First Claim
Patent Images
1. A method for controlling transmit power of a wireless transmit receive unit (WTRU) comprising:
- determining an open loop power control component based on a pathloss measurement;
determining a closed loop power control component including a correction factor; and
combining the open loop component and the closed loop component with a power offset to determine a transmit power.
