1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information, wherein the configuration information includes information on a supplementary uplink (SUL) threshold value and information on a threshold value for 2-step random access;
identifying whether a reference signal received power (RSRP) of downlink path loss is smaller than the SUL threshold value;
selecting an SUL carrier for performing a random access procedure in case that the RSRP is smaller than the SUL threshold value;
selecting a normal uplink (NUL) carrier for performing the random access procedure in case that the RSRP is larger than or equal to the SUL threshold value; and
after the selecting of the SUL carrier or the NUL carrier,
identifying whether the RSRP is larger than the threshold value for a 2-step random access,
determining a random access type as the 2-step random access in case that the RSRP is larger than the threshold value, and
determining the random access type as a 4-step random access in case that the RSRP is not larger than the threshold value.
