1. A method for interference handling, the method being performed by a network node, the method comprising:
obtaining an indication of interference in a time/frequency interval;
querying a neighbouring network node about scheduling in the time/frequency interval of uplink wireless transmission from any terminal device served by the neighbouring network node; and
receiving a response from the neighbouring network node, the response comprising information identifying uplink reference signal resources/ports, and their scheduling, as to be used by the terminal device scheduled in the time/frequency interval.
