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.
