Classification: CPC H | IPC H

Claim 0:
1. A method of wireless communication by a first sidelink user equipment (UE), comprising:
periodically receiving a first set of sidelink beam failure detection (BFD) reference signals (RSs) from a second sidelink UE, the first set comprising a plurality of reference signals;
incrementing a beam failure detection counter in response to all of the reference signals of the first set of sidelink beam failure detection reference signals having a received signal strength below a threshold;
starting a beam failure detection timer in response to the first set of sidelink beam failure detection reference signals having the received signal strength below the threshold;
declaring a beam failure before the beam failure detection counter reaches a maximum beam failure detection counter value, prior to transmitting a second set of sidelink beam failure detection reference signals, in response to transitioning to a transmitting role to transmit the second set of sidelink beam failure detection reference signals (RSs).
