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: A data transmission method and a device are provided. The data transmission method is applied to a terminal and includes: in the case that both a grant-free resource and a grant-based resource are available for the terminal, choosing, by the terminal, to transmit service data on the grant-free resource preferentially; or choosing, by the terminal, to transmit service data on the grant-based resource preferentially; or choosing dynamically, by the terminal, to transmit service data on the grant-free resource and/or the grant-based resource.
