Description

SIDELINK POSITIONING-BASED TRAFFIC CONTROL CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Patent Application No. 18/348,181, entitled, “SIDELINK POSITIONING-BASED TRAFFIC CONTROL,” filed on July 6. 2023, which is expressly incorporated by reference herein in its entirety. TECHNICAL FIELD [0002] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to sidelink positioning-based traffic control. Some features may enable and provide improved communications, including improved traffic control, a reduction in traffic accidents, or a combination thereof. INTRODUCTION [0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks may be multiple access networks that support communications for multiple users by sharing the available network resources. [0004] A wireless communication network may include several components. These components may include wireless communication devices, such as base stations (or node Bs) that may support communication for a number of user equipments (UEs). A UE may communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. [0005] A base station may transmit data and control information on a downlink to a UE or may receive data and control information on an uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighbor base stations or from other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighbor base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink. [0006] As the demand for mobile broadband access continues to increase, the possibilities of interference and congested networks grows with more UEs accessing the long-range wireless communication networks and more short-range wireless systems being deployed in communities. Research and development continue to advance wireless technologies not only to meet the growing demand for mobile broadband access, but to advance and enhance the user experience with mobile communications. [0007] A growing focus of research in wireless networks is the intersection of wireless communications and autonomous and semi-autonomous vehicles. Along with advances in autonomous vehicles, there is a push for improvements to traffic control devices and other roadside devices. One such example of a traffic control device is a freeway on- ramp light or sign, also referred to as a freeway on-ramp gating device, that displays a particular color or message when cars are permitted to enter the freeway from the on- ramp. In order to determine when cars may enter the freeway, the freeway on-ramp light may process sensor data to determine a congestion of the freeway in order for use in determining when cars may safely enter the freeway given current conditions. Typically, these sensors include three types of sensors: sensors underneath each freeway lane, sensors under each on-ramp lane near the freeway entrance, and sensors under each on- ramp lane near the connection to a feeder surface street. Installing and servicing these sensors can be an invasive process, requiring penetrating the road surface. Damage resulting from weather, seasonal temperature-induced expansion or contraction, or freeway widening all may require road excavation, introducing expense and impacting traffic along the freeway. Another example of a traffic control device is a stop light. In order to provide additionally functionality beyond time-based light control, a traffic light may include or be coupled to cameras or other sensors, such as sensors under a turn lane, that provide information used by the traffic light to change a displayed light or light cycle. Similar to the sensors of the freeway on-ramp light, the sensors and cameras of the traffic light may require time consuming and expensive processes to install or repair, such as excavating the road above the sensors, or the cameras and sensors may be susceptible to time or weather-based conditions, such as darkness, rain, or snow occluding the cameras. As such, typical traffic control devices are associated with significant costs and traffic disruptions to install and repair, and may lose some functionality due to weather or other external conditions, limiting the usefulness of such devices.
