Abstract
Power control for devices having multiple transmit antennas are disclosed including power control methods for physical uplink control channel pucch and sounding reference signal srs transmissions for a wireless transmit/receive unit wtru (102a 102b 102c). The pucch and srs power control methods include selecting a multiple input multiple output mimo mode and changing the power of the pucch or srs transmission based on the selected mimo mode. Another power control method estimates an antenna gain imbalance agi for a wtru (102a 102b 102c) having at least two transmit antennas. The agi is based on measuring a reference signal received power rsrp on each transmit antenna. Each transmit antenna is then scaled by an agi scaling factor based on the estimated agi. The most illustrative drawing is fig. 2.
