Claim 8:
9. A method for establishing an initial access, the method comprising:
receiving, at a terminal, candidate synchronization signal/physical broadcast channel blocks (SSBs) in a synchronization signal (SS) burst set, the candidate SSBs being transmitted within one or more SSB channel occupancy time (SSB COT) from a base station; and
transmitting, from the terminal, a physical random access channel (PRACH) preamble on a PRACH occasion (RO) to the base station, the RO being associated with one SSB among the received candidate SSBs,
wherein the number of the one or more SSB COT is determined according to a result of a listen before talk (LBT) procedure carried out at the base station, and
wherein the number of the one or more SSB COT is one if the result of the LBT procedure indicates that a duration of a first of the one or more SSB COT is not less than that required to transmit the candidate SSBs in the SS burst set; otherwise the number of the one or more SSB COT is two or more.
