Abstract

A control system connected to a plurality of array antenna performs beamforming. The control system comprises a beam radiation controller for requesting a predetermined first antenna group to radiate beams and requesting a second antenna group including the first antenna group to radiate beams to an optimized sector, a beam receiver for receiving response beams from the first antenna group and the second antenna group, and a sector selector for setting up an optimized sector based on the received beams for the first antenna group, and transmitting information on the optimized sector to the beam radiation controller in order to control the second antenna group to radiate beams to the optimized sector.

First claim

What is claimed is:

1. A control system for controlling beamforming by being connected to a plurality of array antennas, the control system comprising:
a beam radiation controller for requesting a predetermined first antenna group to radiate beams and requesting a second antenna group including the first antenna group to radiate beams to an optimized sector;
a beam receiver for receiving response beams from the first antenna group and the second antenna group; and
a sector selector for setting up an optimized sector based on the received beams for the first antenna group, and transmitting information on the optimized sector to the beam radiation controller in order to control the second antenna group to radiate beams to the optimized sector.

2. The control system of claim 1 , wherein the sector selector sets up a final sector based on response beams in response to a plurality of beams radiated to the setup optimized sector, and
sets up a sector radiating a response beam having a comparatively stronger intensity among the plurality of response beams as the optimized sector or the final sector.

3. The control system of claim 1 , wherein a number of antennas included in the second antenna group is decided as multiple of 2n of the first antenna group.
