Abstract: A method for determining beam failure recovery, a terminal device, and a non-transitory computer-readable storage medium are provided. The method includes in a case of a beam failure, initiating a contention-based random access process triggered for beam failure recovery. The method further includes receiving a downlink response message and determining that the beam failure recovery is completed. The downlink response message is a response message corresponding to the random access process.
