Abstract(in Japanese) (See Japanese page)
Abstract(in English) A spectrum sharing method has been proposed for wireless communication systems with different priorities and the theoretical capacities achieved by low-priority systems were given. However the effectiveness of the method has not been studied under mutli cell environments, since the analysis assumed a hotspot environment. In this paper, we give the achievable capacity of this method under multicell environments, where neighboring base stations are assumed to operate using the spectrum sharing method. Numerical results show that the proposed method can attain almost double the capacity achieved by a spectrum sharing method with constant transmit power.
