Abstract

In mobile communications system of the CDMA type in particular detection of individual signals from the received common signal with known methods requires much processing capacity of the mobile communications system. The present invention concerns a method of reducing radio interference in a mobile communication system including at least one base station (BS) and several mobile stations (MS). The mobile communications system uses several traffic channels for communications between the base station (BS) and the mobile stations (MS). The method according to the invention is characterized in that signals received at the same reception point are classified therein into at least two classes according to the interference tolerance of the signal or according to the interference caused by the signal to other signals and/or according to the complexity of decoding of the signal, a special way of functioning is defined for each class, whereby the total interference caused by received signals to one another is reduced by complying with these ways of functioning, and the individual signals of each class are processed at the point of reception in the way of functioning defined for the class in question.
