1. A method performed by a terminal in a wireless communication system, the method comprising:
obtaining 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);
identifying a random access resource based on a measurement result of a CSI-RS, quasi-colocation (QCL) information, and the random access resource configuration information, wherein the QCL information indicates an SS quasi-colocated with the CSI-RS; and
transmitting a random access preamble based on the random access resource.
