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

User equipment and method for estimating an inter cell interference

A base band unit, BBU, in a wireless cellular heterogeneous network, the BBU being provided in a transmission node cluster, TNC, of transmission nodes, TNs, of neighboring cells of the wireless cellular heterogeneous network, wherein the BBU comprises generic hierarchical precoding codebooks, CBs, each CB comprising cluster precoding matrices, CPMs, and each CPM is provided for a possible combination of active TNs within the TNC.

Method and apparatus for providing generic hierarchical precoding codebooks
