Determining an estimated location of a source of interference

Abstract

Location of a source of interference 106 is estimated. The interference affecting a plurality of base stations 102a, 102b of a cellular radio communication system providing coverage in a geographical area. The method includes, for first and second base stations 102a at different first X1, Y1 and second X2, Y2 locations, determining estimated respective first and second angles of arrival for the interference source at the first and second base station based on a determined difference between a received signal strength (RSS) of the interference source for first and second antennas of each base station. The method further includes determining, based on the estimated first and second angles of arrival at the respective first and second locations, an estimated location of the interference source in the geographical area. Correlation may be used to identify groups of interfered cells based on power spectral density (PSD) in received carrier signals across different frequency bands over time intervals.
