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.
