Abstract
An electronically phase-controlled group antenna is calibrated in radio communications systems, using a reference point shared by all the reference signals. In the downlink, reference signals which can be distinguished from one another are simultaneously transmitted by individual antenna elements of the group antenna and are suitably separated after reception at the shared reference point.
