Claim 0:
1. A method of implementing beam failure recovery (BFR) for a multi-transmission-and-reception-point (M-TRP) transmission comprising a first transmission from a first TRP and a second transmission from a second TRP, the method comprising:
receiving, by a user equipment (UE), a first set of reference signals (RSs) corresponding to the first TRP and a second set of RSs corresponding to the second TRP, the first set of reference signals corresponding to the first TRP including a first subset of reference signals and a second subset of reference signals;
determining, by the UE, that the first set of RSs indicates a beam failure instance (BFI) specific to the first TRP, and responsively updating a first BFI counter specific to the first TRP based on the first subset of reference signals;
determining, by UE, that a beam failure with respect to the first TRP has occurred based on a count of the first BFI counter equaling or surpassing a first BFI counter threshold;
selecting a candidate replacement beam from the second subset of reference signals; and
performing, by the UE, a BFR process for the first TRP based on the candidate replacement beam, responsive to determining that the beam failure with respect to the first TRP has occurred.
