ABSTRACT:
A radio transmission apparatus and a radio transmission method for readily controlling retransmission timing presets a frame cycle for retransmission, and transmits only packets for which no acknowledgement of receipt has been received within the frame cycle as a reply from a receiving apparatus to a transmitting apparatus. Thus, timing for retransmission can be readily determined. Also, the retransmission timing is determined based on when a packet is actually transmitted. Therefore, multiple acknowledgements of receipt can be returned as a combined reply.
