C Real Mode 3 Mode for Carrying Out the Invention Hereinafter, the present embodiment will be described in detail with reference to the drawings. [First Embodiment] Fig. 1 is a schematic diagram of a mobile communication system according to a first embodiment. The first implementation 7 201134131 The mobile communication system has a base station device, a wireless relay device 2, and mobile communication devices 3 and 4. The base port device 1 communicates with the mobile communication devices 3, 4 directly or via the wireless relay device 2. The wireless relay device 2 can relay wireless communication between the base station device and the mobile communication device 3, 4. The wireless towel relay device 2 can be a fixed wireless device or a mobile track device. The base station device and the wireless relay device 2 may also have other non-financial devices. Action pass. The fl devices 3, 4 are connected to the base station device or the wireless relay device 2 for wireless communication. Here, it is conceivable that the mobile communication device 3 is connected to the base station device 1, and the mobile communication device 4 is connected to the wireless relay device 2. The base station device 1 has a first generation unit 1a and a second transmission unit 1b. The first part of the department generates a first notification message. The third notification information is information shared by the mobile communication device 3 connected to the base station device 1 and the mobile communication device 4 connected to the wireless relay device 2. The first notification information includes information such as the frequency T width used to display the mobile communication system. The first transmitting unit 1 transmits (broadcasts) the first notification information generated by the first generating unit la. The first notification information is transmitted by, for example, a broadcast channel. The wireless relay device 2 includes a second generating unit 2a and a second transmitting unit 2b. The information of the second generating unit 2a is used by the mobile communication device 4 connected to the wireless relay device 2, but the mobile communication device 3 connected to the base station device 1 is not used. The second notification information includes information about radio resources that can be used by the wireless relay device 2, information on the timing of wireless communication performed by the wireless relay device 2, information indicating the transmission power of the wireless relay device 2, and display. Information on the number of relays for wireless communication. The second transmitting unit 2b transmits (broadcasts) the second notification information generated by the second 201134131 generating unit 2a. The second notification information is transmitted using, for example, a broadcast channel. Here, the wireless relay device 2 can also transfer the first notification information transmitted by the base station device 1. That is to say, the first notification information can also be received by the base station device 1, and the received first notification information can be retransmitted by the broadcast channel of the wireless relay device 2. At this time, the first notification information received by the base station apparatus 1 may be demodulated and decoded, re-encoded, and then modulated, and then transmitted. The first notification information and the second notification information can be sent through the same broadcast channel or through different broadcast channels. The mobile communication device 4 has a receiving unit 4a and a control unit 4b. The receiving unit 4a receives the second notification information by the base station device 1 or the wireless relay device 2, and the second relay information is received by the wireless relay device 2. The i-th notification information and the second notification information can be received at the same timing or at different timings. The control unit uses the reception. Ma receives the first! And the second notification information 'controls the wireless communication that is connected to the wireless relay device 2. It can confirm the connection with the wireless towel relay device 2: refer to the first and second notification information, and can also refer to the first and second notification information after confirming the communication control after the connection. For example, the control °Mb can be based on the relevant information contained in the second notification information.

Quality measurements and cell selection for displaying wireless communication cells can be used. Further, the information on the number of relays is used to control the transmission delay between the base unit 201134131 and the mobile communication device 4. In the mobile communication system according to the first embodiment, the base station device 1 transmits the first notification information for connecting to the mobile communication device 3 connected to the base station device 1 and to the wireless relay. The processing performed by the mobile communication device 4 of the device 2. Further, the wireless relay device 2 transmits the second notification information for processing by the mobile communication device 4. The mobile communication device 4 receives the first and second notification information 'to perform wireless communication with the wireless relay device 2 based on the received notification information. Thus, in the case where wireless communication is performed by connecting to the base station device 1, the mobile communication device 3 should refer to the first notification message generated by the base station device 1. On the other hand, when wireless communication is performed by connecting to the wireless relay device 2, the mobile communication device 4 refers to the first notification information and the second notification information generated by the wireless relay device 2. Thereby, the communication via the wireless relay device 2 can be appropriately controlled. Such a mobile communication system can be realized in an LTE-Advanced (Long Term Evolution-Advanced, hereinafter referred to as LTE-A) system as discussed by the 3GPP (3rd Generation Partnership Project). However, the above wireless communication method can of course be applied to other types of mobile communication systems. [Second Embodiment] Fig. 2 is a schematic diagram of a mobile communication system according to a second embodiment. The mobile communication system according to the second embodiment includes a base station 100, relay stations 200, 200a, and 200b, and mobile stations 300 and 400. The mobile communication system can be implemented as, for example, an LTE-A system. 10 201134131 The base station 100 is a wireless communication device that wirelessly communicates with the mobile stations 300 and 400 directly or via the relay stations 200, 200a, and 200b. The base station 1 is connected to a wired high-level network (not shown) to transmit data between the high-end network and the mobile stations 300, 400. The base station 100 manages at least one cell. As will be described later, the base station 100 uses a plurality of (e.g., five) frequency bands called a carrier component (CC: Component Carrier) for wireless communication. Also, the base station can be called a BS. The relay stations 200, 200a, and 200b are wireless communication devices capable of relaying wireless communication between the base station 1 and the mobile stations 300 and 400. The relay stations 2, 200a, 200b manage cells independent of the cells of the base station 100, respectively. The cells of the base station 1 and the relay stations 200, 200a, and 200b are assigned different cell IDs, respectively. As will be described later, the relay stations 200, 200a, and 200b use a part (e.g., one of five carrier components) for wireless communication. Further, the relay station may be referred to as an RS (Relay Station) or RN (Relay Node), and the mobile station 300 and 400 are wireless terminal devices that are connected to the base station 100 or the relay stations 200, 200a, and 200b to perform wireless communication, such as Mobile phones and mobile terminal devices. The mobile stations 300, 400 receive the data from the base station 1 and transmit the data to the base station 100. Here, it is considered that the mobile station 300 is connected to the base station 100 to perform wireless communication, and the mobile station 400 is connected to one of the relay stations 200, 200a, and 200b (particularly, the relay station 200) to perform wireless communication. Also, the mobile station can be referred to as an MS (Mobile Station). Fig. 3 is a schematic diagram showing an example of setting a carrier component. The base station 100 can use up to five carrier components (CC#1 to CC#5) in communication with the mobile station 300. The relay stations 200, 200a, and 200b can use a part of CC#1 to #5 (for example, cc#3) in communication with the base station 1 and the mobile station 400 11 201134131. The carrier components that can be used by the repeaters 200, 200a, 200b are small because it is assumed that the number of mobile stations that can be received is less than that of the base station 100. When FDD (Frequency Division Duplex) is used for bidirectional communication, the downlink (DL: DownLink) and the uplink (UL: UpLink) can secure the frequency bands of CC #1 to #5, respectively. Hereinafter, when only a carrier component is referred to, it means a combination of a combination of a DL frequency band and a UL frequency band. The frequency bandwidth of each carrier component of the DL and UL may be, for example, 2 〇 MHz, and the frequency bandwidth of the entire mobile communication system may be, for example, 100 MHz. The base station 100 performs radio resource allocation (scheduling) for each of CC#1 to #5. The relay stations 200, 200a, 200b perform allocation of radio resources for communication with the mobile station 400. Furthermore, although the example of Fig. 3 realizes two-way communication by FDD, it is also possible to realize two-way communication by time division duplex (TDD: Time Division Duplex). In this case, five bands are set without distinguishing between DL and UL on the frequency axis. Further, in the above description, although the bandwidth of all carrier components is set to 20 MHz, other bandwidths (e.g., i.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, etc.) may be set. Furthermore, all carrier components may not be set with the same frequency bandwidth. Fig. 4 is a schematic diagram showing a configuration of a radio frame. As shown in Fig. 4, the wireless frames are transmitted in CC# 1 to #5 respectively. Different radio frames are transmitted between the base station 100 and the relay station 200, and between the relay station 200 and the mobile station 400. Here, it is assumed that two-way communication is realized by FDD. The wireless frame of i〇ms contains 10 lms sub-frames (sub-frames #0~#9). 12 201134131 The DL radio frame sets the primary synchronization channel (P-SCH: Primary Synchronization CHannel) and the secondary synchronization channel (S-SCH: Secondary Synchronization CHannel) for transmitting synchronization signals in sub-frames #0 and #5. In sub-box #0, a physical broadcast channel (PBCH: Physical Broadcast CHannel) and an extended physical broadcast CHannel (E-PBCH: Extended Physical Broadcast CHannel) for transmitting notification information are set. The sub-frames #4, #9 set a downlink physical shared channel (PDSCH: Physical Downlink Shared CHannel), and the downlink entity shared channel includes a paging channel (PCH: Paging) for transmitting call information (paging) of the mobile station. CHannel). The radio resources in the radio frame are managed in the frequency direction and time direction. For example, ’FDMA (Orthogonal Frequency Division Multiple Access) can be used for the DL frame, and SC-FDMA (Single-Carrier Frequency Division Multiple Access) and NxSC-FDMA (N Times Single-Carrier Frequency Division Multiple Access) can be used for the UL frame. Radio resources in the frequency x time range are allocated to various channels. The allocation control of wireless resources is performed in sub-frame units. In the time direction, the sub-box contains 2 slots. Each slot contains 6 or 7 symbols. An interval signal called CP (Cyclic Prefix) is inserted between the symbols. There are generally CPs with different lengths of conventional CP and extended CP. In the case of a regular CP, one slot contains seven symbols, and in the case of an extended CP, one slot contains six symbols. In the frequency direction, each sub-frame contains a plurality of sub-carriers. Fig. 5 is a schematic diagram showing an example of allocation of an extended broadcast channel. In Fig. 5, the horizontal direction is the longitudinal direction and the longitudinal direction is the time direction. The example in Fig. 5 shows the case where the conventional Cp is used as the CP, that is, the case where the slot contains 7 symbols 13 201134131. The first symbol of the half slot (slot #〇) of the sub-frame #0 is set to PCFICH (Physical Control Format Indicator CHannel) and PHICH (Physical Hybrid automatic repeat request Indicator CHannel). The PCFICH is a channel for notifying the number of symbols used by the downlink physical control channel (PDCCH: Physical Downlink Control CHannel). PHICH is used to reply to the channel of ACK (ACKnowledgement) response or NACK (Negative ACKnowledgement) response to data reception. The PHICH can also be set to the third symbol. Further, the first symbol of the slot #0 is set with the PDCCH described above. The PDCCH is used to transmit Ll/L2 (Layer1/Layer2) control information. The PDCCH can also be set to the second and third symbols. The number of symbols of the PDCCH can vary from one to three. Further, the sixth symbol of slot #0 is set with S-SCH, and the seventh symbol is set with P-SCH. The P-SCH is used to transmit a channel of any of a predetermined number (e.g., three) of primary synchronization signal sequences. The S-SCH is used to transmit a channel of any of a predetermined number (e. g., 168) of sub-synchronization signal sequences. The combination of the P-SCH sequence and the S-SCH sequence (e.g., three X168 = 504 combinations) corresponds to the cell ID. The first to fourth symbols of the sub-frame correction half-slot (slot #1) are set with PBCH. The 5th to 7th symbols are set with E-PBCH. The PBCH is a broadcast channel defined by LTE (the specification of the previous generation of LTE-A) and LTE-A. E-PBCH is a broadcast channel that is not defined by LTE. In the field of frequency X time, PBCH and E-PBCH are adjacent in the time direction. By adjacency, channel search between the two becomes easy. Set 14 201134131 The frequency of the PBCH and the frequency of the setting Ε-PBCH can be the same or different. The notification information commonly referred to by the mobile station 300 connected to the base station 100 and the mobile station 400 connected to the relay station 200 (or other relay station) is transmitted by the PBCH. The notification information includes, for example, information indicating the frequency bandwidth of the carrier component of the PB CΗ setting. On the other hand, the notification information (relay information) about the relay referred to by the mobile station 400 connected to the relay station 200 (or other relay station) may be transmitted in PBCH or may be in Ε-PBCH as described later. send. Further, in the DL radio frame, a reference k number (RS: Reference Signal) belonging to a known pilot signal can be transmitted using one of radio resources other than the radio resources of the above-mentioned channel. The relay stations 200, 200a, 200b and the traveling stations 300, 400 can measure the received power and the reception quality using the reference signals. In addition, FIG. 5 is only an example of the Ε-PBCH position setting, and may be set to other positions. For example, consider the following position settings: (丄) 4th and 5th symbols of slot #0 (2) slot 4〇, 4th and 5th symbols, and slot #1, 5th to 7th (3) slots The seventh symbol of #1 (4) The fourth symbol of slot #0 (5) The sixth symbol of slot #1. Further, in the field of frequency X time, PBCH and Ε-PBCH may be adjacent in the frequency direction. Figure 6 is a schematic diagram showing a sequence of timings in which a relay station receives and transmits information. The relay station 200 suppresses radio wave interference, and the DL system controls the reception from the base station 1 to be different from the transmission to the mobile station 4〇〇. That is, during the transmission processing of the mobile station 400, the reception processing on the base station 100 side is stopped. This is because if the transmission signal sent to the mobile station 400 is bypassed to the base station 100 side, the reception quality of the circuit may be low. Similarly, for the UL, it is controlled that the reception from the swaying station 400 and the transmission to the base station 100 are not performed at the same time. 15 201134131 The timing at which communication between the relay station 200 and the mobile station 400 is not performed (the timing of communication between the base station 100 and the relay station 200) is determined in advance by the base station 100 or the relay station 200. The timing of the UL and the timing of the DL can be set to be linked or set to be independent of each other. Regarding the DL, the timing at which the relay station 200 does not transmit to the mobile station 400 can be set to, for example, the timing at which the base station 100 performs MBSFN (Multimedia Broadcast and multicast service Single Frequency Network) transmission. The MBSFN transmission is a communication form in which a plurality of base stations transmit data of the same content at the same timing and at the same frequency. The sub-frame for MBSFN transmission (MBSFN sub-frame) uses the extended CP using the regular CP with respect to the regular sub-box. The MBSFN transmission is performed by a sub-frame in which any of the synchronization channels (P-SCH, S-SCH), the broadcast channel (PBCH, E-PBCH), and the paging channel (PCH) are not set. That is, MBSFN transmission is performed through any one or a plurality of sub-frames #1 to #3 and #6 to #8. Here, sub-box #7 is a normal sub-frame, and sub-box #8 is an MBSFN sub-frame. In sub-frame #7, base station 100 can transmit data to subordinate mobile station 300. Further, the relay station 200 can transmit data to the mobile station 400 to be subordinate. However, the relay station 200 does not receive data from the base station. On the other hand, in sub-frame #8, the base station 1 can transmit data to the relay station 2A and the subordinate mobile station 300. However, the relay station 200 does not transmit data to the mobile station 400. Therefore, if the mobile station 400 knows that the sub-frame #8-based relay station 200 does not transmit the sub-frame of the data, it can stop the reception processing in the section where the data of the sub-frame #8 is transmitted. Although Figure 6 shows the timing of the DL, the UL timing can be controlled as well. Further, the relay stations 200a and 200b also perform control similar to the relay station 200. Furthermore, the above-described timing control system assumes a frequency band (or radio resource) used for communication between the base station 100 and the relay station 20, and a frequency band used for communication between the relay station 200 and the mobile station 400 ( Or wireless resources) repeated situations. That is, in order to avoid radio wave interference accompanying the repetition of the frequency band, the transmission h stop interval is set. On the other hand, if the frequency band used between the base station 100 and the relay station 200 and the frequency band used between the relay station 200 and the mobile station 400 are not repeated, the transmission stop section may not be set. Figure 7 is a schematic diagram of a relay path between a base station and a mobile station. The base station 100 and the mobile station can communicate via a plurality of repeaters. As shown in Fig. 7, the relay station 2〇〇a relays the wireless communication between the base station 1 and the relay station 2〇〇b. Further, in the case where the mobile station 4 is connected to the relay station 2A, wireless communication between the base station 100 and the mobile station 400 can be relayed. ^ When the mobile station 400 is connected to the relay station 200b, the relay station 2 can relay the wireless communication between the relay station 200a and the mobile station 400. In Fig. 7, although two relay stations are connected in series, three or more relay stations may be connected in series. Here, the number of hops between the base station 100 and the mobile station 400 is defined. The number of hops can be defined as, for example, the number of repeaters passed. Thus, if action eight 400 is connected to relay station 200a, the number of hops is one. If it is connected to the relay I 200b, since the relay stations 200a and 200b pass through, the number of hops is two. Extension Yes, the number of hops can also be defined as the number of wireless links that pass through. At this time, if the mobile station 400 is connected to the relay station 200a, the number of hops is two. If the relay station 200b is connected, the number of hops is three. In addition to defining the number of individual hops 17 201134131 for the mobile station 400, the number of all hops connecting a plurality of repeaters in series can be defined. . The total number of hops is the number of hops in the case where the mobile station 400 is connected to the relay station farthest from the base station 100 (e.g., the relay station 200b). For example, the number of relay stations is counted from the base station 1 to the relay station at the end, and the number of all the hops determined by the end relay station to the base station 100 is transmitted, whereby each relay station can know The total number of hops. Figure 8 is a diagram showing an example of relay information for relay station notification. The relay station 200 can notify the relay information as shown in Fig. 8 so that the mobile station 4 can appropriately control the communication via the relay station 200. The relay information includes information on whether to use rS, RS timing, RS transmit power, and number of hops. However, the relay station 2 can also notify only some of the four types of information. The relay stations 200a and 200b also notify the relay information as well. The presence or absence of information on the RS indicates that the carrier component of the relay information is the information (such as a flag) of the carrier component used by the relay station 200. The mobile station 4 可 can recognize that the communication target is the relay station and the carrier component is the relay station user by referring to whether or not the information of the RS is used. The information of the RS timing is information about the communication timing between the relay station 2 and the subordinate mobile station. The mobile station 400 can intermittently stop the wireless signal processing (e.g., the reception processing of the wireless signal from the relay station 200) by referring to the RS timing information. Information on RS timing can also include information on UL timing and DL timing. The information of the RS timing may be information for displaying the communication timing between the base station 100 and the relay station 200, or may be information for displaying the communication timing between the relay station 200 and the mobile station 400. In addition, the timing of communication can be displayed for display. 201134131: The information on the timing of communication can also be displayed. Regardless of the form of presentation, the mobile station 400 can determine the timing at which the wireless signal processing can be stopped. The sequence 3b is expressed by any method, for example, the number of the sub-frame that does not perform (or perform) data transmission, the set of sub-frame numbers, the number of sub-frames connected to the front terminal (four) serial number, and the like. The information of the RS transmission power is information indicating the transmission power of the reference signal (the pilot tiger transmitted by the relay station 2 (10)). The mobile station 4 calculates the propagation loss from the transmission power by referring to the information of the transmission rate. Further, cell selection and transmission power control can be appropriately performed using the calculated propagation loss. That is, the mobile station 400 measures the transmission power of the reference signal, and calculates the propagation loss from the transmission power of the reference signal transmission source and the transmission power of the secret measurement. If the transmission power is constant regardless of the transmission source and the transmission power is known, the mobile station 400 can easily calculate the propagation loss. However, it can be assumed that the cell radius of the base station 100 and the relay station 200 is different, and the transmission power rate of the reference signal is also different. Therefore, the relay station 2 notifies the information of the transmission power. The mobile station 400 can easily calculate the propagation loss by receiving the information of the transmission power. Further, the mobile station 400 measures the reception power of the reference signal of the peripheral cells, and selects the cell to be accessed in accordance with the received power level. However, it can be assumed that the transmission power of the relay station 200 is smaller than the transmission power of the base station 1〇〇. Therefore, by simply comparing the received power levels, even if the mobile station 4 is located near the relay station 2p, the cells of the base station 1〇〇 may be selected. Therefore, the mobile station can correct (improve) the receiving power of the relay station 2 according to the calculated propagation loss when comparing the received power levels. Thereby, the relay station 200 can be effectively utilized to increase the throughput. Further, the mobile station 400 can control the transmission power from the mobile station 400 to the relay station 200 using the calculated propagation loss. In addition, the mobile station 400 can notify the relay station 2 of the calculated propagation loss. The relay station 200 can control the transmission power from the relay station 200 to the mobile station 400. The mobile station 400 can also transmit the transmission loss control (TPC: Transmission Power Control) command instead of notifying the propagation loss. The number of hops information is the information showing the number of relays of the communication path via the relay station 200. The number of hops includes information indicating the number of hops for the mobile station 4, and the number of sfls showing the number of hops of the longest communication path via the relay station 2. The mobile station 400 can appropriately perform transmission delay control with the base station 100 by referring to the number of hops. That is, the mobile communication system usually sets the maximum transmission delay time corresponding to the required quality of service (q〇s: Quality of Service). For example, for instant messaging such as voice calls, a short maximum transmission delay time is set. However, if the number of hops between the base station 100 and the mobile station 4 is increased, the transmission delay between the two is also increased. In particular, if the relay is transmitted by re-decoding by decoding using the relay method, the transmission delay is greatly increased. Therefore, the swaying station 400 performs transmission delay control in accordance with the number of hops. For example, set the maximum transmission delay time corresponding to the number of hops. That is, the more the number of relays is considered, the more the requirements of the maximum transmission delay time are alleviated. Furthermore, regarding instant messaging, it is conceivable to limit the number of hops, that is, to make cell selections that reduce the number of hops. In addition, it is also possible to calculate the actual maximum transmission delay time from the transmission delay time of the number of segments according to the QoS maximum transmission delay, and to perform the transmission delay control from the actual maximum material delay time. The following is a case in which the base station 1GG communicates via the Towel Station 2_Mobile Station. Figure 9 is a block diagram showing the base station.

Fig. 17 is a flow chart showing a third modification of the communication via the relay station. The flow private example of Fig. 17 replaces the step of Fig. 13; § 15, the step § 1 is implemented. (Step S15a) The base station 10a transmits the notification information in the PBCH. The notification resource sfl includes information indicating the frequency bandwidth of the carrier component. Further, the base station 100a transmits the extension notification information in the E-PBCH. The extended notification information includes information for generating relay information notified by the relay station 200c (e.g., information of the RS timing). The relay station 200c receives the notification information and the extended notification information from the base station 100a. Fig. 18 is a block diagram showing a base station of a second modification. The base station l〇〇b of the second modification transmits information for generating relay information instead of the PBCH but with the R_pDCCH. The base station 10b has a notification information generating unit 117b that replaces the base station 1's notification information generating unit 117. Further, the relay control information generating unit 124 is provided. The notification information generating unit 117b generates notification information transmitted in the PBCH. The notification information includes information on the common reference of the mobile station 300, 400 and the relay station 2 〇〇d described below for communication control. However, it does not include information for generating relay information (such as information showing the timing of the 2011 13131 timing between the base station 1 and the relay station). The relay control information generating unit 124 generates control information transmitted to the relay station 200d by the R-PDCCH. This control information contains information used to generate relay information. The relay station 200d can be realized by the same block configuration as the relay station 200 shown in Figs. In this case, the control information extracting unit 214 extracts the information for generating the relay information transmitted from the base station 100b to the relay station 200d by the R-PDCCH. Fig. 19 is a flow chart showing a second modification of communication through the relay station. The flow example of Fig. 19 replaces step S15 of Fig. 13 and executes step S15b. Further, step S16a is executed between step S16 and step S17. (Step S15b) The base station 100b transmits the notification information on the PBCH. The notification information includes information showing the frequency bandwidth of the carrier component. However, it does not include information used to generate relay information (such as information on RS timing). The relay station 200d receives the notification information from the base station 100b. (Step S16a) The base station 100b transmits control information for relay control on the R-PDCCH after the procedure of the line connection. This control information contains information used to generate relay information. The relay station 200d receives the control information from the base station 100b. Furthermore, as previously mentioned, it is possible for the base station 10b to update information (e.g., RS timing information) for generating relay information. The base station l〇〇b may send control information to the relay station 200d every time the R-PDCCH is updated, or may be periodically transmitted. The relay station 200d generates relay information based on the latest control information received from the base station 100b. Fig. 20 is a block diagram showing a mobile station of a third modification. The mobile station 400&amp; of the three modifications of the 36th 201134131 receives the relay information from the relay station 200e' of the third modification described below with the PBCH. The mobile station 400a has a notification information extraction unit 415a that replaces the notification information extraction unit 415 of the mobile station 400. On the other hand, the mobile station 4A may not have the extended notification information extracting unit 416. The notification information extracting unit 415a extracts the notification information transmitted from the relay station 2〇〇ewpBCH. The notification information includes information showing the frequency bandwidth of the carrier component that sent the notification information. Further, the notification information includes relay information indicating whether or not the RS, the RS sequence, the RS transmission power, and the number of hops are used. The notification information extracting unit 415a notifies the delay control unit 417, the terminal control unit 418, the synchronization control unit 42, the quality determining unit 422, and the quality information generating unit 423 of the content of the extracted notification information in accordance with the type of the information. Further, the relay station 2GGe can be realized by the same block configuration as the relay station shown in the first and fifth figures. In this case, the notification information generation unit generates the notification resource including the relay information based on the instruction from the relay control unit 218. The 21st diagram shows the flow of the third modification of the communication via the relay station. The flow example in Fig. 21 replaces the 13th step S2la. The summer subscription step t (step S2la) relay station period e is transmitted in the PBCH using the notification =' generated at step si5 to generate its notification information. The notification information includes information on the frequency bandwidth of the carrier component. In addition, it includes relay information such as whether or not to use, batch timing, RS transmission power, and number of hops. Also, the relay station 2〇〇e transmits the relay information and other notification information to the € 37 201134131 PBCH. The mobile station 400a receives the notification information from the relay station 200e. Further, in the above description of the second embodiment, the base station 1 determines the timing of the RS and notifies the relay station 200. However, the relay station 2 may determine the base station 100. In this case, a method in which the relay station 2 transmits the RS timing information to the base station 100 by using the UL control channel set between the base station 100 and the relay station 200 can be considered. Further, in the description of the second embodiment described above, the cells of the relay station 2 are given one cell different from the cells of the base station, and the cells of the relay station 4 are connected to the base station 100. The cells are distinguished. However, the above notification method of relay information is also applicable to a system in which the cell line of the relay station 2 is recognized as a part of the cells of the base station 1 for the mobile station 400. According to the mobile communication system according to the second embodiment as described above, the mobile station can appropriately control the wireless communication via the relay station 2 (or the relay stations 2A, 2B). That is, the mobile station 4 receives the relay information of the notification, and knows that the cell to be accessed is the cell of the relay station and the carrier component used by the relay station. Further, the transmission timing of the relay station to be connected can be known, and the wireless signal processing can be intermittently stopped. Thereby, power consumption can be suppressed. For example, wireless communication between the base station 100 and the relay station 2 is performed in four sub-frames of 10 sub-frames included in the radio frame. If the mobile station 4 does not know the communication timing, it is necessary to receive the wireless signal from the relay Δ 200 in the entire interval (10 sub-frames) to determine whether or not there is any data addressed thereto. On the other hand, if the communication timing is known, the mobile station 4 can determine in advance whether or not the wireless signal from the relay station 200 can be received in the four sub-frames. Therefore, in this case, the load of the reception processing is reduced to 6/10, and the power consumption of the mobile station 4〇〇 can be suppressed. 38 201134131 Further, the mobile station 400 can know the transmission power of the relay stations 200, 2A, and 2B, and can calculate the propagation loss from the transmission power and the reception power. Thereby, even when the transmission powers of the relay stations 200, 200a, and 200b are different from those of the base station, cell selection and transmission power control can be appropriately performed. Further, the number of hops between the base station 100 and the mobile station 400 can be known, and the transmission delay control corresponding to the number of hops can be performed. The foregoing is merely illustrative of the principles of the invention. The present invention is not limited to the correct configuration and application examples as described above, and the corresponding modifications and equivalents can be regarded as the scope of application of the appendix and its equivalents. The scope of the invention is constituted. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic diagram of a mobile communication system according to a first embodiment.
