Abstract:
A method and a device for beam failure recovery are provided. The method includes determining signal quality of a designated beam being out of a required range of control channel transmission, where the designated beam is designated by a network for control channel transmission; performing a beam measurement to determine a plurality of recommended beams, where signal quality of the plurality of recommended beams is within a preset range; and reporting beam identifications of the plurality of recommended beams to the network, so that the network can change the designated beam based on the plurality of recommended beams. The method and device can increase a success rate of beam failure recovery.
