摘要： A first radio base station (1A) calculates a traffic amount ratio in the first radio base station (1A). Further, when the traffic amount ratio is equal to or greater than a threshold value, the first radio base station (1A) controls to transmit interference information. Under this control, the first radio base station (1A) performs a measurement of interference power, a generation of the interference information and the transmission of the interference information to a second radio base station (1B). On the other hand, when the traffic amount ratio is less than the threshold value, the first radio base station (1A) controls to halt the transmission of the interference information. Under this control, the first radio base station (1A) performs none of the measurement of interference power, the generation of the interference information and the transmission of the interference information to the second radio base station (1B).
