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.

Abstract: There is proposed a mechanism that makes it possible to achieve fair channel access between a plurality of nodes. A base station including a control unit (150) that notifies a terminal device of setting information regarding a channel access scheme to be used and carrier sense. The terminal device is configured to use, as channel access schemes, a first scheme in which the terminal device performs carrier sense at any timing and a second scheme in which the terminal device performs carrier sense at predetermined timing.
