Claim 15:
16. A base station in a wireless communication system, the base station comprising:
a transceiver; and
a controller configured to:
transmit, to a terminal via the transceiver, random access resource configuration information including random access channel (RACH) resource information associated with a synchronization signal (SS) and RACH resource information associated with a channel state information-reference signal (CSI-RS),
receive, from the terminal via the transceiver, a random access preamble based on a random access resource, and
transmit, to the terminal via the transceiver, a random access response,
wherein the random access resource is identified based on a measurement result of a CSI-RS, quasi-colocation (QCL) information, and the random access resource configuration information, and
wherein the QCL information indicates an SS quasi-colocated with the CSI-RS.
