The frequency domain signal generation portion 16 shifts each single carrier signal on the frequency axis, so that the spectrum becomes comb-shaped. For example, when a process corresponding to CRF = 4 is carried out, three zeros are arranged between each simple carrier signal. As a result, the comb-like frequency spectra explained with reference in Figures 2A and 2B are formed. The IFFT portion 18 performs a fast inverse Fourier transformation on the comb-shaped spectra obtained by moving each single carrier signal over the frequency axis. The addition portion of the protection interval adds protection intervals to a signal to be transmitted. The protection intervals are obtained by replicating a portion of the upper part or the end of a symbol that is to be transmitted. The filter 22 performs a band limitation on the transmission signal. On the other hand, the multiple-carrier method, which has a long symbol, can provide improved reception quality in a multipath or path environment by providing the protection intervals. As an example, the OFDM method is explained with reference to Figure 4. Figure 4 is a block diagram of a transmission portion used in a transmission apparatus of the OFDM method. The transmission portion 40 includes a serial / parallel conversion portion (S / P) 32, a subcarrier mapping portion 34, connected to the S / P conversion portion 32, an IFFT portion 36 connected to the portion 34 of subcarrier mapping, and a portion of addition of Gl connected to the portion 36 of IFFT. Portion 32 of serial / parallel conversion (S / P) converts the sequences of signals into series to sequences of parallel signals. The subcarrier mapping portion 34 assigns each bearer each signal that is converted to the parallel signal sequence in the serial / parallel conversion portion 32. For example, the portion 34 of subcarrier mapping, allocates discrete subcarriers to each user as shown in Figure 5A, in order to obtain a frequency diversity effect. In addition, the subcarrier mapping portion 34 assigns consecutive subcarriers to each user as shown in Figure 5B. The portion 36 of fast inverse Fourier transformation (IFFT) performs the fast inverse Fourier transformation on the input signal, to thereby perform the modulation of the OFDM method. The addition portion 38 of the protection interval adds protection intervals to a signal to be transmitted and generates a symbol of the OFDM method.

Incidentally, in all the figures to describe the examples, similar reference marks are given to members or components having similar functions and the unnecessary repetition of the description is omitted. A mobile communications system according to an example of the present invention includes a mobile station and a base station capable of performing radio communication with the mobile station. A transmission apparatus according to an example of the present invention is described. The transmission apparatus is provided, for example, in the mobile station and transmitted through an uplink channel. The transmission apparatus according to this example is used in a cellular environment and a local area environment. As shown in Figure 6A, the cellular environment includes the base stations that cover the cells (sectors), for example, the base stations 200 ?, 2002, 2003, 2004 and 2OO5, and a mobile station 300 capable of performing the radio communication with the base station 200 ?. The cellular environment has a larger cell radius and a higher transmission power of the mobile station than the local area environment. However, a feasible data rate is lower in the cellular environment due to interference from the neighboring cells.

Therefore, the simple carrier method is more advantageous than the multi-carrier method with an uplink radio access method in the cellular environment. On the other hand, the local area environment such as an indoor environment or a hot or critical environment includes a base station that covers a cell (sector) such as a base station 2006 and a mobile station 300 capable of radio communication with the base station 2006. The local air environment has a smaller cell radius and lower power consumption of the mobile station than the cellular environment. However, the feasible proportion of data is relatively higher in the local area environment. Therefore, the multi-bearer method is more advantageous than the simple bearer method as the uplink radio access method in the local area environment. Next, with reference to Figure 7, the transmission apparatus according to this example is described. A transmission apparatus 100 includes a portion 102 of dispersion and channel code to which symbol sequences are input, a switching portion 106 connected to the spreading portion 102 and channel code, a fast transforming portion of Fourier (FFT) 108, and a portion 110 of serial / parallel conversion (S / P) connected to the switching portion 106, and a rate conversion or portion 112, connected to the FFT portion 108 and the S / P conversion portion 110. In addition, the transmission apparatus 100 according to this example includes a frequency domain signal generation portion 114, connected to the portion conversion portion 112, a portion 116 of fast inverse Fourier transformation (IFFT) connected to the frequency domain signal generation portion 114, a protection interval addition portion (Gl) connected to the IFFT portion 116, and a filter 120 connected to the addition portion 118 of Gl. In addition, the transmission portion 100 according to this example includes a data modulation control / dispersion rate / channel coding control portion 104, connected to the dispersion portion 102 and channel code., and the generation portion 114 of the frequency domain signal, and a radio resource allocation control frequency 122 connected to the frequency domain signal generation portion 114. The switching portion 106 is connected to the filter 120. To the data modulation / spreading speed / channel coding portion 104 the MCS information (Modulation and Coding Scheme) is entered for each user. To the radio resource allocation control portion 122 is entered the notification information indicating the allocation of radio resources to each physical channel, and the training indicating a programming result for each user. The data modulation control / spreading speed / channel coding control portion 104 determines a rate of dispersion of the orthogonal codes used in the spreading portion 102 and channel code, and outputs the orthogonal codes of the spreading rate determined and a specific secret code of the cell, as well as the MCS information entered, for each user to the dispersion portion 102 and channel code. For example, in the cellular environment, the data modulation control / spreading speed / channel coding control portion 104 determines an orthogonal code of a rate or dispersion rate corresponding to the cellular environment and the cell-specific secret code. On the other hand, in a local area environment, the data modulation control / dispersion speed / channel coding control portion 104 determines an orthogonal code of a dispersion velocity corresponding to the local area environment and the specific secret code of the cell. In addition, the data modulation control / spreading speed / channel coding control portion 104 outputs the number of subcarrier groups to the frequency domain signal generation portion 114. Dispersion portion 102 and channel code performs channel coding by applying an error correction code such as a turbo code or a convolution code to the input binary information sequence, according to the MCS information entered. , and in this way modulates the data encoded by channel. In addition, the dispersion and channel code portion 102 generates a dispersion chip sequence by conducting a dispersion process using the orthogonal input codes of the dispersion rate and the specific code of the cell, and from this send mode the output of the dispersion chip sequence to the switching portion 106. The switching portion 106 determines whether the information, which is provided by the base station 200 and indicates the radio access methods, shows the carrier method simple or the multiple carrier method. When the switching portion 106 determines that the imparted information indicating the radio access method shows the simple bearer method, the switching portion 106 outputs the incoming spreading chip sequence to the FFT portion 108. When the switching portion 106 determines that the imparted information indicating the radio access method shows the multiple bearer method, the switching portion 106 determines that the imparted information indicating the radio access method, shows the bearer method multiple, the switching portion 106 outputs the input spreading chip sequence to the S / P conversion portion 110. In addition, the switching portion 106 outputs the imparted information, indicating the radio access method to the filter 120. For example, the switching portion 106 determines a radio access method according to the notification information from the base station 200. In this case, the base station 200 determines in a portion 402 of radio access method determination (described below) if the single bearer method or the multiple bearer method is allowed to be used by each user (mobile station), and imparts the control information indicating the determined radio access method, to the mobile stations 300 as shown in Figure 8. In addition, the switching portion 106 can determine the simple bearer method or the multiple bearer method according to the radio access method determined for each cell, for example. In this case, the portion 402 of determining the radio access method of the receiving apparatus provided in the base station 200, gradually determines in advance the uplink radio access method for each base station, according to the configuration of cell. For example, when the base station 200 is installed, the radio access method determination portion 402 determines the radio access method used in accordance with the cell configuration, eg, a cell radius, the presence or the absence of neighboring cells, or similar. For example, the simple carrier method is used when the cell radius is large, whereas the multiple carrier method is used when the cell radius is small. The radio access method determination portion 402 imparts the information indicating the determined access method, such as the control information common to all users, to the mobile stations 300, as shown in Figure 9. According to the above, the radio access method is determined when the base station is installed, which leads to simplified configuration and control. In addition, the switching portion 106 may determine the simple bearer method or the multiple bearer method according to the radio access method determined for each user (mobile station), for example. In this case, the access methods can be switched according to the distance between each user and the base station, or the transmission power margin in each user. For example, when the access methods are switched according to the distance between each user and the base station 200, the propagation loss may be used, for example, as an amount corresponding to the distance between a user and the base station 200. In this case, the mobile station 300 measures the propagation loss in a downlink, using the downlink pilot signal reception energy, and in this way reports the information indicating the propagation loss measured to the base station 200, through the uplink. The determination portion of the radio access method 402 of the receiving apparatus provided in the base station 200 determines that the distance between the base station 200 and the mobile station 300 is large when the received propagation loss value is greater than a default threshold, and determines the use of a simple carrier method. Then, the determination portion of the radio access method 402 imparts the use of a simple bearer method to the mobile stations 300 as common control information dedicated to a user, as shown in Figure 10. The determination portion 402 of the radio access method of the receiving apparatus provided in the base station 200, determines that the distance between the base station 200 and the mobile station 300 is small when the value of the received propagation loss is smaller than a predetermined threshold, and determines the use of a simple carrier method. Then, the determination portion of the radio access method 402 imparts the use of a simple bearer method to the mobile stations 300 as common control information dedicated to a user, as shown in FIG.

Figure 10 In such a way, the radio access methods are controlled for each mobile station according to the distance between the base station and the corresponding mobile station. further, the mobile stations can determine the use of the simple bearer method or the multiple bearer method according to the measured propagation loss and report the determined result to the base station 200. In addition, when the access methods are switched in accordance with the transmission power margin in each user, "(maximum tolerance transmission power) - (the current transmission power)" can be used for example, as an indicator of the transmission power margin in each user. In this case, each of the mobile stations reports a value indicating "(the maximum tolerance transmission energy) - (the current transmission power)" to the base station. The portion 402 of determining the radio access method of the receiving apparatus provided in the base station 200, determines that the margin in the transmission power is small when the value indicated "(the maximum tolerance transmission power) - ( the current transmission power) "is smaller than a predetermined threshold, and determines the use of a simple carrier method. In this way, the portion 402 for determining the radio access method imparts the information to the mobile stations 300, as shown in Figure 10. On the other hand, the portion 402 for determining the radio access method of the radio communication device. reception provided in the base station 200, determines that the transmission power margin is large when the value that indicates "(the maximum tolerance transmission energy) - (the current transmission power)" is greater than a predetermined threshold, and determines the use of the multiple carrier method. Then, the portion 402 for determining the radio access method imparts the use of the multiple bearer method to the mobile stations 300, as shown in Figure 10. According to the foregoing, the access methods are controlled in accordance with the operation of each mobile station. In addition, the mobile stations 300 can transmit information indicating the maximum tolerance transmission energy and the information indicating the current transmission energy. Then, the portion 402 of determining the radio access method of the receiving apparatus provided in the base station 200 can calculate "the maximum allowable transmit power-the current transmit power" and controls the radio access methods according to with the calculated value. In addition, the mobile stations can determine the use of the single bearer method or the multiple bearer method according to the transmission power margin and thus report the determined result to the base station 200. In addition, the switching portion 106 it can transmit a measurement signal of the channel conditions, for example, a pilot signal, using a predetermined frequency band, required to be assigned, according to the radio access method determined for each user (mobile station), as it is shown in Figure 11. For example, the switching portion 106 transmits the measurement signal of the channel conditions, using only a frequency band allocated among the frequency bands assigned to the system. Specifically, when the frequency band of, for example, 20 MHz is assigned to the system, mobile stations (transmitting apparatus) are categorized into classes of mobile stations that can use 20 MHz, 10 MHz and 5 MHz. In this case , the switching portion 106 transmits the measurement signal of the channel conditions using only the frequency band corresponding to a class of the mobile stations (transmission apparatus) according to the radio access method determined for the user (station mobile) . A portion 404 of determination of radio resource allocation, of the receiving apparatus 400, allocates a frequency band to the mobile station (transmission apparatus) to which the measurement signal of the channel conditions is transmitted., according to the frequency band used to transmit the measurement signal of the channel conditions. Namely, each mobile station (transmitting apparatus) transmits the pilot signal, and the base station (receiving apparatus) measures the pilot signals and in this way the channel conditions between the base station and the mobile stations, thereby performs the assignment of the frequency bands. Mobile stations do not have to transmit the pilot signals using the entire frequency band assigned to the system. But the mobile stations can transmit the pilot signals using the predetermined bands. The base station receives the pilot signal from each user and assigns the frequency bands if there is a band to be allocated in the frequency band range. Then, the base station transmits the information indicating the frequency bands determined to the transmission apparatus. In addition, the receiving apparatus 400 can determine in the portion 402 for determining the radio access method, the frequency bands for use in transmitting the measurement signal of the channel conditions and thereby transmitting the information that indicates the frequency bands. In addition, the switching portion 106 may include a pilot signal generating portion, which transmits to the base station at least one of the information indicating a required (maximum) transmission bandwidth of a data channel, the information that it indicates a quantity of data to be transmitted and the information indicating a data rate, according to the access method determined for each user (mobile station) when the radio access method determined is the simple carrier method. In addition, the pilot signal generation portion may transmit information indicating a required (maximum) transmission bandwidth of the pilot signal to the base station. For example, the generating portion of the pilot signal transmits to the base station at least one of the information indicating the required (maximum) transmission bandwidth of the pilot signal, the information indicating the required transmission bandwidth (maximum) of the data channel, the information that indicates the amount of data that will be transmitted, and the information that indicates the data rate, through a channel based on contention. For example, the maximum transmission bandwidth is 5 MHz and the required transmission bandwidth is narrower than 5 MHz. As shown in Figure 12A, it is assumed that W_able is the maximum bandwidth that can be used by the mobile station; Wp_req is the maximum transmission bandwidth required of the pilot signal; and Wd_req is the required (maximum) transmission bandwidth of the data channel. The generation portion of the pilot signal determines Wd_req within a range of Wd_req = < W_able according to the amount of data that will be transmitted and the data rate. In addition, the pilot signal generation portion determines Wp_req within a range of Wd_req = < Wp_req = < W_able. The switching portion 106 may determine that the transmission bandwidth of the measurement signal of the channel conditions is an integral multiple of the minimum transmission bandwidth determined in the system or 2n times the minimum transmission bandwidth determined in the system. In this case, the switching portion 106 performs the transmission using a maximum transmission bandwidth where an expected received SINR when transmitting with the maximum transmit power or the "maximum transmission power-delta P" may exceed a received SINR. , required. For example, the switching portion 106 calculates the received, expected SINR according to an average interference power or power in the base station, and an average propagation loss between the base station (receiving apparatus) and the mobile station ( transmission device). For example, when the maximum transmission bandwidth is 5 MHz and the minimum transmission bandwidth is 1.25 MHz as shown in Figure 12B, a transmission bandwidth satisfying the received SINR, required from the signal measuring the channel conditions, is 1.25 MHz and 2.5 MHz between the transmission bandwidths, namely 1.25 MHz, 2.5 MHz and 3.75 MHz. Therefore, the maximum transmission bandwidth that can exceed the received SINR, required, is 2.5 MHz. In this case, even when the received SINR, required, is not expected to be realized in the case of transmission using the minimum transmission bandwidth, the transmission bandwidth used it does not become narrower than the minimum transmission bandwidth, and the transmission is performed using the minimum transmission bandwidth. The received SINR, required of the measurement signal of the channel conditions is imparted through the broadcasting channel, throughout the length of the cell. In addition, the switching portion 106 may adjust a different required quality for the measurement signal of the channel conditions, separately from the quality required for the data channel, for example, the received SINR, required. In this case, each required quality is imparted from a base station apparatus through the broadcasting channel to the mobile stations managed by an interested sector. For example, the base station apparatus imparts the quality required for the data channel using a dedicated control channel. The switching portion 106 performs control of the transmission power based on the quality required for the measurement signal of the channel conditions when no data channel is assigned, and only the measurement signal of the transmission conditions is transmitted. channel. For example, the switching portion 106 performs the transmission with a transmission energy determined by the transmission power control according to the quality required when transmitting the pilot signal. For example, the switching portion 106 establishes a required low quality necessary and sufficient for the measurement of the channel conditions, as shown in Figure 12C. With this, the interference by the pilot signals is reduced, which improves the performance as a whole. The switching portion 106 performs control of the transmission power for a data portion and the portion of the measurement signal of the channel conditions according to the quality required for the data channel, when the data channel is assigned. For example, the switching portion 106 performs the transmission with the same power as the data portion, when the data channel is assigned, as shown in Figure 12D. In this case, a higher required quality is adjusted for the data portion since a highly efficient modulation method and / or coding rate is used. Switching portion 106 transmits the pilot signal with a higher transmission power, since a highly accurate channel estimate is required. Specifically, when the data channel is allocated and an allocation bandwidth for the data channel is narrower than the transmission bandwidth for the measurement signal of the channel conditions, the switching portion 106 controls the power of transmitting the signal of measurement of the channel conditions to be a transmission energy satisfying the required quality of the data channel, for example, the received SINR, required in the transmission bandwidth for the measurement signal of the channel conditions, as shown in 12E. When there is not a sufficient margin in the transmission energy and the required quality is not satisfied, the switching portion 106 adjusts the transmission energy to the maximum, as shown in Figure 12F. The base station 200 determines a center frequency and a transmission frequency bandwidth (transmission bandwidth) of the pilot signal transmitted by the mobile station according to the information transmitted by the mobile station, for example, the width of The required (maximum) transmission band of the pilot signal, and thus imparts the information indicating the determined center frequency, and the information indicating the determined transmission bandwidth of the pilot signal to the mobile stations. The generating portion of the pilot signal transmits the pilot signal according to the imparted information indicating the center frequency and the imparted information indicating the transmission bandwidth of the pilot signal. Further, when the identity (ID) of the frequency block is imparted, the generating portion of the pilot signal transmits the pilot signal according to the transmission bandwidth and the center frequency designated by the ID of the given frequency block. In this case, the generating portion of the pilot signal can transmit the pilot signal by a frequency balance method. In addition, the generating portion of the pilot signal can transmit the pilot signal through the frequency balance by changing the bands for use in transmission for each assigned band. The FFT portion 108 divides the dispersion data sequence every Q chips into blocks, performs the fast Fourier transformation to transform the divided sequence into the frequency domain, and outputs the transformed divided sequence to the conversion portion 112 of proportion or speed. As a result, the Q accounts of the simple carrier signals are obtained in the frequency domain.

Serial / parallel conversion portion (S / P) 110 converts the Q signal (current) sequences into series in plural parallel signal sequences, and thereby outputs the parallel signal sequences to the rate conversion portion 112. The rate conversion portion 112 repeats a number predetermined times, eg, CRF times the Q single carrier signals sent out from the FFT portion 108. As a result, the number of simple carrier signals generated is Nsub = Q x CRF. In addition, the rate conversion portion 112 outputs the Q parallel signal sequences that have been output from the serial / parallel (S / P) conversion portion 110 to the domain signal generation portion 114. of frequency. On the other hand, the radio resource allocation control portion 122 controls the time and frequency blocks assigned to each physical channel according to the notification information indicating the allocation of radio resources to each physical channel imparted by the radio channel. the base station 200 and the information indicating a programming result for each user. In addition, radio resource allocation control portion 122 controls the allocation of radio resources for a certain period, based on the time scale of the length of the Transmission Time Interval (TTI) of the multiple blocks of radio. frequency when the blocks of frequency and time are assigned to each physical channel. Next, with reference to Figures 13 and 14, the programming of the shared data channel is explained. The shared data channel is assigned according to the programming in the base station 200 as described below. The frequency blocks are assigned according to the programming control information in the time domain in the frequency division multiplex access where the frequency is firmly assigned, as shown in Figure 13. In this case, they are assigned Multiple blocks of frequency to high-speed data users, which allows each user to use only the frequency blocks assigned in advance. In this way, the transmission apparatus 100 does not have to transmit in advance the pilot channels in other frequency blocks that are transmitted so that the receiving apparatus 400 is able to measure a channel quality indicator (CQI). An optimum bandwidth of the frequency block is 1.25 to 5 MHz, for example. By widening the bandwidth of the frequency block, the diversity effect of multiple users can be increased in the frequency block. When simple bearer transmission is performed, the bandwidth assigned to each user can be variable according to the data rate. In addition, when the traffic size of a certain user is larger than the load size of the frequency block, a frequency block can be used exclusively by a user. A localized FDMA, which is a narrower FDMA accommodated on the frequency block, is used by multiple low-speed data users. Namely, the spectrum used by the spectrum used by each user is accommodated on the block as described with reference to Figures 2A and 2B. In addition, the frequency spectrum in the form of a comb used by each user can be distributed over the entire band. Other users use the spectrum in the form of a comb. The localized FDMA can be mainly used in the shared data channel. In addition, a band, for example, a frequency block can be assigned to multiple users, as shown in Figure 14. In this case, frequency multiplexing using the frequency spectrum in the form of a comb is used. Alternatively, multiple users are multiplexed in a frame or frame in a manner described as follows. The chip information by a certain unit is stored divisionally in time in TTI. This chip information is used as a unit to change the frequency used for the transmission. As established, multiple users are assigned to a certain band and the transmission is made using the frequency hop. By assigning a certain frequency band to multiple users, the interference from other cells (sectors) is averaged. Therefore, the fluctuations of the interference from other cells (sectors) can be reduced compared to a situation where the users are changed in a certain frequency band to carry out the transmission. Next, the following explanation is based on a situation where a coverage area covered by the base station 200 is composed of three sectors 250, 2502, 2503; an A300 mobile station? exists in sector 250]; and a mobile station B3002, a mobile station C3003, a mobile station D3004, and a mobile station E3005 exist in sector 2503, for example, as shown in Figure 15. When the frequency blocks are assigned to each user, if another mobile station in a neighboring sector exists near the mobile station in question, the interference energy becomes larger, while the interference energy becomes lower if the other mobile station exists further away.

For example, the mobile station A300 ?, which exists in sector 250? is influenced to a large extent by the interference power from the mobile station D3004 which exists in the neighboring sector 2503 and is assigned near the mobile station A300 ?, but not greatly influenced by the interference power from the mobile station E3005 that exists further away. Therefore, the interference energy varies with time as shown in Figure 16A. On the other hand, when the frequency hopping and frequency division multiplexing access using the comb-like frequency spectrum are performed, the interference energy is averaged as a whole and becomes substantially constant, as shown in FIG. Figure 16B, which reduces the temporal variations of the interference energy. In this case, although the transmission energy per user is reduced, the efficiency per user remains unchanged when performing the continuous assignment over multiple time periods, which reduces the variations of the interference from other cells (sectors). In addition, the frequency blocks can be assigned according to the control information on the time domain programming and the frequency domain, as shown in Figure 17.

In this case, the pilot channel that is transmitted in order for the receiving apparatus 400 to measure the channel quality indicator (CQI) is transmitted over all the frequency blocks, namely over all the channel bandwidths . In addition, when a traffic size of a certain user is larger than a load size of the frequency block, a frequency block can be exclusively used by a user. When there are multiple low data rate users, a frequency block is used by multiple users. In this case, the orthogonal frequency spectra namely the narrower FDMA (localized FDMA) that is accommodated on the frequency block, or the comb-like spectrum (distributed FDMA) is applied to the same frequency block. Namely, as described with reference to Figures 2A and 2B, the spectrum used by each user is accommodated on the block within the frequency block. In addition, the frequency spectrum used by each user can be distributed and accommodated in the form of a comb on the frequency block, which reduces the interference of multiple users. An optimum bandwidth of the frequency block is 0.3125 to 1.25 MHz, for example. By narrowing the bandwidth of the frequency block and programming the channel in the frequency domain, the diversity effect of multiple users can be increased. When simple bearer transmission is performed, the bandwidth assigned to each user can be variable according to the data rate. The NARROW FDMA (localized FMDA) accommodated on the frequency block is used by multiple low-speed data users. In addition, when the programming is performed in the time domain and the frequency domain, the frequency blocks can be grouped, which reduces an overload of the pilot channel. In addition, the bandwidth can be changed according to the conditions of the channel, as shown in Figure 18. For example, the frequency band assigned to the system is divided into multiple frequency blocks to perform the assignment. In this case, when the channel conditions are good, multiple frequency blocks, for example, two frequency blocks are assigned (users A, B and C), and when the channel conditions are not good, fewer frequency blocks than the assigned frequency blocks when the channel conditions are good, are assigned (user D). The simple carrier transmission is performed in the frequency band assigned as well, since it improves efficiency as a whole.

With reference to Figures 19A and 19B, the grouping of frequency blocks is explained. When clustering of frequency blocks is not performed, the narrower FDMA (localized FDMA) that is accommodated on the frequency block, or the comb-like spectra are used by multiple low-speed data users as shown in Figure 19A. Like the grouping of frequency blocks, there is a distributed grouping where the discrete frequency blocks form a group and a localized grouping where the frequency blocks form a group, as shown in Figure 19B. As stated above, the overload of the pilot channel for use in CQI measurement can be reduced by grouping the frequency blocks in advance, in order to carry out the programming in the frequency domain. For example, the radio resource allocation determination portion 404 of the receiving apparatus provided in the base station 200, determines the time and frequency allocated to a contention-based channel, eg, a random access channel or channel. reverse packet according to a channel load or the like, and thus imparts the corresponding allocation to each mobile station through the downlink broadcast channel. For example, portion 404 of radio resource allocation determination determines to allocate the radio resources, so that at least a portion of the assigned frequency band is used, when the signal to be transmitted is the channel based on containment. In addition, the radio resource allocation determination portion 404 of the receiving apparatus provided in the base station 200 performs programming depending on the channel conditions and determines the time and frequency allocated for a channel based on programming, for example , the shared data channel or the like, and it imparts to each mobile station through the downlink broadcast channel. The traffic data and control messages of layer 3 are transmitted through the shared data channel. In addition, when communicating through the shared data channel, the H-ARQ (Hybrid Automatic Repeat Request) can be employed. In addition, the radio resource allocation determination portion 404 of the receiving apparatus provided in the base station 200 performs the programming determines the assigned time and frequency for the channel based on programming, for example, a channel through which it is transmitted the information (referred to as a shared control channel), and imparts the corresponding allocation to each mobile station through the downlink broadcast channel. The radio resource allocation control portion 122 controls so that the contention-based channel and the programmed channel are multiplexed. For example, the radio resource allocation control portion 122 controls so that the containment-based channel and the programming-based channel are multiplexed in time, as shown in Figure 20A. In this case, the radio resource allocation control portion 122 can perform an adaptive TTI length control, and adjusts the longer TTI length, which reduces the proportion of the shared control channel occupied over the entire length of the TTI, which reduces the overload of the shared control channel. In addition, the radio resource allocation control portion 122 can control so that the containment-based channel and the programming-based channel are multiplexed in frequency, for example, as shown in Figure 20B. In addition, the radio resource allocation control portion 122 can control so that the contention-based channel and the programming-based channel are multiplexed in time and multiplexed in frequency in a mixed manner. In this case, the radio resource allocation control portion 122 can perform the adaptive TTI length control and adjust the longer TTI length, which reduces the proportion of the shared control channel occupied in the full length of TTI, thereby the overload of the shared control channel is reduced. The generation portion of the frequency domain signal 114 moves each simple carrier signal on the frequency axis, so that the spectrum becomes comb-shaped. For example, when a process corresponding to CRF = 4 is carried out, three zeros are accommodated for each single bearer signal or signal sequence. In addition, the 114 assigns a radio resource to each physical channel according to the information of allocation of radio resources, introduced, and dependent on the physical channel. When the simple bearer method is used in such a way, the value of CRF and the displacement value that displaces each simple bearer signal are changed, and the number of users is changed. The generation portion of the frequency domain signal 114 maps to each of the Q number of the parallel signal sequences, accommodates the signal sequence directly to the frequency component, and allocates the radio resources to each mapped signal. The IFFT portion 116 performs the fast Fourier transformation on the comb-like spectrum obtained by the displacement of each single carrier signal on the frequency axis, and thereby generates a waveform transmission spectrum of the carrier method simple . In addition, the IFFT portion 116 performs the fast inverse Fourier transformation on the multi-carrier signal composed of multiple sub-carriers and performs the modulation based on the OFDM method, thereby generating a waveform transmission spectrum of the method of multiple carriers. The protection interval addition portion (Gl) adds protection intervals to the signals to be transmitted and prepares a symbol of either the OFDM method and the multiple-carrier method. The protection intervals are obtained by replicating a portion of the upper part or the end of a symbol that is to be transmitted. The filter performs a band limitation on the transmission signal. The limited signal in band is transmitted. Next, the receiving apparatus 400 according to this example is explained with reference to Figure 21. The receiving apparatus 400 is provided in the base station, for example, and transmits the downlink channel.

The receiving apparatus 400 according to this example is employed in the aforementioned cellular environment and the local area environment. The receiving apparatus 400 according to this example is capable of receiving a signal transmitted in accordance with the signal carrier method and the multiple bearer method. In addition, the receiving apparatus 400 includes the radio access method determining portion 402 and the radio resource allocation determination portion 404. The radio access method determination portion 402 determines a radio access method that the mobile station 300 is assigned to use in accordance with the environment in which the receiving apparatus 400 is installed. The portion 402 for determining the access method Radio determines the use of the simple bearer method, for example, when the receiving apparatus 400 is installed in the cellular environment, and in this way imparts to the mobile station 300 the use of the simple bearer method. On the other hand, the determination portion of the radio access method 402 determines the use of the multiple-bearer method, for example, when the receiving apparatus 400 is installed in the local area environment, and thus imparts to the mobile station 300 the use of multiple carriers method.

For example, when the base station 200 is installed, the radio access method determination portion 402 determines the radio access method used in accordance with a cell configuration, eg, a cell radius, the presence or absence of neighboring cells, or similar. For example, it is used as a simple carrier when the cell radius is large, whereas the multiple carrier method is used when the cell radius is small. The determination portion of the radio access method 402 imparts the information indicating the access method determined to the mobile stations 300, as control information common to all users. In such a way, the radio access method is determined when the base station is installed, which leads to simplified configuration and control. In addition, the access methods can be switched according to a distance between each user and the base station, or a transmission power margin in each user. For example, when the access methods are switched according to the distance between each user and the base station 200, a propagation loss may be used, for example, as an amount corresponding to the distance between each user and the base station 200. In this case, the mobile station 300 measures the propagation loss in the downlink using a downlink pilot signal receiving power, and in this way imparts information indicating the loss of measured programming to the base station 200 over the uplink. The determination portion of the radio access method 402 determines that a distance between the base station 200 and the mobile station 300 is large when the received value of the propagation loss is greater than a predetermined threshold, determines the use of the carrier method simple, and in this way imparts the information to the mobile stations 300. The determination portion of the radio access method determines that a distance between the base station 200 and the mobile station 300 is small when the value received from the loss of propagation is smaller than a predetermined threshold, determines the use of the simple bearer method, and imparts the information to the mobile stations 300 as common control information for each user. In such a manner, the radio access method is controlled for each mobile station according to the distance between the base station and the mobile stations. Furthermore, when the access methods are switched according to the transmission power margin in each user, "(maximum tolerance transmission energy) - (the current transmission power)" can be used for example, as an indicator of the margin in the transmission power of each user. In this case, the mobile stations impart a value indicating the "maximum tolerance transmission energy - the current transmission energy". The determination portion of the radio access method 402 determines that the transmission power margin is small when the value indicating the "maximum tolerance transmission energy - the current transmission energy" is smaller than a predetermined threshold, and it determines the use of the simple carrier method, which in turn is imparted to the mobile stations 300. On the other hand, the portion 402 of determining the radio access method determines that the transmission energy margin is large when the value which indicates "(maximum tolerance transmission energy) - (the current transmission energy)" is greater than the predetermined threshold, and determines the use of the multi-carrier method, which in turn is imparted to the mobile stations 300. According to the above, the access methods are controlled according to the operation of each mobile station. In addition, the mobile stations 300 can transmit the information indicating the maximum tolerance transmission energy and the information indicating the current transmission energy. Then, the determination portion of the radio access method 402 can calculate "maximum tolerance transmission energy - the current transmission energy" and control the radio access methods according to the calculated value. The radio resource allocation determination portion 404 determines the allocation of the radio recourse to each physical channel, which in turn is imparted to the mobile station 300. In addition, the radio resource allocation determination portion 404 performs programming on each user, and thus reporting the results to the mobile station 300. The radio resource allocation determination portion 404 may allocate a radio resource for a certain time based on a time scale of the length of the radio. Transmission time interval (TTI) of multiple frequency blocks when the time and frequency block is assigned to each physical channel. In addition, the radio resource allocation determination portion 404 performs programming for the shared data channel. The radio resource allocation determination portion 404 performs programming in the time domain in the frequency division multiplex access, and generates the control information, as shown in Figure 13. In this case, multiple blocks of frequency are assigned to a user of fast data speed, which allows each user to use only the frequency blocks assigned in advance. Therefore, the transmission apparatus 100 does not have to receive a pilot channel from other transmitted frequency blocks to thereby allow the receiving apparatus 400 to measure the channel quality indicator (CQI). An optimum bandwidth of the frequency block is 1.25 to 5 MHz, for example. By widening the bandwidth of the frequency block, the diversity effect of multiple users can be increased in the frequency block. When the simple bearer transmission is performed, the bandwidth assigned to each user can be variable according to the data rate. In addition, when a traffic size of a certain user is larger than a load size of the frequency block, a frequency block can be exclusively used by a user. In addition, the bandwidth can be changed according to the channel conditions, as shown in Figure 17. The narrower FDMA (localized FDMA) that is accommodated on the frequency block, can be used by multiple low users. data speed. Namely, the spectrum used by each user is accommodated on the block as described with reference to Figures 2A and 2B. further, the frequency spectrum in the form of a comb used by each user can be distributed over the entire band. Other users use the comb-shaped spectra. The localized FDMA can be mainly used for the shared data channel. In addition, the radio resource allocation determination portion 404 can perform the programming of the time domain and the frequency domain, and generate the control information. In this case, the pilot channel to be transmitted for the purpose of measuring the channel quality indicator (CQI) is transmitted on all frequency blocks, namely on all channel bandwidths. In addition, when a traffic size of a certain user is larger than a load size of the frequency block, a frequency block can be exclusively used by a user. When there are multiple low data rate users, a frequency block is used by multiple users. In this case, the orthogonal frequency spectra, namely the narrower FDMA (localized FDMA) which is accommodated on the frequency block, or the comb-like spectrum (distributed FDMA) is applied to the same frequency block. Namely, as described with reference to Figures 2A and 2B, the spectra used by each user are accommodated on the block in the frequency block. In addition, the frequency spectrum used by each user can be distributed and accommodated in a comb shape on the frequency block, which reduces the interference of multiple users. An optimum bandwidth of the frequency block is 0.3125 to 1.25 MHz, for example. By narrowing the bandwidth of the frequency block and performing the programming of the channel in the frequency domain, the diversity effect of multiple users can be increased in the frequency block. When simple bearer transmission is performed, the bandwidth assigned to each user can be variable according to the data rate. The narrower FDMA (localized FDMA) that is accommodated on the frequency block can be used by multiple low data rate users. In this case, the frequency block can be grouped, which reduces the overload of the pilot channel. In addition, a band, for example, a frequency block can be assigned to multiple users, as shown in Figure 14. In this case, frequency multiplexing using the frequency spectrum in the form of a comb is used. Alternatively, multiple users are multiplexed into a structure or frame in a manner described as follows. The chip information by a certain unit is stored divisionally in time in the TTI. This chip information is used as a unit to change the frequency used for the transmission. As established, multiple users are assigned to a certain band and the transmission is made using the frequency hop. By assigning multiple users to a certain frequency band, interference from other cells (sectors) can be averaged. Therefore, the fluctuations of the interference from other cells (sectors) can be reduced in a temporary way compared to a situation where the users are changed in a certain frequency band to carry out the transmission. With reference to Figures 19A-19B, the grouping of frequency blocks is explained. When clustering of frequency blocks is not performed, the narrower FDMA (localized FDMA) that is narrowly accommodated on the frequency block, or the comb-shaped spectra is used by multiple low-speed data users. Like the grouping of frequency blocks, there is a distributed grouping where the discrete frequency blocks form a group and a localized grouping where the consecutive frequency blocks form a grouped one. As stated above, the overload of the pilot channel for use in a CQI measurement can be reduced by grouping the frequency blocks in advance, in order to carry out the programming in the frequency domain. For example, the radio resource allocation determination portion 404 determines the time and frequency allocated for the contention-based channel, eg, a random access channel or a reservation packet channel, according to a load of channel or the like, and thus imparts the corresponding allocation to each mobile station through the downlink broadcast channel. For example, the radio resource allocation determination portion 404 determines the allocation of the radio resource, so that at least a portion of the assigned frequency band is used, when the signal to be transmitted is the channel based in contention.

In addition, the radio resource allocation determination portion 404 performs programming depending on the conditions of the channel and determines the time and frequency assigned to a programmed channel, for example, the shared data channel or the like, which at its once it is imparted to each mobile station through the downlink broadcast channel. The traffic data and the control message of layer 3 are transmitted through the shared data channel. For example, the radio resource allocation determination portion 404 groups the channels according to the channel conditions, for example, the CQI measurement result to perform the assignment, which can reduce the overload of the pilot channel. In addition, when communications are made through the shared data channel, an H-ARQ (Hybrid Automatic Repeat Request) may be employed. In addition, the radio resource allocation determination portion 404 performs programming, and determines the time and frequency assigned to the shared control channel, which in turn are imparted to each mobile station through the link broadcast channel. descending Next, with reference to Figure 22, a configuration of the receiver that changes the bands according to the channel conditions to perform the assignment is explained. A receiver 400 has the same configuration as the reception apparatus explained with reference to Figure 21. The radio resource allocation determination portion 404 of the receiver 400 comprises a reception feature measurement portion 406, a classification portion 408. connected to the portion 406 for measuring reception characteristics, a portion 410 of frequency block assignment connected to the classification portion 408, a portion 412 for determining the reception energy connected to the portion 410 of frequency block assignment , and a portion 414 of MCS determination connected to the portion 412 of determining the reception energy. The portion 406 for measuring reception characteristics measures a reception characteristic, for example, the SINR received in each frequency block, for all users. All users transmit pilot signals in the entire band. The reception characteristics measuring portion 406 measures the reception conditions, for example, the SINR received in each band. In addition, when users transmit the pilot signals using a part of the frequency band in the entire frequency band (system bandwidth), the SINR received in each allocation unit in the frequency band determined in advance, for example , in each block of frequency is measured, as shown in Figure 23A. Namely, the measurement portion 406 of reception characteristics measures the reception characteristics of the transmitted pilot signals using the frequency band assignment unit determined in advance as a measurement unit. When the users transmit the pilot signals using a part of the frequency band in the entire frequency band, the reception feature measurement portion 406 can measure the reception conditions in the frequency band part, as shown in FIG. Figure 23B. Namely, the measurement portion 406 of reception characteristics measures the reception characteristics of the pilot signals transmitted using the allocation unit, for example, the transmission frequency of the pilot signal as a measurement unit. The ranking portion 408 determines the priorities according to the measured reception characteristic and classifies the priorities in a predetermined order, for example, in the order of the highest received SINR, to thereby generate a classification table. In addition, the classification portion 408 can generate the classification table according to at least one of a receiving condition of the pilot signal transmitted from each mobile station, the reception condition at the base station being measured (in other words, a reception energy measured in the receiving apparatus with respect to the channel condition measurement signal), a waiting time and a data type that it will be transmitted from each mobile station, and the maximum transmission power of each mobile station. As a result, a mobile station to which a frequency band is to be assigned is determined for each frequency assignment unit. The frequency block assignment portion 410 allocates a frequency block according to the generated classification table. For example, the frequency block allocation portion 410 performs tentative allocation of the frequency block to be assigned to a high priority user. In addition, the frequency block allocation portion 410 allocates the tentatively assigned block and the frequency block adjacent to the user of the highest priority. In addition, the frequency block allocation portion 410 classifies the priorities in the highest order, excluding the corresponding user priorities and the frequency blocks that have already been assigned, to reclassify the table and repeat the same procedures. In such a manner, the continuous frequency bands are assigned to an apparatus according to the reception characteristics for each transmission apparatus. In this case, the frequency block allocation portion 410 allocates a frequency band within a range of the transmission frequency of the pilot signal, as shown in Figure 24A. In addition, the frequency block allocation portion 410 may allocate a frequency band per unit of assignment of, for example, an integral multiple of the frequency bands, as shown in Figure 24B. Further, when the mobile station transmits the pilot signal for each frequency band allocation unit based on the frequency hop, the frequency block allocation portion 410 can perform the programming on the band in which the pilot signal is transmitted. , and assign the data channels, as shown in Figure 25A. In addition, the band in which the pilot signal is transmitted is assigned to deviate over time. In this case, the frequency block allocation portion 410 determines the data channel for each band where the pilot signal has been transmitted. In this case, the programming cycle becomes longer. For example, at time t, all mobile stations, for example, MSI, MS2, MS3 and MS4 transmit the pilot signals in the same band. The frequency block allocation portion 410 performs programming between the mobile stations that transmit the pilot signals in the same band. In this case, the programming is performed between the mobile stations MSI, MS2, MS3 and MS4, and the data channel is assigned to the mobile station MS3. At the time (t + 1), the mobile stations MSI, MS2, MS3 and MS4 transmit the pilot signals in different bands of the bands in which the pilot signals have been transmitted at time t. For example, mobile stations MSI, MS2, MS3 and MS4 transmit the pilot signals in the band adjacent to the bands in which the pilot signals have been transmitted at time t. The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals on the same band. In this case, the programming is performed between the mobile stations MSI, MS2, MS3 and MS4, and the data channel is assigned to the mobile station MS2. At the time (t + 2), the mobile stations MSI, MS2, MS3 and MS4 transmit the pilot signals in different bands of the bands in which pilot signals have been transmitted at time (T + 1). For example, the mobile stations MSI, MS2, MS3 and MS4 transmit the pilot signals in the bands adjacent to the bands in which the pilot signals have been transmitted at time (t-1). The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals on the same band. In this case, the programming is performed on the mobile stations MSI, MS2, MS3 and MS4, and the data channel is assigned to the mobile station MS2. Then, the allocation of the data channel is repeated. Incidentally, when each mobile station independently transmits the pilot signal based on the frequency hop, the frequency block allocation portion 410 can perform the programming for each frequency assignment unit on the mobile stations transmitting the pilot signals in the bands, to assign the data channel as well. For example, a band adjacent to the band that has already been assigned is assigned to a certain mobile station. For example, at time t, mobile stations, for example, MS3, MS4, MS5 and MS6 transmit the pilot signals in different bands; the mobile station MSI transmits the pilot signal in the bands in which the mobile stations MS3 and MS4 transmit the pilot signals; and the mobile station MS2 transmits the pilot signal in the bands in which the mobile stations MS5 and MS6 transmit the pilot signals. The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals in corresponding bands. The frequency block allocation portion 410 performs programming for band allocation unit. For example, the frequency block allocation portion 410 performs programming on the mobile stations MSI and MS3 and assigns the data channel to the mobile station MSI; performs programming on the mobile stations MSI and MS2 and assigns the data channel to the mobile station MS4; performs programming on the mobile stations MS2 and MS5 and assigns the data channel to the mobile station MS5; and performs programming on the mobile stations MS2 and MS6 and assigns the data channel to the mobile station MS2. At the time (t + 1), the mobile stations, for example, MS3, MS4, MS5 and MS6 transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the bands where the pilot signals were transmitted at time t. In addition, mobile stations, for example, MSI and MS2, transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the bands in which the pilot signals have been transmitted at time t. The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals in the corresponding bands. The frequency block allocation portion 410 performs programming for each band allocation unit. For example, the frequency block allocation portion 410 performs programming on the mobile stations MS2 and MS6 and assigns the data channel to the mobile station MS2; performs programming on the mobile stations MS2 and MS3 and assigns the data channel to the mobile station MS2; performs programming on the mobile stations MSI and MS4 and assigns the data channel to the mobile station MS4; and performs programming on the mobile stations MSI and MS5, and assigns the data channel to the mobile station MS5. At time (t + 2), mobile stations for example, MS3, MS4, MS5 and MS6 transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the bands in which the pilot signals have been transmitted at time (t + 1). In addition, the mobile stations Ml and M2 transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the bands where the pilot signals have been transmitted at time (t + 1). The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals in each band. The frequency block allocation portion 410 performs programming for each band allocation unit. For example, the frequency block allocation portion 410 performs programming on the mobile stations MSI and MS5 and assigns the data channel to the mobile station MS5; performs programming on the mobile stations MSI and MS6 and assigns the data channel to the mobile station MS6; performs programming on the mobile stations MS2 and MS3 and assigns the data channel to the mobile station MS2; and performs programming on the mobile stations MS2 and MS4 and assigns the data channel to the mobile station MS4. Further, when each mobile station independently transmits the pilot signal based on the frequency hop, the frequency block allocation portion 410 may allocate the data channel in each band allocation unit using the reception quality based as the characteristic. reception (reception quality) in the case of ^ the band in which the pilot signals are not transmitted, shown in Figure 25C. In this case, there may be multiple mobile stations that transmit the pilot signals in the same frequency band. For example, at time t, mobile stations, for example, MSI, MS2, MS3 and MS4 transmit the pilot signals in different bands.

The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals in the corresponding band. The frequency block allocation portion 410 performs programming for each band allocation unit. At the time (t + 1), the mobile stations, for example, MSI, MS2, MS3 and MS4, transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the bands in which the pilot signals have been transmitted at time t. The frequency block allocation portion 410 performs programming between the mobile stations that transmit the pilot signals in corresponding bands. The frequency block allocation portion 410 performs programming for each band allocation unit using the reception quality passed as the reception characteristic (reception quality) in the case of the band in which the pilot signals are not transmitted. . At the time (t + 2), the mobile stations, for example, MSI, MS2, MS3 and MS4, transmit the pilot signals in different bands. For example, the pilot signals are transmitted in bands adjacent to the band in which the pilot signals have been transmitted at time (t + 1).

The frequency block allocation portion 410 performs programming on the mobile stations that transmit the pilot signals in corresponding bands. The frequency block allocation portion 410 performs programming for each band allocation unit using the reception quality passed as the reception characteristic (reception quality) in the case of the band in which the pilot signals are not transmitted. . When it is assumed that there are small fluctuations in the channel conditions and the band in which the pilot signal is transmitted is not changed, if the channel conditions are deteriorated, the reception characteristic of the band remains impaired. Therefore, by changing the bands in which the pilot signals are transmitted, the reception characteristic can be improved. In addition, when the data channel is assigned to the frequency assignment band, the band that has once been assigned is not changed, as long as the reception conditions change to a certain degree, as shown in Figure 26. Namely, once the frequency block allocation portion 410 allocates a frequency band, the frequency block allocation portion 410 continues to continuously allocate the frequency band until the energy of reception of the measurement signal of the channel conditions in the frequency band in the receiving apparatus, exceeds a predetermined threshold in advance. For example, when the conditions of the channel in the allocated band change to exceed the predetermined threshold, the band is released and reallocation is performed taking into account the channel conditions of each mobile station. With this, interference from other cells (sectors) can be reduced. The receiver 400 changes the modulation methods depending on the reception conditions before the application of AMC. Changes in the conditions after the modulation method or the like are determined by the normal deteriorated reception. Namely, reception conditions in the uplink are interfered with by other cells (sectors), especially other nearby users. For example, when the A330 mobile station? is transmitting while the mobile station D3004 which exists in the adjacent sector 2503 in Figure 15 is transmitting, the mobile station A300? it is influenced by the interference coming from the mobile station D3004. When the A300 mobile station? is transmitting while the mobile station B3002 that exists in the adjacent sector 2503 is transmitting, the mobile station A300? it is interfered with by the mobile station B300. The A300 mobile station? determines a method of modulation depending on the proportion of the required radio waves on the radio waves of interference. When the frequency band assigned to the mobile station B3002 is switched to the mobile station C3004, the amount of interference increases. While the A300 mobile station? determines the MCS taking into account the interference signals from the mobile station B3002, if the frequency assignment is suddenly performed so that the frequency band is switched to the C3004, the amount of the interference from the adjacent sectors is increased , which makes it impossible for the reception station to perform the reception by the modulation method first determined. In order to avoid such a situation, the band that has been assigned once can not be changed, as long as the changes in the reception conditions do not become of a certain level or more. When the reception conditions become of a certain level or more, for example, of a certain threshold, the band is released and the reallocation is made according to the channel conditions of each mobile station. The portion 412 for determining the reception energy assigns the uplink transmission energy to the mobile station to which the frequency band is assigned. In this case, the uplink transmission energy is assigned to the mobile station (transmitter) to which the frequency band is assigned according to the assigned frequency bandwidth. For example, the maximum energy with which the mobile (transmitting) station can transmit has been determined. A situation where the transmission power for the allocated band is, for example, X as shown in Figure 27A has been described below. If the assigned band is widened, for example, doubled, the transmission energy is halved to be X / 2, as shown in Figure 27B. The transmission energy is determined according to the bandwidth allocated in such a way. The portion 412 for determining the reception energy transmits the programming result and the information indicating the transmission energy to the transmitter. This adjustment of information is introduced to the radio resource allocation control portion 122. For example, when the transmission energy for a certain allocation band has a maximum value in X, if the assigned band is widened, for example, doubled, the peak of the transmission energy is halved to be X / 2 . The portion 412 for determining the reception energy transmits the programming result and the information indicating the transmission energy to the transmitter. This adjustment of information is introduced to the radio resource allocation control portion 122. As a result, the mobile station performs uplink transmission with the maximum transmission power in the assigned frequency band. By convergence of energy in a certain band as stated above, the energy of the required radio waves can be increased. Especially, when the power converges in a certain band to thus perform the transmission by an existing mobile station further away from the base station (receiving apparatus), the base station can receive a signal with a higher energy, thereby improving the quality of reception. The portion 412 for determining the reception energy can measure the interference energy in the band to be allocated, and assign the transmission energy using the interference energy, in such a way that the energy proportion of the waves of radios required on the interference energy, it becomes a predetermined value. In this case, the transmission energy that produces the intended ratio of the required radio wave energy over the interference energy, can be converted into the transmitting energy or more which the mobile station can send out. In this case, the transmission energy that the mobile station can send out is assigned. On the other hand, when the transmission energy that produces the intended ratio of the energy of the required radio waves to the interference energy is lower than or equal to the transmission energy with which the mobile station can transmit, the transmission energy that produces the intended proportion of the energy of the required radio waves on the interference energy, is assigned. In this way, the transmission energy can be controlled according to the reception quality in the base station. In addition, the mobile station performs the transmission of uplink signal with the maximum transmission power in the assigned frequency band. The base station can realize the reception of a higher energy signal, thereby improving the quality of the reception. In addition, with regard to transmission power, the mobile station can perform the uplink transmission with a constant transmission power density, notwithstanding the assigned frequency bandwidth. For example, the radio resource allocation control portion 122 performs transmission with the transmission power according to a predetermined frequency bandwidth, even when a narrower frequency band than the predetermined frequency band is assigned, as shown in Figures 28A and 28B. Since the transmission is performed at a constant transmission power per band as stated above, the interference with another cell (sectors) may be less influential. The transmission energy can be changed depending on the position of the mobile station. Namely, this can be determined if the uplink transmission is performed with the maximum transmission power in the assigned frequency band, or with a constant transmission power density, notwithstanding the assigned frequency band. Then, the transmission energy can be determined by the determined method and the information indicating the transmission energy can be imparted. The base station may assign a modulation method and an error correction code rate in the uplink transmission to the mobile station to which the frequency band is assigned. The modulation method and the speed of the error correction code can be determined according to the proportion of the required radio wave energy over the interference energy in the MCS determination portion 414 of the base station. Here, an instantaneous value or an average value of the energy of the required radio waves and interference can be used. For example, when the transmission apparatus to which the frequency band is assigned transmits a signal according to the assigned transmission power and the energy of reception of the measurement signal of the channel conditions, either the instantaneous value is used. or the average value in accordance with the transmission energy and the interference energy in the receiving apparatus which receives the signal transmitted by the transmission apparatus, the transmission energy and the interference energy are estimated at the assigned frequency. Then, the modulation method and the error correction code rate are determined according to the ratio of the reception energy to the interference energy. A situation is described where the mobile station performs uplink transmission with the maximum transmission power in the assigned frequency band, for example. The transfer energy fluctuates greatly in the uplink. When the modulation method is determined according to the instantaneous reception energy, the level of interference energy fluctuates depending on the time required to start the transmission. Therefore, when such transmission is performed, the average values of the reception energy, the required radio waves, and the interference energy are used. Then, a situation is described where the uplink transmission with a constant transmission density, however, of the assigned frequency band is performed. When the control is performed under such a situation where the fluctuations of the interference energy are small, the instantaneous values of the reception energy, the required radio waves, and the interference energy are used. When the MCS determination portion 414 allocates the MCS when the mobile station is allowed to perform the transmission, transmits the data channel, the MCS determination portion 414 can assign the MCS according to the quality of reception of the signal measured pilot for each frequency assignment unit in the assigned band, when the received SINR is measured for each frequency allocation unit by the reception characteristics measurement portion 406 as shown in Figure 29. For example, the SINR received measure for each allocation unit, is used and in this way the MCS is assigned according to at least one of the average SINR, the highest SINR and the lowest SINR. In addition, a receiver that performs the allocation to thereby change a bandwidth according to the channel conditions, can be configured as shown in Figure 30. A receiver 400 has substantially the same configuration as the receiver explained with reference to the Figure 21, and is different from the receiver explained with reference to Figures 2A-2B in that the portion 416 of assignment of the pilot signal, connected to the portion 406 for measuring reception characteristics, is provided. The allocation portion 416 of the pilot signal receives at least one of the information indicating the required (maximum) transmission frequency bandwidth of the data channel transmitted from the mobile station, the information indicating the amount of data that is going to be transmitted, and the information that indicates the data rate. In addition, the pilot signal portion 416 receives the information indicating the required (maximum) transmission bandwidth of the pilot signal from the mobile station. The assignment portion 416 of the pilot signal allocates a transmission bandwidth of the pilot signal to the mobile station. For example, the allocation portion 416 of the pilot signal determines the transmission bandwidth and the center frequency of the pilot signal according to the information indicating the required (maximum) transmission bandwidth of the pilot signal for each mobile station, and transmits the information indicating the determined transmission bandwidth and the central frequency of the pilot signal to the corresponding mobile stations. In addition, the portion 416 of assigning the pilot signal can impart information indicating the determined transmission bandwidth and the center frequency of the pilot signal to the corresponding transmission apparatuses by transmitting the ID of the frequency block. In this case, the pilot signal allocation portion 416 can allocate multiple frequency blocks. For example, the pilot signal allocation portion 416 allocates a narrower bandwidth than the maximum bandwidth required by the mobile station (bandwidth required (maximum)) when it is determined that the quality of reception of the signal pilot is insufficient even when the mobile station transmits the pilot signal in the required (maximum) bandwidth, due to a large distance to the base station. For example, the pilot signal allocation portion 416 allocates the transmission bandwidth of the pilot signal according to the maximum transmission power of each mobile station and a propagation loss between the base station and each mobile station. In addition, the allocation portion 416 of the pilot signal allocates the transmission bandwidth and the central frequency of the pilot signal of each mobile station, so that the deviation of the reception energy of the pilot signal measured in the domain of frequency in the base station, is reduced or unprovoked, when the transmission bandwidth and the central frequency of the pilot signal of each mobile station are assigned, as shown in Figure 32. For example, the pilot signal portion 416 determines in advance a reference value indicating the deviation of the receive power of each pilot signal and determines the transmission bandwidth and the central frequency of the pilot signal, so that the deviation is maintained at the reference value or lower. In this case, the allocation portion 416 of the pilot signal calculates a total reception energy of the pilot signal from the mobile stations in the uplink in the base station, and allocates the transmission bandwidth and the center frequency of the pilot signal of each mobile station, so that the deviation of the transmission bandwidth becomes smaller in the frequency domain. Further, when the pilot signal assignment portion 416 allows the mobile stations to transmit the pilot signal based on the IFDMA method, the pilot signal allocation portion 416 determines the frequency bandwidth and a repetition factor of the pilot signal of each mobile station, so that each frequency component is used without excess or deficiency, as shown in Figure 33A. Namely, an amount of the frequency offset is determined and the transmission is made based on the frequency division multiplexing method. In this case, a displacement of 5 frequencies is given, so that there is no band shared by the same user. For example, the allocation portion 416 of the pilot signal allocates the transmission bandwidth and the center frequency of the pilot signal transmitted by each mobile station according to a number Remainder of the repetition factor. In this case, the pilot signal allocation portion 416 allocates and imparts the repetition factor, the frequency bandwidth and the center frequency of the pilot signal. In addition, the portion 416 of signal assignment The pilot assigns the transmission band of the measurement signal of the channel conditions, so that the number of mobile stations transmitting the channel measurement signal does not vary in each frequency band. For example, the allocation portion 416 of the pilot signal assigns the band transmitting the channel measurement signal to each mobile station, starting from the mobile stations / that have a wider transmission band. In this case, the transmission bandwidth is, for example, 2n times the minimum transmission bandwidth. 25 A situation is explained here where the numbers of mobile stations that have transmission bandwidth of 5 MHz, 2.5 MHz and 1.25 MHz are N5, N2.5, and Ni.25 in the bandwidth of the 10 MHz system, for example. In this case, the minimum transmission bandwidth, for example, the bandwidth of the frequency block, is assumed to be 1.25 MHz. (1) Are random numbers given to the variables f5 MHz, F2.5 MHz and f? .25 MHz. Here, random numbers are integers. (2) The ID of the frequency block and 4 blocks (= 5 / 1.25 blocks of ((f5 MHz + n5) mod (10/5) x (10/5)) are assigned to the n5-th mobile station that has the transmission bandwidth of 5 MHz. (3 ) The ID of the frequency block and 2 blocks (= 2.5 / 1.25 blocks of ((f5 MHz + N5 + n2.5) mod (10/5) x (10/5) + (F2.5 MHz + n2.5) mod (5 / 2.5) x (5 / 2.5)) are assigned to the n25-th mobile station that has the 2.5 MHz transmission bandwidth. (4) The ID of the block of frequency and 1 block (= 1.25 / 1.25 blocks of ((f5 MHz + N5 + N2.5 + ni.25) mod (10/5) x (10/5) + (F2.5 MHz + N2. 5 + ni.25) mod (5 / 2.5) x (5 / 2.5) + (F1.25 MHz + N2.5 + Ni.25) mod (2.5 / 1.25) x (2.5 / 1.25)) are assigned to the n25-th mobile station having the transmission bandwidth of 2.5 MHz. For example, in the case of N5 = 3, N25 = 3, N? .25 = 4, f5 MHz, f2.5 MHz, and f ?. 25 MHz = 0, the band allocation in one sector is performed in a mobile station per mobile station base, from the mobile stations having a wider bandwidth, as shown in Figure 33 B. The portion 416 The assignment of the pilot signal performs the aforementioned assignment to a predetermined cycle, since the transmission bandwidth and the number of the mobile stations change n due to a change in the propagation loss due to the movement of a mobile station and / or over load. When the mobile station is transmitting the pilot signal using the required (maximum) transmit frequency bandwidth, the receiving feature measurement portion 406 measures the received SINR using the required frequency bandwidth (allocation bandwidth) required) of the data channel as a measurement unit, as shown in Figure 34. The frequency block allocation portion 410 allocates the frequency bands to each mobile station within a range of the signal transmission band. pilot according to the information indicating the received SINR, measurement, the transmission band of the pilot signal, and the desired frequency bandwidth of the data channel. In this case, the frequency block allocation portion 410 may carry out the assignment using the frequency assignment unit determined in advance, for example, the frequency block as a unit. The MCS determining portion 414 assigns the MCS to the mobile station to which the transmission is allowed according to the quality of reception of the pilot signal in the assigned band, as shown in Figure 35. Next, with reference to Figure 36, the operations of the transmission apparatus 100 according to this example are explained. The base station 200 determines the radio access method used by the mobile station 300 and imparts the method to the mobile station 300. First, the information indicating the radio access method is received (step S1302). Next, the switching portion 106 determines whether the radio access method indicating information indicates the simple bearer method (step S1304). When the received information indicating the radio access method indicates the simple bearer method (step S1304: SI), the switching portion 106 changes to the simple bearer method. Namely, the switching portion 106 outputs the sequence of the input spreading chip to the FFT portion 108. Next, the generation portion of the frequency domain signal 114 determines whether or not the transmission data is assigned to a channel based on containment (step S1308). When the transmission data is assigned to the contention-based channel (step S1308: YES), the frequency domain signal generation portion 114 allocates a radio resource to the contention-based channel according to the resource allocation information. radio input. The transmission data to which the radio resources are allocated is transmitted (step S1310). On the other hand, when the transmission data is not the containment-based channel, or the programming-based channel (step S1308: NO), the frequency domain signal generation portion 114 allocates the radio resource to the channel based in programming, according to the radio resource allocation information entered. The transmission data to which the radio resource is assigned is transmitted (step S1312). When the information received indicating the radio access method, indicates the method of multiple carriers (step S1304: NO), the switching portion 106 changes to the multiple carrier method. Namely, the switching portion 106 outputs the sequence of the input spreading chip to the S / P conversion portion 110 (step S1314).

Next, the generation portion of the frequency domain signal 114 determines whether the transmission data is assigned to a channel based on containment (S1316). When the transmission data is assigned to the containment-based channel (step S1316: YES), the frequency domain signal generation portion 114 allocates the radio resource to the contention-based channel, according to the allocation information of radio resource, introduced. The transmission data to which the radio resources are assigned is transmitted (step S1318). On the other hand, when the transmission data is not assigned to the contention-based channel, or the programming-based channel (step S1316: NO), the frequency domain signal generation portion 114 allocates the radio resource to the channel based on programming, according to the radio frequency assignment information, entered. The transmission data to which the radio resource is assigned is transmitted (step S1320). Next, with reference to Figure 37, the operations of the receiving apparatus 400 according to this example are explained. First, the radio access method determining portion 402 determines the radio access method used by the mobile station 300. Next, a situation is explained where the radio access method determining portion 402 determines the carrier method simple as the radio access method used by the mobile station 300. The reception feature measurement portion 406 measures the priority of each frequency block, for example, the received SINR for all users (step S2602). The priorities corresponding to the number of the frequency blocks are obtained for each user. Next, the classification portion 408 classifies the priorities of the "(number of users) x (the number of the frequency blocks)" in higher order, and associates the users with the frequency blocks, so as to generate a table of classification (step S2604). When all users transmit the pilot channels using the full band, the number of classifications in the ranking table is equal to the number of users as many times the number of the frequency blocks. When the users transmit the pilot channels using different frequency bands, there is no classification corresponding to the frequency block in which the users do not transmit the pilot channels. For example, when a certain user transmits the pilot channel using five frequency blocks of the 8 frequency blocks, there are no classifications corresponding to the 3 remaining frequency blocks in the classification table. Next, the frequency block allocation portion 410 performs the tentative assignment of the frequency blocks to the users, on a user-by-user basis according to the highest order of priority (step S2606). The frequency block allocation portion 410 refers to the classification table and assigns the corresponding frequency blocks to the users in order of highest priority. For example, user A is rated with number 1 and the frequency block corresponding to user A is 4, according to the classification table. In this case, "Al" indicates that user A and classification # 1 is written in frequency block 4. Similarly, "A2" indicates the user and classification # 2 is written in frequency block 5. Being repeated the same procedures, the tentative assignment is made. Next, the frequency block allocation portion 410 realizes allocation of the continuous frequency blocks among the frequency blocks tentatively assigned to the highest priority user (step S2608). Frequency blocks 3 to 5 and frequency block 8 are assigned to user A. However, the band that includes the highest classification frequency block is assigned due to the simple carrier method. In other words, blocks 3 to 5 are assigned. Then the frequency block allocation portion 410 determines whether all frequency blocks are allocated, or all users are assigned (step S2610). When all frequency blocks are assigned or all users are assigned (step S2610: YES), the transmission power or power and the MCS are determined for all users to whom the frequency blocks are assigned (step S2614). On the other hand, when all the frequency blocks or all the users are not assigned (step S2610: NO), the frequency block allocation portion 410 classifies priorities in order of priority, except the priority of the users to which the frequency blocks are assigned (step S2612), and return to step S2606. In this case, since the blocks of frequency 3 to have been assigned to user A, the previous procedures are repeated, excluding blocks 3 to 5. In this way, bands that have good channel conditions are assigned to each user. It is not possible to assign discrete frequency blocks but continuous frequency blocks to each user. Next, with reference to Figure 38, the operations of another receiving apparatus 400 according to this example are explained. Specifically, the operations of the receiving apparatus 400 explained with reference to Figure 30 are explained. As stated above, the receiving apparatus 400 is included in the base station and the transmission apparatus 100 is included in the mobile station. First, the portion 402 of determining the radio access method determines a radio access method used by the mobile station 300. In the following, a situation is explained where the portion 402 for determining the radio access method determines the method of the simple carrier as the radio access method used by the mobile station 300. The pilot channel generation portion transmits to a mobile station at least one of the information indicating the required (maximum) transmission frequency bandwidth of the data channel to the base station, information indicating a quantity of the data to be transmitted, and information indicating a data rate. In addition, the generation portion of the pilot channel imparts information indicating the maximum transmission bandwidth required of the pilot signal (step S3802). The allocation portion 416 of the pilot signal determines the frequency bandwidth and the center frequency of the pilot signal transmitted by the mobile station, according to the information indicating the maximum transmission bandwidth required of the pilot signal ( step S3804), and imparts information indicating the determined frequency bandwidth and the center frequency of the pilot signal to the mobile station (step S3806). In addition, the portion 416 of assigning the pilot signal can impart information indicating the determined center frequency and the transmission bandwidth of the pilot signal to the corresponding transmission apparatuses, by transmitting an ID of the frequency block. In this case, the pilot signal allocation portion 416 can allocate multiple frequency blocks. For example, the allocation portion 416 of the pilot signal allocates the transmission bandwidth according to the maximum transmission power of each mobile station and a propagation loss between the base station and each mobile station. The generation portion of the pilot channel transmits the pilot signal according to the information indicating the central frequency imparted and the frequency bandwidth (step S3808). In this case, the generating portion of the pilot signal can transmit the pilot signal based on the frequency hop. The reception characteristic measuring portion 406 measures the SINR received in the pilot signal. In addition, the frequency block allocation portion 410 determines a mobile station to which a frequency band is assigned in accordance with the received SINR of the pilot signal. In addition, the determination portion 414 of the MCS determines the MCS for the mobile station to which the frequency band is assigned and which is allowed to perform the transmission (step S3810). Here, the portion 412 of determining the reception energy can determine the transmission energy for the mobile station to which the frequency band is assigned and which is allowed to carry out the transmission. The radio resource allocation determination portion 404 imparts to the mobile station that is allowed to perform the transmission, the information indicating the data channel allocation band (piece of information, frequency blocks) and the MCS that is going to be used (step S3812). The information indicating the allocation band of the data channel, which is transmitted from the base station, is input to the radio resource allocation control portion 122, and the MCS information is input to the dispersion portion 102 and of channel code.

Dispersion portion 102 and channel code performs channel coding by applying the error correction code, such as the turbo code or the convolution code to the binary information sequence entered in accordance with the MCS information entered. , and in this way modulates the data encoded by channel. The generation portion of the frequency domain signal 114 determines the size of the data according to the allocated bandwidth. The information indicating the user ID, the MCS, the new / retransmission discriminator, and the data size is multiplexed on the control channel. As a result, the transmission frame is generated (step S3814). Next, the mobile station transmits the data channel (step S3816). The data channel transmitted from the mobile station is demodulated and decoded in the base station (step S3818). The base station transmits the recognition / non-recognition (ACK / NACK) according to the result of the demodulation and the decoding of the data channel. This international patent application is based on the Japanese Priority Requests Nos. 2005-105492, 2005-174394, 2005-241899, 2005-317567, 2006-031749, filed on March 31, 2005, filed on June 14, 2005, filed on August 23, 2005, filed on October 31, 2005, filed on February 8, 2006, respectively, with the Japanese Patent Office, the complete contents of which are incorporated by reference herein.
