<p>A mobile station apparatus efficiently codes and transmits ACK/NACKs for a plurality of PDSCHs. The mobile station transmits a plurality of ACK/NACKs for transport blocks transmitted by a base station apparatus in a plurality of component carriers to the base station. First and second ACK/NACKs are individually coded, repetition processing is performed on coded bits of the first ACK/NACKs until the number of coded bits of the first ACK/NACKs reaches a first value, the repetition processing is performed on the coded bits of the second ACK/NACKs until the number of coded bits reaches a second value, the coded bits of the first ACK/NACKs and the coded bits of the second ACK/NACKs are concatenated, and the first ACK/NACKs and the second ACK/NACKs are transmitted to the base station apparatus using one physical uplink channel.</p> |
