A terminal includes a transmission unit which transmits HARQ response information to transmission of a downlink-shared channel in one or more predetermined subframes based on resources of one or more uplink control channels. When a certain subframe in the predetermined subframes is a first subframe, a resource of an uplink control channel is given by an arithmetic operation using at least an initial value of a control channel element for use in transmitting a physical downlink control channel in the certain subframe and a first value configured by a higher layer. When a certain subframe in the predetermined subframes is a second subframe, a resource of an uplink control channel is given by an arithmetic operation using at least an initial value of a control channel element for use in transmitting a physical downlink control channel in the certain subframe and a second value configured by a higher layer.
