PROBLEM TO BE SOLVED: To reduce a delay due to data retransmission in relay transmission.SOLUTION: In a receiver, a receiver unit receives data packets, which store data, burst-by-burst. Further, a demodulation unit demodulates each data packet. A transmitter unit transmits a retransmission request information of retransmission request data packets burst-by-burst to request retransmission. A retransmission request unit sequentially detects the retransmission request data packets from data packets on which demodulation is completed, to generate the retransmission request information of the retransmission request data packets detected before a time point of transmission by the transmitter unit, as the retransmission request information of the present burst.SELECTED DRAWING: Figure 3 |
