Disclosed is a terminal device in which increase in the overhead of an uplink control channel can be suppressed even when SCTD is applied to the transmission of response signals and SRs. Either a response signal or SR is allocated to mutually different encoding resources, and a terminal (200) transmits from each of a plurality of antennas. A control section (208) transmits a response signal or SR using an SR resource or ACK/NACK resource, which are mutually different encoding resources, and a shared resource. The control section (208) uses the encoding resource, which is either the SR resource to which a response signal is allocated when a response signal and SR are generated concurrently, and to which an SR is allocated when only an SR is generated, or the ACK/NACK resource to which a response signal is allocated when only a response signal is generated. The control section (208) also uses the shared resource to which a response signal is allocated when a response signal and SR are generated concurrently and when only a response signal is generated, and to which an SR is allocated when only an SR is generated. |
