Abstract: Feedback of a plurality of pieces of SL-HARQ-ACK in sidelink communication is controlled. A communication device (terminal device 2) includes a reception unit (205), a transmission unit (207), and a control unit (203). The reception unit (205) receives a sidelink shared channel for sidelink communication that is device-to-device communication. The transmission unit (207) transmits a first sidelink feedback channel and a second sidelink feedback channel for transmitting response information of the sidelink shared channel. The control unit (203) performs control to select the first sidelink feedback channel and the second sidelink feedback channel, and to cause the transmission unit to transmit the selected result.

Abstract: A communication device (40) includes a control unit (45). The control unit (45) receives an instruction to perform channel sensing in an unlicensed band, from a base station apparatus (20). The control unit (45) performs the channel sensing in a channel occupancy time in which the instruction is received. The control unit (45) transmits second uplink control information that can be multiplexed with first uplink control information and that indicates a result of the channel sensing, to the base station apparatus (20), in the channel occupancy time.
