<p><P>PROBLEM TO BE SOLVED: To provide a communication control technique that efficiently performs retransmission to recover from a frame failure. <P>SOLUTION: A receiving side communication device obtains a retransmission data amount indicating an amount of data which requires continuous retransmission, determines, based on the retransmission data amount, final frame information to identify a final frame in a frame group requiring continuous retransmission from a frame at which a failure occurred, creates a NAK frame including at least request frame information to identify a head frame in the frame group and the final frame information, and transmits the created NAK frame. A transmission side communication device receives the NAK frame, sequentially reads out each retransmission frame from the head frame to the final frame identified based on the request frame information and the final frame information included in the received NAK frame from a storage unit storing a transmission frame, and continuously transmits each read-out retransmission frame. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
