Abstract:
1. A radio communication system comprising: a high-power base station; and a low-power base station installed in a communication area of the high-power base station and having lower transmission power than the high-power base station, wherein the radio communication system further comprising a division ratio determination unit configured to determine a resource division ratio of radio resources to be used as a particular downlink channel by the high-power base station, the resource division ratio being a ratio between first radio resources and second radio resources for which transmission power is limited to lower than that of the first radio resources, wherein the division radio determination unit determines the resource division ratio based on a traffic load of the low-power base station and a traffic load of the high-power base station such that: (1) the ratio between the second radio resources and the first radio resources is equal to a ratio between the traffic load of the low-power base station and the traffic load of the high-power base station; (2) with the traffic load of the high-power base station being constant, the higher the traffic load of the low-power base station, the more the second radio resources and the less the first radio resources; or (3) with the traffic load of the low-power base station being constant, the higher the traffic load of the high-power base station, the less the second resources and the more the first resources.
