Abstract

A beamforming method including selecting a first transmission site from a plurality of transmission sites (108a, 108b, 108c) based on the quality of a first channel between the first transmission site and an endpoint or terminal (110). The method further includes determining a first precoding matrix corresponding to the first transmission site. The first precoding matrix may be applied to data transmitted by the first transmission site to the endpoint. The method further includes determining a second precoding matrix corresponding to a second transmission site of the plurality of transmission sites. The second precoding matrix may be determined based on at least a first spatial direction that is calculated based on at least the first channel.
