Abstract
To perform control of PUSCH retransmission efficiently in a wireless communication system where a mobile station apparatus and a base station apparatus communicate with each other using a plurality of downlink component carriers. In a mobile station apparatus which communicates with a base station apparatus using a plurality of downlink component carriers and a plurality of uplink component carriers in case that the downlink component carrier corresponding to the uplink component carrier is set not to be used for downlink communication the mobile station apparatus flushes HARQ buffers of the uplink component carrier associated with the downlink component carrier set not to be used for downlink communication.
