In a radio communication system in which a micro cell is provided in a macro cell, when a user terminal that is connected to the macro base station is located in the micro cell, interference signals which the user terminal receives from the micro base station are reduced. With the interference reduction method of the present invention, a user terminal UE that is connected to a macro base station (eNB) forming a macro cell transmits interference information indicating the interference signal power which the user terminal (UE) receives from a micro base station (HeNB) forming a micro cell, to the macro base station (eNB), when the interference signal power indicated by the interference information meets a predetermined condition, the macro base station (eNB) reports that to the micro base station (HeNB), and, in response to the report from the macro base station (eNB), the micro base station (HeNB) transmits data using a transmission frame in which interference signals from the micro base station (HeNB) at the user terminal (UE) can be reduced.
An interference reduction method in a radio communication system in which a micro cell is provided in a macro cell, the method comprising:
A radio base station forming a micro cell in a radio system in which the micro cell is provided in a macro cell, the radio base station comprising a data transmission section that, when a report is received, from a macro base station, which is a radio base station forming the macro cell, that interference signal power which a user terminal that is connected to the macro base station receives meets a predetermined condition, transmits data using a transmission frame in which interference signals from the radio base station at the user terminal can be reduced.
A radio base station forming a macro cell in a radio system in which a micro cell is provided in the macro cell, the radio base station comprising:
