Claim 5:
6. A method of random access, applied to a user equipment UE, and comprising:
receiving a broadcast message transmitted from a base station, 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
transmitting the random access preamble sequence to the base station by using the second physical resource corresponding to the supplementary resource indication information when no first reference SSB synchronization signal is detected on physical resource occupied by the first reference SSB synchronization signal.
