摘要： A communication apparatus improves the throughput of a whole communication system while performing contention distributed control which provides equality of a transmission chance by observing a medium occupation state. The communication apparatus includes a back-off process section for performing, using a contention window, a regular back-off process which is performed at transmission of a transmission frame and a pseudo back-off process which is performed in a pseudo manner when the transmission frame is not transmitted. The communication apparatus also includes a medium information obtaining section for obtaining, by the pseudo back-off process, medium information indicative of a state of the transmission line medium when the transmission frame is not transmitted, and a medium state determination section for determining the state of the transmission line medium using the medium information to obtain determination information.
