Abstract:
An antenna array system incorporated in a base station of a cellular communication system comprisingat least a first antenna array; first beamforming means providing a plurality of beam ports, each beam port being associated with a directional beam of the first antenna array; a plurality of transceiver elements; switching means for associating the plurality of transceiver elements with the plurality of beam ports; and wherein the plurality of transceiver elements by the switching means are dynamically associated with the plurality of beam ports in response to a desired beam direction for radio communication supported by each of the plurality of transceiver elements and the association of transceiver elements to beam ports is rearranged at substantially periodic intervals, and wherein a first handover threshold associated with a first directional beam is different from a second handover threshold associated with a second directional beam.
