The 13th mutually exclusive logical sum circuit 112-18 is a mutually exclusive logical sum of the outputs of the 12th and 14th mutually exclusive logical AND circuits 112-17, 112-19, and the output is relative to the 3rd mutual The output of the repulsion logic and circuit 112-5 has an agitator of arbitrary phase difference. In this way, the agitation code generating sections 112 and 207 combine the appropriate components by the segments of the two linear shift registers 112-1 and 112-3 by the mutual exclusion logic sum, and can output the phase difference. Stirring code (or most stirring code). For example, the initial value setting unit 112-14 controls the first and second switch groups 112-15 and 112-16 based on the cell information of the master base station 100-1, and the third mutually exclusive ® logic and circuit 112-5 are The stirring code (first stirring code) generated by the main base station 100-1 is output. Further, the initial value setting unit 112-14 controls the first and second switch groups 112-15 and 112-16 based on the cell information and the phase difference information of the slave base station 100-2. At this time, the 13th mutually exclusive logical sum circuit 112-18 outputs the stirring code (e.g., the second stirring code) generated by the slave base station 100-2. <Example of Operation in the Downlink Direction> Next, an operation example of the first embodiment will be described. Figures 10 and 11 ' show the flow of the action example. Further, the terminal device 200 is located in an area where the main base station 19 1376974 100-1 and the slave base station 100-2 can communicate with each other. First, the master base station 100-1 notifies the terminal device 200 of cellular information or the like ( S10). For example, the cell information signal creation unit 106 creates cell information. Next, the primary base station 100-1 transmits a pilot signal (S11). Then, the terminal device 200 selects the cell (S12)' to be the communication target to set a green path between the selected cells based on the received pilot signal or the like (S13). For example, the reception 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 selection cell of the line (e.g., the primary base station 1 〇〇 1). Next, the terminal 200 measures the quality (e.g., C QI) of the wireless line between the main base station and the main base station (S14), and transmits the radio channel quality information to the base station 100-1 (S15). For example, the calculation unit 2〇4 of the terminal unit 2 measures the quality of the radio line based on the pilot signal. Next, the main base station 100-1 performs scheduling based on the radio channel quality information (S16). For example, the main base station ioo-丨's scheduler ι1〇 is scheduled based on the wireless line quality information extracted from the wireless line quality tribute capture unit 1 〇 9. Next, the main base station 100-丨 performs transmission signal processing (S17). For example, the code modulation unit 114 reads the transmission data stored in the transmission data buffer 113, and performs processing such as encoding based on the schedule information. Next, the master base station 100-i transmits the control signal and the transmission data to the terminal device 200 (S18, S19). The terminal 200 receives the control signal and transmits the data, that is, performs the reception signal processing (S20). For example, the terminal setting control unit 2〇9 controls the receiving radio unit 2〇2 and the demodulation and decoding unit 203 to perform demodulation, decoding, and the like in accordance with the schedule information included in the control signal received by the receiver 20 1376974. Next, the terminal 200 receives the cell information and the like and the pilot signal notified by the slave base station 2 (S21, S22). Further, the terminal device 2 selects the slave base station 100-2 as a connection base station (S23), and sets a line between the slave base station 100-2 (S24). Next, the process for CoMP transmission is performed between the terminal 200 and the base stations ι〇〇·ι, i〇〇_2. First, the terminal unit 2 receives the pilot signals (S25, S26) from the master base station and the slave base station 100-2, and measures the line quality of each wireless line (S27). Further, at this time, in order to easily recognize the pilot signals from the master base station 100·1 and the slave base station 100·2, it may be used as the cell number based on the master base station 100-1 and the slave base station 1〇〇2. The original cell number is made into a different indication signal. Next, the terminal 200 transmits the measured radio channel qualities to the slave base station 100-2 and the master base station 100-1 (S28, S30). The slave base station 100-2 transmits the wireless channel quality information transmitted by the terminal set 200 to the master base station l〇〇-1 (S29). For example, the wireless channel quality information capturing unit 1 〇 9 of the slave base station 〇〇 〇〇 2 transmits the wireless channel quality transmitted between the terminal and the terminal 2 to the primary base station 100-1. Furthermore, the master base station 100-1 determines whether or not the CoMP transmission can be performed (S3U. For example, the control unit 108 of the master base station 100-1 is connected to the radio channel quality and the CoMP communication request signal from the slave base station 100-2. When the quality of the wireless line extracted by the capturing unit 107 is above the limit value, it is determined that CoMP communication can be performed. The 21 1376974 limit value compared with the quality of the wireless line from the main base station ιοο-丨 and the slave base station 100- The limit value of the wireless channel quality comparison of 2 may be the same or different, and when the control unit 108 determines that CoMP transmission is not possible, the series of processing ends. Next, the terminal 200 transmits a CoMP transmission implementation 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 unit 2 outputs an instruction to execute the request, and the CoMP communication request signal creation unit 221 transmits the request signal.

The primary base station 100-1 determines that CoMP transmission is possible (S31), and when the terminal 200 receives the CoMP implementation request (S33) 'Sends the CoMP implementation notification to the secondary base station 100-2 and the terminal 200 (S34, S35) . For example, the control unit 108 of the primary base station 100-1 transmits a CoMP enforcement notification to the secondary base station 100-2. Further, for example, the control unit 108 outputs a CoMP implementation notification to the scheduler 110, and the scheduler 110 transmits a CoMP implementation notification to the terminal 200 as a control signal.

Next, the master base station 100-1 and the slave base station 100-2 perform processing for synchronizing between the base stations (S36). For example, the master base station 1 〇〇-1 and the control unit 108 of the slave base station 100-2 perform signal transmission and reception with each other to perform phase synchronization for synchronization processing. Next, the master base station 100-1 performs scheduling for CoMP transmission (S37). For example, the scheduler 110 receives the CoMP implementation notification from the control unit 108, and schedules it based on the radio channel quality (S29, S30) or the like. The schedule information generated includes the frequency of use and pre-coded information used in CoMP transmission. Next, the primary base station 100-1 transmits the cell information and phase difference information 22 1376974 to the slave base station l〇〇-2 (S38). For example, the cell information generating unit 106 of the main base station 100-1 transmits the phase difference information of the cell information transmitted from the station and the pre-holding. The phase difference information can also be held by the wireless line control unit 105. Next, the master base station 100-1 transmits the phase difference information to the terminal device 200 (S39). For example, the cell information signal creation unit 106 of the main base station 100-1 transmits the created phase difference information by using the code modulation unit 114 or the like as an intermediary. Next, the master base station 100-1 transfers the transmission data (for example, the transmission material 2) to the slave base station 100-2 (S40). For example, the scheduler 110 of the master base station 100-1 reads out a portion of the data (e.g., the transmission material 2) of the transmission data stored in the transmission data buffer 113, and transmits it to the slave base station 100-2. The transmission data buffer 113 of the slave base station 100-2 memorizes the transmission data transmitted by the master base station 100-1. Send data 1 and send data 2, such as sending data for each cell. Next, the master base station 100-1 notifies the slave base station 100-2 of the transmission control information (S41). For example, the scheduler 11 transmits the schedule information (S37) containing the preamble data or the like as the transmission control information to the slave base station 100_2. Next, the main base station 1〇〇_1 and the slave base station 100-2 perform transmission signal processing (S41, S42). For example, the agitation code creation unit 112 of the main base station 100-1 creates a stirring code (for example, a first agitation code) based on the cell information of the self-stage. The code modulation unit 114 of the main base station 100-1 uses the agitation code to perform agitation processing on the transmission data (e.g., transmission data). Further, the stirring/mixing unit 112 of the slave base station 100·2 creates a stirring code (for example, a second stirring code) based on the cell information and the phase difference information transmitted from the main base station 100-1. The code modulation unit 114 of the slave base station 100-2 performs the stirring process on the transmission data 2 by using the created search code. Next, the main base station 100-1 transmits a control signal and transmission data (e.g., transmission material 1) to the terminal 200 (S44, S45). The control signal, in addition to the coding rate used for c〇MP transmission, also includes the frequency of use and pre-encoded data, and may also contain cellular information generated by the cell information signal generation unit 106. Second, the slave base station 100-2 The transmission data (for example, the transmission material 2) different from the transmission data transmitted by the primary base station (9)-丨 is transmitted to the terminal 200 (S46). For example, the transmitted material 1 and the transmitted data 2 are weighted and transmitted according to the pre-encoded information. Next, the terminal device 200 performs reception signal processing on the transmission data transmitted from the main base station wo" and the slave base station 100-2 (S47). For example, the terminal setting control unit 209 of the terminal 200 controls the receiving wireless unit 2〇2 and the demodulation decoding unit 2〇3 in accordance with the scheduling information included in the control signal (S43). At this time, the terminal 200 is agitated. The code creation unit 2〇7 generates a stirring code (for example, a second stirring code) based on the cell information (s!〇 or S43), and outputs it to the demodulation decoding unit 203. Further, the agitation code creation unit 2〇7 creates a stirring code (e.g., a second mixing code) based on the cell information and the phase difference information (S39), and outputs it to the demodulation decoding unit 203. The demodulation and decoding unit 2〇3, for example, performs a descrambling process on the transmission data (e.g., transmission data 发送) transmitted from the main base station 100-1 using the third mash code. Further, the demodulation decoding unit 203 performs the deserial processing of the transmission data (e.g., the transmission material 2) transmitted from the slave base station 1 〇〇 2, for example, using the second search code. As described above, in the first embodiment, when the c〇Mp transmission is performed, the main base station 100-1 mainly generates the agitation code based on the cell information of the main base station iOO-丨, and the slave base station 100-2 is based on The age code of the cell information received by the main base station iooj is taken as the standard, and the stirring code for shifting the pulse difference information is created. The terminal device 200 also notifies the cell information and the phase difference information of the main base station 1〇〇1, and creates the first stirring code generated mainly by the cell information, and the phase difference information shift has been performed. The two stirring codes are used for the demixing treatment. Thereby, in the terminal device 2, the cell information of the base station 1〇〇1 and the cell information of the base station 100-2 are used as the main body, and the two-system stirring code is independently created to perform the demixing process. Compared with the terminal 2, the processing can be reduced. Furthermore, the power consumption of the terminal 200 can also be reduced. Moreover, the master base station 100-1 transmits the preamble information to the slave base station 100-2 (S44), and the two base stations 1〇〇_1 and 1〇〇_2 are based on the pre-coded equipment. Different data is sent to the terminal 2〇〇. Therefore, even if different data is transmitted by the two base stations 100-1, 100-2, the terminal unit 2 can also receive processing according to the pre-coded information contained in the control signal (§ 47), so it can also be prevented. Confusion of two different materials. &lt;Second embodiment&gt; Next, the second embodiment will be described. The second embodiment is another example of the downward chain direction. Fig. 12 is a view showing a configuration example of the wireless communication system 1 of the second embodiment. The slave base station 100-2 transmits cell information to the primary base station 100-1. The main base station 100-1 calculates the phase difference of 25 1376974 of the stirring code used by each base station 100-b 100-2 from the cell information of the slave base station 100-2 and the cell information of the slave base station 100-2. - &lt;Configuration Example of Main Base Station&gt; - Fig. 13 shows an example of the configuration of the primary base station 100-1 of the second embodiment. The cell information signal creation unit 1 〇 6 receives the cell information from the C ο MP implementation base station (for example, the slave base station 100-2). Further, the cell information signal creation unit 106 is a cell number and a terminal number output by the radio channel control unit 105 and a slot number output by the scheduler 110, and the cell information of the self-stage is created. Further, the cell information signal creating unit 106 calculates the phase difference of the agitation code created by each of the base stations 100_1 and 1〇〇_2 based on the two cell information of the master base station 100-1 and the slave base station 100·2. The operation system is detailed later. The cell information signal creation unit 106 outputs the phase difference information to the code modulation unit 114 together with the cell information of the self-stage. The agitation code creation unit 112 creates a stirring code (e.g., a first agitation code) based on the cell information of the self-stage. &lt;Configuration Example of Subordinate Base Station&gt; Fig. 14 shows a configuration example of the subordinate base station game 2 of the second embodiment

The wireless line control unit 105' inputs the coMP implementation 'wireless line control unit' from the control unit 108, for example, so that the cell number, the terminal number, and the slot number held in advance are transmitted to the main base station mu. In addition, the 105 series outputs the cell information to the _Ma making part (1). (4) The code making part (1) is based on the blister information, the _ code of the platform 1〇〇.2, and it is taken out to the code modulation part = in addition to the 'terminal machine 跋 constituting the system and (4) the example (figure 5) same. 26 1376974 &lt;Calculation of phase difference information&gt; Next, the calculation of the phase difference information will be described. For example, the cell information signal creation unit 106 of the master base station 100-1 operates. The operation is performed as follows. In other words, the main base station 100-1 obtains the initial value of the agitation code generated from the cell information of the self-stage, and serves as a column vector of n rows and columns (force (9) xJO) · · · '(9)). The main base station 100-1 obtains a stirring code that has been shifted by one bit from the initial value, and is a column vector U(1) seven (1) · · · χ „(1)), and is obtained from the beginning

The starting value is a 2-bit shifting stirring code as a column vector (χ, (2) χ 2 (2) · · · χ „ (2)). Further, the main base station 100-1 is found to have been performed. The mixing code when the η bit shifts is used as the column vector (々(8) χ2{ή) · · · χ„(«)). The main base station 100-1 obtains the n-column column vector as the row X of the n-row n-column. The rank X is: [number 20] 'X丨(9)X丨(1)...X丨(8), especially 2(9) especially 2(1)...heart (8), 〇)~(1)...\(吟

Similarly, the primary base station 100-1 determines the initial value of the agitation code generated by the cell information of the slave base station 100-2 as a column vector (%(9):^(9)· · · (9)), The row and column Y of the nRn column formed by the n sets of column vectors. The rank Y is: [number 21], (9) less 丨 (1)... less 丨 ("), :^(9) 义(1)...h(8), brother, (〇)凡(1)...·y», here, order rank Y A stirring code for moving the rank X forward by a certain amount of phase. The main base 27 ground stage 1〇〇-1 determines the phase relationship A to determine the phase relationship, and performs the following operations. [Number 22] κ = Α = Α·Χ·^' =Υ·Χ'' The row and column system determines the phase difference between the two stirring codes, and the main base 10〇-1 performs the operation of the number 22 to calculate the phase. difference. The cell information processing unit 106, for example, combines all of the agitation codes, and then holds (or memorizes) the calculation results and the like as a form in advance. Then, the cell information signal as the crotch portion 106' may be configured to take out the tap coefficient (phase difference information) for the phase difference of the arbitrary cell information to the two Dynamics code from the form and output it. The cell information signal creation unit 100 holds, for example, the form. <Example of Operation in the Downlink Direction> Next, an operation example of the second embodiment will be described. The first and fifth diagrams show the flow of the operation example. S10 to S37 are the same as in the first embodiment. Next, the slave base station 100-2 notifies the main unit of the cell information of the station. S50 of Fig. 15). For example, the wireless line control unit 105 of the slave base station 〇〇 〇〇 2 notifies. /, person, main base station 100-1 calculates phase difference information (S51). For example, the main base station 100-丨 cell information signal creation unit 1〇6 is calculated using a form or the like.

The code modulation unit 114 or the like intervenes to calculate the phase difference, and the terminal 200 (852). For example, the unit 106 notifies the terminal device 200 by the code modulation. 1376974. Next, the main base station 1〇〇·1 will send data (such as sending information 2) and send control information to the slave base station l〇〇-2 (S4〇, S41), each base station 100·1 100-2 performs transmission signal processing (S42, S43). For example, each base station 100-1 '100-2 generates a stirring code based on the cell information of the self-stage, and performs a stirring process. Next, the main base station 100-1 transmits a control signal and transmission data (e.g., transmission material 1) to the terminal device 200 (S44, S45). Next, the slave base station 100-2 transmits the transmission data (e.g., transmission material 2) to the terminal device 2GG (S46). Next, the terminal device 200 receives the borrowing from each of the base stations 100-1 and 100-2, and the CoMP transmits the different transmitted data transmitted by the CoMP, and performs reception signal processing (S47). For example, the phase difference information capturing unit 206 of the terminal 200 captures the phase difference information and outputs the result to the stirring code creating unit 207. The agitation code creation unit 207 creates a stirring code (for example, the first transmission code) from the cell information (sl〇, etc.) of the main base station, and outputs the result to the demodulation decoding unit 203. The code creation unit 207 generates a stirring code (for example, a second stirring code) based on the cell information (S10 or the like) and the phase difference data (S52) of the main base station 100-1, and outputs the result to the demodulation decoding unit 2〇3. The demodulation and decoding unit 203 unmixes the transmission data (for example, the transmission material 1) transmitted by the main σ 1 〇〇-1 by using the first agitation code. Further, the demodulation decoding unit 203 uses the second agitation code. In the second embodiment, at the time of CoMP transmission, the primary base station 100-1 calculates the slave base station 100 at the time of the CoMP transmission. -2 is made into the phase of the stirring code and sent to the terminal 200. Therefore, the terminal 200 can be made into a stirring code having a phase difference in advance by 29 1376974. Thereby, the wireless communication system 10 is connected to the terminal 200. Based on the cell information of base station 100-1 and the cell information of base station 100-2, It is possible to reduce the power consumption of the terminal 200 by reducing the power consumption of the terminal system 200 by performing the unmixing process of the two systems which are independent and independent of each other. [Third embodiment] Next, the third embodiment is implemented.

The stirring code creating unit 2〇7 outputs the prepared stirring code (for example, the third stirring code) to the code modulation unit 213. The terminal setting control unit 209 controls the code modulation unit 213 to perform processing such as encoding and transmitting data to the base station in accordance with the control signal. Further, the terminal setting control unit 2〇9, for example, controls the transmission radio unit 214 based on the preamble information included in the control signal of the control unit 31 1376974, and weights the different transmission data to be transmitted to the base stations 100-1 and 100-2. &lt;Configuration Example of Stirring Code Creation Unit&gt; The agitation code creation units 112 and 2〇 of each of the base stations 100-1 and 100-2 and the terminal unit 200 are the same as those of the first embodiment (for example, Fig. 9). &lt;Example of operation in the winding direction&gt; Next, the operation example of the third embodiment will be described. Figures 20 and 21 show the flow of the action example. After the line is set between the primary base station 100-1 and the terminal 200 (S10 to S13), the terminal 200 transmits the pilot signal to the primary base station 10_1 (S6〇). For example, the transmitting radio unit 214 of the terminal 200 generates a pilot signal and transmits the transmitter. The cell information (S10) transmitted from the main base station 100-1 may also contain cellular information created by the cell information signal generating unit 106. Next, the master base station 100-1 measures the radio channel quality (e.g., CQI) in the uplink direction based on the pilot signal (S61). For example, the calculation unit 121 of the main base station 1 〇〇 _ i performs measurement or the like. Next, the main base station 100-1 performs scheduling in the winding direction based on the measured radio line quality (S16). For example, the scheduler is scheduled based on the quality of the wireless line output by the calculation unit 121. Next, the main base station 100-1 transmits a control signal including schedule information in the uplink direction (S18), and the terminal 200 performs transmission signal processing based on the control signal (S62). For example, the control signal creation unit n1 of the main base station 1 作 作 作 作 作 作 作 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有 含有Moreover, the code modulation unit 213 of the terminal 200 encodes and modulates the transmitted data in accordance with the schedule information contained in the received control signal 32 1376974. Next, the terminal device 200 transmits the transmission data to the main base station 100-1 (S63). Next, the terminal device 200 performs processing such as line setting with the slave base station 100-2 (S21 to S24). Further, c终端MP transmission processing is performed between the terminal unit 2A and the base stations 100-1 and 100-2. First, the terminal device 200 transmits a CoMP transmission execution request to each of the base stations 100-1 and 100-2 (S32 to S33). Next, the terminal 200 transmits a pilot signal to each of the base stations 100-1 and 100-2 (S64, S65). Then, each of the base stations 100-1 and 100-2 measures the radio channel quality (S66, S67). For example, the calculation unit 121 of each of the base stations 100-1 and 1〇〇_2 measures the radio channel quality. Next, the slave base station 100-2 transmits the measured radio channel quality to the master base station 100-1 (S68). For example, the calculation unit 121 of the slave base station 100-2 transmits the measured radio channel quality to the master base station 10 (M.
