Abstract

An ASN encoder of a mobile station apparatus generates transmission and reception capability information including information relating to one or a plurality of component carriers to be used for communication with a base station apparatus. A transmission and reception apparatus transmits the transmission and reception capability information to the base station apparatus. A controller controls the communication with the base station apparatus, using the one or the plurality of component carriers assigned by the base station apparatus based on the transmission and reception capability information.

Claims

1. A mobile station apparatus comprising:

a radio resource control message generator configured to include mobile station apparatus capability information in a radio resource control message; and

a transmitter configured to transmit the radio resource control message including the mobile station apparatus capability information to a base station apparatus, wherein

the mobile station apparatus capability information includes a first indicator which is selected from a plurality of indicators and a second indicator which is selected from the plurality of indicators,

each of the plurality of indicators defines at least a combination of first information associated with an aggregated frequency bandwidth of one or more component carriers and second information associated with the number of component carriers included in the aggregated frequency bandwidth of the one or more component carriers,

the first indicator is used for uplink, and

the second indicator is used for downlink.

2. The mobile station apparatus according to claim 1, wherein the indicators respectively associated with uplink frequency bands and downlink frequency bands have a hierarchical structure.

3. The mobile station apparatus according to claim 1, wherein the mobile station apparatus capability information further includes multiple-input multiple-output (MIMO) capability information.

6. The mobile station apparatus according to claim 3, wherein the MIMO capability information includes information indicating the number of layers.

7. The mobile station apparatus according to claim 3, wherein the MIMO capability information includes information indicating the number of MIMO streams.

8. The mobile station apparatus according to claim 3, wherein the MIMO capability information includes information indicating a plurality of numbers, each number indicating the number of layers.

9. The mobile station apparatus according to claim 8, wherein the plurality of numbers are 2 and 4.

10. The mobile station apparatus according to claim 8, wherein the plurality of numbers are 2, 4, and 8.

11. The mobile station apparatus according to claim 3, wherein the MIMO capability information includes a number indicating the number of data streams.

12. The mobile station apparatus according to claim 3, wherein the MIMO capability information includes a number indicating the number of antennas.

4. A communication control method for a mobile station apparatus, the communication control method comprising:

including mobile station apparatus capability information in a radio resource control message; and

transmitting the radio resource control message including the mobile station apparatus capability information to a base station apparatus, wherein
