<p>A femto cell base station and a method are disclosed. The method comprises the steps of: a) monitoring data transmission antenna weights used during wireless data transmissions over a femto cell data channel between a femto cell base station and user equipment; b) deriving broadcast channel antenna weights from the data transmission antenna weights; and c) forming the femto cell broadcast channel beam using the broadcast channel antenna weights. The femto cell broadcast channel beam is adapted to minimise interference. The femto cell broadcast channel beam may then be formed using those broadcast channel antenna weights in order to direct and restrict the size of the broadcast channel beam and reduce the likely interference caused by the femto cell to other femto cells and to a macro cell.</p> |
