  • Patent number: 11367358
    Abstract: A method of arranging platooning vehicles based on the vehicles' historic wireless performance. The method includes a requesting vehicle requesting permission from a lead vehicle of a platoon to join the platoon. The lead vehicle determines if the Advance Driver Assisted Systems (ADAS) Instance State-of-Health (SOH) Scores are above a predetermined minimal threshold and if so, then whether the Overall Historic ADAS SOH Score contains one or more discrepancies. If the Overall Historic ADAS SOH Score contains no discrepancies, the lead vehicle than analyzes the historic wireless performance data from the requesting vehicle and determines a historic wireless performance (WP) score for the requesting vehicle. The requesting vehicle is then arranged in the platoon based on the relative historic WP score of the requesting vehicle to the WP score of the platooning vehicles.

  • Publication number: 20220140874
    Abstract: A millimeter wave communication system for enhanced downlink beamforming and pairing is described. This includes a beamforming system for pairing with a mobile UE, using a base station with a MIMO antenna and a controller. The controller transmits first downlink beams from the MIMO antenna, including channel state information (CSI) reference signals. The mobile UE identifies a provisional downlink beam having a highest intensity CSI reference signal at the mobile UE. The controller receives a CSI reference signal resource indicator (CRI) feedback from the mobile UE that is responsive to the downlink beams and includes the provisional downlink beam, a present geographic position and trajectory of the mobile UE. A refined downlink beam is determined based upon the provisional downlink beam, the present geographic position, and trajectory of the mobile UE. The MIMO antenna transmits the refined downlink beam to execute a pairing with the mobile UE.
