A method for reducing interference between a first wireless network element, e.g. base station, eNodeB (210, figure 1) and a second, adjacent / neighbour, wireless network element, eNodeB (220) in a wireless communication system, comprises at the first wireless network element: receiving a downlink signal from the second wireless network element on a downlink channel associated with an uplink channel of the first wireless network element 605; and determining a signal quality level of the downlink signal from the second wireless network element. A coupling loss to the adjacent network element is calculated 610 using known transmit power values of the adjacent element 625. Interference power at the adjacent element is calculated 615 from the known transmit power of the first network element 630. The method further comprises determining an interference potential between the first wireless network element and the second wireless network element from the measurement 620; and adapting a network parameter associated with the uplink channel of the first wireless network element in response to determining the interference potential 640.
