Abstract: The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate than a post-4th Generation (4G) communication system such as long-term evolution (LTE). A method of performing random access by a user equipment (UE) in a wireless communication system is provided. The method includes receiving a first signal including at least one reference signal from a base station (BS), measuring the at least one reference signal and transmitting a second signal to the BS through first uplink resources corresponding to a selected reference signal, and transmitting a random access preamble through a physical random access channel (PRACH) resource corresponding to the selected reference signal.
