15. A wireless transmit/receive unit (WTRU) comprising circuitry, including any of a transmitter, a receiver, a processor and a memory, the WTRU being configured to:
transmit to a base station information indicating existence of a sounding reference signal (SRS) power imbalance for at least one transmit and receive (xTyR) antenna configuration in a set of xTyR antenna configurations;
receive from the base station a request to report SRS power imbalance information; and
transmit to the base station the SRS power imbalance information indicating, for at least one SRS resource set associated with the at least one xTyR antenna configuration, (i) one or more impacted SRS resources in the at least one SRS resource set and (ii) one or more power imbalance values for the one or more impacted SRS resources.
