Description

Data transmission method, device, user terminal, network node, computer-readable storage Medium

Technical field

The present invention relates to wireless communication technology field, a kind of data transmission method, device, user terminal, net are particularly related to Network node, computer readable storage medium.

Background technique

As shown in Figure 1, UE (User Equipment, user terminal) is in a cell group such as SCG (Secondary Cell Group, secondary cell group) on connection be will be in another cell group such as MCG (Master Cell Group, main plot group) A part of data distribution transmission on DRB (Data Radio Bearer, Data Radio Bearer), the PDCP (Packet of the carrying Data Convergence Protocol, Packet Data Convergence Protocol) entity is still 1, and corresponding two cell groups have respectively From independent RLC (Radio Link Control, radio link layer control protocol) entity and MAC (Media Access Control, media access control) entity.This PDCP data pass through the carrying that MCG and SCG is sent simultaneously and are known as separating carrying (split bearer)。

In the prior art, the number that UE can cache its each logic channel group (LCG, Logical Channel Group) Network side is reported to by BSR (Buffer Status Report, buffer status report) according to amount, the data volume of the caching can wrap Include the data volume of all cachings in the corresponding PDCP entity of each logic channel in LCG and RLC entity.In one logic channel group It may include one or more logic channels, the corresponding 1 PDCP entity of each logic channel and 1 RLC entity.

When carrying out transmitting uplink data, when the data volume of PDCP entity caching is less than the threshold value of network side configuration, PDCP entity sends the data to 1 paths (such as MCG or SCG) of network configuration, i.e. UE is when reporting BSR by PDCP reality Data in body are reported to network side as the data in 1 paths.When the data volume of PDCP entity caching is greater than or equal to net Network side configuration threshold value when, PDCP entity is sent the data to mulitpath (i.e. MCG and SCG), i.e. UE report BSR when It waits and is reported to network side respectively for the data in PDCP entity as the data in mulitpath.

As can be seen that the path that current UE sends data only considers the data volume of PDCP entity caching, other are not accounted for The parameters such as the signal quality in the such as different paths of factor, can not achieve data and more effectively transmit.
