PROBLEM TO BE SOLVED: To improve throughput and delay time, and to equalize transmission chance of uplink and downlink, in a radio network system for bidirectional communication of radio packet between one access point and a plurality of terminals. SOLUTION: An access point comprises a plurality of transmission buffers corresponding to a plurality of respective terminals, to independently operate channel accesses for packet transmission from transmission buffers to corresponding terminals. The terminal transmits by adding a packet with information (next packet information) about presence or size of the packet which is scheduled to be transmitted next. The access point extracts and registers the next packet information of that terminal when receiving the packet transmitted from the terminal, and registers the next packet information of the transmission buffer when the packet addressed to the terminal is transmitted, for management.
