1. An apparatus for wireless communication at a user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to:
obtain a first indication, based at least in part on a first threshold, that a hybrid automatic repeat request (HARQ) discontinuous transmission (DTX) is caused by a listen-before-talk (LBT) failure;
obtain a second indication, based at least in part on a second threshold, that the HARQ DTX caused by the LBT failure is a type of HARQ DTX that is to be counted for identifying a sidelink radio link failure (RLF); and
identify the sidelink RLF based at least in part on detecting a number of consecutive occurrences of the type of HARQ DTX occurrences.
