Claim 18:
19. User Equipment (UE), comprising:
a processor; and
a memory, configured to store instructions executable by the processor,
wherein the processor is configured to:
receive and detect a Synchronization Signal Block (SSB) from a base station;
determine a primary SSB in an SSB group corresponding to the detected SSB;
receive indication information from the base station, and determine, based on the indication information, an SSB to be sent by the base station;
receive a number of SSBs corresponding to preambles in each Random Access Channel (RACH) Occasion (RO) and a number of ROs under Frequency Division Multiplexing (FDM) from the base station, and 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 the preambles in each RO and the number of ROs under the FDM; and
send the corresponding preamble to the base station on the determined RO to realize RA to the base station.
