Latency status reporting for extended reality services
By prioritizing the DSR and PSI dropping mechanism at the UE and network nodes, the problem of ineffective prioritization of DSR and PSI in existing wireless communication technologies is solved, thereby improving the reliability and latency performance of XR services.

AI Technical Summary
In existing technologies, the Delay Status Report (DSR) and the discarding mechanism based on Protocol Data Unit (PDU) set importance (PSI) fail to effectively prioritize in wireless communication, resulting in degraded wireless network performance, especially in extended reality (XR) services where the requirements for high reliability and low latency cannot be met.
Dynamic management of delay and dropping is achieved by identifying and sending Delay Status Reports (DSRs) and PSI-based dropping mechanisms at the User Equipment (UE) level, prioritizing Buffer Status Reports (BSRs), and receiving and processing these reports at network nodes to adjust Radio Resource Management (RRM) policies.
It improves the reliability and latency performance of XR services, and enhances the overall performance of the wireless network without sacrificing latency by appropriately adjusting the RRM strategy.
