Abstract: Apparatuses and methods for beam failure recovery in a wireless communication system. A method for operating a user equipment (UE) includes receiving a first pair of reference signal (RS) sets including (i) a first set of RSs for detecting a first beam failure and (ii) a second set of RSs for identifying a first candidate beam for recovering the first beam failure and receiving a second pair of RS sets including (i) a third set of RSs for detecting a second beam failure and (ii) a fourth set of RSs for identifying a second candidate beam for recovering the second beam failure. The method further includes detecting the first or second beam failure; identifying a physical uplink control channel (PUCCH) resource for transmission of a recovery request for the detected first or second beam failure; and transmitting a first signal to request recovery of the first or second beam failure using the PUCCH resource.
