Steer: Beam Selection for Full-Duplex Millimeter Wave Communication Systems

Modern millimeter wave (mmWave) communication systems rely on beam alignment to deliver sufficient beamforming gain close the link between devices. We present a novel selection methodology for multi-panel, full-duplex mmWave systems, which we call Steer, that delivers high while significantly reducing self-interference coupled transmit and receive beams. Steer does not necessitate changes conventional methodologies nor additional over-the-air feedback, making it compatible with existing cellular standards. Instead, uses identify general directions beams should be steered, then makes use of minimal number measurements jointly select in these coupling low self-interference. implement an industry-grade 28 GHz phased array platform further simulation show operation selected by can notably outperform both half-duplex chosen via selection. For instance, reliably reduce more than 20 dB improve SINR 10 dB, compared Our experimental results highlight used only but also mitigate levels near or below noise floor, rendering cancellation unnecessary Steer.
