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.

Abstract: Methods and apparatuses are provided in which at least one parameter associated with a sidelink transmission is received from a base station. It is identified whether an uplink transmission is scheduled in a transmission time interval (TTI) in which a sidelink transmission to a second terminal is scheduled. The sidelink transmission is transmitted to the second terminal in the TTI in case that no uplink transmission is scheduled in the TTI. The sidelink transmission is transmitted based on a smaller transmission power value from two transmission power values.
