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.

主权项

1. A wireless communication system comprising:
a base station apparatus; and a mobile station apparatus configured to receive signals transmitted from the base station apparatus using a plurality of downlink component frequency bands each having a beforehand determined frequency bandwidth, and the base station apparatus is configured to receive a signal transmitted from the mobile station apparatus using one or more uplink component frequency bands each having a beforehand determined frequency bandwidth, wherein the base station apparatus comprises:
a reception processing part configured to receive a signal including a channel quality indicator indicative of channel quality of a downlink component frequency band transmitted from the mobile station apparatus, and the mobile station apparatus comprises:
an uplink control data generation part configured to generate a channel quality indicator in response to each of the downlink component frequency bands,an uplink control channel selection part configured to select a particular periodic physical uplink control channel (PUCCH) in case that a plurality of periodic PUCCHs, which are beforehand allocated from the base station apparatus to transmit the channel quality indicator for each of the downlink component frequency bands, occur in the same UL subframe,wherein, an UL subframe where each periodic PUCCH of the plurality of periodic PUCCHs occurs is determined based on the cycle of the UL subframe and the position of the UL subframe where an occurrence of the periodic PUCCH has started, anda transmission processing part configured to arrange the channel quality indicator generated in the uplink control data generation part in the periodic PUCCH selected in the uplink control channel selection part to transmit to the base station apparatus.
