Interference suppression method, the macro base station, micro base station system and

Embodiment of the present invention provides a method for suppressing interference, the macro base station, micro base station and the system. A method comprising: obtaining resident micro base station of the serving cell and in the channel parameters of the UE in CELL-DCH state or a CELL_FACH state; based on the channel parameter, the uplink channel of each UE is listening to obtain an uplink interference amount to the macro base station UE ; according to the uplink interference amount, determined from the UE to the target UE transmit power to be reduced; target UE will inform the micro base station, micro base station to decrease the transmission power of the target UE. Aspect of the present invention can reduce interference to the micro-cell base station is located in a serving cell of the UE and reduce the waste of the macro base station uplink resource.
