Abstract
A radio communications system has subscriber stations and a base station that is provided with an antenna system with a plurality of antenna elements that emit a downlink signal in a weighted manner with coefficients of a weighting vector. In order to form a beam, a plurality of weighting vectors is determined at the subscriber station and the determined weighting vectors are transmitted to the base station. In a subsequent working phase, the subscriber station selects a dominant vector among the determined weighting vectors and transmits an indicator of the selected weighting vector to the base station.
