Claim 9:
10. A user equipment (UE) comprising:
a transceiver; and
a processor coupled with the transceiver and configured to:
control the transceiver to receive, from a base station, 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 receive an SSB from the base station,
identify a random access occasion corresponding to the received SSB and the TA value for the random access occasion based on the random access configuration information,
perform listen before talk (LBT) based on the identified TA value, and
control the transceiver to transmit, in response to the LBT being successful, a random access preamble on the identified random access occasion.
