Collaborative Research: SWIFT: LARGE: DYNAmmWIC: Dynamic mmWave Spectrum Sharing Techniques for Public Safety Communications

正在进行的新冠肺炎再次突显了公共安全通信在保护公共安全人员、确保救生服务方面的重要性。随着5G网络过渡到更高的频率，包括毫米波频谱，将PSC解决方案集成到这一新频谱中成为一个挑战。提高数据速率、减少延迟和提高密度将导致实现高质量实时视频流和超低延迟通信等对生命至关重要的PSC用例。这些用例增加了毫米波频谱中对PSC的潜在需求。传统的频谱管理解决方案，如分配专用PSC频段，是不可持续的。该项目开发用于公共安全通信的动态毫米波频谱共享解决方案(DYNAmmWIC)，以允许在毫米波频谱中使用新的PSC用例，并设计毫米波频谱。这一愿景需要无线电、网络运营管理和网络架构层面的创新共存。该项目开发的解决方案有可能从根本上改变毫米波频谱的使用，加速无线行业为6G解决方案做好准备，同时节省大量成本。该项目探索了四个主要目标，以提供从无线电硬件到网络架构的完整的雷达-5G-公共安全通信(PSC)共存解决方案：(1)开发联合雷达通信(JARC)系统，在商业和公共安全车辆中使用相同的波形进行雷达传感和数据传输。(2)开发了一种毫米波频谱共享解决方案，以动态管理毫米波频谱中PSC、雷达传感、5G和V2V通信、行人接入和回程等业务的共存。(3)开发了一种新的毫米波下一代无线接入网络(NG-RAN)体系结构，通过成熟的编排工具实现更高的RAN协作和集成，以便在真实的试验台上快速开发解决方案迭代。(4)综合评价方案是对已开发技术的补充。在俄亥俄州立大学实施的JARC系统将增强iLNK，这是一种全市范围的远程访问无线试验床。ILNK是由UNL与林肯市合作开发的，事实证明，在与新冠肺炎相关的限制期间，iLNK是一个有价值的远程教学工具。PIS将致力于推出可以在远程访问的iLNK试验床上进行的教育模块，从而降低无线教育的门槛。这个项目将由一个高度多样化的私人投资机构团队进行，他们在富有成效的协作和对多样性的影响方面有着长期的记录。建议的解决方案经过严格测试，向当地和国家利益相关者展示下一代PSC模型。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The ongoing COVID-19 has, once more, highlighted the importance of public safety communications (PSC) in protecting public safety personnel and ensuring life-saving services. As 5G networks transition to higher frequencies, including the mmWave spectrum, integration of PSC solutions into this new spectrum becomes a challenge. Increased data rates, reduced delays, and improved density would lead to the realization of life-critical PSC use cases such as high-quality real-time video streaming and ultra-low-delay communication. These use cases increase the potential demand for PSC in the mmWave spectrum. Conventional spectrum management solutions, such as allocating dedicated PSC bands, are not sustainable. This project develops dynamic mmWave spectrum sharing solutions for public safety communications (DYNAmmWIC) to allow for novel PSC use cases in the mmWave spectrum and design the mmWave spectrum. This vision requires the coexistence of innovations in the radio, network operation management, and network architecture levels. The developed solutions in this project have the potential to fundamentally transform mmWave spectrum usage and accelerate the readiness of the wireless industry for 6G solutions while saving significant costs. The project explores four main goals to provide a complete radar-5G-public safety communications (PSC) coexistence solution from radio hardware to the network architecture: (1) A joint-radar communication (JARC) system is developed by using the same waveform for both radar sensing and data transmission in commercial and public safety vehicles. (2) A mmWave spectrum sharing solution is developed to dynamically manage the coexistence of operations for PSC, radar sensing, 5G, and V2V communications, pedestrian access, and backhaul in the mmWave spectrum. (3) A novel mmWave next-generation radio access network (NG-RAN) architecture is developed, allowing higher RAN co-operation and integration through proven orchestration tools for rapid development iterations of solutions on a real testbed. (4) A comprehensive evaluation plan complements the developed techniques. The JARC system, implemented at OSU, will augment iLNK, a city-wide, remotely accessible wireless testbed. iLNK is developed at UNL in collaboration with the City of Lincoln, which has proven to be a valuable remote teaching tool during the COVID-19-related restrictions. PIs will work to roll-out educational modules that can be conducted on the remotely accessible iLNK testbed, lowering the barrier to wireless education. This project will be conducted by a highly diverse team of PIs with a long track record of productive collaboration and impacts on diversity. Proposed solutions are rigorously tested to demonstrate a next-generation PSC model to local and national stakeholders.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.
