Abstract

Certain aspects of the present disclosure provide methods and apparatus for sounding reference signal (SRS) triggering and power control for coordinated multi point (CoMP) operations. One method generally includes maintaining separate power control processes for at least a first aperiodic SRS (A SRS) and a second A SRS receiving in a first subframe a downlink transmission triggering transmission of at least one of the first and second A SRS in a subsequent subframe identifying which of the first and second A SRS to transmit in the subsequent subframe receiving a first power control command that indicates a power control value to apply to the identified A SRS and transmitting the identified A SRS based in accordance with the first power control command.
