Beam measurement relaxation criteria and configuration
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, an indication of a relaxation criterion associated with one or more reference signals used in performing at least one of radio link monitoring (RLM) or beam failure detection (BFD), wherein the relaxation criterion includes a mobility condition associated with the UE. The UE may perform, based at least in part on satisfying the mobility condition, one or more measurements using one or more of the reference signals and based at least in part on the relaxation criterion. Numerous other aspects are described.
