Claim 0:
1. A method of random access, applied to a base station, and comprising:
transmitting a broadcast message to a user equipment (UE), wherein the broadcast message comprises physical random access channel (PRACH) configuration information and supplementary resource indication information; wherein the PRACH configuration information comprises:
first indication information for characterizing first physical resource and
second indication information for characterizing a random access preamble sequence; and

wherein the supplementary resource indication information is used for characterizing second physical resource;
obtaining a location of a first reference synchronization broadcast block (SSB) synchronization signal according to the first physical resource corresponding to the PRACH configuration information, wherein the first reference SSB synchronization signal is at a synchronization signal transmission period most proximate to the first physical resource and before the first physical resource; and
monitoring the random access preamble sequence on the second physical resource corresponding to the supplementary resource indication information when the first reference SSB synchronization signal is unsuccessfully transmitted.
