Abstract
PROBLEM TO BE SOLVED: To disclose power control for a device having a plurality of transmit antennas including power control methods for PUCCH (Physical Uplink Control Channel) and SRS (Sounding Reference Signal) transmission for a WTRU (wireless transmit/receive unit).
SOLUTION: PUCCH and SRS power control methods include selecting a MIMO (multiple input multiple output) mode and changing power of PUCCH or SRS transmission on the basis of the selected MIMO mode. Another power control method estimates an AGI (antenna gain imbalance) for a WTRU having at least two transmit antennas. The AGI is based on measuring RSRP (Reference Signal Received Power) on each transmit antenna. Each transmit antenna is then scaled by an AGI scaling factor based on the estimated AGI.
