Abstract:
The present disclosure is directed to a random access method and apparatus, user equipment, and a computer readable storage medium. The random access method comprises: determining, according to received configuration information, a random access policy adopted by current UE, the configuration information comprising different policies for instructing random access; determining an uplink physical random access channel (PRACH) resource corresponding to the adopted policy; and sending a preamble sequence to a base station on the basis of the determined uplink PRACH resource. According to the present disclosure, different policies for instructing random access are comprised in configuration information, such that UE can determine, according to received configuration information, a random access policy to be adopted by the UE, and determine an uplink PRACH resource corresponding to the adopted policy, and then send a preamble sequence to a base station on the basis of the determined uplink PRACH resource, meeting configuration requirements and access requirements of large systems with high frequency ranges.
