In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE establishes a connection supporting an extended reality (XR) application service with a base station. The UE reports, to the base station under a trigger condition, a buffer status report (BSR) to indicate a buffer size for data to be transmitted to the base station. The BSR includes information related to a corresponding BSR table. The UE receives a configuration instruction from the base station. The UE configures resources on the UE.
