Abstract

A mobile station apparatus transmits capability information including at least indicator selected from a plurality of indicators that each define 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 quantity of component carriers included in the one or more component carriers. A base station apparatus includes a controller that allocates to a mobile station apparatus one or a plurality of component carriers to be used for communication based on a radio resource control (RRC) message received from the mobile station apparatus. The RRC message includes mobile station apparatus capability information including at least one indicator selected from the plurality of indicators.

Claims

1. A mobile station apparatus comprising:

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

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

the mobile station apparatus capability information includes;

a frequency band number, and

a first indicator and a second indicator which are selected from a plurality of indicators,

each of the plurality of indicators indicates a combination of first information and second information,

the first information is associated with an aggregated frequency bandwidth of one or more component carriers,

the second information is associated with the quantity of component carriers included in the one or more component carriers,

the first indicator is used for uplink,

the second indicator is used for downlink, and

the first indicator and the second indicator are associated with the frequency band number.

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

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

the mobile station apparatus capability information includes;
