Patent ID: 8804650

Claim:
A wireless communication device, comprising: a reception section that is configured to receive a downlink signal in a first subframe from another wireless communication device; an ACK/NACK generation section that is configured to generate ACK/NACK which indicates an error determination result of the received downlink signal; a determination section that is configured, when an uplink signal directed to the wireless communication device is not allocated in a second subframe, to determine whether a different uplink signal is allocated in one or more third subframes, wherein the one or more third subframes are subframes subsequent to the first subframe by a determined number of subframes and previous to the second subframe; a multiplexing section that is configured to multiplex the ACK/NACK to the different uplink signal in the one or more third subframes when the determination section determines that the different uplink signal is allocated in the one or more third subframes; and a transmission section that is configured to transmit the different uplink signal in which the ACK/NACK is multiplexed by the multiplexing section.
