Embodiment 1

[0041] The embodiment of this application provides a method for handling RLC failure, which is applied to network devices, such as image 3 shown, including:

[0042] Step S310, the first network device receives RLC failure related information of the user equipment UE.

[0043] Specifically, when the cells corresponding to a logical channel of the UE are all SCells, and the RLC entity corresponding to the logical channel fails (the number of retransmissions reaches or exceeds the maximum number of retransmissions), the UE reports the RLC failure related information to the network device. The information is that the first network device receives the RLC failure-related information sent by the user equipment UE, so as to subsequently perform RLC failure processing based on the RLC failure-related information.

[0044] Further, the one logical channel may be a logical channel for a UE configured with a CA-based duplication mechanism.

[0045] Step S320, based on the received RL...

Embodiment 2

[0050] The embodiment of the present application provides another possible implementation mode. On the basis of the first embodiment, the method shown in the second embodiment is also included, wherein,

[0051] The first network device is a centralized unit CU, and the second network device is a distributed unit DU; or, the first network device is a first base station, and the second network device is a second base station.

[0052] Step S320 specifically includes step S3201 (not marked in the figure) and step S3202 (not marked in the figure), wherein,

[0053] Step S3201: Send a first request message to a second network device.

[0054] Step S3202: Receive a first response message returned by the second network device for the first request message.

[0055] Specifically, the first request message includes at least one of the following:

[0056] Information about RLC failure;

[0057] Instruction information instructing the behavior of the network device to handle RLC fail...

Embodiment 3a

[0062] Embodiment 3a: (the CU decides to deal with the RLC failure: after receiving the information about the RLC failure sent by the UE, the CU performs the treatment)

[0063] Step 3a-1: sending the first request message to the DU through the CU;

[0064] Specifically, the first request message (such as a user context modification request message, UE Context ModificationRequest message), the content of the message can refer to TS38.473, and can further include at least one of the following:

[0065] ■RLC failure-related information can be at least one of the following information:

[0066] ■Information of the logical channel (such as logical channel identification information) corresponding to the RLC entity where the RLC failure occurs, and further, the cells associated with the RLC entity are all SCells;

[0067] The identification information of one or more cells corresponding to the RLC entity where the RLC failure occurred, further, the cells associated with the RLC en...

Abstract

The present application relates to the technical field of wireless communications, and discloses a method for processing an RLC failure, an electronic device, and a computer readable storage medium, the method for processing an RLC failure comprising: a first network device receives RLC failure related information of a user equipment UE; and based on the received RLC failure related information, performing corresponding processing on the RLC failure by interacting with the second network device. The embodiment of the invention discloses a method. Therefore, the first network equipment can directly interact with the second network equipment; therefore, the RLC failure can be directly determined to be processed according to the received RLC failure related information and interaction information reported by the UE, the RLC processing flow is simplified, the processing efficiency is improved, the RLC failure can be correctly and quickly solved, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular, the present application relates to a method for processing RLC failure, electronic equipment, and a computer storage medium. Background technique [0002] In NR (New Radio access, new wireless access) network or fifth-generation 5G network, in order to ensure the reliability of data transmission, a CA-based duplication mechanism (that is, a data packet repetition mechanism based on carrier aggregation) is defined, such as figure 1 shown. Among them, the PDCP (packet data convergence protocol, packet data convergence protocol) layer will copy the generated PDCP PDU (Protocol Data Unit, protocol data unit) into two copies, and send them to two different RLC (Radio link control, wireless link control) respectively. channel control) entities (such as RLC1 and RLC2), and then send them to the MAC (medium access control, media access control) layer through d...
