Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a base station a reception method and an integrated circuit which is when applying carrier aggregation communication using plural downstream unit bands capable of maintaining the quality of the data transmitted with downstream unit bands through the downstream channel while controlling the overhead of downstream allocation control information.

SOLUTION: A terminal (200) includes a control unit (208) that controls the transmission of a response signal on the basis of a reception success/failure pattern of a data of the downstream channel which is received with a downstream unit band included in a unit band group preset in the terminal (200). The control unit (208) varies the phase point of the response signal according to the number of data of the downstream channel which are successfully received in the reception success/failure patterns; i.e. the number of ACKs. When there are plural patterns of the reception success/failure which have the same number of ACKs the control unit (208) controls so that phase points of the response signals are the identical to each other among the reception success/failure patterns.
