Abstract

A method detects a first baseband signal sent by a first sending station via an air interface to a first radio station of a radio communications system. A first receive signal, which contains the first baseband signal superposed with at least a second baseband signal sent by a second sending station to a second radio station, is received by the first radio station. The first radio station uses at least a second receive signal received by the second radio station for detection of the first baseband signal. The second receive signal contains at least the second baseband signal, and is used to at least partially cancel the interference in the first receive signal caused by the second baseband signal.
