Abstract
The present invention provides a method for suppressing interference using beamforming of uplink signals received at multiple base stations. The method may include accessing information indicative of a plurality of signals received over a plurality of uplink channels between a plurality of mobile units and a plurality of base stations. The method may also include forming a plurality of weighted signals by applying a plurality of beamforming weights to the plurality of signals. The plurality of beamforming weights are determined based on estimates of the channels from the plurality of users to the plurality of base stations and estimated interference between the signals. The method may further include combining subsets of the plurality of weighted signals associated with each of the plurality of mobile units.
