    • An apparatus and method for controlling inter-cell interference comprising detecting and measuring uplink interference; and reporting the level of the uplink interference to an inter cell interference coordination (ICIC) server using a backhaul link. In one example, it may include receiving a measured uplink interference level through a first backhaul link; determining a transmit power level based on the measured uplink interference level; and sending through a second backhaul link the transmit power level for reconfiguring either a user equipment or a femtocell eNodeB. From the downlink perspective, it includes measuring a downlink interference; and reporting the level of the downlink interference to an ICIC server using a backhaul link. In one example, it may include receiving a measured downlink interference through a first backhaul link; determining a transmit power level based on the measured downlink interference; and sending a message comprising the transmit power level to a femtocell eNodeB using a second backhaul link.
    • 一种用于控制小区间干扰的装置和方法,包括检测和测量上行链路干扰; 并且使用回程链路将对上行链路干扰的级别报告给小区间干扰协调(ICIC)服务器。 在一个示例中,其可以包括通过第一回程链路接收测量的上行链路干扰电平; 基于所测量的上行链路干扰电平确定发射功率电平; 以及通过第二回程链路发送用于重新配置用户设备或毫微微蜂窝eNodeB的发射功率电平。 从下行链路的角度来看,它包括测量下行链路干扰; 并使用回程链路向ICIC服务器报告下行链路干扰的等级。 在一个示例中,其可以包括通过第一回程链路接收测量的下行链路干扰; 基于所测量的下行链路干扰确定发射功率电平; 以及使用第二回程链路向毫微微小区eNodeB发送包括所述发射功率电平的消息。
