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.
Claims12
A method for controlling an uplink transmit power in a wireless communication system, the method comprising:
- receiving, by a wireless device, a configuration regarding first and second timing advance (TA) groups from a base station;
- determining, by the wireless device, an uplink transmit power by considering an overlapping duration between subframes for a first serving cell belonging to the first TA group and a second serving cell belonging to the second TA group;
- and
- transmitting, by the wireless device, an uplink channel based on the uplink transmit power.
A wireless device for controlling an uplink transmit power in a wireless communication system, the wireless device 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:
- instruct the RF unit to receive a configuration regarding first and second timing advance (TA) groups from a base station;
- determine an uplink transmit power by considering an overlapping duration between subframes for a first serving cell belonging to the first TA group and a second serving cell belonging to the second TA group;
- and
- instruct the RF unit to transmit an uplink channel based on the uplink transmit power.
