AI Technical Summary

Technical Problem

In communication systems, there is a problem that the accuracy of uplink resource scheduling is not high, especially in extended reality (XR) services, the delay of data streams is high, and the delay of any data stream will cause the joint decoding of multiple data streams to fail.

Method used

By sending indication information between the PDCP entity and the RLC entity, the target data packet with a remaining time below the first threshold is indicated, so that the RLC entity can know which data packets need to be urgently scheduled, and improve the accuracy of the amount of data reported by the DSR.

Benefits of technology

Improve the accuracy of uplink resource scheduling, ensure the delay requirement of data streams in XR service, and reduce the joint decoding failure of multiple data streams due to delay.

Abstract

Provided in the embodiments of the present disclosure are an information transmission method, and a PDCP entity, an RLC entity, a terminal and a storage medium. The information transmission method comprises: a packet data convergence protocol (PDCP) entity of a terminal sending indication information to a radio link control (RLC) entity, wherein the indication information is used for indicating a target data packet for which the remaining duration is lower than a first threshold value.
