Claim 17:
18. A base station, comprising:
a processor; and
a memory, configured to store instructions executable by the processor,
wherein the processor is configured to:
group multiple Synchronization Signal Blocks (SSBs) and select a primary SSB from each SSB group;
send indication information to User Equipment (UE), the indication information indicating a primary SSB to be sent in an SSB group to be sent;
send at most one SSB in each SSB group to be sent to the UE; and
send the number of SSBs corresponding to preambles in each Random Access Channel (RACH) Occasion (RO) and the number of ROs under Frequency Division Multiplexing (FDM) to the UE, to enable the UE to determine corresponding RO and preamble of the primary SSB based on the SSB to be sent by the base station, a position of the primary SSB in the SSB to be sent by the base station, the number of SSBs corresponding to preambles in each RO and the number of ROs under the FDM, to realize RA to the base station.
