Methods and apparatus for beamforming for femtocells
Abstract:
Methods and apparatus for beamforming for femtocells, such as in LTE wireless networks, to provide inter-cell coordination and interference mitigation are disclosed. A macrocell user equipment (UE) may determine information regarding an interfering femtocell node, such as a home eNodeB (HeNB). The information may be sent directly or indirectly, such as by a backhaul communication link, to the HeNB. The HeNB may adjust an output based on the information. The information may include spatial channel information, which may be used for beamforming at the HeNB output so as to mitigate interference in the direction of the UE.
