Problems solved by technology

[0004] However, if the signal strength of the serving cell corresponding to the primary RLC entity is weak, the primary RLC entity is allocated more uplink data, which will cause the primary RLC entity to be too late to transmit uplink data, and the data allocation is not reasonable enough

Abstract

The invention discloses a data transmission method and device in a separate bearer mode and terminal equipment, and belongs to the technical field of communication. The method comprises the following steps: acquiring signal strengths of serving cells respectively corresponding to a first radio link control (RLC) entity and a second RLC entity, wherein the serving cell corresponding to the first RLC entity and the serving cell corresponding to the second RLC entity are in a main-auxiliary relationship; and performing allocation processing on the uplink data based on the signal strength of the serving cell corresponding to the first RLC entity and the signal strength of the serving cell corresponding to the second RLC entity, and determining the data allocation quantity of the first RLC entity and the data allocation quantity of the second RLC entity. According to the embodiment of the invention, the uplink data is allocated to the first RLC entity and the second RLC entity based on the signal strength of the serving cell in the separated bearing mode, so that the reasonable allocation of the uplink data is realized, and the stability of data transmission and the data throughput of a communication network are improved.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a data transmission method, device, and terminal device in a separate bearer mode. Background technique [0002] With the development of communication technology, 5GS (5th Generation System, fifth generation mobile communication system) has introduced various bearer types, such as Split (separated) bearer, MCG (Master Cell Group, main cell group) bearer, SCG ( Secondary Cell Group, secondary cell group) bearer, etc. [0003] Take UE (User Equipment, user equipment) side data transmission in a split bearer mode as an example. When the uplink data to be transmitted (such as the uplink data received by the PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) entity) exceeds the data separation threshold, the PDCP entity of the UE may choose to allocate the uplink data to the The PDCP entity is associated with a primary...
