Abstract
Methods and apparatuses are provided for controlling power in a communication system. It is identified whether there is uplink transmission from a first UE. Sidelink transmission is transmitted from the first UE to a second UE based on a transmission power, if there is no uplink transmission from the first UE.
Claims12
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.

A user equipment (UE) in a communication system, comprising:
- a transceiver configured to transmit and receive signals;
- and
- a controller configured to:
- identify whether an uplink transmission and a sidelink transmission are allocated in a transmission time interval,
- transmit, 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
- transmit, 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.
