Abstract
To efficiently control channel quality indicators CQIs in response to a plurality of downlink component frequency bands in a wireless communication system using a plurality of component frequency bands, and enable a mobile station apparatus to suitably transmit signals including the channel quality indicators CQIs, the mobile station apparatus is provided with an uplink control data generation part 407 that generates a channel quality indicator in response to each of the downlink component frequency bands, an uplink control channel selection part 409 that selects a particular radio resource when a plurality of radio resources, which are beforehand allocated from the base station apparatus to transmit the channel quality indicator for each of the downlink component frequency bands, occurs in the same time frame, and a transmission processing part 405 that arranges the channel quality indicator generated in the uplink control data generation part 407 in the radio resource selected in the uplink control channel selection part 409 to transmit to the base station apparatus.
