Claim 17:
18. A base station comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
control the transceiver to transmit, to a user equipment (UE), random access configuration information including mapping information between at least one random access occasion and at least one synchronization signal block (SSB) and a timing advance (TA) value,
control the transceiver to transmit the at least one SSB, and
control the transceiver to receive, from the UE, a random access preamble on a random access occasion corresponding to one of the at least one SSB,
wherein the random access preamble is received in response to listen before talk (LBT) being successful at the UE, the LBT being performed based on the TA value for the random access occasion.
