Abstract

Provided is a terminal that is capable of avoiding a PHICH resource conflict where terminals having different UL-DL configurations coexist. When a response signal transmitted in a first sub-frame is in response to uplink data transmitted in a second sub-frame of a first configuration pattern, and a response signal transmitted in the first sub-frame is in response to uplink data transmitted in a third sub-frame of a second configuration pattern that is set on another terminal for which the configuration pattern setting cannot be changed, a first resource to be allocated to the response signal in the first sub-frame that is transmitted in response to the uplink data transmitted in the second sub-frame from the terminal; is different from a second resource to be allocated to the response signal in the third sub-frame that is transmitted in response to the uplink data transmitted from the another terminal.
