Abstract: Embodiments of the present disclosure provide a transmission method and a device. The method includes: determining first spatial information; and receiving, in CSS and/or USS according to the first spatial information, a random access response message of a 2-step random access procedure triggered by beam failure recovery (BFR). The terminal can receive, in common search space and/or UE-specific search space, the random access response message of the 2-step random access procedure triggered by the beam failure recovery (BFR), so that reliability of a communications system can be improved.

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.
