<p>A method and device for message retransmission, the method comprises the following steps: a first status report is constructed according to the message to be retransmitted; the message number of the Non-Acknowledgement(NACK) which is truncated by the available bandwidth from the first status report is read; the difference between the number of the front edge of the reception window and the message number is calculated; the difference and the given threshold are compared; the part before the site of truncation is taken as a second status report; a third status report is constructed according to the comparison result and the second status report; the third status report is sent by the receiving terminal; the message is retransmitted by the sending terminal according to the third status report. A message retransmission device is also provided, and includes a threshold comparison module, a status report constructing module, a status report sending module and a retransmission module. The method and device achieve that the air interface data transmission may be performed in time in various data transmission window status cases, and the data transmission speed and efficiency are improved.</p> |
