Claim 9:
10. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to transmit and receive signals; and
at least one processor configured to:
receive, from a first base station via the transceiver, a radio resource control (RRC) message including a random access configuration of a second base station, the random access configuration including information on dedicated random access preamble transmission resources for one or more downlink (DL) transmission (TX) beams of the second base station,
identify a DL TX beam among the one or more DL TX beams of the second base station,
identify a random access preamble transmission resource corresponding to the identified DL TX beam among the dedicated random access preamble transmission resources for the one or more DL TX beams in the random access configuration of the second base station, and
transmit, to the second base station via the transceiver, a random access preamble on the random access preamble transmission resource.
