Abstract:
Disclosed are a method and an apparatus for beam failure recovery in a communication system. The method for beam failure recovery includes the steps of: searching for a plurality of candidate beams when a beam failure is detected; transmitting a beam failure recovery request signal to a base station by using beam #1 of the plurality of candidate beams; receiving a beam failure recovery response signal in response to the beam failure recovery request signal via beam #1 from the base station; and transmitting an SR requesting a resource for transmission of multi-beam setting information to the base station, wherein the multi-beam setting information includes indexes of one or more beams excluding beam #1 of the plurality of candidate beams. Therefore, performance of the communication system can be improved.
