Mobile station apparatus and base station apparatus

A method for a mobile station apparatus, comprising:

• generating a radio resource control message including mobile station apparatus capability information;
• and
• transmitting the radio resource control message to a base station apparatus, wherein
• the mobile station apparatus capability information includes a plurality of parameters including a first parameter,
• the first parameter indicates one or more configuration informations,
• each of the one or more configuration informations indicates a combination of uplink information and downlink information,
• the uplink information includes first information indicating a first quantity of component carriers included in a first band of a plurality of bands, and
• the downlink information includes second information indicating a second quantity of component carriers included in a second band of the plurality of bands.

A base station apparatus comprising:

• reception circuitry configured to receive from a mobile station apparatus, a radio resource control message including mobile station apparatus capability information;
• and
• control circuitry configured to allocate to the mobile station apparatus, one or more component carriers to be used for communication, based on the mobile station apparatus capability information, wherein
• the mobile station apparatus capability information includes a plurality of parameters including a first parameter,
• the first parameter indicates one or more configuration informations,
• each of the one or more configuration informations indicates a combination of uplink information and downlink information,
• the uplink information includes first information indicating a first quantity of component carriers included in a first band of a plurality of bands, and
• the downlink information includes second information indicating a second quantity of component carriers included in a second band of the plurality of bands.
