Abstract

Provided is a joint pattern beam sectorization method and apparatuses for performing the same, wherein the joint pattern beam sectorization method including generating, in a service target region, a pattern sector corresponding to an antenna array including antennas having an identical radiation pattern by using the antenna array and generating pattern beam sectors in the pattern sector through a beamforming using the antennas.

Claims

1. A joint pattern beam sectorization method comprising:

generating, in a service target region, pattern sectors corresponding to pattern antenna arrays, each including pattern antennas by using the pattern antenna arrays; and

generating pattern beam sectors in each of the pattern sectors through a beamforming using the pattern antennas,

wherein each of the pattern antenna arrays has a different radiation pattern, at least one pattern beam sector included in a first pattern sector of the pattern sectors does not overlap with at least one pattern beam sector included in a second pattern sector of the pattern sectors, the first pattern sector is located adjacent to the second pattern sector, and the at least one pattern beam sector in the first pattern sector is located adjacent to the at least one pattern beam sector in the second pattern sector.

2. The method of claim 1, wherein the pattern antennas included in each of the pattern antenna arrays are disposed at a predetermined interval.

3. The method of claim 1, wherein the generating of the pattern beam sectors comprises generating output signals to be transmitted to the pattern beam sectors generated in each of the pattern sectors through a beamforming of input signals and transmitting the output signals to the pattern beam sectors generated in each of the pattern sectors using the pattern antennas included in each of the pattern antenna arrays.

4. A communication apparatus comprising:

pattern antenna arrays, each including pattern antennas; and

a beamformer to generate pattern beam sectors in pattern sectors corresponding to the pattern antenna arrays generated in a service target region through a beamforming using the pattern antennas,

wherein each of the pattern antenna arrays has a different radiation pattern, at least one pattern beam sector included in a first pattern sector of the pattern sectors does not overlap with at least one pattern beam included in a second pattern sector of the pattern sectors, the first pattern sector is located adjacent to the second pattern sector, and the at least one pattern beam sector in the first pattern sector is located adjacent to the at least one pattern beam sector in the second pattern sector.

5. The apparatus of claim 4, wherein the beamformer generates output signals to be transmitted to pattern beam sectors generated in each of the pattern sectors through a beamforming of input signals, and transmits the output signals to the pattern beam sectors generated in each of the pattern sectors using the pattern antennas included in each of the pattern antenna arrays.

6. The apparatus of claim 4, wherein the pattern antennas included in each of the pattern antenna arrays are disposed at a predetermined interval.
