Abstract
Disclosed are a beam failure recovery method, device, and apparatus, comprising: a terminal determining that performing beam failure recovery is required; and the terminal initiating random access to perform the beam failure recovery on a selected bandwidth part, and the bandwidth part is not changed in the random access process. By adopting the present disclosure, a terminal configuring each bandwidth part will not cause a disorderly beam failure recovery process. The terminal can select an appropriate bandwidth part and a synchronization signal block or channel state information reference signal thereon to initiate the beam failure recovery process. The disclosure achieves fast beam recovery while minimizing impact on data transmission. Further, a base station is also for determining how the terminal performs the beam failure recovery, to make a timely response, to ensure effective transmission of data without wasting random access resources.
