COMBINED OPEN LOOP/CLOSED LOOP METHOD FOR CONTROLLING UPLINK POWER OF A MOBILE STATION

摘要

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).

主权项

1. A method implemented in a wireless transmit receive unit (WTRU), the method comprising:
receiving signaling indicating an uplink (UL) resource assignment, a power control (PC) correction command and an assigned modulation coding set (MCS); and applying a transmit power to an UL transmission, wherein the transmit power is based on a combination of a bandwidth of the UL resource assignment, an open loop PC component, a closed loop PC component and a delta factor related to an offset value, wherein:
the open loop PC component is based on pathloss and open loop PC parameters;the closed loop PC component includes a correction factor;the correction factor is based on the PC correction command; andthe offset value is related to the assigned MCS.
