The millimeter wave (mmWave) frequencies and other bands above 6 GHz are a new and promising frontier for cellular wireless communications and the focus of the fifth-generation (5G) standardization efforts. Due to the massive available bandwidths, the mmWave frequencies offer the possibility of orders of magnitude greater capacity than current cellular systems in the highly congested bands below 3 GHz. However, a key challenge in realizing mmWave mobile cellular networks is energy consumption. Mobile devices and small-cell access points must operate under highly-constrained power budgets, and developing mmWave systems within these power limits is a formidable task. This project will investigate energy consumption from a system's perspective to address the issues in an integrated and coherent manner. The project will develop mathematical models for understanding energy and performance tradeoffs. New technologies for the radio frequency (RF) circuits, antenna array system, signal processing, and network protocols will be jointly developed to optimize performance and deliver energy-efficient mmWave devices.The research work will pursue four key thrusts: Thrust 1 will seek to understand the fundamental relation between throughput, processing power, and spectral emission constraints, and optimizes this tradeoff by dynamically controlling key energy drivers including bandwidth, quantization resolution, antenna architecture, and waveform selection. This is combined with novel energy-aware scheduling policies and signal processing techniques. Thrust 2 will focus on idle mode power savings and associated problems of energy-efficient directional channel estimation and delay in dynamic environments. Thrust 3 will develop fundamental circuits technologies that enable Thrusts 1 and 2, in particular the novel techniques for both high-efficiency power amplifiers and low-power fully digital RF transceivers. Thrust 4 will obtain the necessary channel models and build circuit prototypes to validate the concepts in Thrusts 1 to 3.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.

毫米波（mmWave）频率和6ghz以上的其他频段是蜂窝无线通信的一个新的、有前途的前沿领域，也是第五代（5G）标准化工作的重点。由于大量的可用带宽，毫米波频率提供了比目前在3ghz以下高度拥塞频带中的蜂窝系统更大的数量级容量的可能性。然而，实现毫米波移动蜂窝网络的一个关键挑战是能耗。移动设备和小型基站接入点必须在高度受限的功率预算下运行，在这些功率限制下开发毫米波系统是一项艰巨的任务。本项目将从一个系统的角度调查能源消耗，以综合和连贯的方式解决问题。该项目将开发数学模型，以理解能源和性能之间的权衡。双方将共同开发射频（RF）电路、天线阵列系统、信号处理和网络协议的新技术，以优化性能并提供高能效毫米波设备。研究工作将追求四个关键推力：推力1将寻求理解吞吐量，处理能力和频谱发射约束之间的基本关系，并通过动态控制关键能量驱动因素（包括带宽，量化分辨率，天线结构和波形选择）来优化这种权衡。这与新颖的能量感知调度策略和信号处理技术相结合。推力2将专注于空闲模式下的节能以及动态环境下节能定向信道估计和延迟的相关问题。推力3将开发基础电路技术，使推力1和推力2成为可能，特别是高效功率放大器和低功率全数字射频收发器的新技术。推力4将获得必要的通道模型，并建立电路原型，以验证推力1至推力3中的概念。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
