摘要：
Methods and apparatus for sounding reference signal (SRS) power control for a wireless transmitter/receiver unit (WTRU) are disclosed. These methods and apparatus include methods and apparatus for carrier-specific and carrier-common SRS power control in WTRUs that utilize carrier aggregation techniques. These methods and apparatus also include methods and apparatus for SRS power control in WTRUs utilizing both carrier aggregation and time division multiplexing (TDM) techniques. Additionally, these methods and apparatus include methods and apparatus for SRS power control for WTRUs utilizing multiple input multiple output MIMO operation. Methods and apparatus for SRS overhead reduction and power management in a WTRU are also disclosed.
