Over the last few years, discussions oriented toward defining sixth generation (6G) requirements and possible technologies have started to circulate within the wireless community. One of the key ideas will likely be to take steps to remove the conventional cell boundaries and facilitate enhanced joint uplink and downlink processing using many dispersed access points (APs). These ideas fall within the academic definition of cell-free massive multiple-input multiple-output (CFmMIMO). It alleviates the existing cell-edge and handover problems and improves energy efficiency. The primary limiting factor is achieving cell-free operation in a practically feasible way, with computational complexity and fronthaul requirements that are scalable to large networks with many users. This poses many important research questions that must be explored systematically and in-depth. This project firstly develops scalable artificial intelligence (AI)-based solutions. Together with the appropriate (cost-efficient) AP deployment planning tools (e.g., where to put the APs), these developments constitute a significant step toward enabling the low-latency and uniformly reliable wireless services at a lower cost. Given the international nature of the project, the project contributes to the development of a diverse workforce in AI and 6G wireless networks through the formation of international research teams integrating undergraduate and graduate students. Project research activities are organized into three thrusts. Thrust 1 develops scalable AI-based resource allocation solutions enabling the implementation of large-scale CFmMIMO. The developed solutions are further enhanced by exploring AI architectures applicable to large networks. This includes the security aspects, especially in the context of AI algorithms and architecture, and the cloud radio access network. Thrust 2 focuses on establishing network planning and waveform constraints to address scalable deployment solutions. This includes the development of infrastructure-aware minimum-cost AP deployment methodologies by taking into account the QoS requirements and available transport infrastructure. The developed methodologies are further augmented by developing a network-wide user signal detection method, accounting for the fronthaul capacity and the quantization resolution at each AP. This task also investigates how CFmMIMO can address many of today’s most challenging spectrum policy issues. Evaluation Thrust evaluates and analyzes the methodologies developed in Thrusts 1&2. This employs the existing US and European experimental testbeds and provides a continuous feedback cycle between theory and experimentation. The US team will build upon the prior experience with Colosseum. On the European side, the team will experiment with the Open Air Interface (OAI).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.

在过去的几年中，针对定义第六代（6G）要求的讨论和可能的技术已经开始在无线社区中散发。关键的想法之一可能是采取步骤去除常规的单元边界，并使用许多分散的访问点（AP）维持增强的关节上行链路和下行链路处理。这些想法属于无细胞大量多输入多出输出（CFMMIMO）的学术定义。它减轻了现有的细胞边缘和交换问题，并提高了能源效率。主要的限制因素是以几乎可行的方式实现无单元的操作，其计算复杂性和领先要求与许多用户的大型网络可扩展。这定位了许多重要的研究问题，必须系统地和深入探讨。该项目首先开发可扩展的人工智能（AI）的解决方案。这些发展与适当的（具有成本效益的）AP部署计划工具（例如，将APS放置在哪里）构成了迈向以较低成本实现低延迟和统一可靠的无线服务的重要一步。鉴于该项目的国际性质，该项目通过组建了本科生和研究生的国际研究团队的形成，有助于在AI和6G无线网络中发展潜水员劳动力。项目研究活动分为三个推力。推力1开发可扩展的基于AI的资源分配解决方案，从而实现大规模CFMMIMO。通过探索适用于大型网络的AI架构，可以进一步增强开发的解决方案。这包括安全性方面，尤其是在AI算法和体系结构的背景下以及云无线电访问网络。推力2着重于建立网络计划和波形约束，以解决可扩展的部署解决方案。这包括通过考虑QoS要求和可用的运输基础设施来开发基础架构感知最低成本AP部署方法。通过开发网络范围内的用户信号检测方法，考虑到每个AP的领先容量和量化分辨率，进一步增强了开发的方法。该任务还调查了CFMMIMO如何解决当今许多最挑战的频谱政策问题。评估推力评估和分析推力1和2中开发的方法。这采用了现有的美国和欧洲实验测试床，并在理论和实验之间提供了一个连续的反馈周期。美国团队将基于与罗马竞技场的先前经验。在欧洲方面，该团队将尝试使用露天界面（OAI）。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被视为通过评估而被视为珍贵的支持。
