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

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for determining uplink power in a wireless transmit receive unit (WTRU).SOLUTION: A 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 path loss of one of the plurality of uplink carriers and determine transmit power for the one of the plurality of uplink carriers on the basis of the plurality of power parameters, the transmit power control command, and the path loss.SELECTED DRAWING: Figure 8
