Abstract:
Beamforming is used in wireless link communication to improve a wireless link through increased channel capacity and diversity by focusing a beam, such as from multiple antennas, in the direction of the receiver. Where the receiver may be capable of measurements relevant to beamforming, more particularly measurements that vary or are otherwise dependent upon changes in beamforming settings, reference to such measurements and corresponding beamforming settings may improve performance. In this Disclosure, a sink device transmits a data stream to a source device, wherein said data stream comprises the position of the sink device. The data stream may further comprise data such as link quality, heading information, or discretized location. The source device stores this data in a memory. When the wireless link deteriorates, the source device assesses its memory to select a candidate beamforming setting with some indicia of success, such as those that correspond closely to the sink device's position, the most recently used beamforming settings, or beamforming settings that previously resulted in a satisfactory wireless link quality.
