Method for interference reduction in a radio communication system, processing unit, and wireless access network node thereof

A processing unit for a first base station of a radio communication system to facilitate interference reduction in the radio communication system, the processing unit comprising:

• at least one processor, said at least one processor configured to:
• receive from at least one mobile station indications of radiation beams that are transmitted by the first base station of said radio communication system and that fulfill or exceed a predefined quality criterion, when said at least one mobile station is attached to said first base station and when said at least one mobile station is located within an overlapping coverage area of said first base station and of a second base station of said radio communication system,
• control whether said indications have been received at said first base station before or after a handover of said at least one mobile station from said first base station to said second base station or from said second base station to said first base station, and
• determine at least one radio resource to be unused or to be transmitted with a limited transmission power by said first base station for at least one radiation beam of said radiation beams based on said received indications for serving said at least one mobile station or at least one further mobile station by said second base station with said at least one radio resource,
• wherein the at least one radiation beam is taken into account by the at least one processor in conjunction with determining the at least one radio resource, if the received indication for the corresponding radiation beam was received before or after said handover.
