Millimeter-wave communication between vehicles, and between vehicles and infrastructure, called vehicle-to-everything (V2X), can exchange not only compressed sensing data like speed and lane changes, but also high-bandwidth content like video and other data-intensive information. This enables more detailed and robust processing of information and thus helps to further reduce accidents and traffic congestion. Design of mmWave V2X systems requires knowledge of the propagation channels that such systems encounter. This invited paper surveys a series of vehicular channel measurement campaigns that a team of four research institutions has performed over the past seven years in Europe and the US. The paper describes the design of the measurement setup, as well as key results from the measurements including the amount of delay dispersion (time-delayed echoes), and the stationarity time (how fast the fundamental characteristics of the channels change). Further topics include the directional dispersion (echoes coming from different directions) and how propagation effects in the mmWave band differ from those at lower frequencies. The results can serve as a basis for the design of next-generation V2X communications systems.

Summary contributed by Roshan George (Author):
Accurate perception and mapping of the environment is a critical component for automated transportation systems. However, complex environments such as urban junctions, parking lots, and highways present significant challenges for traditional on-board sensing technologies. One such challenge is the occurrence of occlusions, which can limit an autonomous system's ability to map its surroundings accurately.
Collaborative driving has emerged as a promising solution for addressing these challenges. In this paradigm, connected and autonomous vehicles collaboratively receive and share information with other agents in their environments. These agents may include other connected vehicles or fixed infrastructure equipped with sensing capabilities. By leveraging V2X communication technologies, these agents can share information regarding their environments. These shared data can be used to construct an environmental map containing both dynamic and static information to support safety-critical autonomous driving tasks. Thus, the collaboration process becomes a map fusion task.
This study investigates technologies that enable infrastructure-assisted collaborative driving and map fusion frameworks. It begins by examining the key technology components, including the various sensing modalities employed and the perception and mapping techniques used in both single-agent and multi-agent systems. This analysis offers valuable insights into the comparative strengths and weaknesses of the technologies that underpin collaborative driving with infrastructure support. This study then presents a real-world case study to explore how infrastructure-assisted collaborative driving can be implemented in practice. This case study highlights critical issues that must be considered such as real-time processing requirements, privacy protection, data security, the possibility of adversarial attacks and appropriate countermeasures. Finally, the economic feasibility of deploying vehicle-infrastructure collaborative driving systems is evaluated.
The findings of this study indicate that the deployment of a cooperative V2I system necessitates the careful consideration of the varying use-case requirements to achieve an efficient and effective system. Furthermore, large-scale deployment of V2I cooperative sensing systems, which offers benefits like improved road safety and traffic efficiency, requires collaboration among research institutes, automotive OEMs, and government organizations. These entities must work together to define the functional requirements for safety-critical use cases and determine the necessary level of infrastructure involvement to design and deploy cost-effective and efficient V2I systems. The functional requirements vary based on the deployment environment and use-case. For example, in urban junctions, a wider sensor coverage may be necessary, and both static and dynamic information can be constantly shared with the connected vehicle at a low frequency. Conversely, environments such as highways may necessitate a narrower sensor coverage with a longer effective range, sharing only dynamic, safety-critical information about objects posing immediate collision risks or those present in the vehicle's current path.
By comprehensively examining the enabling technologies, real-world implementation challenges, and economic considerations, this study provides a thorough overview of the current state and future potential of infrastructure-assisted collaborative driving systems.
