    Abstract: Techniques described herein provide for enhanced ultra-local navigation services for V2X devices (e.g., smartphones incorporating V2X chip sets). The V2X devices can transmit vehicle information to edge network devices (e.g., roadside units). The roadside units can be deployed at intersections or along roads to collect traffic information through various sensor inputs and V2X communications with multiple vehicles. The communication between V2X devices and the edge network devices can be accomplished through wireless communication (e.g., direct PC5 interface or through local Uu interface with edge computing. The edge network devices can perform local route optimization and compute one or more recommendations (e.g., a recommend route, a recommended speed, a recommended lane). The edge network devices can transmit the one or more recommendations via a wireless communication to the V2X devices. The V2X devices can display the recommendations to a user.

    Abstract: Certain aspects of the present disclosure provide techniques for sensing window configuration for sidelink based ranging and positioning. For example, during sidelink-based ranging or sensing, a user equipment (UE) may determine the relative distance or position with other UEs. This may be realized by a UE broadcasting a wideband position reference signal (PRS) on an unlicensed band and measuring the round-trip time associated with a peer UE's PRS. The measurement accounts for a PRS transmission time transmitted by each UE. The UE may apply a sensing window to determine whether a neighboring UE has reserved PRS transmission times. The present disclosure provides methods and techniques for a network entity to configure a sensing window in a UE so that the UE may determine, during the sensing window, whether neighboring UEs have reserved a PRS transmission time.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless in-vehicle networking. A method that may be performed by a device in a vehicle includes wirelessly transmitting a data packet directly via a first device-to-device (D2D) communication link to another device in the vehicle; monitoring for an acknowledgment (ACK) of the data packet; deciding whether to retransmit the data packet to the other device, based on the monitoring; and wirelessly transmitting the data packet to a transmission relay, wherein an intended destination of the data packet is the other device, wherein the monitoring for the ACK comprises monitoring for a first ACK from the other device and a second ACK from the transmission relay.

    Abstract: An example method comprises obtaining information regarding a motion of a vehicle traversing the traffic intersection during a time window using video frames or image frames of the vehicle obtained by a traffic camera, obtaining roadway delineation information indicative of a traffic lane at the traffic intersection, wherein the roadway delineation information corresponds to the motion of the vehicle as indicated in the video frames or image frames of the vehicle obtained by the traffic camera, obtaining traffic light information of a traffic light at the traffic intersection, the traffic light information corresponding to the time window during which the vehicle traverses the traffic intersection, wherein the traffic light information indicates timing of the traffic light, and determining the traffic signal-to-lane association by using the information regarding the motion of the vehicle, the roadway delineation information, and the traffic light information to associate the traffic lane with the traffic light.
