Method of beam failure recovery applied in sidelink user equipments and corresponding sidelink user equipment

Abstract

A method of beam failure recovery applied in sidelink (SL) user equipments (UEs) is provided. The method includes the following steps. Beam failure instances are detected by a first SL UE. A beam failure recovery procedure is triggered by the first SL UE when a number of the beam failure instances is equal or larger than an instance threshold. Under the beam failure recovery procedure, a new candidate beam is identified by a second SL UE which is a peer SL UE of the first SL UE. Under the beam failure recovery procedure, the new candidate beam and a UE identifier of the second SL UE is reported to the first SL UE by the second SL UE. Under the beam failure recovery procedure, a response from the first SL UE is monitored by the second SL UE.
