Abstract

The present disclosure provides a radio bearer indication method and device, the method is used in a base station, and the method includes: configuring at least one transmission function for a radio bearer RB; configuring at least two transmission entities shared by each of the transmission functions ; adding first information to a first indication message, where the first information is used to characterize the transmission function and the transmission entity; sending the first indication message to the terminal, so that the terminal according to the The first indication message sets the transmission function and transmission entity corresponding to the RB. Therefore, the present disclosure can use at least two shared transmission entities to implement one or more transmission functions for the same RB, and improve the indication efficiency of radio bearers.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to a method and device for indicating a radio bearer. Background technique [0002] In related technologies, an RB (Radio Bearer, radio bearer) in an LTE (Long Term Evolution, long term evolution) system is a radio logical resource set. The RB refers to a segment of bearer between a UE (User Equipment, user equipment) and a base station. The RB is divided into SRB (Signaling Radio Bearer, signaling bearer) and DRB (Data Radio Bearer, data bearer) according to different bearer contents. In order to solve the reliability of data packets or signaling packets, in the 5G system, a packet duplication scheme has been allowed to be adopted at the PDCH (packet data convergence protocol) layer of the user plane. [0003] However, the prior art cannot realize the packet duplication scheme of the PDCH layer of the user plane. Contents of the invention [0004] In order to overcome t...
