Abstract
A method and apparatus are disclosed comprising a combined open loop/closed loop uplink power control scheme for E-UTRA. The combined open and closed loop method for UL intra-cell PC controls the wireless transmit receive unit (WTRU) transmit power spectral density (PSD), PSDTX, (e.g. power per RB).
Claims38
A method for controlling transmit power of a wireless transmit receive unit (WTRU) comprising:
- determining an open loop uplink (UL) power control (PC) component based on pathloss measurement;
- determining a close 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.
1 more element
A wireless transmit receive unit (WTRU) comprising:
- a processor for determining an open loop uplink (UL) power control (PC) component based on pathloss measurement and a closed loop power control component including a correction factor wherein the open loop component and the closed loop component are combined with a power offset to determine a WTRU transmit power.
