Abstract
Interference may be detected in a cellular network by receiving signals at a target base station in a quiet resource block in which no uplink transmissions to the target base station are scheduled to occur, identifying a plurality of user equipment attached to base stations neighboring a target base station as interfering user equipment, reconstructing signals transmitted by the interfering user equipment, removing the reconstructed signals from the signals received by the target base station in the quiet resource block, and determining interference in the signals from which the reconstructed signals are removed. Detected interference data can be used to create an interference cancelling receiver.
