Abstract  Abstract

When carrier aggregation communication using a plurality of downlink component bands is applied, the overhead of downlink allocation control information can be suppressed while maintaining the quality of downlink data transmitted in each downlink component band. Terminal equipment and retransmission control method. In the terminal 200, the control unit 208 controls the transmission of the response signal based on a pattern of whether the downlink data received in the downlink component band included in the unit band group set in the own device is successful. Is done. Then, the control unit 208 changes the phase point of the response signal according to the number of downlink data that has been successfully received, that is, the number of ACKs in the pattern of whether or not the reception is successful, and the number of ACKs is the same. When there are a plurality of patterns of success or failure of reception, the phase points of the response signals are matched between the patterns of success or failure of reception.
