Abstract: A system of managing communications in a vehicle includes a telematics unit connected to the vehicle. The telematics unit is configured to execute a retransmission request protocol upon receipt of erroneous data. A command unit in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is adapted to determine vehicle situational parameters at a beginning of a data communication cycle. The vehicle situational parameters including current location and navigation status of the vehicle. When a first retransmission according to the retransmission request protocol is detected, the vehicle situational parameters are updated. The command unit is adapted to determine a desirable value of a retransmission frequency for the retransmission request protocol based in part on the updated vehicle situational parameters. In one embodiment, the retransmission request protocol is Hybrid Automatic Repeat Request (HARQ).

Abstract: A system for managing communication between a vehicle and a broker module includes a telematics unit connected to the vehicle. The telematics unit is configured to carry out wireless data communications according to a publish-subscribe messaging protocol. A command unit is in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The telematics unit is configured to establish a network connection with the broker module. The command unit is adapted to create a dynamic retry delay process for the network connection by varying a connection retry delay time based on a plurality of failure categories and an operation mode of the vehicle. The plurality of failure categories each corresponds to a respective failure in the network connection.

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 system for updating vehicle time information includes a communication device configured to wirelessly communicate with a wireless network using a network communication protocol. The system also includes a processing unit configured to assess communications between the vehicle to determine whether a condition related to a potential local time offset error exists, and based on determining that the condition exists, transmit a message supported by the communication protocol to the wireless network. The message is configured to prompt the wireless network to return a response message including a local time offset. The process is also configured to update a vehicle local time record based on the local time offset.

Abstract: Multimode messaging of the type suitable for use in communicating a plurality of datasets to a vehicle, a telematics unit, and/or another device. The multimode message may be facilitated with a hybrid platform having a plurality of radio access points configured for supporting messaging with a vehicle according to differing types of wireless radio communications and a back office controller configured for determining multimode information to be added to each of the datasets prior to the datasets being communicated to the hybrid platform for transport to the vehicle.

Abstract: Presented are intelligent vehicle communications (comm) systems provisioning enhanced vehicle-to-everything (V2X) wireless mesh network (WMN) hop propagation, methods for making/using such systems, and vehicles equipped with such systems. A method of controlling operation of a host vehicle includes a vehicle controller determining the host vehicle is incapacitated and then detecting the host vehicle's wireless comm device is unable to connect to a cellular or satellite communications system. Responsive to such insufficient connectivity, the controller broadcasts a V2X WMN distress message containing data specific to the host vehicle and data specific to the host vehicle's incapacitating event. Upon receipt of the distress message, a recipient vehicle's controller determines if a prior distress message for the incapacitating vehicle event was previously received and if the distress message exceeds any preset multi-hop restrictions. If yes to either, the resident controller disables retransmission of the distress message to other recipient nodes over the WMN.

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.
