Claim 14:
15. A first base station in a wireless communication system, comprising:
a transceiver configured to transmit and receive signals; and
at least one processor configured to:
receive, from a second base station via the transceiver, a random access configuration of the 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, and
transmit, to a terminal via the transceiver, an radio resource control (RRC) message including the received random access configuration of the second base station,

wherein a random access preamble is transmitted from the terminal to the second base station on a random access preamble transmission resource identified 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.
