摘要
A method of a user equipment (UE) for multi-beam operation in a wireless communication system is provided. The method comprises receiving, from a base station (BS), configuration information for a search space in which to receive a response to a beam failure recovery request, monitoring at least a channel state information reference signal (CSI-RS) included in a first set of reference signals to detect a beam failure event based on a threshold, measuring at least one of a reference signal received power (RSRP) of the CSI-RS or an RSRP of synchronization signal/physical broadcasting channel (SS/PBCH) blocks in a second set of reference signals when the beam failure event is detected, identifying a new candidate beam based on the measured RSRPs, and transmitting, to the BS, the beam failure recovery request over a physical random access channel (PRACH) based on detection of the beam failure event.
