1. A method of wireless communications by a victim base station (BS), comprising:
detecting interference from aggressor BSs;
transmitting distinguishable victim reference signals (RSs) to the aggressor BSs;
monitoring for distinguishable aggressor RSs from the aggressor BSs, each of the distinguishable aggressor RSs being transmitted in response to a corresponding one of the distinguishable victim RSs; and
determining to stop transmitting one or more of the distinguishable victim RSs based on the monitoring, wherein distinguishable victim RS transmissions to one of the aggressor BSs are stopped based on detection that distinguishable aggressor RS transmissions from the one of the aggressor BSs have stopped.
