Embodiment Construction

[0032]In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention , but not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts all belong to the protection scope of the present invention.

[0033] Aiming at the problem of excessive overhead in the prior art, the present invention proposes a new method and system for optimizing the transmission of the status report of the radio link control layer, which can effectively reduce the overhead of the status report in the case of indicating lost fragments.

Abstract

The invention provides a radio link control status report optimized transmission method and system. The method comprises the following steps: acquiring an original report field set in an NR RLC protocol status report format; adding a fourth report field, a first fragment judgment indication field, a tail fragment judgment indication field and a fragment offset position group number indication field of a middle fragment to obtain an updated report field set; and based on the updated report field set, fragmenting the lost fragments in the RLC data, and outputting an RLC transmission state report. According to the invention, the new indication field is added in the existing NR RLC protocol, so that the radio link control layer does not need to carry all field information when reporting the transmission state of the lost fragment, the overhead of the state report under the condition of indicating the lost fragment is greatly reduced, and meanwhile, under the condition that the cache for sending the state report by the MAC is not enough, the sending times of the status report can be effectively reduced, so that the feedback time delay of the status report is reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and system for optimizing the transmission of a radio link control state report. Background technique [0002] In the new air interface (Next-generation Radio, NR) protocol, the radio link control (Radio LinkControl, RLC) layer is located in the packet data convergence protocol (Packet Data Convergence Protocol, PDCP) layer and the media access control (Media Access Control, MAC ) between layers. In the data sending entity, the RLC protocol layer forms an RLC service data unit (Service Data Unit, SDU) for the PDCP protocol data unit (ProtocolData Unit, PDU) delivered from the PDCP layer according to the scheduling result of the MAC layer for the corresponding logical channel and After adding the RLC header and encapsulating it into an RLC data PDU or fragmentation (fragmentation), a new RLC SDU is formed, then adding an RLC header and encapsulatin...
