Abstract
Methods and apparatus are provided for detecting interference between spectrally distinct wireless communication networks. A first base station in a first network communicates with a first mobile device at a first frequency, and a second base station communicates at a second frequency with a second mobile device geographically co-located with the first mobile device. The power level of an interfering signal received at the first base station from the second mobile device may be estimated by sharing information between the two networks through an interoperability gateway. The path loss of a reference signal transmitted from the first mobile device to its base station is communicated to the gateway, along with a parameter associated with the transmit power level of the interfering signal. Based on this parameter and the reference signal path loss, the received power level of the interfering signal may be inferred.
