Abstract
Certain aspects of the present disclosure provide to techniques for radio link monitoring (RLM), detecting beam failure, and beam failure recovery (BFR) using radio link monitoring reference signal (RML-RS) resources and beam failure recovery reference signal (BFR-RS) resources. An exemplary method by a user equipment (UE) may include obtaining a first configuration indicating one or more radio link monitoring reference signal (RLM-RS) resources and one or more beam failure recovery reference signal (BFR-RS) resources, wherein each RLM-RS resource corresponds to at least a first link, and each BFR-RS resource corresponds to at least a second link, obtaining a first indication that a first link quality for the first link is below a first threshold and a second link quality for the second link is above a second threshold, and taking action regarding a radio link failure (RLF) based on the indication.
