Method for performing, by terminal, transmission power control in wireless communication system, and terminal using method
A method of transmission power control performed by a user equipment (UE) in a wireless communication system, includes performing a wide area network (WAN) transmission in a first subframe of a WAN carrier; and performing a sidelink transmission in a second subframe of a sidelink carrier, wherein based on the first subframe and the second subframe overlapped in time, a lower bound of a maximum output power for the second subframe of the sidelink carrier is determined based on a maximum output power for the first subframe of the WAN carrier.
1. A method of transmission power control performed by a user equipment (UE) in a wireless communication system, the method comprising:
performing a wide area network (WAN) transmission in a first subframe of a WAN carrier; and
performing a sidelink transmission in a second subframe of a sidelink carrier,
wherein based on the first subframe and the second subframe overlapped in time, a lower bound of a maximum output power for the second subframe of the sidelink carrier is determined based on a maximum output power for the first subframe of the WAN carrier.
2. The method of claim 1 , wherein the first subframe is temporally earlier than the second subframe.
3. The method of claim 1 , wherein the first subframe is temporally later than the second subframe.
4. The method of claim 1 , wherein the WAN carrier and the sidelink carrier are different in a frequency domain.
5. A user equipment (UE) comprising:
a memory;
a transceiver; and
a processor, operably coupled to the memory and the transceiver, and configured to:
perform a wide area network (WAN) transmission in a first subframe of a WAN carrier, and
perform a sidelink transmission in a second subframe of a sidelink carrier,
wherein based on the first subframe and the second subframe overlapped in time, a lower bound of a maximum output power for the second subframe of the sidelink carrier is determined based on a maximum output power for the first subframe of the WAN carrier.
6. The UE of claim 5 , wherein the first subframe is temporally earlier than the second subframe.
7. The UE of claim 5 , wherein the first subframe is temporally later than the second subframe.
8. The UE of claim 5 , wherein the WAN carrier and the sidelink carrier are different in a frequency domain.
9. A processor for a wireless communication device in a wireless communication system,
wherein the processor is configured to control the wireless communication device to:
perform a wide area network (WAN) transmission in a first subframe of a WAN carrier, and
perform a sidelink transmission in a second subframe of a sidelink carrier,
wherein based on the first subframe and the second subframe overlapped in time, a lower bound of a maximum output power for the second subframe of the sidelink carrier is determined based on a maximum output power for the first subframe of the WAN carrier.
10. The processor of claim 9 , wherein the first subframe is temporally earlier than the second subframe.
11. The processor of claim 9 , wherein the first subframe is temporally later than the second subframe.
12. The processor of claim 9 , wherein the WAN carrier and the sidelink carrier are different in a frequency domain.
