The present report contains the third volume (Volume III) of 5GAA WG1 agreed use case (UC) descriptions for Use Cases developed within the 5GAA and consolidated in WG1. The results and conclusions of this report, and of the future use case descriptions and related communication requirements, are intended to serve as input for the work of other WGs in 5GAA, as well as sources for input and feedback to standardization activities, e.g., in 3GPP.

5G Automotive Association is pleased to invite you to our online session, “V2X Application Adaptation based on Predictive QoS Changes“, taking place on January 27, from 3:00 to 4:30 PM (CET).

The speakers from Huawei (Antonio Consoli, Ali Hamidian) and Tencent (Lei Yixue) will present the highlights of the PRESA Technical Report on enhancing the framework for V2X application adaptation when a QoS change is predicted in the network.

Following on the recent publication of a technical report on the Predictive QoS and V2X Service Adaptation (PRESA) Work Item, the 5G Automotive Association is hosting an online session on Friday, January 27, from 3:00 to 4:30 PM (CET).

The session, “V2X Application Adaptation based on Predictive QoS Changes”, will be led by Huawei’s Antonio Consoli and Alimi Hamidian, and Tencent’s Lei Yixue. As the leading contributors to this publication, they will present the highlights of the PRESA technical report on enhancing the framework for V2X application adaptation when a QoS change is predicted in the network.

The three speakers will explain the methodology for analysing V2X use cases that use predictive QoS information to enable V2X application adaptation for the vehicles, as well as the coordination between 3GPP and 5GAA to promote end-to-end solutions and standards for QoS prediction and V2X application adaptation.

Registrations are now open.

Brussels – Today, we join together to reaffirm our continued support for the rapid, widespread deployment of vehicle-to-everything (V2X) technologies in order to further improve safety on American roads. V2X, which allows communication between vehicles, infrastructure, and other road users such as pedestrians and bicyclists, provides drivers with crucial warnings necessary to improve safety. Our organizations represent the full breadth of the transportation stakeholder community and are aligned in our belief that the widespread deployment of V2X technologies can dramatically reduce crashes and fatalities on American roads for all road users.

We believe that 2023 will be a pivotal year for V2X deployment. Transportation stakeholders have aligned behind one V2X technology, cellular vehicle-to-everything (C-V2X), clearing the way for a unified, nationwide approach to the deployment of this tool. The U.S. Department of Transportation (USDOT) recently held a V2X Summit in which it committed to the development of a Nationwide V2X Deployment Plan, lending crucial leadership to the deployment of these technologies. The Federal Communications Commission (FCC) is poised to deliver much needed regulatory clarity for the deployment of C-V2X through the issuance of pending waivers to operate in the 5.9 GHz Band. Multiple stakeholders are making significant investments in CV2X today, and the waivers under consideration at the FCC are urgently needed to move forward with deployment plans.

We wish to express our appreciation for the work being done by USDOT, FCC, and the National Telecommunications and Information Administration to maintain interference-free dedicated spectrum and quickly establish the regulatory framework that will allow for widespread deployment of C-V2X. This includes the FCC first allowing near-term deployments to move forward under waiver authority, the FCC issuing a Second Report and Order that sets the final rules for the future of these technologies and protects the spectrum from interference, and USDOT adopting a Nationwide V2X Deployment Plan. As these steps are undertaken, our organizations will continue to work collaboratively to resolve remaining issues to deploy CV2X, giving drivers and other road users a critical tool to improve safety, reduce crashes, and decrease fatalities.

About 5GAA

The 5G Automotive Association (5GAA) is a global, cross-industry organization of over 130 members made of leading global automakers, Tier-1 suppliers, mobile operators, semiconductor companies, and test equipment vendors. It works together to develop end-to-end solutions for future mobility and transport services. 5GAA is committed to helping define and develop the next generation of connected mobility, automated vehicle, and intelligent transport solutions based on C-V2X.

The current development of communication technologies opens up new opportunities and enables novel V2X (Vehicle-to-Everything) services in the automotive area. However, specific design constraints faced by the automotive industry lead to complex implementations, as the allowed positions and mounting spaces for antennas, communication modules, and the required cabling can be very limited. These challenges commonly require vehicular-Distributed Antenna System (DAS) approaches.

This white paper provides an analysis of the motivation for and needs associated with vehicular-DAS, as well as proposals for some vehicular-DAS design solutions. In addition, it describes the implementation feasibility and potential benefits of vehicular-DAS based on measured computer simulation results, and evaluates potential vehicular-DAS impacts on current specifications.
