Managing sounding reference signal symbol transmit power imbalance

Abstract

Various aspects of the present disclosure relate to an apparatus for managing SRS symbol imbalance. For instance, techniques are described for correcting sounding reference signal (SRS) based uplink and downlink channels when a UE compensates for SRS power relaxations at power levels below a maximum configured power. With the assistance of the UE, for example, a gNB can validate SRS power relaxations reported by the UE. Further, if the measured relaxations are different than the power relaxations reported by the UE, the gNB can apply corresponding corrections to the SRS based channel estimates. In at least some scenarios, the UE may allow compensation of the SRS power relaxations which can be enabled and disabled under the control of the gNB and compensation of the SRS power relaxations may be addressed by adding SRS port-based offsets to an SRS power control equation.
