Abstract
The object is to implement autonomous and optimal cell formation on the occasion of adding a new resource to a cellular system. Abase station detects a location of its own, extracts location information about locations of neighbor base stations attached to broadcast signals from the neighbor base stations, captures the circumstances of the neighbor cell areas from these locations of its own and neighbor base stations, and sets a direction and a coverage (e.g., a cell radius and a spanning angle) of a new cell area on the basis of the circumstances of the neighbor cell areas. The base station may also be configured to capture the circumstances of the neighbor cell areas in consideration of propagation losses between the home station and the neighbor base stations, in addition to the above location information, or to capture the circumstances of the neighbor cell areas in consideration of the number of communicable base stations at a location of each mobile station in the neighborhood.
