Problems solved by technology

[0005] In view of the above analysis, the present invention aims to provide a method for sending status packets and an RLC receiving entity to solve the problem that when a status report cannot feed back a complete receiving situation in the prior art, due to the fact that the next status report must be at least in the state The packet can only be sent after the blocking timer expires, resulting in poor real-time performance of the status report, which causes a large load on the RLC sending entity

Embodiment Construction

[0025] Preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and are used together with the embodiments of the present invention to explain the principle of the present invention.

[0026] Please refer to figure 1 , is a schematic flowchart of the first embodiment of the sending status report of the present invention. figure 1 The method flow includes:

[0027] Step S11, the RLC receiving entity sends a status report to the RLC sending entity.

[0028] Wherein, the status report is used to reflect the receiving situation of the RLC PDU sent by the RLC sending entity. Specifically, the status report contains ACK_SN and NACK_SN. After receiving the status report, the RLC sending entity determines which PDUs have been confirmed by the RLC receiving entity through ACK_SN and NACK_SN, and which PDUs or PDU segments need to be retransm...

Abstract

The embodiment of the invention discloses a method for sending a status report. The method comprises the following steps that: a radio link control (RLC) receiving entity sends the status report to an RLC sending entity; and if the status report reflects part of the receiving situations of an RLC protocol data unit (PDU), which are sent to the RLC sending entity, a status packet stop timer is prohibited to be started, and after polling of the RLC sending entity is performed or a reordering timer overtimes, the RLC receiving entity resends the status report to the RLC sending entity, wherein the resent status report reflects the reminding receiving situations of the RLC PDU, which are sent to the RLC sending entity. By the embodiment of the invention, the problem of high load of the RLC sending entity caused by low real-time performance of the status report because the subsequent status report is sent when the status packet stop timer overtimes if the status report cannot reflect the complete receiving situations in the prior art can be solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for sending a status report and an RLC (Radio Link Control, radio link control) receiving entity. Background technique [0002] The RLC protocol layer is located under the PDCP (Packet Data Convergence Protocol) layer and above the MAC (Media Access Control) layer in the LTE (Long Term Evolution, long-term evolution) wireless interface protocol stack. A sublayer of layer 2. The RLC layer provides segmentation and retransmission services for user traffic data and control data. The functions of the RLC sublayer include link control, transfer of upper-layer PDU (Protocol Data Unit, protocol data unit), reassembly, segmentation, re-segmentation and concatenation, delivery of PDUs to the upper layer in sequence, ARQ (Automatic Repeat Request, automatic repeat transmission request) error correction, repeatability detection, flow control, protocol error detec...
