Abstract

The present invention provides a method and device for indicating a radio bearer. The method for indicating a radio bearer is applied to a base station, and includes the steps: configuring at least one transmission function for a radio bearer RB; configuring at least two transmission entities which are shared by each of the transmission functions; adding first information into a first indication message which is used to characterize the transmission function and the transmission entities; and transmitting the first indication message to a terminal so as to enable the terminal to set the transmission function and the transmission entities corresponding to the RB according to the first indication message. Therefore, the method for indicating a radio bearer can implement one or more transmission functions by using the at least two shared transmission entities for the same RB, can improve the indication efficiency of the radio bearer.

Description

Technical field [0001] The present disclosure relates to the field of communications, and in particular to a method and device for indicating radio bearers. Background technique [0002] In related technologies, an RB (Radio Bearer, radio bearer) in an LTE (Long Term Evolution) system is a collection of wireless logical resources. The RB refers to a section of bearer between a UE (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, it has been allowed to adopt a packet duplication scheme at the PDCH (packet data convergence protocol) layer of the user plane. [0003] However, the prior art still cannot realize the packet duplication scheme of the PDCH layer of the user plane. Summary of the invention [0004] In order to overcome the problems in the related a...
