Problems solved by technology

[0003] However, in the prior art, the RLC module will repeatedly put some retransmission data into the retransmission queue, so that the media access control layer (media access control, MAC) module reads the retransmission queue and repeatedly sends these retransmission data to the receiving end. In turn, the air interface sends repeated data, wasting the air interface resources of the sending end

Abstract

The invention relates to a retransmission method, a communication device, computer equipment and a readable storage medium. The method comprises the following steps: receiving a first state report, wherein the first state report is used for indicating first data which is not successfully received by a receiving end; before a first response message of the first status report is sent, if a second status report is received, sending the first response message and / or the second response message based on an overlapping relationship between the first data and the second data, wherein the second state report is used for indicating the second data which is not successfully received by the receiving end, and the second response message is a response message of the second state report. By adopting the method, the repeated sending probability of the retransmission data can be reduced, so that air interface resource waste caused by repeated sending of the retransmission data is reduced, and the air interface utilization rate is improved.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a data retransmission method, a communication device, a computer device and a readable storage medium. Background technique [0002] The radio link control layer (radio link control, RLC) is the user plane control layer of the protocol stack. The basic functions of the RLC in the uplink include: transmission of higher layer data, and a hybrid automatic repeat request (HARQ) function of an acknowledgment mode (acknowledge mode, AM). In this mechanism, the receiving end will send a receiving status report to the sending end, which is used to indicate to the sending end which data has been successfully received and which data has not been successfully received. The RLC module at the sending end can encapsulate the retransmission data packet according to the receiving status report, and retransmit the unsuccessfully received data packet to the receiving end.
