Abstract
A method is provided for controlling the beam formation of downlink signals, which are emitted in a mobile radio communications system by base stations of a first and a second radio cell to a mobile station, whereby the base stations are configured to emit a weighted downlink signal to the mobile station, using a weighting vector. The method includes the steps of determination of a weighting vector record in the mobile station and the base stations of the first and second radio cell; selection of an optimal weighting vector in the mobile station and transmission of a code word that is assigned to the optimal weighting vector to the base stations; and weighted emission of the downlink signal to each base station using the weighted vector that has been assigned to the code word. In the base stations, the weighting vectors are assigned to the code words in various ways, so that upon receipt of an identical code word, the base stations weight the downlink signal using different weighting vectors.
