Claim 8:
9. A method for Random Access (RA), applied to User Equipment (UE), comprising:
receiving and detecting a Synchronization Signal Block (SSB) from a base station;
determining a primary SSB in an SSB group corresponding to the detected SSB;
receiving indication information from the base station, and determining, based on the indication information, an SSB to be sent by the base station;
receiving 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) from the base station, and determining 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
sending the corresponding preamble to the base station on the determined RO to realize RA to the base station.
