On November 8th, the IoV Joint Working Group of FuTURE Mobile Communication Forum held its 25th meeting in Beijing. Li Yan, Chairman of the working group and Vice President of Technology Standards at Qualcomm, along with experts from Qualcomm, Nebula Link, OPPO, Vanjee, Xidian University, and other organizations, engaged in discussions about the IoV Joint Working Group's research directions. They also reviewed white papers on topics such as safety analysis for LTE V2X warning-type application functions, practical explorations of specific V2X scenarios, and sidelink ranging and positioning.

The Functional Safety Analysis Project of LTE V2X Warning-Type Application Functions jointly initiated by Qualcomm, Nebula Link, and CICT Mobile, has been completed, with nearly 30 companies participating in the drafting of the report. Chen Shuping, an expert from Qualcomm, presented the content and progress of this white paper. He summarized that the functional safety analysis methodology outlined in GBI/T 34590 should be expanded to enhance the entire functional safety framework and include V2X within its scope. Based on the three typical V2X scenarios selected for this study, the ASILs of potential hazards generally ranged from "no functional safety requirements" to "QM," meaning that a QM-level functional safety design can meet the needs of V2X warning-type application functions. The analysis process and results for these three types of LTE-V2X warning-type applications are applicable to all LTE-V2X warning-type applications. Future V2X functional safety analysis efforts should focus on the timeliness and accuracy of message transmission from the TxV and RSU sides, ensuring the use of correct protocol stack versions on the sides, proper message padding as per standards, and timely message delivery.

ISO is set to conduct a V2X functional safety analysis in 2025, with CATARC serving as the responsible organization. Li Yan suggested that the lead parties of the Functional Safety Analysis Project of LTE V2X Warning-Type Application Functions coordinate with CATARC and recommend the findings of this report to the Chinese delegation to provide reference and support during the international standard-setting process. This will help China play a more influential role in the V2X functional safety domain and promote the global application of domestic research outcomes.

Wang Yizhi from Nebula Link introduced the "Practical Exploration of Specific V2X Scenarios" research. This research focuses on C-V2X scenarios that are urgent for deployment, especially those unique to V2X or with a special value that complements single-vehicle intelligence. It also addresses the technical barriers to V2X commercial deployment. According to Wang Yizhi, the study includes verifying the effectiveness of V2X applications in specific scenarios—such as curves, interchanges, adverse weather conditions, intersections with obstructions, and the presence of out-of-control vehicles ahead—using both simulation and real-vehicle testing. The goal is to determine the applicability of V2X technology and identify its advantages. The research is scheduled to conclude in March 2025, with a white paper to be released. Li Yan emphasized that further industry communication on the scenarios discussed in the report would add significant value to IoV research efforts.

Zhao Zhenshan from OPPO introduced the Sidelink Ranging and Positioning research led by OPPO, which was initiated in January 2024. The research primarily covers absolute and relative positioning, ranging/direction finding, sidelink-based positioning methods, sidelink signal design, resource allocation, and related physical-layer processes. It also examines the system architecture for positioning and signaling processes, such as configuration and measurement reporting. The white paper for this research was expected to be completed by the end of 2024.

At the meeting, Li Yan offered several suggestions for the Working Group's future efforts.
The first is the deepening of functional safety analysis. Given the critical role of LTE V2X warning-type applications in vehicle control, it is essential to enhance their functional safety analysis. This should align with ISO's research efforts to ensure that the influence of V2X safety on functional safety is comprehensively addressed.

The second is industry cooperation and promotion. Strengthen collaboration with CATARC and CAICV, disseminating the Working Group's advancements in V2X application optimization and enhancing the user experience of V2X applications through joint research.

The third is UAV and Sidelink research. Initiate studies on the application of Sidelink in UAV operations, in collaboration with the FuTURE Forum's DLA WG. It is recommended that the DLA WG explore the applications of Sidelink in UAVs and low-altitude environments. Meanwhile, the Working Group will focus on enhancing and optimizing Sidelink for UAVs. Active participation in the DLA WG's subgroups—including TG2 (Low-Altitude Frequency Task Group), TG3 (Communication and Sensing Task Group), TG7 (Low-Altitude Equipment and Environment Group), and TG9 (Low-Altitude Aircraft Management and Service Group)—is recommended to discuss collaborative opportunities, with a particular emphasis on Sidelink communication demands in UAV and digital low-altitude applications.

The fourth is A2X communication frequency research. After defining requirements, initiate studies on the Sidelink communication frequencies needed for digital low-altitude scenarios. Ensure these studies also address frequency requirements for Sidelink-based positioning and sensing.

The fifth is the expanding of research scope. Broaden the scope of the Working Group to include fields related to autonomous driving, such as Navigation-on-Autopilot (NOA) and Navigation-based Optimization Planning (NOP). This will contribute to the advancement and implementation of autonomous driving technologies.
