Abstract
The present invention relates to a method for controlling uplink transmission power and to a wireless device using same in a wireless communication system. The wireless device receives determines uplink transmission power in consideration of the overlap period between subframes between a first serving cell belonging to a first timing advance (TA) group and a second serving cell belonging to the second TA group, and transmits an uplink channel on the basis of the uplink transmission power.

1-12. (canceled)
A method for controlling an uplink transmit power in a wireless communication system, the method comprising:
- determining, by a user equipment, a first maximum power reduction (MPR) for a first duration of a subframe considering a transmission on all of a plurality of serving cells;
- determining, by the user equipment, a second MPR for a second duration of the subframe considering a transmission on all of the plurality of serving cells;
- determining, by the user equipment, an uplink transmit power based on a maximum value of the first MPR and the second MPR;
- and
- transmitting, by the user equipment, uplink data using the determined uplink transmit power in the subframe.
A user equipment for controlling an uplink transmit power in a wireless communication system, the user equipment comprising:
- a radio frequency (RF) unit configured to transmit and receive a radio signal;
- and
- a processor operatively coupled to the RF unit and configured to:
- determine a first maximum power reduction (MPR) for a first duration of a subframe considering a transmission on all of a plurality of serving cells;
- determine a second MPR for a second duration of the subframe considering a transmission on all of the plurality of serving cells;
- determine an uplink transmit power based on a maximum value of the first MPR and the second MPR;
- and
- instruct the RF unit to transmit uplink data using the determined uplink transmit power in the subframe.
