Next-generation (NextG) wireless networks are anticipated to revolutionize various applications, such as interactive real-time applications like Augmented Reality (AR), while meeting the high Quality-of-Experience (QoE) requirements expected by users. To achieve these goals, NextG networks are undergoing a transformation toward a white-box architecture, characterized by openness, intelligence, and a focus on user needs. Therefore, it is both timely and important to address autonomous resource management within the NextG paradigm. This project aims to facilitate the transition from traditional black-box network designs to a white-box network architecture, which will significantly reduce costs and enhance QoE performance at its core. The findings of this project will be integrated into the curricula of all participating institutions. Furthermore, this project is committed to promoting the engagement of women and underrepresented minority (URM) students through research opportunities and outreach activities at their respective institutions. Mechanisms will be established to foster leadership and participation from URM groups in an annual high-profile research workshop held at OSU.O-RAN is an operator-driven alliance dedicated to the advancement of radio access networks (RAN) toward an open architecture. This research focuses on harnessing the advanced capabilities of O-RAN, with a specific emphasis on edge-assisted low-latency AR as a key use case, to address autonomous resource management in the NextG paradigm. The research employs a data-driven approach across multiple time scales, using Bayesian optimization (BO) as a sample-efficient online learning and black-box optimization tool. The research develops versatile techniques and building blocks to optimize the QoE performance, structured around three interconnected thrusts: (i) developing a provably efficient multi-time-scale data-driven BO framework integrated with O-RAN, (ii) achieving collaborative BO for multi-RAN learning and optimization, and (iii) applying the developed BO frameworks to edge-assisted low-latency AR applications. The research establishes the analytical foundations and algorithmic frameworks that will be integrated with open-source full-stack O-RAN implementations. The evaluation process involves simulations based on 3GPP standards in ns-3, as well as collaborations with industry partners including AT&T, Qualcomm, and Nokia Bell Labs. Real- world trace data and production-grade O-RAN platforms will be leveraged for evaluation purposes. The outcomes of this research not only contribute to advancing knowledge in machine-learning-enabled NextG systems design but also address critical needs within the broader machine learning and networking research communities.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(NextG)无线网络预计将给各种应用带来革命性的变化，例如增强现实(AR)等交互式实时应用，同时满足用户期望的高体验质量(QOE)要求。为了实现这些目标，NextG网络正在向以开放、智能和关注用户需求为特征的白盒架构转型。因此，在下一代范式中解决自主资源管理问题既及时又重要。该项目旨在促进从传统的黑盒网络设计向白盒网络架构的过渡，这将显著降低成本，并从核心上提升QOE性能。该项目的调查结果将纳入所有参与机构的课程。此外，该项目致力于通过各自机构的研究机会和外联活动，促进妇女和代表不足的少数群体学生的参与。将建立机制，以培养URM团体在OSU举行的年度高调研究研讨会的领导力和参与。O-RAN是一个运营商驱动的联盟，致力于推动无线接入网络(RAN)向开放架构发展。这项研究的重点是利用O-RAN的高级能力，特别强调边缘辅助的低延迟AR作为关键用例，以解决NextG范式中的自主资源管理。这项研究采用了跨越多个时间尺度的数据驱动方法，使用贝叶斯优化(BO)作为样本高效的在线学习和黑箱优化工具。这项研究开发了多种技术和构建块来优化QOE性能，围绕三个相互关联的推动：(I)开发一个与O-RAN集成的可证明有效的多时间尺度数据驱动的BO框架，(Ii)实现用于多RAN学习和优化的协作式BO，以及(Iii)将所开发的BO框架应用于边缘辅助的低延迟AR应用。这项研究建立了将与开源全栈O-RAN实现集成的分析基础和算法框架。评估过程包括在ns-3中基于3GPP标准的模拟，以及与行业合作伙伴的合作，包括AT&amp；T、高通和诺基亚贝尔实验室。将利用真实世界的跟踪数据和生产级O-RAN平台进行评估。这项研究的结果不仅有助于提高支持机器学习的NextG系统设计方面的知识，而且还满足了更广泛的机器学习和网络研究社区的关键需求。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。
