1. An information transmission method for a random access procedure, applied to a terminal side and comprising:
obtaining a mapping relationship between interlaces of physical random access channel (PRACH) resources and physical uplink shared channel (PUSCH) resources, wherein the interlace comprises at least one PRACH resource unit, wherein one PRACH resource unit corresponds to one random access preamble in one random access channel occasion (RO); and
sending a random access message on a random access resource according to the mapping relationship, wherein the random access resource comprises the PUSCH resources and the PRACH resources;
wherein the mapping relationship comprises:
the PRACH resources are mapped to the PUSCH resources in an ascending order of random access preamble indexes in one RO; or,
the PRACH resources are mapped to the PUSCH resources in an ascending order of DMRS port indexes in one physical uplink shared channel occasion (PUO).
