Claim One:
1. A method of coordinated beamforming performed at a central controller in a network having a plurality of mobile stations and a plurality of base stations, the method comprising: requesting, by the central controller, a selected mobile station (MS) to measure a link quality of a wireless link between the selected MS and each base station (BS) of the plurality of BSs; receiving, from the selected MS, channel estimation information for wireless links of a selected subset of the wireless links that meet one or more specified criteria; determining, by the central controller, a transmit beamforming vector for each BS associated with the wireless links of the selected subset and a receive combining vector for each of the wireless links of the selected subset, based on the channel estimation information; providing, by the central controller, the receive combining vector to each MS of each BS associated with the wireless links of the selected subset; and transmitting the transmit beamforming vector to each BS associated with the wireless links of the selected subset.
