In an intermittent communication mode setting a mobile terminal periodically in an active and than again in a sleep mode, when a plurality of frames is available, the intermittent communication realizes an ARQ (Automatic Repeat Request) by securing Ack/Nack frames, automatically adding, when the AP sends Nack, a frame for retransmission and carrying out communications continuously. Thus, it is possible to enable retransmissions in an intermittent communication mode, prevent a standby state until the next timing of intermittent communication, and immediately communicate using the next frame for the retransmission and increase the amount of data which can be rescued by retransmissions. As a result, it is possible to reduce the probability of discarding packets and improve the transmission efficiency. This embodiment is particularly effective for Web access, etc. |
