Abstract:
Aspects relate to mechanisms for wireless communication devices to reset a beam. A UE identifies a list of a plurality of component carriers (CCs). The UE detects a beam failure on a first CC of the plurality of CCs. The UE transmits a beam failure recovery request including a candidate beam indication of a candidate beam to a base station. The base station receives the beam failure recovery request and transmits a beam failure recovery response to the UE. The UE receives the beam failure recovery response and applies the candidate beam to at least one CC of the plurality of CCs. The UE may apply the candidate beam to every CC or to only the first CC. The UE may apply the candidate beam to the at least one CC of the plurality of CCs following a predetermined number of symbols after receiving the beam failure recovery response.
