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

摘要

PROBLEM TO BE SOLVED: To provide a method of transmit power control better than several existing intra-cell transmit power control schemes for the UL E-UTRA, which can be generally classified into slow open loop PC and slow closed loop (or CQI-based) PC, the slow closed loop or CQI-based PC degrading performance when there is no available feedback because of UL transmission pauses or feedback transmission pauses.

SOLUTION: A method and apparatus is 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).
