1. A random access method, comprising:
sending, by a network device, at least one of a first synchronization signal/PBCH block (SSB) on a first candidate SSB occasion or a second SSB on a second candidate SSB occasion, wherein both the first candidate SSB occasion and the second candidate SSB occasion are associated with a first random access channel time-frequency-code resource; and
receiving, by the network device, random access information sent by a terminal device on the first random access channel time-frequency-code resource,
wherein the first candidate SSB occasion and the second candidate SSB occasion are comprised in L candidate SSB occasions,
wherein the L candidate SSB occasions include a first set and a second set of candidate SSB occasions,
wherein each of the first set and the second set of candidate SSB occasions includes M candidate SSB occasions adjacent in time sequence,
wherein the first set and the second set of candidate SSB occasions do not include candidate SSB occasions from each other,
wherein the M candidate SSB occasions in the first set of candidate SSB occasions include the first candidate SSB occasion,
wherein the M candidate SSB occasions in the second set of SSB include the second candidate SSB occasion, and
wherein a time sequence index of the first candidate SSB occasion in the M candidate SSB occasions and a time sequence index of the second candidate SSB occasion in the M candidate SSB occasions are same.
