Abstract: An information transmission method for a random access process includes: obtaining a preset mapping relationship between a physical uplink shared channel resource and a physical random access channel resource; and sending a random access message on a random access resource according to the preset mapping relationship. The random access resource comprises the PUSCH resource and the PRACH resource. When a random access channel occasion corresponding to the PRACH resource is not associated with an SSB, the RO is not associated with the PUSCH resource.

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.
