Disclosed are a method and device for managing interference in a heterogeneous network. The method comprises: respectively determining the RSRQs of a base station and a low-power node; comparing the ratio of the RSRQ of the base station to the RSRQ of the low-power node with a preset threshold; and performing interference management on UE according to a comparison result. The present invention can significantly reduce interference among cells on the premise of guaranteeing the communication quality of the base station and the low-power node through resource allocation, power control and control channel configuration, guarantee the support to backward compatible/non-backward compatible UE through the setting of all the RE control channel information on a main/auxiliary carrier; implement new UE cell selection and handover policies through the reference values of the RSRQs of the base station and the low-power node so as to avoid the significant reduction of subsidiary (or service) UE of the low-power node; and solve the problem of interference among cells caused by that effective power control cannot be performed when the resource units of control channels are spread all over the whole system bandwidth in an RSRQ weighted manner. |
