Description

201129035 VI. Description of the invention: c invention belongs to the technical field 3 FIELD OF THE INVENTION The present invention relates to a mobile communication system, a wireless communication device, a mobile communication device, and a wireless communication method. BACKGROUND OF THE INVENTION Nowadays, mobile communication systems such as mobile phone systems or wireless metropolitan area networks (MANs) are mostly utilized. In addition, in order to pursue higher speed and large capacity of wireless communication, active discussions on the next generation of mobile communication technologies continue. For example, in the 3rd Generation Partnership Project (3GPP), one of the standardization bodies, the proposal to have the largest communication to the 20MHz band is called LTE (Long Term Evolution). Communication specifications of the technology (for example, refer to Non-Patent Document 1). Furthermore, as a communication standard for the next generation of LTE, there is proposed a communication specification called LTE-A (LTE-Advanced) that can be used up to five 20 MHz bands (ie, a band of 100 MHz) (for example, Refer to Non-Patent Document 2). Such a next-generation mobile communication system, sometimes not defined as a system different from the previous generation of mobile communication systems, is defined as an extension of the previous generation of mobile communication systems. In this case, the base station or the relay station corresponding to the communication specifications of the next generation may also be required to have the rear interchangeability of the mobile station that can accommodate the communication specifications corresponding to the previous generation. For example, the above-mentioned 201129035 LTE-A is proposed as a communication standard for expanding LTE. Therefore, the base station or the relay station corresponding to LTE-A is required to accommodate both the mobile station corresponding to LTE and the mobile station corresponding to LTE-A. In addition, in the case where the base station transmits individual control signals to its own terminal, a communication system is proposed which can use the extended radio resource area as an individual control channel to transmit individual control signals (for example, refer to Patent Document 1). Moreover, in the LTE system, it is proposed to prohibit the base station from all the mobile stations by using the Access Barring Information which informs the channel of the System Information Block (SIB). The accessor (for example, refer to Section 6.3.1 of Non-Patent Document 1).

C. In the case of the invention, the problem to be solved by the invention is that the wireless communication device such as the base station or the relay station corresponding to the communication specifications of the next generation is intended to inform the information of the communication specifications not included in the previous generation. Information about the condition of the cells (cd丨) under it. For example, a plurality of frequency bands (e.g., 20 MHz x 5) can be used in ^8 with respect to one frequency band (e.g., 2 〇 MHz) that can be used in LTE. Therefore, it is conceivable that the base station or the relay station corresponding to the LTE-A can inform the information not addressed in the LTE and for the complex frequency band. However, the wireless communication device that can accommodate both the mobile station of the previous generation and the mobile station of the next generation will be a problem for how to inform the notification of the communication specifications not included in the previous generation. Further, the problem of the above-mentioned notification information is not limited to the situation in which the wireless communication device accommodates the mobile station corresponding to the LTE-compatible mobile station and the LTE-A, but is a problem that generally occurs when a plurality of types of mobile stations are accommodated.

I: Embodiments 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 view showing a mobile communication system according to a first embodiment. The mobile communication system according to the first embodiment includes a wireless communication device and mobile communication devices 2, 3. The wireless communication device 1 can perform wireless communication with the mobile stations of the first type and the second type. The wireless communication device is, for example, a base station or a relay station that transmits wireless communication between the base station 4 and the mobile station. The mobile communication device 2 is a mobile station of the second type, a mobile communication device 3, and a mobile station of the type 1. The mobile communication devices 2, 3 are, for example, wireless terminal devices such as mobile phones or mobile communication* terminal devices. , you have the first generation part la, the second generation part i history #. The first generation unit 1a generates the first class and the second type: the first knowledge information referred to by the mobile station. The mobile station of the second generation unit is not referred to, but the mobile station of the second type will know the information. The transmitting unit 1;;, 俜,, ', the first message, the first generation unit & Further, the transmitting unit 1c transmits (notifies) the second notification information ‘ generated by the (4) to the second notification information 4b of the first notification channel. The mobile communication device 2 has a receiving unit control unit I receiving unit 2a' for receiving information transmitted from the wireless communication device 1 via the first notification channel 4a. Further, the receiving unit 2a receives the second notification information transmitted by the second notification channel. The control unit 2b refers to both the second notification information received by the receiving unit 2a to control communication with the communication device. On the other hand, the mobile communication device 3 does not receive the second notification information although it receives the first notification information. That is, the mobile communication device 3 controls communication with the communication device 1 without referring to the magic notification information. Here, the wireless network can also make wireless communication (4). In this case, the wireless communication device may transmit the information (for example, information indicating the bandwidth of the display band) for connecting to the wireless communication device 1 using the relevant frequency band for each frequency band. Further, it is also possible to include the information on the relationship between the frequency band of the 7F complex number and the type of the mobile station in the second notification information transmission. On the other hand, the mobile communication device 2 can also inform the information (4) 2 that the frequency band of the second type of mobile station can be used among the plurality of frequency bands. Alternatively, the first notification information may be based on the frequency band judged to be usable, and then the band is connected to the wireless communication device 1. The frequency band showing the plural number and the mobile station = relationship information 'for example, the line can be information having the following meaning. The information of the frequency band that can be used by the mobile station of the second type) is the information of the frequency band that is not usable by the second type of mobile station. 3) The frequency band used for the transmission of the information is the second type of mobile. The band that can be used by the station 201129035 4) means that the frequency band used for the transmission of the information is the frequency band that is not usable by the mobile station of the second type, and the wireless communication device 1 can also assign the identification information to a plurality of frequency bands. The identification information can be used to indicate the relationship between the plural frequency band and the type of the mobile station in the second notification information. As the identification information, for example, a cell ID, a unique number within the same cell ID, or the like can be used. When cell Π is used as the identification information, one cell will be assigned a plurality of cell IDs. Further, the mobile station may recognize the plural frequency bands (virtual ground) as different cells. The first notification channel 4a is set, for example, in a plurality of frequency bands. The second notification channel 4b' may be set to a plurality of frequency bands, or only a part of the frequency band. In the latter case, it is conceivable to set it in a predetermined frequency band (e.g., a band at the center on the frequency axis), or a frequency band that can be used in a mobile station of the second type. Further, the second notification channel 4b may be set adjacent to the first notification channel 4a in the radio resource region specified by the frequency and time. Alternatively, the second notification channel 4b may be set adjacent to the synchronization channel for transmitting the synchronization signal. Further, this mobile communication system can be implemented, for example, as an LTEA system. In this case, the mobile station of the first type can be a mobile station corresponding to LTE, and the mobile station of the second type can be realized by a mobile station corresponding to LTE-A. Further, the first notification channel 4a can be realized as a notification channel defined by LTE and LTE-A, and the second notification channel 4b can be realized as an extension notification channel not defined by LTE. Further, in LTE-A, the above-mentioned plural frequency band is sometimes referred to as a component carrier (C〇mP〇nent Carrier' cc) or a carrier component (Carrier Component ' CC). 10 201129035 In the mobile communication device according to the first embodiment, the first notification information and the second notification information are generated by the wireless communication device 1, and the first notification resource system is used for the first and second types of mobile stations. The processor is the second to inform the processor of the second type of mobile station. The first notification information is sent by the first student, Sangdo 4a. The second notification information is transmitted in the second notification channel 4b. Further, the mobile communication device 2 receives the first notification information transmitted by the first notification channel 4 and the second notification information transmitted by the second notification channel 4b. The communication between the wireless communication device and the mobile communication device 2 is controlled based on the received first and second notification information. g P, the notification information that the mobile station of the first type does not refer to (or cannot refer to) but is referred to by the mobile station of the second type, and is different from the notification information that is referred to jointly by the mobile station of the first type and the second type. The channel is informed. Dreams By this, communication control that considers the existence of multiple types of mobile stations can be efficiently implemented. For example, as an implementation of the LTE-A system, it may be considered to inform the notification channel by using the known notification channel, and further, the notification information that should be added by LTE-A can be extended by the notification channel. inform. In this case, the mobile station (LTE_A non-corresponding mobile station) corresponding to LTE can receive the original notification information, that is, the LTE-A system with the efficiency of rear interchangeability can be realized. Further, since the second notification information includes the relationship between the frequency band in which the plural number is displayed and the type of the mobile station, the allocation of the radio resources can be easily controlled. That is, by designating and notifying the frequency band to be used for the mobile station of the second type (or not intended to be used), the second type of mobile station can be easily induced to a part of the band of 201129035. In particular, in the case of the LTE-A system, only one frequency band is used for the mobile station corresponding to LTE, and since the mobile station corresponding to LTE can use a plurality of frequency bands, the above-described induction is intended to improve the utilization efficiency of the radio resources. This is useful. In the second embodiment below, a case where the wireless communication method according to the first embodiment is applied to the LTE-A system is considered. However, the aforementioned wireless communication method can of course be applied to other types of mobile communication systems. [Second Embodiment]

Fig. 2 is a view showing a mobile communication system according to a second embodiment. The mobile communication system according to the second embodiment includes a base station 1, a relay station 200, and mobile stations 300 and 400. This mobile communication system corresponds to the communication specifications of LTE-A. The base station 100 is a wireless communication device that can communicate wirelessly with the mobile stations 300, 400 either directly or through a relay station. The base station is connected to a wired upper network (not shown) and data is transferred between the upper network and the mobile stations 300 and 400. Cells (also known as segments). The base station 100 uses five component carriers (hereinafter referred to as CCs) for wireless communication. The relay station 200 is a wireless communication device that relays wireless communication between the base station 1 and the mobile stations 300 and 400 when there are mobile stations 3〇〇 and 4〇〇. Relay station 200, sometimes referred to as a transit station. The relay station 200 uses five ccs in the same frequency band as the base station 100 in the wireless communication system. The mobile stations 300 and 400 are wireless terminal devices that connect the base station 100 or the relay station 2 to perform wireless communication, for example, a mobile phone or a mobile terminal device. The mobile station 300, in the downward link (the wireless link from the base station 100 or the relay station 200 to the mobile station 3), can simultaneously use up to 5 cc receiving data at the same time 'on the upward link (from the mobile station 3〇〇) The wireless link to the base station 1〇0 or the relay station 200) can use up to 2 CCs to receive data at the same time. On the other hand, the mobile station 400 transmits/receives data using only any H@cc in the downward link and the upward link. Here, in the present embodiment, a mobile station that does not use a plurality of ccs is referred to as an LTE mobile station, and a mobile station that can use a plurality of CCs is referred to as an LTE-A mobile station. The mobile station 3 is an LTE-A mobile station, and the mobile station 400 is an LTE mobile station. At both the base station 1 and the relay station 2, both the LTE-A mobile station and the LTE mobile station can be connected. In addition, in 3GPP, the communication specifications of LTE are defined by the specifications of the 8th edition. The communication specifications of LTE-A are defined by the specifications of the 10th edition. However, all mobile stations corresponding to the 10th edition are not limited to mobile stations (LTE-A mobile stations) that can use a plurality of CCs. That is, there is also a possibility that an LTE mobile station corresponding to the 10th edition exists. Further, in the present embodiment, the mobile station corresponding to the ninth edition is handled as an LTE mobile station in the same manner as the mobile station corresponding to the eighth edition.

Fig. 3 is a view showing a setting example of a component carrier. The base station 1 and the relay station 200 are as shown in Fig. 3, and 5 CCs are used. For the case of two-way communication using Frequency Division Duplex (FDD), ensure CC# 1~# for Down-link (DL) and Up-link (UL) respectively. 5 frequency band. In the following, only CC# 1 to #5 may be referred to as a group of DL bands and UL bands. The frequency bands of CC 13 201129035 of DL and UL are both 20 MHz, and the overall frequency band is 100 MHz. The base station 100 and the relay station 200 perform radio resource allocation (scheduling) for CC #1 to #5, respectively. Further, although the example in Fig. 3 realizes two-way communication by FDD, it is also possible to realize two-way communication by Time Division Duplex (TDD). In this case, on the frequency axis, 5 CC ° is set without distinguishing between DL and UL. In the example of Fig. 3, although the bandwidth of all CCs is set to 2 〇 MHz, it can be set to other bandwidths ( For example 5MHz, 10MHz, 15MHz). Also, the bandwidth of all ccs does not have to be set to be the same. Further, in the example of Fig. 3, the UL radio resource is set to the low frequency side, and the DL radio resource is set to the high frequency side. Since the signal transmission loss of the lower frequency becomes smaller, the UL radio resource is set to the low frequency side, and the transmission power of the mobile stations 300 and 400 can be lowered. However, UL radio resources can also be configured in reverse to DL radio resources. Thus, the mobile station 300 can use a wider bandwidth than the bandwidth of one CC (for example, 20 MHz) by collecting a plurality of CCs in CC #1 to #5 (for example, 40 MHz, 60 MHz, 80MHz 'lOOMHz, etc.) Send/receive data. Here, 'CC# 1 to #5' can be set in any one of the frequency bands of the 800 MHz band, the 2.5 GHz band, the 3.5 GHz band, or the like, or can be dispersed in different complex frequency bands. A plurality of consecutive or discontinuous CC aggregators belonging to the same frequency band are sometimes referred to as carrier aggregation (Carrier Aggregation). On the other hand, cc aggregators belonging to different frequency bands are sometimes referred to as spectrum aggregation. 14 201129035 Figure 4 is a diagram showing the first example of carrier aggregation. In the example of Fig. 4, it is in the 3.5 GHz band, which is used as a band for wireless communication, four non-contiguous 5 MHz wide bands, and three discontinuous 20 MHz wide bands. And by assembling four 5 MHz bands, CC# 2 of 20 MHz width is formed. Also, a band of 20 MHz wide is defined as CC#3. For example, the mobile station 300' can use CC#2 and CC#3 as a 40 MHz band (logically one frequency band) by carrier aggregation. In this case, in reality, the mobile station 300' becomes a band of four 5 MHz wide bands belonging to the 3.5 GHz band and one band of 2 〇 MHz wide. Further, although the frequency band belonging to the 3.5 GHz band is taken as an example in Fig. 4, in other frequency bands such as the 800 MHz band, a band having a frequency wider than 20 MHz may be used in combination. Fig. 5 is a view showing a second example of carrier aggregation. In the example of Fig. 5, a band of 80 MHz wide is prepared in the 3_5 GHz band as a possible band for wireless communication. Moreover, the 80 MHz wide band is divided into four, which are defined as CC#2 to CC#5 of 20 MHz width. For example, the mobile station 300 can use CC#2 'CC#3 as a frequency band of 40 MHz (logically one frequency band) by carrier aggregation. In this case, the mobile station 300 is a part of a continuous 80 MHz wide band belonging to the 3 5 GHz band. Figure 6 is a diagram showing an example of spectrum aggregation. In the example of Fig. 6, in the 2 GHz band, a continuous 20 MHz wide band is prepared as a possible band for wireless communication. Further, in the 3.5 GHz band, a continuous band of 8 〇 MHz wide is prepared as a band that can be used by the wireless communication. Moreover, the 20MHz wide band of '2ghz band' is defined as CC#1, and the band of 15MHz with the 80MHz width of the 3·5ΜΗζ band is divided into four, which are defined as 20MHz wide CC# 2~CC# 5 〇 mobile station 300, for example, CC# 1 to #5 can be used as a 100 MHz band (logically one band) by spectrum aggregation. In this case, the mobile station 300 is actually used. It belongs to the 20MHz wide band of the 2GHz band and the continuous 80MHz band of the 3.5GHz band. Further, as shown in Fig. 4, a complex band domain of a frequency band smaller than 20 MHz which is a 2 GHz band may be aggregated to form CC#1. Figure 7 is a diagram showing the relationship between a mobile station and a component carrier. The mobile station 400, as previously described, is an LTE mobile station. Therefore, the mobile station 400 does not apply carrier aggregation or spectrum aggregation, and uses any of CC #1 to #5 to receive and transmit data. That is, a frequency band of up to 20 MHz wide is used. On the other hand, the mobile station 300 is an LTE-A mobile station. Therefore, since the mobile station 300 applies carrier aggregation or spectrum aggregation, data can be received and transmitted using the complex CCs among cc #1 to #5. That is, data transmission (uplink communication) can be performed in a frequency band of 20 MHz wide or 40 MHz wide. Further, reception of data (down link communication) in a band of '20 MHz wide, 40 MHz wide, 60 MHz wide, 80 MHz wide or 100 MHz wide can be performed. However, in order to identify CC# 1 to # 5 in the cell under the control, the base station 100 and the relay station 200 assign an ID to each cc. As the allocation method of the ID, for example, the following method can be considered, 1) Method of allocating cells 10 to each CC base station In a general LTE system, each base cell is assigned a cell number 16 201129035 ID. In this regard, it is desirable to assign 5 cell IDs to each cell. Next, each of the CCs can be identified by making five cell IDs corresponding to CC#1 to #5. 2) Method for allocating expanded cell IDs for each C C In the general LTE system, 504 cell ids are prepared, and the mobile station uses cell IDs to identify peripheral cells, respectively. If the cell is assigned 5 cell IDs, the design of the mobile communication system, the exhaustion of the cell ID can sometimes become a problem. In this case, more expanded cell Ϊ D than the total number of cells defined in LTE can be defined, and 5 expanded cells RD are assigned to each cell. Next, by making the five expanded cell IDs correspond to CC#1 to #5, each CC 〇〇3 can be identified. The method of assigning a unique number in the cell to each CC will be at least a unique number in the cell, as cc. Number assigned to cC #1~strong s

3. For example, for each cell, give "丨" to CC#. Give "2", give "3" to CC#3, and give "CC#5$*"5,5" the weight of (7)#々. In addition, the cell number, at least as long as it is in the cell, such as P, can also be given a number for the CC of a plurality of cells, for example; the CC of the plurality of cells managed by the base station or the relay station can also be illustrated. A diagram showing a first allocation example of component carrier identification information. The eighth aspect is the one using the first or second method described above. For the base station 100, the pipe of the base station 100 ~ "5" / the cell of the cell # #卜 # 5 'distributed cell ID (or expanded cell 1D) "1" cell ID) "6 oblique to the second cell CC #1 ~ #5 ' allocation Cell ID (or extended fine ID (or split 6" to "1〇". For CC#1 to #5 of the third cell, allocate cell K cell 1D) "U" to "15". X, for the relay station 17 201129035 CC#1~#5 of the cells, allocate cells 1]:) (or expand cell ID) "16" to "20". Fig. 9 is a view showing a second example of allocation of component carrier identification information. In the example of Fig. 9, the method of the third method described above is adopted. The cell numbers "丨" to "5" are assigned to CC#1 to #5 of the first cell managed by the base station. For CC# 1 to #5 of the second cell, the cell number "6" to "1" is assigned. For CC # 1~ # 5 of the third cell, assign the cell number r 丨 〜 to 丨 5. Further, the cell numbers "1" to "5" are assigned to CC #1 to #5 of the cells managed by the relay station 200. Fig. 10 is a view showing an example of the structure of a radio frame. In each of cc#i~#5, the radio frame shown in Fig. 10 is transmitted/received between the base station 1 and the mobile stations 300 and 400, and the relay station 2〇〇 and the mobile station 3〇 (), between 400. However, the structure shown in Fig. 10 is only an example, and the structure of the radio frame is not limited thereto. In this example, the radio frame in the 10ms period includes 1 (H@lms wide sub-frame (sub-frame #0~#9). Each sub-frame contains 2 〇5〇13 wide The trench, that is, the radio frame in the 10ms period, contains 2 trenches (trench # 0~# 19). In the DL radio frame 'in the trenches #〇, #10, the distribution is sent in order to send Primary sync channel for synchronous signals (primary Synchronization)

Channel ''P-SCH) and secondary synchronization channel (sec〇ncjary Synchronization Channel, S-SCH). Further, in the groove #1, in order to transmit the notification information (notification), the physical broadcast channel (PBCH) and the extended entity notification channel are assigned (Extended 18 201129035)

Physical Broadcast Channel, Ε-PBCH). The radio resources in the radio frame are managed by subdividing into time and frequency directions. Use orthogonal frequency division multiplexing access in DL frames (Orthogonal

Frequency Division Multiple Access (OFDMA), and Single-carrier Frequency Division Multiple Access (OFDMA) is used in the UL frame. The wireless message in the area of time χ frequency is assigned to various channels. Regarding the time direction, the groove contains 7 or 6 symbols. An interval signal called a Cyclic Prefix (CP) is inserted in the symbol. In the CP, there are two CPs of different lengths, called a general CP and an extended CP. In the case of a general CP, there are seven symbols in one groove, and the CP is expanded, and six symbols are included in one groove. Regarding the frequency direction, CC contains a plurality of subcarriers. Fig. 11 is a view showing an example of the first allocation of the extended entity notification channel. In the 11th direction, the longitudinal direction is the time axis and the horizontal direction is the frequency axis. Further, in the example of Fig. 11, the case where the general CP is used as the CP, that is, the case where one groove includes seven symbols is displayed.

In the DL frame, the physical control format indicator channel (PCFICH) and the physical hybrid automatic repeat request indicator channel (Physical Hybrid automatic repeat request indicator channel) are assigned to the first symbol of the slot #〇. PCFICH). PCIFH is a channel for notifying the number of symbols allocated by the physical downlink control channel (Physical Downlink Control Channe PDCCH). PHICH is used to feed back the channel of ACK 19 201129035 (ACKnowledgement) or NACK (Negative ACKnowledgement). PHICH is sometimes assigned to the 3rd symbol. Further, the PDCCH described above is allocated to the first symbol of the slot #〇. PDCCH is a channel for transmitting control information of Ll/L2 (Layerl / Layer 2). The PDCCH is also assigned to the second symbol and the third symbol, and the number of symbols of the PDCCH is between 1 and 3 and is variable. Further, the sixth symbol of the slot #0 is assigned with the aforementioned S-SCH, and the seventh symbol is assigned with the aforementioned P-SCH. The P-SCH is a channel in which any one of a predetermined number (for example, three) of the main synchronizing signal series is transmitted. The S-SCH is a channel in which any one of a predetermined number (e.g., 168) of secondary synchronization signals is transmitted. The combination of the P-SCH series and the S-SCH series (for example, a combination of 3 χ 168 = 504 channels) corresponds to the cell ID. As a method of assigning the ID of the CC, the first method described above is adopted, that is, when the cell IDs different from each other are assigned to CC#1 to #5, the P-SCH series and the S-SCH series are different depending on the CC. . Further, as described above, P-SCH and S-SCH are also allocated in the slot #10. However, the P-SCH series transmitted in the groove #10 is the same as the groove #〇, but the S-SCH series transmitted in the groove #1〇 is different from the groove #〇. Further, the first to fourth symbols of the groove #1 are assigned with the aforementioned PBCH, and the fifth to seventh symbols are assigned with the aforementioned E-PBCH. In the wireless message area, the E-PBCH is adjacent to the PBCH in the time direction. PBCH is a notification channel defined by LTE and LTE-A. E-PBCH is a notification channel added to LTE-A. That is, the mobile station 300 of the LTE-A mobile station can detect both the PBCH and the E-PBCH. On the other hand, the LTE mobile station moves 20 201129035 station 400, although the pbch can be detected but the Ε-PBCH cannot be detected. The notification information transmitted in the PBCH includes the information of the CC set by the mobile station 3〇〇, 4〇〇 in order to connect to the PBCH. For example, the information of the pbch notification message includes information of the display bandwidth (for example, 5 MHz, 10 MHz, 15 MHz, 20 MHz, etc.) because the LTE and LTE-A frequency bandwidths are variable. The notification information (extension notification information) sent in the Ε-PBCH includes information on setting the CC for the plural. For example, in order to make scheduling easy, considering the base station 100 or the relay station 200, it is possible to connect the restrictions of the LTE mobile station and the CC that can connect to the LTE-A mobile station. In this case, it is considered that the information indicating the correspondence between the cc#Bu #5 and the type of the mobile station is included in the extension notification information transmission. Thereby, the mobile station 300 of the LTE-A mobile station can know that the CC to be connected can be connected before the base station 1 or the relay station 2, and the connection processing can be made more efficient. As a method of displaying the correspondence relationship between CC#1 to #5 and the type of the mobile station, a method of designating a CC that can connect to the LTE-A mobile station, and a method of specifying a CC that cannot be connected to the LTE-A mobile station can be considered, and a method of designating a CC that cannot be connected to the LTE-A mobile station can be specified. A method of connecting a CC of an LTE mobile station, a method of not being able to connect to a CC of an LTE mobile station, or the like is specified. In terms of expanding the notification information, in order to display the CC, the ID given to each CC can be used. However, the extension notification information does not limit the information showing the correspondence between cc# 1 to #5 and the type of the mobile station, and other information may be included. The S-SCH, P-SCH, PBCH, and Ε-PBCH, as shown in Fig. 11, are not allocated to one CC (subcarrier) as a whole, but may be allocated only to a part of the frequency (subcarrier). Such as the frequency assigned to the center of the CC. 21 201129035 The vicinity of the non-CC realm is allocated to the frequency near the center of cc, in order to make channel detection by the mobile stations 300, 400 easier. The frequency assigned to the E-PBCH may be the same as the frequency assigned to the PBCH, or may be different. Further, the DL frame transmits a reference signal (RS) of the known pilot signal using a portion of the resource other than the radio resource for the channel. The mobile stations 300, 400 use the reference signal to determine the received power or reception quality. Fig. 12 is a view showing a second allocation example of the extended entity notification channel. The assignment example of Fig. 12 is the same as the example shown in Fig. U except for the setting position of the E-PBCH. In the example of Fig. 12, E-PBCH is assigned to the fourth to fifth symbols of the groove #0. On the radio resource area, the E-PBCH is adjacent to the S-SCH in the time direction. The frequency assigned to the E-PBCH may be the same as or different from the frequency assigned to the S-SCH.

Figure 13 is a diagram showing a third allocation example of the extended entity notification channel. The assignment example of Fig. 13 is the same as the example shown in Figs. 11 and 12 except for the setting position of the E-PBCH. In the example of Fig. 13, E-PBCH is assigned to both the fourth to fifth symbols of the groove #〇 and the fifth to seventh symbols of the groove #1. In the radio resource area, the E-PBCH is adjacent to the S-SCH and PBCH in the time direction. The frequency assigned to the E-PBCH may be the same as or different from the frequency assigned to the S-SCH and the PBCH. Thus, by increasing the amount of radio resources allocated to the E-PBCH, more extended notification information can be sent. The wireless resources assigned to the E-pBCH may also be made variable in response to the amount of information to be transmitted. Further, as shown in the 22nd 201129035 11 to 13, the E-PBCH is more easily detected by the E-PBCH of the mobile station 300 by causing the E-PBCH to be adjacent to at least one of the synchronization channel and the PBCH in the time direction. However, it can also be set to be adjacent to the frequency direction, not the time direction. Further, the E-PBCH may be set not to be adjacent to either the synchronization channel or the PBCH, and the 14th figure is a diagram showing the fourth allocation example of the extended entity notification channel. The assignment example of Fig. 14 is the same as the example shown in Figs. 11 to 13 except for the setting position of the E-PBCH. In the example of Fig. 14, the E-PBCH is assigned to the seventh symbol of the groove #1. On the radio resource area, the E-PBCH is not adjacent to the PBCH. The frequency assigned to the E-PBCH may be the same as or different from the frequency assigned to the PBCH. Fig. 15 is a view showing a fifth allocation example of the extended entity notification channel. The assignment example of Fig. 15 is the same as the example shown in Figs. 11 to 14 except for the setting position of the E-PBCH. In the example of Fig. 15, the E-PBCH is assigned to the fourth symbol of the groove #0. On the radio resource area, the E-PBCH is not adjacent to the S-SCH. The frequency assigned to the E-PBCH may be the same as the frequency of the S-SCH, or may be different. Figure 16 is a diagram showing a sixth allocation example of the extended entity notification channel. The assignment example of Fig. 16 is the same as the example shown in Figs. 11 to 15 except for the setting position of the E-PBCH. In the example of Fig. 16, E-PBCH is assigned to the sixth symbol of the groove #1. On the radio resource area, the E-PBCH is not adjacent to the PBCH. The frequency assigned to the E-PBCH may be the same as or different from the frequency assigned to the PBCH. In the above, from the 11th to the 16th, the case where the general CP is used as the 23 201129035 CP (1 case where the groove includes 7 symbols) is taken as an example, but the case where the Cp is expanded as the CP is used (1 groove) In the case of a 6-symbol), the E-PBCH can be set in the same way. In this case, for example, the method in the figure is based on the fifth to sixth symbols of the groove #1, and the method in the second figure is the fourth symbol of the groove #〇, in the third figure. The method is based on the 4th symbol of the groove #〇 and the 5th to 6th symbols of the groove #丄, and the method of Fig. 14 is to assign the E-PBCH to the 6th symbol of the groove #丨.

A) A converter, a frequency converter, a band pass filter, a power amplifier, etc. The frequency band to be transmitted is instructed by the terminal control unit 319. 20 is a sequence diagram showing a first connection example from the mobile station to the base station. This sequence is shown as a case where the mobile station 300 of the LTE-A mobile station is connected to the base station 100. The mobile station 300 is connected to the base station 2 In the case of 〇〇, the same order is also obtained. (Step S11) The base station 100 transmits the synchronization signal by using the P-SCH and the S-SCH of each of cc#1 to #5. Using cc# 1~#5 In the case of 1D as the cell ID, a different synchronization signal is transmitted every CC. In the case of the cell of the base station, the synchronization signal is transmitted to each cell. Similarly, the relay station 2〇〇 also transmits a synchronization signal. (Step S12) The mobile station 300 synchronizes with the base station 1 based on the timing of detecting the radio frame of each cell based on the synchronization apostrophe transmitted by the base station 1 。. When the timings of the CC# 1 to #5 radio frames are the same, it is not necessary to perform timing detection for all CCs. Similarly, the mobile station 300 acquires synchronization with the relay station 2. (Step S13) The base station 1 transmits the reference signal of the pilot signal by cc#丨~#5. The reference signals sent by CC# 1~#5 can all be the same signal. Similarly, the relay station 2〇〇 also transmits a reference signal. (Step S14) The mobile station 3 detects the received power from the base station 100 for each cell based on the reference transmitted by the base station 1〇〇. Receiving power can also be used for any one of the CC measurements, and can also be directed to a plurality of CCs. In the case of the former, the frequency band to be measured may be determined in advance. In the latter case, the maximum or average value of the received power of the complex CC can also be defined as the received power from the base station 100. Similarly, the mobile station 300 measures the received power from the relay station 200. (Step S15) The mobile station 300 selects the cell to which the mobile station 300 is to be connected based on the received power measured in step S14. Ideally, the mobile station will choose to receive the cells with the most power. Here, cells under the base station 100 are selected.

(Step S16) The base station 1 transmits (notifies) the notification information by using the individual PBCHs of CC #1 to #5. Further, the extension notification information is transmitted (notified) by at least one of the E-PBCHs placed in CC#1 to #5. (Step S17) The mobile station 300 confirms the cc° (step S18) mobile station 300 that the LTE-A mobile station can connect to in the CC# 1 to #5 based on the extension notification information transmitted (notified) by the base station 100. The CC selected for use in the random access is selected from the CCs that have been confirmed to be usable by the LTE-A mobile station in step S17. When there are multiple candidates for CC, you can also select any one of them or choose the one with the largest received power. Further, in the example of the sequence of Fig. 20, although the CC to be used is selected after selecting the cells to be connected, the cells and the CC can be simultaneously selected. For example, the reception power of the CC of all the surrounding cells detected is measured without being limited to one cell, and among these CCs, a CC in which the LTE-A mobile station may be connected and receives a large power may be selected. Further, before selecting cell 35 201129035, it is possible to confirm the cc to which the LTE-A mobile station is connected to the surrounding cells, and to measure the received power of the cc, and select the cc having a large reception power. (Step S19) The mobile station 300 confirms the information (e.g., the information indicating the bandwidth of the bandwidth) to be connected to the c c corresponding to the notification information selected in the step S18. Further, a random access preamble is transmitted to the base station 100 at the PRACH of the radio frame set in the selected CC. (Step S20) The base station 1 is a CC that receives a random access preamble, and is a CC that the LTE-A mobile station may connect to, and if there is enough space for accommodating the radio resources of the mobile station 300, The connection of the mobile station 300 is allowed. When the connection is allowed, the base station 100 transmits a random access response indicating that the connection is permitted by the PDSCH of the DL radio frame set to receive the CC of the random access preamble. At this time, the base station 100 allocates the UL radio resource for the step S21 to the mobile station 300. (Step S21) The mobile station 300 broadcasts the progress of the predetermined message to the base station 1 in order to confirm whether or not the communication can be normally performed by the UL radio resource (PUSCH) allocated in the step S20. (Step S22) The base station 100 is to confirm whether or not the progress broadcast is normally received. Further, as a response message, a contention resolution indicating whether or not reception is possible is transmitted to the mobile station 300 on the PDSCH. As described above, the mobile station 300 of the LTE-A mobile station can confirm the CC that can be used by the LTE-A mobile station before random access by referring to the extension notification information by reception. Therefore, the connection of the CC that the LTE-A mobile station cannot use is not attempted, and the procedure of wasting random access can be suppressed. Further, since the CC that can be used by the LTE-A mobile station can be confirmed in advance, the CC of the received power 36 201129035 can be measured. Therefore, the load of the processing of the mobile station 300 can be alleviated.

On the other hand, the mobile station 400 of the LTE mobile station cannot refer to the extended announcement information. Therefore, even if the base station 100 or the relay station 200 restricts the CCs usable by the LTE mobile station, it is impossible to confirm whether any of the CCs is a CC usable by the LTE mobile station before random access. Therefore, random access failures occur. Fig. 21 is a sequence diagram showing a second connection example from the mobile station to the base station. This sequence is shown as a case where the mobile station 4 of the LTE mobile station is connected to the base station. The case where the mobile station 400 is connected to the relay station 2 is also performed in the same order. (Step S31) The base station 1 transmits the synchronization signal by p_SCH and S-SCH of cc#Bu#5, respectively. In the case where the base station 1 manages a plurality of cells, a synchronization signal is transmitted for each cell. Similarly, the relay station 2〇〇 also transmits a synchronization signal. (Step S32) The mobile station 4 detects the timing of the radio frame for each cell based on the synchronization signal transmitted from the base station 1 and synchronizes with the base station 1 . When the cell ID is used as the CC2ID, the mobile station 400 may recognize CC# 1 to #5 (virtual) as mutually different cells. Similarly, the mobile station 400 acquires synchronization with the relay station 2. (Step S33) The base station is transmitted as a reference signal of the pilot signal by cc#卜#5. Similarly, the relay station also sends reference signals. (Step S34) The mobile station Yang measures the reception power from the base station for each cell and every cc based on the reference of the base station. Similarly, the mobile station_ measures the received power from the relay station 200. (Step S35) The mobile station is configured to select the cell to be connected by the mobile station based on the "received power" measured in the step S34. Ideally, the mobile port 4〇〇 will choose to receive the cells with the most power. Here, the cells selected under the genus of the base station 100 are selected. In the case of the base station (step S36), the information is sent (informed) by cp#1~#Mgj other p叱η. (Step S37) The mobile station 4 selects CCs for random access from CC#1 to #5 of the cells selected in the step S35, and can select any of CC, CC#1 to #5. Hg), you can also choose to receive the most power! One. Further, when the mobile stations 400 recognize CC#1 to #5 (virtually) as mutually different cells, it is conceivable to select the cells and select cc based on the received power. (Step S38) The mobile station 300 confirms a message included in the notification information corresponding to the CC selected in the step S37, and is used to connect to the CC (for example, information showing the bandwidth). The random access preamble is transmitted to the base station 1 by the prACH of the UL radio communication frame set in the selected CC. However, the selected 2CC system is a CC that cannot connect 1; 1 £. Step S39) The base station 1 is configured to reject the connection of the mobile station 400 when the CC of the random access pre-matrix received by the LTE mobile station is not connected. In the case of rejecting the connection, the base station 100. Send a random access response indicating that the connection is rejected by the PDSCH of the DL radio frame of the CC of the random access preamble. Also, the base station does not perform the pre-random access 38 201129035. Respond. (Step S40) Mobile station 400, when receiving the display Determining the random access response of the link, or determining that the random access fails after receiving the random access response and not receiving the response within the specified time. Then, the mobile station 400 selects the cell selected in step S35. (Other than CC) (Step S41) The mobile station 400 confirms a message including the notification information corresponding to the CC selected in the step S4, and is used to connect to the CC. The PRACH of the UL radio communication frame of the selected CC transmits a random access preamble to the base station 100. Here, the selected CC system is a CC connectable to the LTE. (Step S42) Base station 1〇〇 When the CC receiving the random access preamble is a CC connectable by the LTE mobile station, and there is a space sufficient to accommodate the radio resources of the mobile station 400, the connection of the mobile station 400 is allowed. When the connection is allowed At the time, the base station 100 transmits a display permission to connect the random access response by using the PDSCH of the DL radio communication frame of the CC that receives the random access preamble. At this time, the base station 1〇〇 is used for the step S43. UL wireless resource allocation The mobile station 400. (Step S43) The mobile station 400 transmits the progress transmission to the base station 1 in order to confirm whether or not the communication can be performed normally, in the UL radio resource (PUSCH) allocated in the step S42. (Step S44 The base station 1 将 will confirm whether the progress transmission is normally received. Then, as the response message, the contention resolution indicating whether or not reception is possible is transmitted to the LTE mobile station 400 by the PDSCH. Thus, the mobile station of the LTE mobile station 4 ( ), because it is impossible to refer to the extension 39 201129035 to inform the information, so 'Before random access, it is impossible to confirm [the cc that can be used by the mobile station. Therefore, random access has the possibility of failure. Further, since the CC that can be used by the LTE mobile station cannot be confirmed, it is not possible to narrow down the CC in which the received power should be measured in advance. Next, the relationship between CC#Bu#5 and E-PBCH will be explained. Fig. 2 is a diagram showing an example of the first transmission and reception of the extension notification information. In the example of Fig. 22, the base station 100 or the relay station 200 controls to use CC #1 to #3 for the LTE mobile station and #4 to #5 for the LTE-A mobile station. Further, the base station 100 or the relay station 200 is provided with PBCH and E-PBCH in all of CC#1 to #5. The PBCH at each CC will send a notification message containing the information used to connect the CC. The notification information transmitted in the PBCH may be different depending on the CC. ◎ The extension notification information including the information indicating the relationship between the CC# 1 to #5 and the type of the mobile station is transmitted in each E-PBCH. The extension information sent by E-PBCH can also be the same for all CCs. In this case, the terminal of the LTE-A mobile station receives the extension notification information transmitted by the E-PBCH of any of CC #1 to #5. From the received extension notification information, it is known that #4 and #5 are CCs that can be used in the LTE-A mobile station. Moreover, one of #4, #5 can be selected as the CC for random access. Which of #4 and #5 should be selected can be judged based on the received power measurement result. In the example of Fig. 22, the mobile station 30 选择 selects the CC# 4 by referring to the extension notification information notified by cc#4m. When CC#4 is selected as the cc for random access, the mobile station 3 refers to the notification information sent by the PBCH of CC#4, and is set to the UL wireless signal set in 〇(:: 40 201129035 #4 The PRACH of the frame transmits a random access preamble, whereby the procedure of random access between the base station 100 or the relay station 200 and the mobile station 3〇〇 can be started. Thus, in the example of Fig. 22, since all ccs E-PBCH is provided. 'As long as you refer to any CC', you can know the CC that can be used by the lte_a mobile station. In addition, since the mobile station 300 is an LTE-A mobile station, CC# 4 and #5 can be collected and used for data. In this case, in the case of random access, one CC (CC# 4) is first used for the procedure. Thereafter, the connection between the base station 1 or the relay station 200 and the mobile station 300 is established. At the time, based on the control of the base station 100 or the relay station 200, other CCs (CC#5) that can be used by the LTE-A mobile station can be used. Also, the base station 100 or the relay station 200 can already use cc# 1~# Among the 5, the CCs that can be used by the LTE-A mobile station are dynamically changed in response to the communication status. In this case, the base station 100 or the relay station 200 dynamically changes the content of the extension notification information transmitted by the E-PBCH. Fig. 2 is a diagram showing the second transmission and reception example of the extension notification information. In the example of Fig. 23, the base station 1〇〇 or the relay station 200 is provided with PBCH in all CC#1 to #5, and E-PBCH is set only in CC#4 and #5 which can be used by the LTE-A mobile station. In the PBCH of each CC, the transmission includes The notification information for connecting the information used by the CC. In the E-PBCH of CC #4, #5, the extension information indicating the information including the relationship between CC# 1 and #5 and the type of the mobile station is transmitted. In this case, the mobile station 300 of the LTE-A mobile station receives the extension notification information sent by the E-PBCH of one of the CC #4 and #5. 41 201129035 From the reception extension notification information, it can be known that cc#4, #5 is a CC that can be used by the mobile station. Moreover, one of cc#4 and #5 is selected as the CC for random access. Thus, in the example of Fig. 23, because only the LTE_A mobile station The E-PBCH can be set by using the CC, so radio resources can be saved. In addition, if the ccs that can be used only in the LTE_A mobile station is determined in advance, E_P In the BCH, the mobile station 300 can determine that the CC system that can detect the E-PBCH can be used by the LTE-A mobile station. In the case, the extension of the E-PBCH transmission of cc#4, #5 informs the information ' It may not contain information about other ccs. Also, 'base station 100 or relay station 200, E-PBCH can be set only on one of cc#4 and #5. In other words, E-PBCH may be provided in at least one of ccs that can be used by the LTE_A mobile station. Further, the CC in which the E-PBCH is set is referred to as the basic CC or the basic band, and the other ccs are referred to as the extended cc or the extended band. Fig. 24 is a view showing an example of the third transmission and reception of the extension notification information. In the example of Fig. 24, the base station 1 or the relay station 200 is provided with PBCH in all of CC#1 to #5, and only in the center position CC#3 of CC# 1 to #5 on the frequency axis is set to E. -PBCH. At the PBCH of each CC, the notification information including the information used to connect the CC is transmitted. In the E-PBCH of CC#3, the extended notification information indicating the information including the relationship between CC#1 to #5 and the type of the mobile station is transmitted. In this case, the mobile station 300 of the LTE-A mobile station receives the extension notification information transmitted by the E-PBCH of CC#3. From the received extension notification information, it can be seen that CC#4 and #5 are CCs that can be used for the LTE-A mobile station. And 42 201129035, and one of CC#4 and #5 is selected as the random access & therefore, in the example of Fig. 24, since only the LTE_A mobile station can use the cc to set the E-PBCH. Therefore, the wireless f source can be saved. Further, since the mobile station is fine only by referring to a predetermined cc (for example, CC located at the center of cc#丨 to #5 on the frequency axis), the processing of the mobile station 300 can be simplified, and the processing load can be reduced. According to the mobile communication system according to the second embodiment as described above, the base station 100 or the relay station 200 can restrict the connectable CCs depending on the type of the mobile station. Therefore, it is easy to schedule the LTE-A mobile station and the LTE mobile station in a mixed environment. In addition, it is easy to allocate broadband wireless resources to the LTE A mobile station. Further, the LTE-A mobile station can know the available cc before connecting to the base station 100 or the relay station 200 by referring to the extension notification information. Therefore, even in the case where the CC connectable according to the type of the mobile station is restricted, the connection processing can be smoothly performed. Further, the LTE-A mobile station can reduce the c C of the received power when the cell selection or the C C is selected, and the processing load can be reduced. Plus, the processing time can be shortened when cells are selected (including when they are transferred). For example, the LTE-A mobile station detects three peripheral cells in advance, and two of the five CCs of each cell are assumed to be allocated to the LTE-A mobile station. In this case, it is necessary to measure the received power of 5x3 = 15 CCs without referring to the extension notification information and selecting the CC that receives the large power as much as possible. On the other hand, when the reference extension information is used to exclude the CC that cannot be used by the LTE-A mobile station, it is only necessary to measure the received power of 2x3=6 CCs. That is, the processing of the LTE-A mobile station can be reduced to about two-fifths. 43 201129035 Of course, the extension notification channel not only displays the information of the correspondence between the cc and the type of the mobile station, but also can be used to send various information to be notified to the LTE-A mobile station. Alternatively, a new notification channel that is not defined in LTE may be referred to by a name other than the "expansion notification channel". For example, one of the conventional notification channel and the extension notification channel may also be referred to as a first notification channel, and the other may be referred to as a second notification channel. Only the principles of the present invention are shown with respect to the above. Furthermore, most of the modifications and changes are possible for the person engaged in the occupation, and the present invention is not limited to the correct configuration and application examples described above, and all the modifications and equivalents are provided by the present invention. The scope of the appended claims and their equivalents are considered to be within the scope of the invention.
