AI Technical Summary

Technical Problem

Existing wireless communications systems face challenges in managing delay status reporting (DSR) effectively, especially during congestion, which can lead to inefficient resource allocation and poor performance for latency-critical applications like extended reality (XR).

Method used

The proposed solution involves a method where user equipment (UE) receives signaling from the network equipment (NE) indicating congestion status and adjusts DSR reporting accordingly. During congestion, the UE suspends transmission of DSR reports for lower importance data packets, prioritizing higher importance packets and using importance level-based discarding techniques.

Benefits of technology

This approach reduces unnecessary DSR reporting during congestion, optimizing resource allocation and improving the reliability and latency of XR applications by prioritizing critical data packets.

Abstract

Various aspects of the present disclosure relate to managing delay status reporting (DSR) by a user equipment (UE) based on wireless communications system congestion. The techniques discussed herein provide multiple solutions that avoid unnecessary DSR reporting including cases where importance level based discarding is applied due to congestion in the wireless communications system. Conditions for DSR reporting, e.g., threshold based DSR reporting, are described for situations where importance level based discarding is enabled. In one solution threshold based DSR reporting is only allowed for certain PDU sets associated with a high importance level. For example, in one or more implementations the UE does not perform threshold based DSR reporting during time periods where importance level based discarding is enabled.
