The technical field TO WHICH the INVENTION RELATES

Described here is a variant embodiment of the invention relates to a radio communication device, radio communication system and method of radio communication.

PRIOR art

The number of radio communication systems, such as a mobile telephone system and network radio urban scale (WAN, MAN), are currently in use. To achieve further enhance speed and larger capacity of radio communication, is constantly active discussion of the radio technology of the next generation.

For example, in the Project third generation partnership (3GPP), a standards organization, proposes a communication standard called Project long-term development (LTE) enables communication using the frequency band of 20 MHz maximum. In addition, in the LTE communication systems proposed next generation communication standard, referred to as "LTE advanced" (LTE-Advanced, LTE-A), which allow connection with the use of five frequency bands (i.e. the frequency band of 100 MHz) to 20 MHz maximum (e.g., see reference 1 and non-patent literature 2).

In LTE-A, the number of frequency bands to be used, it is proposed that subject to the dynamic change in accordance with the traffic (e.g., see non-patent literature 3).

In addition to t�, in the radio system from one radio communication device (e.g., mobile station) to another communication device (e.g., base station) that manages the allocation of radio resources can be random access. Random access from the mobile station to the base station is performed, for example, at the point in time when (1) a first mobile station accesses the base station, (2) to the base station requesting allocation of radio resources used for data transmission, and (3) synchronization is established during the data reception from the base station, and (4) achieves synchronization with the mobile target base station during a handover.

Random access includes random access competition (conflict resolution) and random access without competition (see, e.g., section 10.1.5 non-patent literature 4, and section 5.1 non-patent literature 5). In the case of random access from the mobile station to the base station in a random access contention, the mobile station randomly selects a signal sequence from among the totality of the signal sequence and transmits it to the base station in the form of a random access preamble. In random access without competition, the base station notifies the mobile�optimum station information in which is set the signal sequence, and the mobile station transmits the signal sequence in accordance with the notification from the base station in the form of a random access preamble.

Description of embodiments of the invention

Preferred embodiments of the present the image�message will now be described in detail below with reference to the accompanying drawings, on which same reference items refer to the same elements throughout the description.

The FIRST VARIANT of IMPLEMENTATION

Fig. 1 shows an illustration of a radio system according to the first variant implementation. Radio system according to the first variant implementation includes a wireless device, shows the positions 1 and 2. Unit 1 and radio 2 to perform communication by using a set of frequency bands. This radio system is implemented, for example, in the form of a system of LTE-A. In the system of LTE-A, each set of frequency bands may be referred to as "component carrier" (CC).

The radio communication device 1 performs allocation of radio resources. Under control of the radio communication device 1, the radio communication device 2 performs data transfer between the device 1 radio (or other communication device) and their own equipment. For example, the radio communication device 1 is implemented as a base station or a relay station, and radio communication device 2 is implemented in the form of subscriber stations. Or, alternatively, the radio communication device 1 may be implemented as a base station, and radio communication device 2 may be implemented as a relay station. Device 1 and radio 2 can be a stationary communication device or the mobile�ful radio.

The radio communication device 1 comprises a unit 1a controls and sending unit 1b. Unit 1a control sets the frequency band #1 as the frequency band used for the random access procedure using the radio communication device 2. Unit 1a, the controls are further selects a frequency band #2 as the frequency bands used to transmit data via the radio communication device 2. Sending unit 1b transmits a control message related to random access, the radio communication device 2 using the frequency band #1. In this control message is inserted identification information indicating the frequency band #2. Identification information (e.g., unique identifier) pre-approved by the set of frequency bands, respectively.

The Radiocommunication device 2 comprises a receiving unit 2a and unit 2b management. The receiving unit 2a receives the control message relating to the random access, the radio communication device 1 by using the frequency band #1. The control unit 2b confirms the identification information included in the adopted control message, and controls the radio communication device 2 to perform data transmission by using the frequency band #2, the specified identification information. Examples of the target arbitrary �access and partner data to the radio communication device 1 includes a radio communication device 1. It is noted that in the case of performing a handover from the radio communication device 1 and another communication device, the target random access and handover data is a wireless communication device as a target of the handover.

As described above, relative to a random access, the radio communication device 2 performs random access without competition or random access competition. In the case of random access without competition, for example, it is believed that the message (Msg0) to set the signal sequence of the preamble random access response (Msg2) to the random access request in response to the request of the preamble (Msg1) random access is assumed to be used as a control message. In the case of random access competition is considered that the response to the request random access is to be used as a control message.

When receiving a control message including identification information, by using the frequency band #1, the radio communication device 2 can continue the subsequent random access procedure by using the frequency band #2. In the case where the frequency band #2 is in an inactive state, at the time of admission Manager �of oobmine, including the identification information, the radio communication device 2 can change the state of the frequency band #2 to the active state. On the other hand, at the time of receiving the control message including the identification information, the radio communication device 1 can change the state of the frequency band #2 to the active state. In this case, the devices 1 and 2 of the radio communication is not required to transmit and receive a control message to change the state of the frequency band #2 to the active state.

In the above-described radio communication system according to the first variant implementation of the radio communication device 1 selects the frequency band #2 as the frequency bands used to transmit data via the radio communication device 2. During the execution of the random access procedure, by use of the frequency band #1, the radio communication device 1 transmits to the radio communication device 2 of the control message including identification information indicating the frequency band #2. On the other hand, during the execution of the random access procedure, by use of the frequency band #1, the radio communication device 2 receives from the radio communication device 1 of the control message including identification information indicating the frequency band #2. The radio communication device 1 then we have managed� data transmission by using the frequency band #2, specified identification information.

This process allows the radio communication device 1 to issue a resolution regarding the use of the frequency band #2, different from the frequency bands #1, used during the startup of the random access procedure, the Radiocommunication device 2 during the random access procedure. Thus, the radio communication device 1 implements a plan for providing cross-carrier during the random access procedure. Accordingly, after the random access procedure, a radio communication device 1 should not separately perform the procedure for issuing permits for the use of the frequency band #2 to the radio communication device 2, and performs effectively manage the use for a set of frequency bands.

In the variants of implementation from the second to the fourth case where the radio communication method according to the first embodiment of the applied to the mobile communication system of LTE-A will be further described in detail below. It is noted that the radio communication method according to the first variant implementation is applicable to a mobile communication system using the communication method that is different from the LTE-A, or the system fixed radio communications.

The SECOND VARIANT of IMPLEMENTATION

Fig. 2 shows an illustration of a mobile communication system according to a second Varian�the implementation. The mobile communication system according to a second embodiment of the includes a base station 10, mobile station 20 and the relay station 30. This mobile communication system allows the radio using five component carriers maximum.

Base station 10 is a radio communication device that performs communication with mobile station 20 directly or via the relay station 30. Base station 10 is connected to (leading) the host station (not shown) wired connection, and transmits the user data between the wired communication section and a radio section. The base station 10 manages radioresource lines of communication between the base station 10 and mobile station 20, and in addition - radioresource lines of communication between the base station 10 and relay station 30.

The mobile station 20 is a radio terminal (radio terminal), which accesses the base station 10 or the relay station 30, and performs radio communication. As the mobile station 20, for example, use a mobile phone with a handset or a portable information terminal device. The mobile station 20 performs random access, and establishes synchronization with the base station 10 or the relay station 30, and then transmits and receives �data.

Relay station 30 is a communication device that relays data transmission between the base station 10 and mobile station 20. Relay station 30 may be a fixed communication device or mobile communication device. Relay station 30 can perform random access to the base station 10 and set in sync with her. In addition, the relay station 30 manages radioresource lines of communication between the relay station 30 and mobile station 20.

The following description of the second embodiment will be described by the random access procedure performed between the base station 10 and mobile station 20. Even between the base station 10 and relay station 30, and between the relay station 30 and mobile station 20 executes the same procedure random access.

Fig. 3 shows a sequence diagram of signals illustrating a random access procedure with the competition. The following section will now be described the case where the random access procedure is performed in a component carrier of only one component. The sequence shown in Fig. 3, includes the following steps:

(Step S11) of forming the data to be transmitted in uplink (UL), Moby�of obayatelnaya, charming station 20 selects one arbitrary signal sequence from a set of pre-defined signal sequences. The mobile station 20 then transmits the preamble (Msg1) random access, which includes the selected signal sequence to the base station 10 using a physical random access channel (PRACH). At this time, PRACH, multiple mobile stations may transmit the same signal Msg1 sequence, i.e. it can be called the conflict of random access;

(Step S12). Upon detection Msg1 on PRACH, the base station 10 measures the temporal distribution of transmission in the UL to the mobile station 20 and simultaneously allocates the UL radio resource of the mobile station 20. The base station 10 then transmits a response (Msg2) to the request random access, which includes information for synchronizing the temporal distribution of UL or information indicating the allocated UL radio resource. In the case that caused the conflict of random access, the mobile stations, which transmit Msg1, take Msg2, respectively;

(Step S13) When receiving Msg2, the mobile station 20 transmits a scheduled transmission (Msg3), which includes identification information of the mobile station 20, the base station 10 using the UL radio resource allocated by the base station 10. In the case that caused the conflict of random access, the mobile stations, which transmit Msg1 (i.e. take Msg2), transmit Msg3, respectively. In this case, sosaku�sequence of transmitted groups Msg3 interfere with each other on the same radio resource;

(Step S14), the base station 10 detects Msg3 on the UL radio resource allocated in step S12. On the basis of identification information included in Msg3, the base station 10 identifies the mobile station 20, which performs random access. As a result, the base station 10 transmits a message (Msg4) conflict resolution indicating that the mobile station 20 is identified, the mobile station 20. The mobile station 20 then establishes synchronization between the base station 10 and its own station, and enables data transfer.

It is noted that in case of conflict, the random access identification information of the mobile station as the transmission source cannot be retrieved from Msg3. In this case, base station 10 transmits a message indicating that the called random access conflict. After waiting for a random time, the mobile station 20 that receives the message, returns to step S11 and performs the random access procedure again. When the conflict is resolved, the mobile station 20 establishes synchronization between the base station 10 and its own station, and enables data transfer.

Fig. 4 shows a sequence diagram illustrating a random access procedure without competition. In the next section�Le will now be described the case, where the random access procedure is performed in a component carrier of only one component. The sequence shown in Fig. 4, includes the following steps:

(Step S21). When the data transmission in downlink (DL), reach the base station 10, the base station 10 selects one of the unused signal sequence from a set of pre-defined signal sequences. The base station 10 then transmits to the mobile station 20 notice (Msg0) specialized in the preamble to indicate the selected signal sequence. At this time, the base station 10 performs the control with the exception of the set of mobile stations so as not to allocate the same signal sequence simultaneously;

(Step S22) Within a specified period (period of validity) from the reception Msg0, the mobile station 20 transmits Msg1, including the signal sequence specified by Msg0, to the base station 10 using the PRACH. Here, as the preset signal sequence is allocated exclusively (exclusively) mobile station 20 during the validity period, the random access conflict is not invoked:

(Step S23) Upon detection Msg1 on PRACH, the base station 10 allocates the radio resource UL mobile �the stage 20. The base station 10 then transmits the Msg2 includes information indicating the allocated UL radio resource, the mobile station 20. Data transfer is then made possible between the base station 10 and mobile station 20. Since the random access conflict is not called, the base station 10 is not required to transmit and receive Msg3 and Msg4 in random access without competition.

Random access competition occurs, for example, at the point in time when (1) the mobile station 20 first time accesses the base station 10 and at the time when (2) the mobile station 20 makes a request for the allocation of radio resources to the base station 10. Random access without competition, for example, (3) when receiving data from the base station 10, in the moment of time when the mobile station 20 establishes synchronization with the base station 10, and (4) when performing a handover to the base station 10 from another base station, at time when the mobile station 20 establishes synchronization with the base station 10.

It is noted that if the subject performing random access without competition (for example, at the time of establishing synchronization during a handover, or when the mobile station 20 receives data from the base station 10) if a separate �Ignalina sequence is used in the base station 10, is transmitted and received Msg0, not including a dedicated preamble. In this case, random access is performed to the competition. In the case of a handover base station 10 to transmit the service transmits Msg0 to the mobile station 20. According to a second embodiment of the, it is believed that the base station 10 and mobile station 20 performs a random access procedure without competition.

Fig. 5 shows an illustration of a component carrier in which radio communication is performed. As described above, the base station 10 and mobile station 20 using five component carriers (CC#1 to #5), thereby performing radio communication. All frequency bands for CC #1 to #5 may be the same each other or different from each other.

The component carrier CC #1-#5 are given the pointer carrier (CI) in 3 bits as identification information, respectively. Here, 0b000 (0) means CC#1, 0b00l (1) means CC#2, 0b010 (2) means CC#3, 0b011 (3) means CC#4, and 0b100 (4) means CC#5. Here 0b101 (5) 0b110 and (6) are unused (reserve value). As described later, 0b111 (7) can be used to specify its own component carrier.

The base station 10 sets for CC #1-#5 of their condition in each mobile station. Based on the States of CC #1-#5, the mobile station 20, the control�et processing of the reception signal for each component carrier. On the basis of their States, for example, CC#1-#5 are classified as "configured but deactivated CC", "configured and activated CC", and "the set of PDCCH monitoring".

"Configured but deactivated CC" is the component carrier in which the data transmission is not currently running, and which is able used (inactive). In a component carrier in the dormant state, the mobile station 20 is not required to monitor any channel from the physical control channel downlink (PDCCH) in which control data are transmitted, and a physical shared channel downlink (PDSCH) in which the transmitted data signal. That is, mobile station 20 may stop the processing of a reception signal for the frequency band.

"Configured and activated CC" is the component carrier (active), which is currently transferring data. Using the component carrier in the active state, the mobile station 20 performs at least the processing of the reception signal related to PDSCH to the mobile station 20.

"The set of PDCCH monitoring" is in the active state and is the set of component carriers, which may be installed PDCC in relation to mobile station 20. The mobile station 20 monitors the PDCCH using the component carrier included in this set. In the case where the length of the PDCCH signal is not constant, the mobile station 20 blind decode a PDCCH. Specifically, the mobile station 20 is experiencing a number of decodings according to the duration of signal, thereby extracting the control data. It is noted that the set of PDCCH monitoring" is defined as a subset of the "configured and activated CC" and receive processing PDCCH must be implemented by all "configured and activated CC" in some cases. In this case, the set of PDCCH monitoring" and "configured and activated CC" mean one and the same set.

In addition, the component carrier with PDCCH may be different in each mobile station. Base station 10 may set the CC part #1-#5 as a "tie-in component carrier" (ACC). ACC is a component carrier subject to monitoring by the mobile station. If ACC is installed, the ACC switched on, at least in the set of PDCCH monitoring". Component carrier set as the ACC can be set in each cell or in each cell station.

To perform two-way communication, the base station 10 and mobile station 20 may use the duplex mode before�Chi with time division (TDD) or full-duplex transmission with frequency division (FDD). In the case of TDD, a single frequency band is set for each CC. In the case of FDD, installed a pair of frequency bands for UL and frequency bands for DL for each CC. As mentioned hereinafter, the random access procedure may be performed in any case from the case where the frequency band is divided into a frequency band for UL and bandwidth for DL, and the case where the frequency band is not divided into a frequency band for UL and bandwidth for DL.

On command from the control unit 14, the scheduler 12 performs allocation (scheduling) of radio resources for a mobile station 20 and the relay station 30. During the random access procedure, for example, the scheduler 12 allocates the radio resource UL mobile station 20, and notifies the radio communication unit 11 of the allocated UL radio resource.

The wired communication unit 13 is a communication interface unit that performs wired communication with the host station. The wired communication unit 13 receives from the host station user data for the mobile station 20. According to the scheduling by the scheduler 12, the accepted user data is sent to the mobile station 20. The wired communication unit 13 further transmits the user data extracted by the radio communication unit 11, the host station.

To�particular, unit 15 of the control plane receives the control data extracted by the radio communication unit 11, and performs the communication management according to the control data. Unit 15 of the control plane also notifies the radio communication unit 11 about the control data to be transmitted to the mobile station 20 or the relay station 30. For example, the unit 15 of the control plane performs the process according to the radio resources control Protocol (RRC).

The control unit 16 controls the PDCCH PDCCH signaling during the random access procedure. Specifically, the control unit 16 PDCCH determines what information is included in the notification (Msg0) specialized preamble subject to transfer to the mobile station 20 or the relay station 30 by using PDCCH. For example, the control unit 16 PDCCH may insert in Msg0 identifier CI of the component carrier in which data transmission is performed.

Block 17 data plane controls the transmission and reception of user data between the mobile station 20, the relay station 30 and its own station. For example, block 17 data plane performs the processes according to the Protocol packet data convergence (PDCP) Protocol radio link control (RLC) and the Protocol control access to the transmission medium (MAC).

The block 18 control RAR controls the signaling of the MAC during the procedure, the random�access. Specifically, the block 18 control RAR determines what information is included in the response (Msg2) to the request random access to be transmitted to the mobile station 20 or the relay station 30 using the PDSCH. For example, the block 18 control RAR can insert in Msg2 identifier CI of the component carrier in which data transmission is performed.

Unit 24 of the control plane manages the transmission and reception of control data between the base station 10, the relay station 30 and its own station. Specifically, unit 24 of the control plane receives the control data extracted by the radio communication unit 21, and performs control of the communication according to the control data. Unit 24 of the control plane, in addition, notifies the radio communication unit 21 about the control data to be transmitted to the base station 10 or the relay station 30. For example, block 24 PLO�dice control performs the process according to the RRC Protocol.

Block 25 management controls the PDCCH PDCCH signaling during the random access procedure. Specifically, the block 25 of the control parses the PDCCH Msg0, subject to acceptance by PDCCH from the base station 10 or the relay station 30, and performs a process based on the information included in Msg0. When you insert CI in Msg0, for example, the block 25 of the control PDCCH performs processing of reception of the PDSCH by using the component carrier indicated by the CI. In the beginning of the reception processing can be included the stage of activation of the component carrier and the allocation of the buffer that stores the received user data.

Unit 26 of the data plane manages the transmission and reception of user data between the base station 10, the relay station 30 and its own station. For example, the unit 26 of the data plane performs the processes according to the protocols of the PDCH, RLC and MAC.

Block 27 management RAR controls the signaling of the MAC during the random access procedure. Specifically, block 27 management RAR analyzes Msg2, subject to acceptance through the PDSCH from the base station 10 or the relay station 30, and performs a process on the basis of information included in the Msg2. When you insert CI in Msg2, for example, receive processing for PDSCH is performed according to the component carrier indicated by the identifier CI.

Also in the relay station 30, the radio block�ligature and the control unit can function in the same manner, as in the base station 10 and mobile station 20. In this case, regarding the radio communication between the base station 10 and its own station, the control unit in the relay station 30 performs the same process as in the control unit 23 in the mobile station 20. As to the control of radio communication between mobile station 20 and its own station, the control unit relay station 30 further executes the same process as the one used in the control unit 14 in the base station 10.

Fig. 8 shows a block diagram illustrating the sequence of steps for the base station according to the second embodiment of the. The process shown in Fig. 8, includes the following steps:

(Step S111), the control Unit 14 sets the state of the CC #1-#5 in relation to mobile station 20. Specifically, the control unit 14 identifies the "configured but deactivated CC", "configured and activated CC", and "the set of PDCCH monitoring";

(Step S112), the control Unit 14 determines whether to implement the planning with the provision of cross-bearing. Specifically, the control unit 14 determines whether to perform data transfer in addition to the (b) component carrier, which is transmitted notification (Msg0) special preamble. The control unit 14 determines whether to implement layout�tion with the provision of cross-bearing, for example, based on the size of the data to be transmitted to the mobile station 20, and a link quality of the component carrier in which the Msg0 is transmitted. If not implement, the process advances to step S113. If implemented, the process moves to step S114;

(Step S113), the control Unit 16 sets the value of the PDCCH 0b111 in the pointer field of the carrier (CIF) included in Msg0. This string of binary digits represents that the data transmission is performed component carrier in which the Msg0 is transmitted. Instead 0b111, the control unit 16 PDCCH can specify a 3-bit CI indicating the component carrier in which the Msg0 is transmitted. The process then proceeds to step S116;

(Step S114) From among the CC #1-#5, the control unit 14 selects one or a set of component carriers in which data transmission is performed, in addition to the component carrier in which the Msg0 is transmitted. The control unit 14 selects a component carrier, for example, based on the size of the data to be transmitted to the mobile station 20, or the quality of communication to CC #1-#5;

(Step S115), the control Unit 16 PDCCH sets the 3-bit CIF indicating the component carrier selected at step S114 in the field CIF included in Msg0. The control unit 16 transmits PDCCH Msg0 for each component carrier selected at step S114;

(Step S116), the radio communication Unit 11 transmits Msg0, including CIF specified in step S113 or S115, �and the mobile station 20 by using the component carrier, included in the set of PDCCH monitoring". In case your selection in step S114 the aggregate component carriers, the radio communication unit 11 transmits the set of groups Msg0. A group of Msg0 can be transmitted through the same unit of radio transmission (e.g. podagra), or distributed on different units of radio transmission (for example, different podckaji) for the transfer;

(Step S117) In the case where the component carrier notified by Msg0, set to "configured but deactivated CC" (inactive state), the control unit 14 changes the "configured and activated CC" (active state). The radio communication unit 11 receives the preamble (Msg1) random access from the mobile station 20 by using the component carrier notified by Msg0;

(Step S118), the Block 18 control RAR generates a response to the request random access (Msg2), not including the CIF. The radio communication unit 11 transmits the Msg2 to the mobile station 20 by using the component carrier in which is taken Msg1. Then, data transmission is performed component carrier, which is transmitted and received Msg1 and Msg2.

Fig. 9 shows a block diagram illustrating the sequence of operations of the mobile station according to the second embodiment of the. The process shown in Fig. 9, involves the following steps:

(Step S121), the control Unit 23 sets the state of the CC #1-#5. Specifically, the control unit 23 identifies the "configured but deactivated CC", "configured and activated CC" and "the set of PDCCH monitoring". The radio communication unit 21 monitors the PDCCH through the component carrier included in the set of PDCCH monitoring";

(Step S122), the radio communication Unit 21 receives Msg0 from the base station 10 by using the component carrier included in the set of PDCCH monitoring". Block 25 PDCCH control extracts the CIF included in Msg0. If the aggregate groups Msg0, block 25 PDCCH control extracts in each CIF Msg0;

(Step S123) Unit 25 PDCCH control identifies the component carrier indicated by the CIF, extracted in step S122, and performs processing of receiving PDSCH using the above component carrier. In the case where the component carrier indicated by the CIF, is set as the "configured but deactivated CC", block 25 PDCCH control changes the "configured and activated CC". Unit 22 installation providing cross-carrier sets the frequency band to perform the signal processing;

(Step S124), the radio communication Unit 21 transmits Msg1, using the signal sequence specified by Msg0, to the base station 10 according to PRACH component carrier, �specified by CIF. If the aggregate groups Msg0 and identification of the aggregate component carriers in step S123, the radio communication unit 21 transmits Msg1 for each identified component carrier. The radio communication unit 21 may transmit the set of groups Msg1 with the same temporal distribution, or other temporary distribution;

(Step S125), the radio communication Unit 21 receives Msg2 from the base station 10 by using the component carrier in which the Msg1 is transmitted. Block 27 management RAR performs processing on the basis of information included in the Msg2. The radio communication unit 21 performs data transmission by using the component carrier, which is transmitted and received Msg1 and Msg2.

Fig. 10 illustrates a first example of random access according to the second embodiment of the. Here supposed that the mobile station 20 sets the CC #1 and #2 as the "configured and activated CC and CC #3 - #5 - as the "configured but deactivated CC". Relies on to state that "the set of PDCCH monitoring" includes only CC#1.

(Step S131), the base station 10 transmits Msg0, including the CIF=0b001, to the mobile station 20 by using the CC #1 set as "the set of PDCCH monitoring".

(Step S132) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#2, indicated by the CIF=0b001. Since CC#2 set�Jena as the "configured and activated CC", mobile station 20 is not required to change the state of the CC #2.

(Step S133), the base station 10 transmits Msg2 to the mobile station 20 by using the CC#2, which was adopted by Msg1. For example, the mobile station 20 then transmits data to the base station 10 by using the CC#2.

Transmission characteristics of the signals are different in each component carrier in each frequency band). Consequently, when Msg1 and Msg2 are transmitted and received component carrier, in which data transmission is performed, effectively achieving stabilization of data transmission. In addition, for ease of explanation Fig. 10, only CC#1 is set as "the set of PDCCH monitoring", and, in addition, any CC can also be set as "the set of PDCCH monitoring". In this case, the Msg0 is transmitted through the CC set as "the set of PDCCH monitoring".

Fig. 11 illustrates a second example of random access according to the second embodiment of the. Status for CC #1-#5 during the start of the random access procedure are identical with those of Fig. 10.

(Step S141), the base station 10 transmits Msg0 including CIF=0b010, to the mobile station 20 by using the CC #1 set as "the set of PDCCH monitoring". Since the CC #3 indicated by the CIF=0b010, set to "configured but deactivated CC", activate it and edit�ly in the "configured and activated CC".

(Step S142) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#3 indicated by the CIF=0b010. At this time, in the same way as in the base station 10, mobile station 20 activates CC#3 and changes it into the "configured and activated CC".

(Step S143), the base station 10 transmits Msg2 to the mobile station 20 by using the CC#3, which was adopted by Msg1. For example, the mobile station 20 then transmits data to the base station 10 by using the CC#3.

When the procedure is executed to transmit and receive Msg0 and Msg1, base station 10 and mobile station 20 changes the state of the CC #3.

Specifically, Msg0 and Msg1 are also signaling to change the state of the CC#3. Accordingly, the base station 10 and mobile station 20 does not need to separately perform the alarm to change the state of the CC#3.

Fig. 12 illustrates a third example of random access according to the second embodiment of the. The state of the CC #1-#5 during the start of the random access procedure are identical with those of Fig. 10.

(Step S151), the base station 10 transmits Msg0, including the CIF=0b001, to the mobile station 20 by using the CC#1 set as "the set of PDCCH monitoring".

(Step S152), the base station 10 transmits Msg0, including the CIF=0b010, to the mobile station 20 by using the CC#1. Since CC#3, of the decree�Naya CIF=0b010, set to "configured but deactivated", the base station 10 activates CC#3 and changes it into the "configured and activated CC". Base station 10 may optionally pass two sets Msg0 with the same temporal distribution.

(Step S153) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#2, indicated by the CIF=0b001.

(Step S154) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#3 indicated by the CIF=0b010. At this time, in the same way as in the base station 10, mobile station 20 activates CC#3 and changes it into the "configured and activated CC". Mobile station 20 may then transmit two sets Msg1 with the same temporal distribution.

(Step S155) Using CC#2, the base station 10 receives and transmits Msg1 Msg2 to the mobile station 20. Using CC#2, for example, the mobile station 20 then transmits data to the base station 10.

(Step S156) Using CC#3, the base station 10 receives and transmits Msg1 Msg2 to the mobile station 20. Using CC#3, for example, the mobile station 20 then transmits data to the base station 10.

The signal sequence specified by Msg0 transmitted in step S151, and the signal sequence specified by Msg0 transmitted in step S152, may be the same or different �t other. Specifically, in relation to Msg1 transmitted in step S153 and Msg1 transmitted in step S154, the mobile station 20 may use the same signal sequence or different signal sequence.

In the above example of planning with the provision of cross-bearing is considered that the base station 10 identifies the status for CC #1-#5 mobile station 20. In the case if the base station 10 or the mobile station 20 believe that some of the component carriers among the CC #1-#5 are unused, the base station 10 makes such a component carrier and selects the component carrier in which data transmission is performed. The above planning with the provision of cross-bearing is implemented, for example, at the time when the mobile station 20 performs random access to the base station 10 from the state of the connected mode or non-working mode.

Fig. 13 illustrates a first example of the format of the Msg0. Msg0 is a control message to be transmitted over PDCCH. As the field(s), Msg0 includes a flag (Flag), local/distributed (Local/Dist), the purpose of the resource block (Resource Block Assignment), the index of the preamble (Preamble Index), the index of the mask PRACH (PRACH Mask Index), index carrier (Carrier Indicator) and cyclic redundancy code (CRC). The length in bits of the field Resource Block Assignment is�tsya different depending on bandwidth DL component carrier. Fig. 13 illustrates frequency band using a number of resource blocks (RB). Here, 100 RB correspond to the width of the strip 20 MHz.

Field except Carrier Indicator, as described, for example, in the document "Evolved Universal Terrestrial Radio Access (E-UTRA); Multiplexing and channel coding" (Enhanced universal terrestrial radio access (E-UTRA); Multiplexing and channel coding) (3GPP, technical description TS 36.212 V9.0.0, 2009-12). In the second variant of implementation Flag is set to 1, Local/Dist is set to 0 and all sets of Resource Block Assignment set to 1. If for lengthening Msg0 bit is inserted a fixed value, the accuracy of error detection is increased. Field Preamble Index indicates information for specifying the signal sequence used for Msg1. Field PRACH Mask Index indicates information used to effect a transfer of Msg1. The CRC field specifies the parity used for error detection in Msg0.

As described above, the field of the Carrier Indicator indicates a 3-bit string of bits to specify the component carrier in which data transmission is performed. In the example of Fig. 13 field Carrier Indicator is inserted between the PRACH Mask Index and CRC field. In the above literature "Evolved Universal Terrestrial Radio Access (E-UTRA); and Multiplexing and channel coding", and described the format in which there is a eld complement spaces (Padding) between the PRACH Mask Index and CRC field.

Fig. 14 illustrates a second example f�of rmat Msg0. In the example format of Fig. 14 the most significant 3 bits of the string of bits allocated to the field Resource Block Assignment in the example format of Fig. 13, are highlighted field Carrier Indicator. Specifically, field Carrier Indicator is inserted between the Local/Dist and field Resource Block Assignment. Field Padding is provided between the PRACH Mask Index and CRC field. All groups Padding set to 1.

Fig. 15 illustrates a third example of the format of the Msg0. In the example format of Fig. 15 the least significant 3 bits of the string of bits allocated to the field Resource Block Assignment in the example format of Fig. 13, are highlighted field Carrier Indicator. Specifically, field Carrier Indicator is inserted between the field Resource Block Assignment and a Preamble index.

In addition, for sample formats of Fig. 14 and 15, also examines the way in which intermediate the least significant 3 bits of binary string of marks allocated to the assignment of the resource block in the example format of Fig. 13, selects a field indicator of the carrier.

In particular, in the example format, the size of the data Msg0 is different depending on bandwidth DL component carrier. Consequently, a group of Msg0, with different sizes of data can be transmitted using CC#1. We can assume, for example, that bandwidth DL for CC#2 is 20 MHz, and bandwidth DL for CC#3 is 10 MHz. In this case Msg0 corresponding to CC#2, and Msg0 corresponding to CC#3, have various dimensions l�granted.

On the other hand, the mobile station 20 blind decodes PDCCH and extracts Msg0. Accordingly, to reduce the overhead of blind decoding, the mobile station 20 preferably adjusts the size so that the size of Msg0 could be permanent, even if the frequency band DL is different depending on the component carrier. In addition, to facilitate the extraction of CIF, the mobile station 20 preferably makes a permanent position in CIF full Msg0.

Fig. 16 illustrates a first example of adjusting the size Msg0. An example of adjusting the size of Fig. 16 corresponds to an example of the format illustrated in Fig. 13. In this example, adjust the size of the PADDING field, having a length in accordance with the bandwidth of DL, is inserted between the field Resource block Assignment and a Preamble Index. Due to the process size Msg0 becomes constant relative to the bandwidth DL. Since the position of the CIF is permanent, after decoding Msg0, CIF is easily removed to identify the component carrier to be used. In addition, since the position of the Preamble field Index and field PRACH Mask Index are constant, Msg1 can be easily formed by using the link on the above fields.

Fig. 17 illustrates a second example of adjusting the size of the Msg0. An example of adjusting the size of Fig. 17 corresponds to an example of the format shown in Fig. 14. So �e, as in the example of adjusting the size of Fig. 16, field PADDING length in accordance with the bandwidth of DL, is inserted between the field Resource block Assignment and a Preamble Index. Throughout the process the size Msg0 becomes constant, while the position of the CIF becomes constant regardless of bandwidth DL. The position of the Preamble field Index and field PRACH Mask Index then become constant.

Fig. 18 illustrates a third example of adjusting the size of the Msg0. An example of adjusting the size of Fig. 18 corresponds to an example of the format illustrated in Fig. 15. In this example, adjust the size of the PADDING field with a length in accordance with the bandwidth of DL, is inserted between the Local/Dist and field Resource Block Assignment. Throughout the process the size Msg0 becomes constant, while the position of the CIF becomes constant regardless of bandwidth DL. The position of the Preamble field Index and field PRACH Mask Index then become constant.

According to this mobile communication system according to the second embodiment of the implementation, by passing Msg0 to the mobile station 20, the base station 10 provides the mobile station 20 permission to use component carriers, in addition to the component carrier in which the Msg0 is transmitted. In other words, the base station 10 implements the planning with the provision of cross-bearing by using Msg0. Accordingly, basic PT�ncia 10 and mobile station 20 does not need to separately perform the procedure to allow use of the component carrier.

The base station 10 and mobile station 20 then change the state of a component carrier in an inactive state into an active, along with the transmission and reception Msg0 and Msg1. Accordingly, the base station 10 and mobile station 20 is not required to perform the procedure to change the state of the component carrier. As can be seen from the above description, the base station 10 and mobile station 20 effectively control the use of a range of component carriers.

The THIRD VARIANT of IMPLEMENTATION

Then will be described a third option implementation. The third variant of implementation will be described with focusing on the difference from the above-described second embodiment, and the same questions will not be repeated. In the second variant of implementation planning with the provision of cross-bearing is realized through Msg0, and, on the other hand, planning the provision of cross-bearing is realized through Msg2 in the third variant of implementation.

The mobile communication system in accordance with a third embodiment of the implementation is realized by the same system configuration as the mobile communication system according to the second variant implementation, shown in Fig. 2. Base station and mobile station according to a third embodiment of the are implemented according to the same configuration�the third blocks, as for the base station 10 and mobile station 20 according to the second variant implementation, shown in Fig. 6 and 7. The third variant of implementation will be described below using reference positions used in Fig. 2, 6 and 7.

(Step S211), the control Unit 14 sets the state of the CC #1-#5, the mobile station 20. Specifically, the control unit 14 identifies the "configured but deactivated CC", "configured and activated CC" and "the set of PDCCH monitoring";

(Step S212), the control Unit 16 generates a PDCCH notification (Msg0) special preamble, not including the CIF. The radio communication unit 11 transmits Msg0 to the mobile station 20 by using the component carrier included in the set of PDCCH monitoring;

(Step S213), the radio communication Unit 11 receives the preamble (Msg1) random access from the mobile station 20 by using the component carrier in which the Msg0 is transmitted;

(Step S214), the control Unit 14 determines whether to implement the planning with the provision of cross-bearing. Specifically, the control unit 14 determines whether to perform data transfer in addition to the component are�her in which is transmitted the random access response (Msg2). If not implement, the process advances to step S215. If you implement, then the process moves to step S216;

(Step S215), the Block 18 control sets RAR 0b111 in the CIF included in the Msg2. This string of binary digits indicates that the data transmission is performed component carrier in which the Msg2 is transmitted. The process then proceeds to step S218;

(Step S216) From among carriers CC #1-#5, the control unit 14 selects one or a set of component carriers in which data transmission is performed, in addition to the component carrier, which is transmitted Msg2;

(Step S217), the Block 18 control sets RAR a 3-bit CIF indicating the component carrier selected at step S216. It is noted that Msg2 is transmitted for each component carrier selected at step S216;

(Step S218), the radio communication Unit 11 transmits Msg2, including CIF, installed in step S215 or S217, the mobile station 20 by using the component carrier included in the set of PDCCH monitoring". In case your selection in step S216 the aggregate component carriers, the radio communication unit 11 transmits a group of Msg2. In the case where the state of the component carrier notified by Msg2, set to "configured but deactivated CC" (inactive state), the control unit 14 changes in konfigurera�nnaya and activated CC" (active state). The radio communication unit 11 then performs data transmission by using the component carrier notified by Msg2.

Fig. 20 shows a block diagram illustrating the sequence of operations of the mobile station according to a third embodiment of the. The process that is illustrated in Fig. 20, includes the following steps:

(Step S221), the control Unit 23 sets the state of the CC #1-#5. Specifically, the control unit 23 identifies the "configured but deactivated CC", "configured and activated CC" and "the set of PDCCH monitoring". The radio communication unit 21 performs PDCCH monitoring component carrier included in the set of PDCCH monitoring";

(Step S222), the radio communication Unit 21 receives Msg0, not including the CIF from the base station 10 by using the component carrier included in the set of PDCCH monitoring";

(Step S223), the radio communication Unit 21, using the signal sequence specified by Msg0, sends Msg1 to the base station 10 using the PRACH in the component carrier in which the Msg0 is transmitted;

(Step S224), the radio communication Unit 21 receives Msg2 from the base station 10 by using the component carrier in which the Msg1 is transmitted. Block 27 management RAR extracts the CIF included in the Msg2. In case of the aggregate group Msg2, block 27 management RAR extracts the CIF for each Msg2;

(Step S25), the control Unit a 27 RAR identifies one component carrier or a set of component carriers, specified by CIF extracted in step S224, and performs relatively PDSCH reception processing using the component carriers. In the case where the component carrier indicated by the CIF, is set as the "configured but deactivated CC", block 27 management RAR changes its state to "configured and activated CC". Unit 22 installation providing cross-carrier sets the frequency band to perform the signal processing;

(Step S226), the radio communication Unit 21 performs data transmission by using the component carrier identified in step S225.

Fig. 21 illustrates a first example of random access according to a third embodiment of the. Here supposed that the mobile station 20 sets the state for the CC #1 and #2 as the "configured and activated CC" for CC #3-#5 - as the "configured but deactivated CC". Further, it is believed that the set of PDCCH monitoring" includes only CC #1.

(Step S231), the base station 10 transmits Msg0 to the mobile station 20 by using the CC #1 set as "the set of PDCCH monitoring".

(Step S232) the Mobile station 20 sends Msg1 to the base station 10 by using the CC #1, which was adopted Msg0.

(Step S233), the base station 10 transmits Msg2, including the CIF=0b001, to the mobile station 20 by and�use CC#1, in whom Msg1. In Msg2 includes adjusting the temporal distribution relative to the bandwidth of the UL CC#2.

(Step S234) Using CC#2, indicated by the CIF=0b001, for example, mobile station 20 transmits data to the base station 10. It is noted that since the CC#2 is set as the "configured and activated CC", the mobile station 20 is not required to change the state of the CC #2.

Fig. 22 illustrates a second example of random access according to a third embodiment of the. The state of the CC #1-#5 during the start of the random access procedure are identical with those of Fig. 21.

(Step S241), the base station 10 transmits Msg0 to the mobile station 20 by using the CC#1 set as "the set of PDCCH monitoring".

(Step S242) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#1, which was adopted Msg0.

(Step S243), the base station 10 transmits Msg2, including the CIF=0b010, to the mobile station 20 by using the CC#l, in whom the Msg1. Since the CC#3 indicated by the CIF=0b010, set to "configured but deactivated CC", the base station 10 activates CC#3 and changes its state to "configured and activated CC". It is noted that in the Msg2 includes adjusting the temporal distribution relative to the bandwidth of U in CC#3.

(Step S244) Using CC#3 indicated by the CIF=0b010, for example, mobile station 20 transmits data to the base station 10. At this time, in the same way as in the base station 10, mobile station 20 activates CC#3 and changes the state to "configured but deactivated CC" in the "configured and activated CC".

Fig. 23 illustrates a third example of random access according to a third embodiment of the. The state of the CC #1-#5 during the start of the random access procedure are identical with those of Fig. 21.

(Step S251), the base station 10 transmits Msg0 to the mobile station 20 by using the CC#1 set as "the set of PDCCH monitoring".

(Step S252) the Mobile station 20 sends Msg1 to the base station 10 by using the CC#1, which was adopted Msg0.

(Step S253), the base station 10 transmits Msg2, including the CIF=0b001, to the mobile station 20 by using the CC#1, which was adopted by Msg1. It is noted that in the Msg2 includes information timing can be adjusted relative to the bandwidth of the UL CC#2.

(Step S254), the base station 10 transmits Msg2, including the CIF=0b010, to the mobile station 20 by using the CC#1, which was adopted by Msg1. Since the CC#3 indicated by the CIF=0b010, set to "configured but deactivated CC", the base station 10 activates CC#3 and changes�splash zones, its status in the "configured and activated CC". It is noted that in the Msg2 includes adjusting the temporal distribution relative to the bandwidth of the UL CC#3.

(Step S255) Using CC#2, indicated by the CIF=0b001, for example, mobile station 20 transmits data to the base station 10.

(Step S256) Using CC#3 indicated by the CIF=0b010, for example, mobile station 20 transmits data to the base station 10. At this time, in the same way as in the base station 10, mobile station 20 activates CC#3 and changes the state to "configured but deactivated CC" in the "configured and activated CC".

Fig. 24 illustrates a first example of the format of Msg2. In the example format of Fig. 24 message Msg2 includes the pointer carrier (Carrier Indicator) in 3 bits, the command timing (Timing Advance Command) in 6 bits, the provision of UL in 20 bits, and the temporary ID cell in the radio network (Temporary C-RNTI) to 16 bits.

As described above, the carrier indicator is a value for distinguishing the component carrier in which data transmission is performed. The Timing Advance command is a value indicating the amount of adjustment time distribution at the time of authorization of mobile station 20 to clarify the temporal distribution of transmission on UL. "Providing UL" (UL grant is information describing the UL radio resource allocated to the mobile station 20. Temporary C-RNTI, I�is ID, dynamically allocated mobile station 20 through the base station 10. In addition, the Timing Advance command indicates the amount of adjustment time distribution related to the component carrier indicated by the Carrier Indicator. Accordingly, the mobile station 20 regulates the temporal distribution of UL transmission after the random access procedure by using a Timing Advance command.

In this case, the Timing Advance command is described, for example, in the document "Evolved Universal Terrestrial Radio Access (E-UTRA); Physical layer procedures" (Enhanced universal terrestrial radio access (E-UTRA); physical layer") (technical specifications 3GPP TS 36.213 V9.0.1, 2009-12).

In the above literature, two types of absolute value in the shift of the temporal distribution and relative values, using as a reference current specified temporal distribution, defined as the Timing Advance command. The absolute value is used in the case where Timing Advance command is reported for the first time, or is expired period of validity of the previously reported Timing Advance command. Relative value is used in the case where the period of validity of the previously reported Timing Advance command is not expired. Absolute value is represented by 11 bits, and the relative value represented by 6 bits. In the example format of Fig. 24 supposed that relative value is used.

In the above example the format of the redundant most significant bit is set to one. The most significant bit of R in Msg2, not including the CIF, is set to zero. Throughout the process the mobile station 20 is easy to determine whether the Msg2 in CIF.

(Step S312), the radio communication Unit 11 receives the preamble (Msg1) random access from the mobile station 20 by using the component carrier included in the set of PDCCH monitoring". The signal sequence used in Msg1 is selected by the mobile station 20 randomly;

(Step S313), the control Unit 14 determines whether to implement the planning with the provision of cross-bearing. If not, then the process moves to step S314. If so, the process moves to step S315;

(Step S314), the Block 18 control sets RAR 0b111 as a CIF included in the Msg2. The process then proceeds to step S317;

(Step S315) From among the CC #1-#5, the control unit 14 selects one or a set of component carriers in which data transmission is performed, in addition to the component carrier, which is transmitted Msg2;

(Step S316), the Block 18 control sets RAR a 3-bit CIF indicating the component carrier selected at step S315. In addition, Msg2 is transmitted for each component carrier selected at step S315;

(Step S317), the radio communication Unit 11 transmits Msg2, including CIF, installed in step S314 or S316, the mobile station 20 by using the component carrier in which is taken Msg1. In case your selection in step S315, savecopyas�and component carriers, the radio communication unit 11 transmits a group of Msg2;

(Step S318), the radio communication Unit 11 receives Msg3 from the mobile station 20 by using the component carrier notified by Msg2. At this time, in the case where the component carrier notified by Msg2, set to "configured but deactivated CC" (inactive state), the control unit 14 changes the "configured and activated CC" (active);

(Step S319), the radio communication Unit 11 sends Msg4 to the mobile station 20 by using the component carrier in which is taken Msg3. The radio communication unit 11 then performs data transmission by using the component carrier, which is transmitted and received Msg3 and Msg4.

(Step S321), the control Unit 23 sets the state of the CC #1-#5. Specifically, the control unit 23 identifies state "configured but deactivated CC", "configured and activated CC" and "the set of PDCCH monitoring". The radio communication unit 21 performs PDCCH monitoring component carrier included in the set of PDCCH monitoring";

(Step S322), the radio communication Unit 21 transmits Msg1, IP�alzua randomly selected signal sequence, to the base station 10 by using a PRACH component carrier included in the set of PDCCH monitoring";

(Step S323), the radio communication Unit 21 receives Msg2 from the base station 10 by using the component carrier in which the Msg1 is transmitted. Block 27 management RAR extracts the CIF included in the Msg2. In case of the aggregate group Msg2, block 27 management RAR extracts the CIF for each Msg2;

(Step S324) Block 27 management RAR identifies one or a set of component carrier indicated by the CIF, extracted in step S323. In the case where the component carrier indicated by the CIF, is set as the "configured but deactivated CC", block 27 management RAR changes its state into the "configured and activated CC". Unit 22 installation providing cross-carrier sets the frequency band to perform the signal processing;

(Step S325), the radio communication Unit 21 transmits an Msg3 to the base station 10 by using the component carrier indicated by the CIF. In case of the aggregate group Msg2 and identification of the aggregate component carriers in step S324, the radio communication unit 21 transmits an Msg3 to the base station 10 for each of the identified component carrier. A group of Msg3 can be transmitted with the same temporal distribution or other temporary distribution;

(�tap S326), the radio communication Unit 21 receives Msg4 from the base station 10 by using the component carrier, in which Msg3 is transmitted. The radio communication unit 21 then performs data transmission by using the component carrier, which is transmitted and received Msg3 and Msg4.

(Step S334), the base station 10 sends Msg4 to the mobile station 20 by using the CC#2, which was adopted Msg3. Using CC#2, for example, the mobile station 20 then transmits data to the base station 10. It is noted that if there is a conflict of random access, the mobile station 20 then transmits Msg1 on base with�Anzio 10.

Fig. 30 illustrates a second example of random access according to the fourth variant implementation. Status for CC #1-#5 during the start of the random access procedure are identical with those of Fig. 29.

(Step S341) the Mobile station 20 transmits Msg1, using randomly selected signal sequence to the base station 10 by using the CC#1 set as "the set of PDCCH monitoring".

(Step S342), the base station 10 transmits Msg2, including the CIF=0b010, to the mobile station 20 by using the CC#1, which was adopted by Msg1. Since the CC#3 indicated by the CIF=0b010, set to "configured but deactivated CC", the base station 10 activates CC#3 and changes its state to "configured and activated CC".

(Step S343) the Mobile station 20 transmits an Msg3 to the base station 10 by using the CC#3 indicated by the CIF=0b010. In the same way as in the base station 10, mobile station 20 activates CC#3 and changes the state to "configured but deactivated CC" in the "configured and activated CC".

(Step S344), the base station 10 sends Msg4 to the mobile station 20 by using the CC#3, which was adopted Msg3. Using CC#3, for example, the mobile station 20 then transmits data to the base station 10.

Fig. 31 illustrates a third �reamer random access according to the fourth variant implementation. The state of the CC #1-#5 during the start of the random access procedure are identical with those of Fig. 29.

(Step S351) the Mobile station 20 transmits Msg1, using randomly selected signal sequence to the base station 10 by using the CC#1 set as "the set of PDCCH monitoring".

(Step S353), the base station 10 transmits Msg2, including the CIF=0b010, to the mobile station 20 by using the CC#1, which was adopted by Msg1. Since the CC#3 indicated by the CIF=0b010, set to "configured but deactivated CC", the base station 10 activates CC#3 and changes its state into the "configured and activated CC".

(Step S354) the Mobile station 20 transmits an Msg3 to the base station 10 by using the CC#2, indicated by the CIF=0b001.

(Step S355) the Mobile station 20 transmits an Msg3 to the base station 10 by using the CC#3 indicated by the CIF=0b010. At this time, in the same way as in the base station 10, mobile station 20 activates CC#3 and changes the state to "configured but deactivated CC" in the "configured and activated CC".

(Step S356), the base station 10 sends Msg4 to the mobile station 20 through the use�ing CC#2, in whom Msg3.

(Step S357), the base station 10 sends Msg4 to the mobile station 20 by using the CC#3, which was adopted Msg3.

As the format Msg2 according to the fourth embodiment of the used example of the format described in the third variant of implementation. In random access, contention, because there is a possibility that the base station 10 identifies the mobile station 20 during the transmission Msg2, preferably formats are used as in Fig. 25 and 26, which is passed to the Timing Advance command for absolute value. In the fourth embodiment of the, for this reason, it is preferable that the mobile station 20 may use all component carriers or a preselected number of them.

In addition, in the case of random access contention, it is also believed that planning with the provision of cross-bearing is being implemented to balance the load with the result that the set of mobile stations do not use intensively specific component carrier, the dispensing component carriers, a random access procedure to reduce interference between cells, and dispensing component carriers in which the Msg3 is transmitted, to reduce the likelihood of conflict.

According to the above system mobile�Noah regard to the fourth embodiment of the, the base station 10 implements the planning with the provision of cross-bearing with the use of Msg2 in the same manner as in the third variant of implementation. Accordingly, the procedure permits the use of a component carrier is not required to perform separately. Along with the transmission and reception of Msg2 and Msg3, the base station 10 and mobile station 20 then modify the component carrier is in an inactive state in that in the active state. Consequently, the procedure of changing the state of the component carrier is not required to perform separately. As you can see on the above discussion, the base station 10 and mobile station 20 effectively control the use of a range of component carriers in the same manner as in the second and third variants of the implementation.

The foregoing is considered only as illustrative on the principles of the present invention. Furthermore, since numerous modifications and changes will easily come to mind skilled in the art, it is undesirable to limit the invention to the strict performance and applications shown and described, and accordingly, all suitable modifications and equivalents should be considered within the scope of the invention in the appended claims and its equivalents.
