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 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 closed loop PC component including a correction factor, wherein the correction factor is based on a PC correction command signaled in a UL grant associated with a hybrid automatic repeat request (HARQ) process; combining the open loop component and the closed loop PC component with a delta factor related to an offset value to determine a transmit power, wherein the offset value is related to a modulation coding set (MCS); and applying the transmit power in accordance with a timing of the HARQ process.
