Abstract
A control system connected to a plurality of array antenna performs beamforming. In order to perform the beamforming, the control system receives response beams inputting to a first antenna group predetermined from a plurality of array antenna in response to radiate beams and decides a sector having comparatively stronger intensity. And the control system receives response beams inputting to a second antenna group, decides a plurality of beam levels and decides a final beam pair among the plurality of the decided beam levels.
Claims4
A method for beamforming at a control system connected to a plurality of array antennas, the method comprising:
- requesting a first antenna group to radiate beams to a plurality of predetermined sectors, wherein the first antenna group is predetermined from the plurality of array antennas;
- receiving response beams inputted to the first antenna group in response to the radiated beams;
- selecting, from the plurality of predetermined sectors, a sector related to a response beam having a comparatively stronger intensity among the received response beams inputted to the first antenna group;
- setting up a second antenna group including the first antenna group and a plurality of antennas adjacent to the first antenna group as a second antenna group;
- requesting the second antenna group to radiate beams to a plurality of sub sectors in the selected sector;
- receiving response beams inputted to the second antenna group in response to the radiated beams of the second antenna group;
- selecting, from the plurality of sub sectors, a sub sector related to a response beam having a comparatively stronger intensity among the received response beams inputted to the second antenna group;
- deciding a plurality of beam levels through by beam level training with the selected sub sector;
- and
- deciding a final beam signal pair from the plurality of beam levels by high resolution (HRS) beam training with the selected sub sector.
