On the other hand, in a wireless communication system such as LTE, the base station performs a disturbance process on the transmission data (for example, Non-Patent Documents 3 and 4 below). For example, the base station adds the transmitted data b(0), .. _, b(Mbit-l) and the scrambling code c(i), and calculates the remainder of the "2" (Modulo) to perform the scrambling. That is, [Number 1] ^(0 = (b(i) + c(/)) mod2 Here, the scrambling code c(i) is a Gold's code of length "31", which is obtained by the following generator polynomial.

CoMP communication control unit 220, and outputs it to the code modulation unit 213. The code modulation unit 213 performs coding and modulation processing on the radio channel quality information, the connection request signal, the CoMP communication request signal, and the like. The transmission radio unit 214 controls the transmission power such as the radio channel quality information such as the code, and outputs it to the antenna 2 as a radio signal (M. The radio channel quality information or the like is transmitted as a radio signal to the base station 100-1. 〇〇122 〇<Configuration Example of Scrambling Code Creation Unit> Next, the scrambling code creation unit of the main base station 100_b from the base station 1〇〇_2 scrambling code creation unit U2 and the terminal unit 200 A configuration example of the 207 is shown in Fig. 6. Fig. 6 is a view showing a configuration example of the scrambling code creation units 112 and 2, and is a known gold code generator. The σ scrambling code creation units 112 and 207 have first and second temporary Memory (or flip-flop) 丨12-1, 112-3, first to third exclusive logic and circuits 112-2, 112 4, 112-5. '...scrambling code generation unit m, 2〇7 generation length The "G" code (or scrambling code) of "31", the output is the scrambling code e(8). The life of the scrambling code e(8) is expressed by the above number 2 to 4. [ltrassing operation example> Next, The operation example of the first embodiment will be described. Fig. 7 and Fig. 8 are flowcharts showing an example of the operation. In addition, the terminal 200 is located in the same manner as the main beauty. 201044808 The station 100-1 and the area from which the base station 100-2 is communicatively connected. First, the main base station 100-1 notifies the terminal device 200 of the cell information, etc. (S10). The cell information notified by the main base station 100-1 The cell information (cell number, terminal, and slot number) created by the cell information signal generating unit 106 may be included. Next, the master base station 100-1 transmits a pilot signal (S11). For example, the pilot signal is The transmitting wireless unit 115 of the primary base station 100-1 generates the channel. The terminal 200 selects the cell to be communicated (S12)' to set the line (si3) with the selected cell based on the received pilot signal or the like. For example, 'the received power measuring unit 21 of the terminal 200 measures the received power of the pilot signal', and the line connection control unit 211 determines the connection of the line, and selects the cell (for example, the master base station 100-1). Then, the connection request The signal generation unit 212 creates a connection request signal 'to be transmitted to the main base station 1〇〇_ι, and sets the line. The terminal 200 is initially connected to the main base station 1〇〇_1. Then the 'terminal 200 measures and the main Base station (7) The quality of the wireless line (for example, C()I) (S14) transmits the wireless channel quality information to the primary base station l〇〇-l (S15). For example, the calculation unit 204 of the terminal 200 receives the signal. Measuring the quality of the wireless line 'The wireless line quality information creation unit 2〇5 creates the wireless line quality information, and transmits the information to the primary base station 1〇〇_1. Then, the primary base station 100-1 performs the line according to the wireless line quality information. (S16), for example, the main base station ιοο-丨 scheduler 11 performs scheduling based on the wireless quality information extracted by the wireless quality information extracting unit 109. Next, the master base station 100-1 performs transmission signal processing (S17). For example, the 'encoding modulation unit 114 reads the transmission 201044808 data stored in the transmission data buffer 113, and performs processing such as encoding by the coding rate of the scheduler 110 schedule. Further, the control signal including the schedule information created by the control signal creation unit lu is also subjected to processing such as encoding in the code modulation unit 114. Then, the master base station 100-1 transmits the control signal and the transmission data to the terminal 200 (S18, S19). When the terminal 200 receives the control signal and transmits the data, it performs reception signal processing (S20). For example, the terminal setting control unit 2〇9 controls the receiving wireless unit 2〇2 and the demodulation and decoding unit 203 to perform demodulation, decoding, and the like based on the schedule information included in the received control signal. Next, the terminal device 200 receives the cell information and the like signal (S21, S22) notified from the base station 1_2. Then, the terminal 2 selects the base station 100-2 as the connection base station (S23), and sets a line between the base station 1 and the base station (S24). Next, a process for performing CoMP transmission is performed between the terminal 200 and the base stations 1〇〇_1 and 1〇〇_2. First, the terminal 2 receives the pilot signals from the master base station 100-1 and the slave base station 100-2 (S25, S26), and measures the channel quality of each wireless line (S27). For example, the calculation unit 204 of the terminal unit 2 measures the quality of each wireless line. In addition, at this time, the signal indicating the primary base station 100-1 and the base station 1〇〇-2 may be the cell number of the primary base station 100-1 and the base station 100-2. The original cell number is based on the different indicator signals. Then, the terminal 200 transmits the measured radio channel qualities to the slave base station 100-2 and the master base station i〇〇-i (s28, S30). For example, the wireless channel quality information creating unit 205 creates each wireless line quality resource 17 201044808 to transmit the information. The base station 100-2 transmits the radio channel quality information transmitted from the terminal 200 to the main base station 100-1 (S29). For example, the wireless channel quality information extracting unit 109 from the base station 〇〇2 transmits the wireless channel quality to the extracted terminal device 2 to the primary base station 100-1. Next, the main base station 100-1 determines whether or not C〇MP transmission is possible (S31). For example, when the control unit 108 of the master base station 100-1 determines that the radio channel quality of the base station 100-2 and the radio channel quality extracted by the CoMP communication request signal extracting unit 1〇7 are both above the threshold value, the determination can be made. c〇MP communication. The threshold value compared with the radio channel quality of the primary base station 100-1 and the threshold value compared with the radio channel quality from the base station 100-2 may be the same or different. Further, when the control unit 108 determines that the c〇MP transmission cannot be performed, the control unit 108 ends the processing of the consecutive application. Then, the terminal 200 transmits a CoMP transmission execution request to the slave base station 100-2 and the master base station 100-1 (S32, S33). For example, the CoMP communication control unit 220 of the terminal 200 outputs an instruction to execute the request, and transmits the request signal from the c〇MP communication request signal creation unit 221. The master base station 100-1 determines that CoMP transmission is possible (S31), and when receiving the CoMP execution request from the terminal device 200 (S33), transmits a CoMP execution notification to the slave base station 100-2 and the terminal device 200 (S34, S35). ). For example, the control unit 108 of the primary base station 100-1 transmits a CoMP execution notification to the secondary base station 100-2. Further, for example, the control unit 1 8 outputs a CoMP execution notification to the scheduler 110, and transmits a notification of the execution of the C ο Μ P as a control signal from the scheduler 110 to the terminal 200. 18 201044808 Next, the master base station 100-1 and the slave base station 100-2 perform processing for synchronizing between the base stations (S36). This is because the transmission data is synchronously transmitted to the terminal 200 in the CoMP transmission. For example, the main base station 100-1 and the control unit of the base station 100-2 perform transmission processing by transmitting and receiving signals to each other to synchronize the phases. Then, the master base station 100-1 performs scheduling for performing CoMP transmission (S37). For example, when the scheduler 110 receives the CoMP execution notification from the control unit 1A, the scheduler 110 performs scheduling according to the radio channel quality (S29, S30) or the like. The scheduled information is included in the frequency of use and precoding of the CoMP transmission. Next, the master base station 100-1 transmits the cell information to the slave base station 100-2 (S38). For example, the cell information signal creation unit 1〇6 inputs the cell number and the terminal number from the wireless line control unit 105, and inputs the slot number output from the scheduler 110 to create a cell number, a terminal number, and a slot number. Send after cell information. For example, when the cell number and the terminal number are set to the terminal 200 (S13), the radio channel control unit 1〇5 is created, and the cell information creating unit 106 is controlled by the control unit 丨〇8. The cell number or the like can be read from the wireless line control unit 1〇5 as a result of the execution notification. Regarding the slot number, the scheduler 110 can also schedule (S 3 7) and output the number to the cell information creating unit 106. Further, the terminal unit 2 can directly notify the main base station of the measured quality of the radio channel from the base station 100-2. Next, the primary base station 100-1 transmits the transmission data (for example, the transmission data to the secondary base station 100-2 (S39). For example, the primary base station (7) ~ the scheduler Π 0 is stored in the transmission data buffer. In the transmission data of 113, a portion of 19 201044808 copies (for example, transmission data 2) is read and sent to the slave base station 1〇〇_2. The transmission data buffer 113 from the base station 100-2 is memorized from the primary base station 1 〇〇 _ ^ Sending the transmitted data. Sending the data 发送 and sending the data 2 are different depending on each cell. Then, the main base station 〖 〖 will send the control information to the base station 100-2 (S40 For example, the scheduler n〇 transmits schedule information (S37) including precoding information and the like as transmission control information to the slave base station 1〇〇 2. Next, the master base station 100-1 and the slave base The station 100_2 performs transmission signal processing (S41, S42). For example, the scrambling code creation unit of the primary base station is mutated according to the cell number of the wireless line control unit 105 and the terminal number and the slot number of the scheduler 110. The code modulation unit 114 uses the scrambling code to feed > Then, the data is transmitted, encoded according to the schedule (S37), etc. On the other hand, the scrambling code creation unit 112 of the base station 100-2 uses the cell information transmitted from the primary base station 100-1 (S38), As the scrambling code, the code modulation unit 114 performs a scrambling process on the transmission data 2. The transmission data 2 is encoded in accordance with the transmission control information transmitted from the main base station 100-1, etc. Thus, the main base station 100-1 and the slave base station 1 〇〇_2 creates a scrambling code from the common cell number, terminal number, and slot number, so that the same scrambling code can be created. The human-master base station 100-1 transmits the control signal and the transmission data to the terminal 200 ( S43, S44). The control signal includes the use frequency and precoding information, etc., in addition to the coding rate used for CoMP transmission, and the like, and includes cell information created by the cell information signal generating unit 106. Then, 'from the base station 100- 2, sending the transmission data (for example, the transmission data 2) different from the transmission data sent by the primary base station 1〇〇_1 to the terminal device 20 201044808 200 (S45). For example, the transmission data 1 and the transmission data 2 are based on Coded information, plus Next, the terminal 200 performs reception signal processing on the transmission data transmitted from the primary base station 100-1 and the base station 100-2 (S46). For example, the terminal setting control unit 20 of the terminal 200 The receiving wireless unit 202 and the demodulation decoding unit 203 are controlled to receive data transmitted by each of the primary base station 100-1 and the secondary base station 100-2 based on the schedule information included in the control signal (S43). The scrambling code creation unit 207 of the machine 200 creates a scrambling code based on the cell information (S10 or S43). Since the cell information is the same as that of the primary base station 100-1 and the base station 100-2, the terminal 200 can create the same scrambling code as the base station 100-1, 100-2. The demodulation and decoding unit 203 performs descrambling processing on the transmission data 1 and the transmission data 2 in accordance with the scrambling code. As described above, in the first embodiment, when the CoMP transmission is performed, the master base station 100-1 transmits the cell information to the slave base station 100-2 (S38), so that the information for creating the scrambling code is shared, and the information can be created. Common scrambling code. Therefore, compared with the scrambling code which is different in each base station 100-b 100-2, the wireless communication system can reduce the processing. Further, since the processing can be reduced, the power consumption of the terminal 200 and the base stations 100-1 and 100-2 can be reduced. Moreover, the primary base station 100-1 transmits the precoding information to the base station 100-2 (S40) 'two base stations 100-1, 1〇〇_2 to transmit different data to the terminal 200 according to the precoding information. . Therefore, since different data is transmitted from the two base stations 100-b 100-2 even if the common scrambling code is used, the terminal 200 can perform reception processing according to the pre-encoded information contained in the control signal (S43, S46), 21 201044808 can also prevent interference from 2 different data. <Second Embodiment> Next, an example of the upward direction will be described. The second embodiment is an example in which data is transmitted from the terminal 200 to the uplink direction of the base stations 100-1 and 100-2. Fig. 9 is a view showing a configuration example of the wireless communication system 1 of the second embodiment. The primary base station 100-1 transmits a control signal to the terminal 200. The terminal 200 transmits different transmission data (USCH) to the primary base station 100-1 and the secondary base station 100-2 in accordance with the received control signal. <Configuration Example of Main Base Station> Next, a configuration example of the main base station 100-1 of the second embodiment will be described. Fig. 10 is a view showing an example of the structure of the main base station. The main base station 100-1 has a radio channel quality measurement and calculation unit (hereinafter referred to as a calculation unit) 121. The calculation unit 121 measures the radio channel quality with the terminal device 2 in accordance with the pilot signal or the like transmitted from the terminal device 200, and measures the radio channel quality (for example, CQI). Further, the scheduler 11 of the master base station 100-1 performs the schedule in the uplink direction, and controls the demodulation and decoding unit 103 and the reception radio unit 102 based on the schedule information created. Further, the scrambling code creation unit 112 performs descrambling processing on the transmission data and the like transmitted from the terminal device 200, and outputs the generated scrambling code to the demodulation and decoding unit 103. <Configuration Example of Base Station> Next, a configuration example of the base station 1〇〇_2 of the second embodiment will be described. Fig. 11 is a diagram showing a structural example of the base station 1〇〇_2. 22 201044808 The slave base station 100-2 also has a calculation unit 121. Further, the scheduler 11 of the base station 100-2 is arranged in the uplink direction, and the demodulation and decoding unit 103 and the reception radio unit 102 are controlled based on the schedule information. Further, the scrambling code creation unit 112 performs descrambling processing on the transmission data transmitted from the terminal device 2, and outputs the generated scrambling code to the demodulation decoding unit 103. <Configuration Example of Terminal Machine> Next, a configuration example of the terminal unit 2〇〇 of the second embodiment will be described. Fig. 12 is a view showing a configuration example of the terminal device 200. The terminal unit 2 is also configured in the same manner as the terminal unit 200 (Fig. 5) in the downward direction. The terminal setting unit 209 controls the code modulation unit 213 by performing processing such as encoding on the control signals by transmitting data to the base stations 100_i and i〇〇_2. Further, the terminal setting control unit 2〇9 controls the transmission radio unit 214 based on the precoding information included in the control signal to weight the different transmission data and transmits it to the base station 100-1 '100-2. Further, the scrambling code creation unit 207 outputs a scramble code to the code modulation unit 213 for performing scrambling processing on the transmission data to be transmitted to the base stations 1A, ι, and _2. <Configuration Example of Scrambling Code Composing Unit> The scrambling code creating units 112 and 207 of each of the base stations 100-b 100-2 and the terminal unit 2 are the same as those of the first embodiment. <Operation Example in the Upward Direction> Next, an operation example of the second embodiment will be described. Fig. 13 and Fig. 14 23 201044808 is a flow chart showing the operation example. After the line is set between the main base station 100-1 and the terminal unit 2〇0_ (S10 to S1 3), the terminal unit 2 transmits the pilot signal to the main base station 1〇〇_1 (S5〇). For example, the transmitting wireless unit 214 of the terminal 2 transmits a pilot signal and transmits it. The cell information (sio) transmitted by the primary base station 10〇-i may also contain cellular information made by the cell signal generation unit 106. Next, the master base station 100-1 measures the quality of the radio channel in the uplink direction according to the pilot signal (for example, the measurement unit 121 of the master base station 1〇〇1 performs measurement, etc.) Then, the main base station 100- 1. The scheduling in the uplink direction is performed according to the measured radio channel quality (S16). For example, the scheduler 110 schedules according to the radio channel quality output by the calculation unit 121. Next, the main base station 100-1 transmits the inclusion. The control information of the schedule information in the uplink direction is ss (S18), and the terminal 200 performs transmission signal processing according to the control signal (S52). For example, the control signal generation unit 111 of the main base station 100-1 is configured to include the row. The control signal of the program information is transmitted by the code modulation unit 114, etc. Further, the code modulation unit 213 of the terminal 200 encodes and modulates the transmission data based on the schedule information included in the received control signal. Then, the terminal device 200 transmits the transmission data to the main base station 100_1 (S5 3). Next, the terminal device 200 performs processing such as line setting between the slave base station 100_2 (S21 to S24). Then, at the terminal unit 2 With base station 1〇 The processing for performing CoMP transmission is performed between 〇_1 and 100-2. First, the terminal 200 transmits a CoMP transmission execution request to each of the base stations 2010-1808, 100-1, 100-2 (S32 to S33). The c〇Mp communication control unit 220 of the terminal 200 instructs the CoMP transmission execution request when the received power of each radio channel quality is equal to or greater than the threshold. The c〇Mp communication request signal creation unit 221 creates a c〇MP communication request based on the instruction. The signal is sent to the base stations 100-1, 100-2. Next, the terminal 200 transmits a pilot signal to each base station 1〇〇_ι, 100-2 (S54, S55). Then, each base station 100-1, 1〇〇_2 measure the quality of each radio channel (S56, S57). For example, the radio channel quality is measured by the calculation unit 121 of each base station 1 (M, 1〇〇_2). The base station 100-2 transmits the measured radio channel quality to the main base station 100-1 (S58). For example, the radio channel quality measured from the calculation unit 121 of the base station 1〇〇_2 is transmitted to the main station. Base station iooq. After that, the main base station 100-1 determines the coMP transmission according to the quality of the two radio lines (S3) 1). For example, when the two radio channel qualities are equal to or greater than the threshold, the control unit 1 8 determines that C〇MP transmission is performed. Further, compared with the radio channel quality measured by the main base station 100-1. The threshold value and the threshold value compared with the radio channel quality measured from the base station 100-2 may be the same or different. When the primary base station 100-1 performs CoMP transmission, the CoMP transmission execution notification is transmitted to the slave base station. 100-2 and terminal 2〇〇 (S34 to S35). Then, the master base station 100-1 performs a scheduling process for performing c〇MP transmission with the slave base station 100_2 (S36)' (S37), and notifies the cell information as in the first embodiment. From the base station 00_2 (S38). Cell 25 201044808 Information includes cell number, terminal number and slot number. Thereafter, the main base station 100-1 transmits transmission control information including scheduling information (S37) of the transmission data in the uplink direction to the slave base station 100-2 (S4 〇), and transmits the control signal to the terminal 200. (S43). The control signal may also include cellular information created by the cellular information signal generating unit 106. In addition, the transmission control information and control signals also include the frequency of use and precoding information. Next, the terminal 200 performs transmission signal processing in accordance with the received control signal (S59). For example, the scrambling code creation unit 207 creates a scrambling code based on the cell information extracted by the cell information extracting unit 206 (S10 or S43), and outputs the generated scramble code to the code modulation unit 213. The coding and modulation unit 213 performs the scrambling process using the same (or common) scrambling code, for example, for the transmission data 1 and the transmission data 2 which are different for each cell. Further, the terminal setting control unit 2〇9 of the terminal 200 controls the code modulation unit 213' to perform processing such as encoding in accordance with the received schedule information. Further, the terminal setting control unit 209 controls the transmission radio unit 214 to output the weighted transmission data based on the precoding information included in the control signal. Then, the terminal 200 transmits different transmission data (for example, transmission data i and transmission data 2) to the primary base station 100-1 and the secondary base station 100-2 (S60, S61). For example, the transmitting radio unit 214 rotates the transmitted data weighted according to the precoding information contained in the control signal. Next, the main base station 100-1 performs reception signal processing on the transmission data (S62). For example, the scrambling code creation unit 112 of the main base station lood creates a scrambling code based on the slot number (S37) determined by the scheduler 110 and the cell number and the terminal number of the radio channel control unit 〇5. The generated scrambling code is rounded up to demodulation 26 201044808, and the transmission data 2 is descrambled. Thereafter, the demodulation and decoding unit 103 performs processing such as demodulation and decoding of the transmission data. Further, the transmission data is subjected to reception signal processing from the base station 100-2 (S63). For example, the scrambling code creation unit 112 from the base station 1〇〇_2 follows the cell information transmitted by the main base station 100-1 (S38) to generate a scrambling code. The scrambled code is output to the demodulation decoding unit 103, and the transmission data is descrambled. For example, the base e10 (M, 100_2 uses the same scrambling code as the scrambling code used by the terminal device 2 in the scrambling process, and performs descrambling processing on the transmission data i or the transmission data 2, respectively. Then, 'from the base station 100 -2, the transmission data 1 subjected to demodulation or the like is transferred to the main base station 100-1 (S64). For example, the demodulation and decoding unit 103 of the base station 1〇〇_2 is controlled by the scheduler 11 The transmission data i is transmitted to the main base station 100-1. Thus, in the second embodiment, since the main base station 100J also transmits cell information to the slave base station l〇〇_2 (S38), the base station The station 100-2 can be made the same scrambling code as the main base station 100-1. Further, since the cell information is also transmitted from the main base station 100-1 to the terminal unit 200, the terminal unit 200 can also be made with the base station 100. -1, 100-2 the same scrambling code. Therefore, compared with the case of creating different scrambling codes, the wireless communication system 10 can reduce the processing. Moreover, the terminal 200 on the transmitting side and the base stations 100_ι on the receiving side , ι〇〇_2 can not be made into different scrambling codes, and can be used to reduce power consumption. <Other Embodiments> The other embodiments will be described. The above embodiments are described by the judger who performs CoMP transmission by the primary base station 100-1 (S31 in Fig. 8 and the like). 27 201044808 For example, the terminal 200 can also perform For example, the CoMP communication control unit 220 of the terminal 200 determines whether or not the wireless communication quality is measured based on the measured wireless communication quality (S27 in FIG. 7). Since it is not transmitted to the base station 100-b1, 2, the processing of the primary base station 100-1 can be further reduced. Further, the above embodiments are described by the terminal 200 performing the execution request of the CoMP transmission. In other words, the primary base station 100-1 can also perform the execution request. If the primary base station 100-1 determines to perform c〇Mp transmission in the downlink direction (S31), the CoMP execution request can also be sent to the terminal 200. And the slave base station 100-2. Thereafter, the master base station 〇〇 _ _ can be executed by the notification execution notification (S34, S35). In addition, the 'upstream direction can be sent by c〇Mp (S31)' Send CoMP transmission request to the terminal 2, etc., notify (S34 to 35) The CoMP execution notification is executed. The configuration example of the terminal device 2 at this time is displayed in Fig. 15 (downward direction) and Fig. 16 (upward direction). The terminal device 2 is the same as the above embodiment. Since there is no C〇MP communication control unit 220 and c〇MP communication request signal creation unit 221, it is possible to further reduce the power consumption. The above embodiments are from the main base station 丨 丨 and ^ An example of sending and transmitting data by two base stations of 100-2 is described.

The main communication unit has a master-slave communication unit 150-2 having a slave unit 28, a unit 102 in the 201044808 100-2, and the like. For example, the wireless line quality information is output from the communication unit 15〇_2 to the main communication unit 150-1, and the main communication unit 15〇_1 outputs the cell information or the like to the slave communication unit 150-2. Thereby, the base station 1 can be executed in the same manner as in the first and second embodiments in the downlink direction and the uplink direction.
