Title:

APPARATUS AND METHOD FOR UPLINK POWER CONTROL FOR A WIRELESS TRANSMITTER/RECEIVER UNIT UTILIZING MULTIPLE CARRIERS

Document Type and Number:

WIPO Patent Application WO/2010/091425

Kind Code:

A3

Abstract:

A method and apparatus for determining uplink power in a wireless transmit receive unit (WTRU). The WTRU operates in a carrier aggregated system. The WTRU is configured to receive a plurality of uplink power parameters indexed to one of a plurality of uplink carriers and receive a transmit power control command indexed to the one of the plurality of uplink carriers. The WTRU is configured to determine a pathloss of the one of the plurality of uplink carriers and determine a transmit power for the one of the plurality of uplink carriers based on the plurality of power parameters, the transmit power control command, and the pathloss.
