19. A method for wireless communications performed at a first user equipment (UE), comprising:
sending a first sidelink communication to a second UE using a first beam pair of a unicast link with the second UE, wherein the first beam pair includes a first transmission beam and a first reception beam;
detect a fault associated with at least one of the first transmission beam or the first reception beam;
based on the detected fault, updating a value of at least one discontinuous transmission (DTX) count associated with at least one of the first transmission beam or the first reception beam;
determining that the value of the at least one DTX count meets a threshold; and
based on the value of the at least one DTX count meeting the threshold, initiating at least one of beam refinement or beam recovery of the first beam pair.
