A terminal capable of ensuring that when a UL-DL configuration is switched over, recognition of a UL HARQ process continued in the UL-DL configuration before and after the switc hover is matched between a base station and the terminal. A terminal (200) can be switched to either one of a plurality of configuration patterns including a downlink subframe used in downlink communication and an uplink subframe used in uplink communication. Mapping between an uplink subframe and a retransmission process is set for each of the plurality of configuration patterns. On the basis of mapping in a unique base frame determined by a pre-switchover conf iguration pattern and a post-switchover configuration pattern, a determination unit (206) determines a first retransmission process to be continued after switchover from among retransmission processes in the pre-switchover configuration pattern, and a second retransmission process to be continued from the first retransmission process from among retransmission processes in the post-switchover configuration pattern. |
