Patent ID: 8693966

Claim:
A method for filtering out a wanted signal of a mobile station from a plurality of superimposed signals having a signal quality received by base stations in a cellular mobile network, wherein said superimposed signals are transmitted through a transmission resource, the method comprising the steps of: a) detecting said superimposed signal of said mobile station with a reached base station, b) determining a decodability of said wanted signal of said mobile station from said received superimposed signal at said reached base station, c) determining said signal quality of said received and superimposed signal for each reached base station, d) transmitting said signal quality to a decision device, e) selecting a base station for decoding and/or filtering out said wanted signals of said mobile station by means of said decision device, f) transmitting said received superimposed signal to said selected base station for decoding if said wanted signal cannot be fully decoded by said reached base station or transmitting said decoded wanted signal to said selected base station for filtering out said wanted signal if said wanted signal can be decoded by said reached base station, wherein said reached base stations transmit their received signals only to said selected base station for filtering out said wanted signal if said received signals support said filtering out said wanted signal in a digitized form, and wherein said selection of said selected base station is effected from one of said participating base stations which do not receive said directly decodable superimposed signal of said mobile station.
