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.
