An electronic device may establish a beam pair link, using a first Tx beam included in a plurality of Tx beams having different directions transmitted from a base station, and a first Rx beam included in a plurality of Rx beams, may receive information associated with the plurality of Tx beams, using the beam pair link, may receive a plurality of first signal blocks, using the beam pair link, may perform first decoding of the first signal blocks, may determine beam failure for the first Tx beam based at least partly on the result of the first decoding, may identify measurement information about the plurality of Tx beams, and may determine RLF associated with the base station based on the measurement information and information associated with the Tx beams.
