Partitioning a coordination area in a wireless network

摘要

The present invention relates to a wireless network, and more specifically, to a method and apparatus for partitioning a coordination area in a wireless network, the method comprising: obtaining antenna directions of respective cells, base station locations of respective cells, and scope of a coordination area within the wireless network; determining an initial coordination area based on the scope of the coordination area and the base station locations in respective cells; partitioning the initial coordination area into an inner area and an outer area; partitioning the outer area into an inward area and an outward area based on the antenna directions of cells within the outer area and the base station locations of cells within the outer area; and combining the inner area and the inward area within the outer area into a new coordination area. The method is simple and easy. It may solve a problem of coordination area edge caused by partitioning a coordination area and meanwhile avoid the association between coordination areas, thereby reducing the complexity of scheduling.

1. A computer-implemented method for partitioning a coordination area in a wireless network, the method comprising:
obtaining an antenna direction for each of a plurality of respective cells, a base station location for each of the plurality of respective cells, and a scope of a coordination area within the wireless network; determining an initial coordination area based on the scope of the coordination area and the base station location in each of the plurality of respective cells; partitioning the initial coordination area into an inner area and an outer area; partitioning the outer area into an inward area and an outward area based on a plurality of antenna directions of the plurality of respective cells within the outer area and a plurality of base station locations of the plurality of respective cells within the outer area; and combining the inner area and the inward area within the outer area into a new coordination area, wherein the step of partitioning the outer area into an inward area and an outward area based on the plurality of antenna directions of the plurality of respective cells within the outer area and the plurality of base station locations of the plurality of respective cells within the outer area comprises: making a connection line between a base station location of a cell within the outer area as a start point and a center of the initial coordination area as an end point, wherein: if an angle between the connection line and a direction of an antenna of the cell within the outer area is acute, the area governed by the antenna of the cell belongs to the inward area; and if the angle between the connection line and the direction of the antenna of the cell within the outer area is right or obtuse, the area governed by the antenna of the cell belongs to the outward area.
