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: There is provided a communication system in which a base station apparatus communicates with a terminal apparatus and a communication apparatus flexibly designed to address diverse use cases so as to significantly enhance the transmission efficiency of the system as a whole. The communication apparatus includes an acquisition section that acquires information from an apparatus in wireless communication, and a control section that selects either orthogonal multiple access communication or non-orthogonal multiple access communication for communication with the apparatus on the basis of the information acquired by the acquisition section.
