Abstract: Various embodiments include methods that may be implementing in a computing system within vehicles for supporting communicating proxy basic safety communications while operating within a platoon of vehicles to control congestion on frequencies used for basic safety communications. In various embodiments, while a vehicle is operating as a designated platoon vehicle, the computing system may generate a proxy basic safety communication including position and dimension information of the platoon as a whole, and broadcast the proxy basic safety communication on behalf of vehicles in the platoon. The proxy basic safety communication may include positions of certain vehicles within and dimensions of the platoon. While in a platoon but not operating as the designated platoon vehicle, the computing system may not broadcast basic safety communications or broadcast such communications at low power.

Abstract: Techniques are discussed herein for transmission of location information by a user equipment (UE) to other UEs. A UE receives Satellite Positioning System (SPS) signals and determines whether the SPS signals are reliable. The UE determines a location estimate to be transmitted to other UEs using the SPS signals if the SPS signals are determined to be reliable and using non-SPS information if the SPS signals are determined to be not reliable. The location information is transmitted to other UEs in a message that includes an indication of the source of information used to generate the location estimate. A UE that receives the message may determine its location estimate based, at least in part, on the indication of the source of information, e.g., by determining whether SPS signals are reliable based, at least in part, on the indication of the source of information received in the message.

Abstract: Techniques are discussed herein for detecting anomalous signals such as spoofed satellite positioning system (SPS) signals and for the transmission of accurate location estimates between user equipments (UEs) when the SPS signals are not reliable. A UE determines an SPS derived location estimate and determines an associated confidence level. The confidence level is determined based on time or location derived from the SPS signals, e.g., relative to local time or non-SPS information, such as stored previous location estimates, non-SPS sensor information, and location information from other UEs. The UE transmits location information to other UEs that includes a selected location estimate, confidence level, and the source of the location estimate, e.g., where the SPS derived location estimate is selected if the confidence level is high and the non-SPS derived location estimate is selected if the confidence level is low.

Abstract: The calibration of a vehicle sensor can be conducted based on communication between vehicles. A first vehicle needing sensor calibration can receive calibration information from a second vehicle, indicating the location of a calibration marker at one or more times. The first vehicle can then compare the calibration information with measurement information of the calibration marker made by a sensor, and recalibrate the sensor based on a comparison of the calibration information and measurement information. According to some embodiments, vehicles may leverage existing vehicle-to-vehicle communications (e.g., Cellular vehicle-to-everything (V2X) communication) to broadcast calibration capabilities.
