The invention relates to a method for determining interference in multiple antennae systems comprising adaptive antennae in the downlink. To this end, respective fractions of emission powers of corresponding master stations and of other master stations, which are provided for other subscribers and are received by the respective subscribers as an interference power, are added up on the basis of beam formation variables for determining interference, for possible subscribers (23, 24, 25, 26) in coverage areas of master stations (20, 21, 22). The fractions (e.g. 20.23') multiplied by a reduction factor (a) and received by the subscriber (e.g. 24) concerned, of emission powers (e.g. 20.23) emitted by the respective corresponding master station (e.g. 20) in the coverage area concerned, for subscribers other (e.g. 23) than the respective subscriber concerned (e.g. 24), are viewed as an interference power. As additional interference sources, at least the control information (Ilntra) emitted by the respective corresponding master station (20) into the coverage area concerned, and the control information (I=nter) emitted by the other master stations (21, 22) into the coverage area, are determined as a fraction of interference power. |
