The invention relates to a method for interference reduction in a radio communication system. The method (MET1) contains the steps of receiving (M1/6) at a processing unit (PU) from at least one mobile station (MS1) indications of radiation beams (B1, B2, B3, B4) that are transmitted by a first base station (BS1) of the radio communication system and that fulfill or exceed a predefined quality criterion at the at least one mobile station, when the at least one mobile station (MS1) is attached to the first base station (BS1) and when the at least one mobile station (MS1) is located within a first overlapping coverage area of the first base station (BS1) and of a second base station (BS2) of the radio communication system, and determining (M1/10) at the processing unit (PU) at least one radio resource to be unused or to be transmitted with a limited transmission power by the first base station (BS1) for at least one of the radiation beams (B1, B2, b3, B4) based on the received indications for serving the at least one mobile station (MS1) or at least one further mobile station (MS2) by the second base station (BS2) with the at least one radio resource. The invention further relates to a processing unit (PU) and to a wireless access network node, which contains the processing unit (PU).
