Abstract:
1. A method in a cellular radio network in which at least a first User Equipment (UE 1 ) and a second User Equipment (UE 2 ) are operating, wherein UE 1 is in a first cell (Cell 1 ) served by a first base station and UE 2 is in a second cell (Cell 2 ) served by a second base station, wherein the method determines a level of severity of interference to UE 2 originating in Cell 1 , wherein the interference to UE 2 originating in Cell 1 is uplink interference caused by uplink transmissions from UE 1 , the method comprising the steps of: determining by an interference analysis tool, a first signal quality level experienced by UE determining by the interference analysis tool, a second signal quality level experienced by UE calculating by the interference analysis tool, a difference (Δ-measure) between the first and second signal quality levels for UE wherein the step of determining the first uplink SINR level experienced by UE where: P g P g I
