Abstract
In a CDMA mobile telecommunications system with macro cells (C ) and micro cells (C ) the base station of the micro cells (C ) 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 [sic]. Interfering signals originating, in particular, from mobile stations (MS) outside micro cells (C ) are shielded in this manner. To generate null positions in the reception area of the micro cells, so-called null steering is used.
