Abstract (en)

[origin: WO0059072A1] A beamforming method and device for adaptive antenna arrays containing several antenna elements (1.1 - 1.M) in a frequency duplex system downlink, whereby the antenna weights (Wk(fS)) are determined for the antenna elements (1.1 - 1.M.) for downlink transmission on the basis of directional information pertaining to the uplink; the antenna weights (Wk(fS)) are individually determined for downlink transmission on the basis of the power-angle spectrum (APSk) of the uplink of individual users (B1 - BK), whereby the power-angle spectrum (APSk) is modified by blocking out undesirable areas.
