    • A cellular radio communication system includes a first mobile terminal, a base station that performs radio communication with first mobile terminals, a second mobile terminal, and a second base station that performs radio communication with second mobile terminals. In the downlink communication, the base station selects a high data rate mode when the radio interference from the base station to the second mobile terminals that are located close to an edge of a communication area of the second base station is small. The base station selects an interference mitigation mode in the downlink communication when the radio interference from the base station to the second mobile terminals that are located close to the edge of the communication area of the second base station is large. Thus, inter-cell interference control can be performed in collaboration with base stations in the radio communication system without having communication interface between the base stations.
    • 蜂窝无线电通信系统包括第一移动终端,与第一移动终端进行无线通信的基站,第二移动终端以及与第二移动终端进行无线通信的第二基站。 在下行链路通信中,当从基站到位于第二基站的通信区域的边缘附近的第二移动终端的无线电干扰小时,基站选择高数据速率模式。 当基站到位于第二基站的通信区域的边缘附近的第二移动终端的无线电干扰较大时,基站选择下行链路通信中的干扰减轻模式。 因此,可以与无线通信系统中的基站协作地执行小区间干扰控制,而不需要基站之间的通信接口。
