Abstract
A method of a network node of a radio access network is provided for detecting interference caused by intermodulation on a receive frequency of the network node. The method comprises determining at least one frequency of a signal which potentially gives rise to an intermodulation product on the receive frequency. The method comprises transmitting a request to a transceiver device, wherein the request includes information about the determined at least one frequency and an instruction to monitor that at least one frequency. The method comprises estimating interference level at the receive frequency at one or more time instants. The method comprises receiving a measurement report from the transceiver device, wherein the measurement report includes information about signal levels on the at least one frequency at one or more time instants. The method comprises determining whether the signal on the at least one frequency is probable to cause intermodulation interference on the receive frequency based on the estimated interference level at the receive frequency and the measurement report. Corresponding method of a transceiver device, a network node and computer programs for implementing the methods are also disclosed.
