ABSTRACT:
A method and apparatus for communications resource allocation in a wireless communications system having a total system bandwidth. A service area is divided into a plurality sectors. A first set of base station antennas are positioned within a first set of sectors. The first set of antennas have main beams set at a first set of angles, and each antenna corresponds to a sector within the first set of sectors. A second set of base station antennas are positioned within a second set of sectors adjacent to the first set of sectors. The second set of antennas have main beams set at a second set of angles, and each antenna corresponds to a sector within the second set of sectors. Each sector is assigned a portion of the total system bandwidth.
