1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, a primary synchronization signal (PSS) and a secondary synchronization signal (SSS) based on a first subcarrier spacing;
receiving, from the base station, a master information block (MIB) based on the first subcarrier spacing, the MIB including information associated with a second subcarrier spacing;
receiving, from the base station, a system information block 1 (SIB1) based on the second subcarrier spacing, the SIB1 including information associated with a third subcarrier spacing;
transmitting, to the base station, a random access preamble based on the third subcarrier spacing; and
receiving, from the base station, a random access response based on the second subcarrier spacing as a response to the random access preamble.
