Abstract:
1. A terminal apparatus that communicates with a base station, using some or all of a plurality of configured downlink component carriers, the apparatus comprising: a receiving section that receives downlink allocation control information portions transmitted through downlink control channels of the plurality of downlink component carriers and downlink data transmitted through a downlink data channel indicated by the downlink allocation control information portions; a generating section that generates a response signal based on success or failure in receiving the downlink data, the response signal including a first response signal corresponding to a first downlink component carrier among the plurality of component carriers and a second response signal corresponding to a second downlink component carrier among the plurality of component carriers; a coding section that separately encodes the first response signal and the second response signal; and a mapping section that maps the first response signal and the second response signal to different regions in an uplink data channel region, respectively, while the first response signal and the second response signal are time-multiplexed with an uplink data, wherein the mapping section maps the first response signal to the same region independently of a reception situation of the downlink allocation control information portions in the plurality of downlink component carriers.
