1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, system information including configuration information on a supplementary uplink (SUL) of a cell associated with the base station, and information on an offset applied for a random access on the cell, wherein an uplink (UL) of the cell and the SUL of the cell are configured for one downlink of the cell, and wherein the configuration information on the SUL of the cell includes information on a threshold;
selecting the SUL for the random access from the UL and the SUL based on the information on the threshold and a reference signal received power (RSRP) measured for the one downlink of the cell;
determining a transmission timing for an uplink signal for the random access to be transmitted on the SUL based on a value indicated by the information on the offset, wherein the value indicated by the information on the offset is included in a plurality of values, and wherein the plurality of the values are defined based on a duplex mode of the cell in which a transmission of the uplink signal takes place and a frequency range of the cell; and
transmitting, to the base station, the uplink signal on the SUL based on the determined transmission timing.
