Next generation 5G and beyond wireless systems are rapidly evolving to support positioning as a native feature using their communication infrastructure. Notwithstanding the dependence on a densely deployed infrastructure (for accurate positioning), the overhead of such an infrastructure- based positioning approach can bring significant degradation to communication performance, and warrants timely attention. The proposed research explores a fundamentally different paradigm of communication-aware collaborative positioning, whereby the burden of positioning is offloaded to client devices in an intelligent, communication-aware and collaborative (peer-peer) manner that reduces overhead and improves spatial reuse to preserve communication performance, without compromising on positioning accuracy. The proposed research will pave the way for future wireless networks that double up as sensing platforms through a seamless coexistence of positioning and communication. It can impact society in more ways than one, ranging from enabling novel 5G applications that benefit consumers (e.g. immersive applications) and enterprises to more broadly enabling infrastructure-light/free positioning that is central to challenging public-safety and remote orchestration environments. It aims to inform upcoming and future IEEE and 3GPP standards by demonstrating the potential of collaborative positioning and advocating for its accommodation in the standard specifications. It will also impact the industry that is actively working on positioning through demonstration of its results.The proposed research aims to take an important step towards this vision by addressing three key challenges: (i) characterizing the tradeoff between communication and positioning performance, and leveraging the paradigm of collaborative positioning to design a seamless and efficient coexistence framework; (ii) realizing coexistence in practice for both asynchronous (WiFi) and synchronous (cellular: LTE and new radio, NR) access systems through scalable, distributed medium access mechanisms; and (iii) enabling and leveraging positioning to go beyond coexistence and optimize communication performance as we move to more challenging high frequency millimeter-Wave systems that are burdened by measurement overhead. Through the design of an analytically-sound coexistence framework along with an integrated (WiFi + LTE/NR) 5G testbed network deployment, we will propose a suite of innovative algorithms and protocols that allow us to not only strike an efficient balance in both communication and positioning performance, but also enhance communication performance in future high frequency wireless systems. Such a framework will have broader implications beyond positioning and will apply to several other sensing problems under the much-anticipated paradigm of “joint communication and sensing” in our future 6G networks.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.

下一代5G及以后的无线系统正在迅速发展，以使用其通信基础架构作为本地功能来支持定位。尽管依赖密度部署的基础架构（用于准确定位），但这种基于基础架构的定位方法的间接费用可以给沟通绩效带来重大降低，并保证及时关注。拟议的研究探讨了沟通感知的协作定位的根本不同的范式，从而以智能，通信感知和协作（PEER-PEER）方式将定位的燃烧插入到客户设备上，从而降低了开销并改善空间重用以保持沟通性能，以保持沟通性能，而无需在位置准确的情况下兼容。拟议的研究将为未来的无线网络铺平道路，通过定位和沟通的无缝共存为传感平台加倍。它可以以多种方式影响社会，从启用有益于消费者（例如沉浸式应用程序）和企业的新型5G应用程序到更广泛地实现基础设施/免费定位，这是挑战公共安全和远程编排环境的核心。它旨在通过证明协作定位的潜力并倡导其在标准规范中的适应性来告知即将到来的IEEE和3GPP标准。它还将影响正在通过证明其结果来积极定位的行业。拟议的研究旨在通过解决三个关键挑战来迈出重要的一步：（i）表征交流和定位绩效之间的权衡，并利用协作定位的范式，以设计一个无缝和高效的共处框架框架； （ii）通过可扩展的，分布式的介质访问机制来实现异步（WiFi）和同步（蜂窝：LTE和新无线电，NR）访问系统的实践共存； （iii）随着我们挑战高频毫米波系统，通过测量开销燃烧的高频毫米波系统，使和利用定位超越了共存并优化沟通性能。通过设计分析性共存框架以及集成（WiFi + LTE/NR）5G测试床网络部署，我们将提出一套创新的算法和协议，不仅使我们不仅可以在通信和定位性能中取得高效的平衡，还可以在未来的高频无效系统中提高通信性能。这种框架将在定位之外具有更广泛的含义，并将适用于我们未来的6G网络“共同沟通和敏感性”的备受期待的其他几个敏感性问题。该奖项反映了NSF的法定任务，并通过使用基金会的智力和更广泛的影响来审查Criteria，通过评估来诚实地通过评估来诚实地支持。
