1. A method by a user equipment (UE) for controlling power in a communication system, the method comprising:
- identifying whether an uplink transmission and a sidelink transmission are allocated in a transmission time interval; and
transmitting, to another UE, the sidelink transmission in the TTI based on a transmission power, in case that no uplink transmission is allocated in the TTI; and
transmitting, to a base station, the uplink transmission in the TTI, in case that the uplink transmission and the sidelink transmission are allocated in the TTI,wherein the sidelink transmission is not transmitted to the another UE, in case that the uplink transmission and the sidelink transmission are allocated in the TTI.
