Radio communication system, centralized station, control station apparatus, radio base station and coordinated transmission method for determining an assignment of cluster patterns

摘要

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.
