Abstract

A user equipment, UE (4), registered with an anchor cell base station (3-0) of an anchor cell (2-0) of a cellular wireless network (1), the UE (4) comprising a determination unit being adapted to predict an inter cell interference, ICI, at the UE (4), caused by base stations (3-1 to 3-6) of neighboring cells (2-1 to 2-6), depending on precoding matrix indicators, PMIs, of precoding matrices, PMs, the PMIs being exchanged between the anchor cell base station (3-0) of the anchor cell (2-0) and the base stations (3-1 to 3-6) of the neighboring cells (2-1 to 2-6).
