Abstract
The radio communication system of the present invention is provided with a cluster pattern determining section that determines the assignment of each cluster pattern to each cluster so as to suppress inter-cluster interference with other neighboring clusters less than or equal to a predetermined value, the cluster pattern is defining a directional pattern of which directional beams emitted from the respective radio base stations face each other for each identical frequency block between neighboring sectors in a cluster composed of neighboring cells, the each cluster pattern being in different combinations of directional patterns and frequency blocks.
