  • data typically consists of multiple QoS flows, resulting in a very large volume of traffic.
  • XR service flows need to meet certain latency requirements during transmission, especially since some data flows need to arrive at the server simultaneously for decoding. Delay in any one data flow will cause the joint decoding of multiple data flows to fail.
  • network scheduling is dynamic. Therefore, in some cases, even if some data flows belong to low-priority logical channels, if some packets have not been scheduled for a long time, a Buffer State Report (BSR) needs to be sent to notify the network as soon as possible.
  • BSR Buffer State Report
  • a BSR can only be sent when high-priority logical channel data arrives, which cannot meet the needs of emergency scheduling. Therefore, optimizations for emergency scheduling in XR need to be considered.
