Abstract:
A plurality of scheduled entities, such as transmission reception points (TRPs), may each transmit at least one TRP-specific beam failure detection reference signal (BFD-RS) having a corresponding TRP identifier (ID) to a scheduled entity. The scheduled entity may be configured with at least one TRP-specific medium access control (MAC) parameter. The scheduled entity may receive the TRP-specific BFD-RSs and respective TRP IDs associated therewith. The scheduled entity may measure each BFD-RSs and count beam failure instances associated with each TRP ID. The scheduled entity may transmit a beam failure recovery request (BFRQ) associated with the respective TRP ID in response to a predetermined quantity of respective TRP-specific BFD-RS measurements of at least one of the respective TRP-specific BFD-RSs being less than a predetermined value. A scheduling entity may receive the BFRQ, where the at least one TRP-specific MAC parameter was used to trigger the BFRQ.
