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. Obviously, 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 fall within 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.

[0034] Figure 5 It is a schematic flow chart of the method for optimizing the...

Abstract

The present invention provides a radio link control state report optimization transmission method and system, comprising: obtaining the original report field set in the NR RLC protocol state report format; adding the fourth report field, the first fragmentation judgment indicator field, and the tail fragmentation judgment The indication field and the segment offset position group number indication field of the intermediate segment are used to obtain an updated report field set; based on the updated report field set, the missing segments in the RLC data are segmented, and an RLC transmission status report is output. The present invention adds a new indication field to the existing NR RLC protocol, so that the radio link control layer does not need to carry all the field information when reporting the transmission status of the lost fragment, and greatly reduces the status report when indicating the lost fragment. At the same time, in the case of insufficient cache for sending status reports by the MAC, the number of times the status reports are sent can be effectively reduced, thereby reducing the feedback delay of the status reports.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for optimizing 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 encapsulating it into an...
