<p>A fast retransmission method in radio link control layer acknowledged mode is provided by the invention, the method includes: a sender parses a status report to get unacknowledged (NACK) information; the sender determines needed retransmission data according to a judgement condition of the last group of NACK information, and sends the needed retransmission data encapsulated in a retransmission queue to a receiver. A fast retransmission device in radio link control layer acknowledged mode is also provided by the invention, the device includes: a status report reception unit, used to receive status reports from opposite end continuously; a status report parse unit, used to parse a status report to get NACK information; a status report judging and determining unit, used to determine needed retransmission data according to a judgement condition of the last group of NACK information; a data retransmission unit, used to send the retransmission data encapsulated in a retransmission queue to a receiver. Resource waste and time delay are avoided by adopting the method and device of the invention.</p> |
