Abstract
Systems and methods which implement cooperative random or quasi-random beam forming as between a plurality of base stations in a wireless network to reduce multi-cell interference are shown. For example, a plurality of base stations in a wireless network cooperate to provide frequency resources, such as channels, subchannels, subcarriers, etc., in a plurality of randomesque beams. In operation, subscriber stations preferably analyze signals as received on a plurality of the randomesque beams to determine one or more 'best' beams for use in communication between the subscriber station and base station. Assuming an identified beam is available for use by the subscriber station, payload communications may be provided using one or more beams identified by the subscriber station as a 'best' beam. The base stations of the wireless network preferably cooperate to periodically reform the randomesque beams.
