'Method for fast relay in a recognized mode of radio link control layer and apparatus for fast relay in recognized mode of radio link control'

摘要

The present invention discloses a method for fast retransmission in radio link control layer acknowledged mode, which comprises the following steps of: a sending end analyzing a status report to obtain unacknowledged (NACK) information; the sending end determining data that need to be retransmitted according to a judging condition of a last group of NACK information, and placing the data into a retransmission queue and sending the data to a receiving end after packeting. The present invention further discloses an apparatus for fast retransmission in a radio link control layer acknowledged mode, comprising: a status report receiving unit for receiving status reports from an opposite end continuously; a status report analyzing unit for analyzing status reports to obtain NACK information; a status report judging and determining unit for determining data that need to be retransmitted according to a judging condition of a last group of NACK information; and a data retransmitting unit for sending retransmission data to a receiving end after packeting in a retransmission queue. The method and apparatus of the present invention can avoid resource waste and time delay.
