1. A random access transmission method, applied to a terminal side and comprising:
obtaining resource allocation information for random access, wherein the resource allocation information indicates at least two candidate random access resources, and the candidate random access resources comprise candidate resources for sending data and candidate resources for sending control information corresponding to the candidate resources for sending data;
selecting a target random access resource from the at least two candidate random access resources according to a preset selection rule; and
sending a random access request message over the target random access resource, wherein the random access request message comprises MsgA (Message A) of a 2-step random access procedure;
wherein the step of selecting a target random access resource from the at least two candidate random access resources according to a preset selection rule comprises:
selecting a target control information transmission resource from the candidate resources for sending control information in the at least two candidate random access resources according to the preset selection rule;
selecting a target data transmission resource from the candidate resources for sending data that are corresponding to the target control information transmission resource; and
determining the target control information transmission resource and the target data transmission resource as the target random access resource.
