Abstract In a CDMA mobile telecommunications system with macro cells (C1) and micro cells (C2) the base station of the micro cells (C1) are designed in such a way that they are capable of arranging their reception area so that signals from any direction may be received in attenuated form. Interfering signals originating, in particular, from mobile stations (MS) outside micro cells (C2) are shielded in this manner. To generate null positions in the reception area of the micro cells, so-called null steering is used.
