Abstract
Official abstract text for this publication.
A method is provided to reduce inter-cell interference in mobile wireless systems, and particularly in TDD wireless systems. In an embodiment, a base station receives a pilot signal from at least one of the mobile terminals that it serves at a plurality of base station antennas, which include both main antennas and auxiliary antennas. In response, each of the base station antennas provides an output that is processed to obtain a set of precoding weights for a transmission from the main antennas. The processing includes nulling at least one interfering signal using the outputs from at least the auxiliary antennas.
First claim
Opening claim text (preview).
What is claimed is: 1. A method performed by a base station serving one or more mobile terminals, comprising: receiving a plurality of signals at a plurality of base station antennas of the base station, said plurality of base station antennas including at least one main antenna and at least one passive antenna, said plurality of signals including at least one pilot signal from the one or more terminals and at least one interfering signal transmitted by a neighboring base station…
