1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving system information including random access channel (RACH) configuration information;
identifying a reference subcarrier spacing based on a subcarrier spacing for a random access preamble;
identifying a symbol offset associated with a starting position of the random access preamble, based on the RACH configuration information;
determining a time resource for the random access preamble based on the symbol offset and the reference subcarrier spacing value; and
transmitting the random access preamble using the determined time resource.
