  • Patent number: 11375386
    Abstract: A method for beamform management in vehicular communications includes, within a computerized processor, determining a planned route for a vehicle, identifying a plurality of candidate cellular towers with which the vehicle may communicate along the planned route, and determining signal strengths of each of the towers at locations along the route. The method further includes determining a communication plan including identifying locations of each of the towers and segmenting the planned route into portions based upon the determined signal strengths. One of the towers is assigned to communicate with the vehicle for each of the portions based upon the signal strengths. The method further includes utilizing the communication plan to change communication between the vehicle and the towers as the vehicle traverses the route by directing a primary lobe of an antenna beam toward each of the candidate cellular towers in turn according to the communication plan.

  • 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.

    Abstract: A mobile communication system of a motor vehicle includes a primary antenna. The system further includes a telematics module having a processor and at least one memory including a computer program code. The memory and the computer program code are configured to, with the processor, cause the system to detect a predetermined vehicle event and measure a primary signal quality of the reference signal received at the primary antenna. The memory and the computer program code are configured to, with the processor, cause the system to determine a maximum primary signal quality and compare the maximum primary signal quality with a threshold. The memory and the computer program code are configured to, with the processor, cause the system to determine a defect in the primary antenna and activate a diagnostic trouble code associated with the defect, in response to determining that the primary maximum signal quality is below the threshold.
