Cellular vehicle-to-everything communication (C-V2X) is a promising solution to reduce road incidents and traffic in future smart cities by communicating critical safety and road information with connected and autonomous vehicles (CAVs). To guarantee safe and efficient operation of CAVs, emerging cellular networks must support services with ultra-reliability and low-latency requirements (e.g., emergency braking) together with mobile broadband applications that need very high data rates (e.g., high-definition maps). Meeting such stringent requirements for large number of CAVs is beyond the capacity of existing networks that operate at scarce sub-6 gigahertz frequencies. Furthermore, while high-frequency millimeter wave (mmWave) bands offer large bandwidth, mmWave communications pose new challenges in terms of reliability that stem from inherent propagation characteristics of mmWave signals. To address these challenges, the goal of this research is to develop a holistic framework that enables seamless multiplexing of heterogeneous C-V2X traffic over aggregated mmWave and sub-6 GHz frequencies, while taking into account unique limitations and complementary features of communications at each frequency band. This research is accompanied by a comprehensive educational plan that includes mentoring graduate and undergraduate students to participate in research and testbed development, as well as various outreach events for underserved students at local schools.This fundamental research enables inter-frequency range carrier aggregation to manage the heterogeneous vehicle-to-everything communication (C-V2X) traffic jointly over mmWave and sub-6 GHz bands and to optimize mobility management for connected and autonomous vehicles (CAVs), while addressing key challenges of mmWave links such as reliability and sparsity. Given the ongoing efforts by standardization groups are primarily focused on carrier aggregation over a single frequency range, new schemes for modeling, optimization, and performance analysis of C-V2X communications are required that account for fundamental differences between mmWave and sub-6 GHz communications. To this end, this framework brings forward novel solutions at the intersections of wireless networking, edge computing, graph theory, and reliability theory, to achieve the following key innovations: 1) Designing new flexible frame structures to dynamically manage the heterogeneous C-V2X traffic over the aggregated mmWave and sub-6 GHz frequency ranges; 2) Analyzing the end-to-end performance of the proposed multi-band radio access network (RAN) with advanced features such as RAN function splitting and edge computing capabilities; 3) Optimizing the mobility management for CAVs based on the derived end-to-end performance metrics; and 4) Developing a comprehensive simulation testbed to evaluate the proposed schemes. The anticipated results of the proposed research will advance C-V2X networks and expedite the deployment of CAVs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

蜂窝车到所有通信（C-V2X）是一种有前途的解决方案，可通过与连接和自动驾驶汽车（CAVS）传达关键安全和道路信息来减少未来智能城市的道路事件和交通。为了确保骑士的安全有效操作，新兴的蜂窝网络必须支持具有超级可靠性和低延迟要求（例如紧急制动）以及需要非常高数据速率的移动宽带应用程序（例如，高清图）的服务。满足大量骑士的严格要求超出了以稀缺6吉赫兹频率运行的现有网络的能力。此外，尽管高频毫米波（MMWave）带提供了较大的带宽，但MMWave Communications就可靠性带来了新的挑战，这源于MMWave信号的固有传播特征。为了应对这些挑战，这项研究的目的是开发一个整体框架，该框架能够通过汇总的MMWave和Sub-6 GHz频率对异质的C-V2X流量进行无缝的多路复用，同时考虑到每个频段的独特限制和互补的交流特征。 This research is accompanied by a comprehensive educational plan that includes mentoring graduate and undergraduate students to participate in research and testbed development, as well as various outreach events for underserved students at local schools.This fundamental research enables inter-frequency range carrier aggregation to manage the heterogeneous vehicle-to-everything communication (C-V2X) traffic jointly over mmWave and sub-6 GHz bands and to optimize mobility management for connected和自动驾驶汽车（CAVS），同时应对可靠性和稀疏等MMWave链接的主要挑战。鉴于标准化组的持续努力主要集中在单个频率范围内的载体聚集上，需要对C-V2X通信进行建模，优化和性能分析的新方案，以说明MMWave和Sub-6 GHz通信之间的基本差异。为此，该框架在无线网络，边缘计算，图理论和可靠性理论的交集中提出了新的解决方案，以实现以下关键创新：1）设计新的柔性框架结构以动态管理聚集的MMWave和Sub-6 Ghz频率范围的异质C-V2X流量； 2）分析提出的具有高级功能的多波段无线电访问网络（RAN）的端到端性能，例如RAN功能拆分和边缘计算功能； 3）根据派生的端到端性能指标，优化CAVS的移动性管理； 4）开发全面的模拟测试台以评估所提出的方案。拟议的研究的预期结果将推动C-V2X网络并加快骑士的部署。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估标准通过评估来获得支持的。
