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).

1. A method implemented by an eNode-B, the method comprising:
transmitting, to a wireless transmit/receive unit (WTRU) via higher layer signaling, open loop uplink (UL) power control (PC) parameters including a cell-specific parameter and a WTRU-specific parameter; transmitting a PC correction command; and receiving, from the WTRU, a transmission having an applied transmit power, wherein:
the transmission comprises a number of resource blocks;the applied transmit power is based on a transmit power spectral density and the number of resource blocks;the transmit power spectral density comprises a combination of an open loop UL PC component, a closed loop PC component and a delta factor related to an offset value;the offset value is related to a modulation coding set (MCS);the open loop UL PC component is based on pathloss, the cell-specific parameter and the WTRU-specific parameter;the closed loop PC component includes a correction factor; andthe correction factor is based on the PC correction command.
