1. A method by a terminal for performing a random access in a wireless communication system, the method comprising:
receiving a message including first information for configuring an uplink (UL), second information for configuring a supplementary uplink (SUL), and third information for performing the random access from a base station;
receiving a synchronization signal (SS) and physical broadcast channel (PBCH) block (SSB) from the base station;
measuring a reference signal received power (RSRP) based on a secondary synchronization signal (SSS) included in the SSB;
comparing the RSRP with a threshold value included in the third information for performing the random access;
determining one carrier of an UL carrier or an SUL carrier to perform the random access based on a result of a comparison; and
transmitting a random access preamble on the determined carrier based on the first information or the second information.
