Abstract
The invention provides a method performed by user equipment and user equipment. The user equipment is configured in a discontinuous reception (DRX) mode. The method performed by user equipment comprising: initiating a random access (RA) procedure if a value of a beam failure instance (BFI) counter is greater than or equal to a threshold, the threshold being configured by an information element (IE) beamFailureInstanceMaxCount; transmitting a RA preamble; starting a RA response window, the RA response window being configured in an IE BeamFailureRecoveryConfig; and monitoring a PDCCH on a search space indicated by an IE RecoverySearchSpaceId while the RA response window is running. The user equipment can reliably complete a procedure to recover from beam failure even if the user equipment is configured in a DRX mode, thereby improving the overall reliability and communication efficiency of a communication system related to the user equipment.
