This project will develop new energy-efficient techniques to co-use wireless spectrum for both communications and sensing. The setting considered will be that of emerging cellular networks consisting of a dense deployment of base-stations (wireless infrastructure on cell towers) providing overlapping wireless coverage. By enabling co-use of spectrum, this research will result in both better connectivity and improved data rates to users, and improved sensing through radar technologies for locating and tracking mobile users. These technologies will thus enable new smart city services and applications. On the educational front, the project will lead to development of new educational materials. Outreach activities to middle and high school students will occur through widely-accessible lecture series. The proposed activities will pay special attention to promoting diversity and nurturing student talent. Finally, the results will be shared with industry through the industrial affiliates program of the Wireless Networking and Communications Group (WNCG) at The University of Texas at Austin. The proposed research is geared at developing a new class of energy efficient cross-layer resource allocation algorithms for joint management of base-station and spectrum resources in dense wireless networks. At the same time, mathematical models and tools based on stochastic geometry will be introduced enabling one to characterize and optimize energy-performance for dense deployments. The intellectual merit can be summarized along four thrusts: (a) Infrastructure and spectrum co-use for communications and radar/sensing, where the focus will be on algorithms for handling interference from a mixture of communications and radar waveforms; (b) Stochastic geometry models and tools for characterizing heterogeneous spectrum use over space, where Central Limit Theorems over space will be developed to characterize SINR and radar distortion performance; (c) Algorithms for mode switching and base-station activation, where load-dependent algorithms for network management will be developed that are cognizant of hysteresis costs associated with changing modes and activation states of base-stations; and (d) Managing user dynamics through directed association to reduce the frequency of change in the network, which will result in improved convergence behavior of management algorithms at various spatial scales.

该项目将开发新的节能技术，以共同使用无线频谱进行通信和传感。所考虑的设置将是新兴的蜂窝网络，包括密集部署的基站（蜂窝塔上的无线基础设施），提供重叠的无线覆盖。通过实现频谱的共同使用，这项研究将导致更好的连接和提高用户的数据速率，并通过雷达技术来定位和跟踪移动的用户。因此，这些技术将实现新的智慧城市服务和应用。在教育方面，该项目将导致编写新的教材。对初中和高中学生的外联活动将通过广泛的系列讲座进行。 拟议的活动将特别注重促进多样性和培养学生的才能。最后，研究结果将通过德克萨斯大学奥斯汀分校无线网络和通信组（WNCG）的工业附属计划与工业界分享。提出的研究是面向开发一类新的能源高效的跨层资源分配算法，在密集的无线网络中的基站和频谱资源的联合管理。 同时，将介绍基于随机几何的数学模型和工具，使人们能够表征和优化密集部署的能源性能。其知识价值可归纳为沿着四个方面：（a）通信和雷达/传感基础设施和频谱的共同使用，重点是处理通信和雷达波形混合干扰的算法;（B）用于表征空间上异质频谱使用的随机几何模型和工具，其中将发展空间上的中心极限定理以表征SINR和雷达失真性能;（c）用于模式切换和基站激活的算法，其中将开发用于网络管理的负载相关算法，其认识到与基站的改变模式和激活状态相关联的滞后成本;以及（d）通过定向关联来管理用户动态以减少网络中的变化频率，这将导致管理算法在各种空间尺度上的改进的收敛行为。
