Abstract: The present disclosure relates to notifying a terminal of subcarrier spacing(s) used in a random access procedure. A master information block (MIB) includes information associated with a first subcarrier spacing used for a system information block (SIB) and a random access response. The SIB includes information associated with a second subcarrier spacing used for a physical random access channel (PRACH) on which a random access preamble is transmitted. A terminal transmits the random access preamble to a base station based on the second subcarrier spacing and receives, from the base station, a random access response to the random access preamble based on the first subcarrier spacing.
