Abstract: The present disclosure provides apparatuses and methods for establishing a random access. The apparatuses include a terminal which comprises circuitry which, in operation, generates a first random access preamble; and a transmitter which, in operation, transmits the first random access preamble to a base station on a first physical random access channel (PRACH) occasion (RO) among a plurality of RO candidates, the plurality of RO candidates being determined based on PRACH configuration information received from the base station, wherein the first RO is assigned within a first frequency region, the first frequency region being equal to a first sub-band in which a listen before talk (LBT) procedure is performed at the terminal.
