Determining method and device for macro and micro base station arrangement

The invention provides a determining method and device for macro and micro base station arrangement, and relates to the field of mobile communication. The networking manner between a macro base station and micro stations within the coverage range of the macro station is determined; and according to the determined networking manner, corresponding system spectrum-effect constraint and an edge user coverage constraint; a preset algorithm to determine the system efficacy, the emission power of the micro stations for determining the system efficacy and the amount of the micro stations which need arrangement are iterated till a parameter pair composed of the emission power and the amount of the micro stations is determined, and the system efficacy determined by the parameter pair is highest on the premise that the parameter pair satisfies the constraints, namely the emission power and the amount, of the micro stations, forming the parameter pair satisfy the system spectrum-effect constraint, and the amount of the m
