Collaborative Research: Dynamic Exclusion Zones: Balancing Incumbent Protection and Spectrum Utilization Efficiency

EARS（增强无线电频谱接入）计划是为了响应国会授权的2010年总统关于释放无线宽带革命的备忘录，作为国家宽带计划的一部分。它在2010年的国情咨文和后来的2012年中产阶级税收减免和创造就业法案中被引用（超过三分之一的法案涉及无线电频谱），PCAST 2012年报告[总统科学技术顾问理事会]（呼吁大幅增加频谱共享的使用）和2013年总统备忘录（扩大美国在无线创新方面的领导地位）。该计划的目的是确定大胆的新概念，这些概念有可能有助于显著提高无线电频谱利用效率，保护被动传感服务，并使传统上服务不足的美国人能够从当前和未来的无线产品和服务中受益。这对国家经济的影响很大，正如2015年初FCC以超过450亿美元的价格竞标65 MHz频谱所看到的那样。它将使科学、工程、工业、民用和军事用户能够使用射频（RF）频谱，满足扩大RF频谱商业使用的国家目标需要过渡到一个新的频谱接入系统（SAS）框架，该框架将支持更广泛的频谱共享。传统的频谱管理过于依赖于将无线电隔离到静态禁区。该项目的目标是通过研究和开发支持动态禁区的新框架来应对这一挑战，这些框架将实现对多维度频谱资源的更细粒度、动态管理（即，时间、空间和用户类别），以促进所有类别的频谱用户之间的共享，包括那些依赖于被动感测系统的用户。拟议的研究既有技术方面的内容，也有经济方面的内容。在技术部分，它将制定一个实施现有保护区的框架，利用SAS数据库和频谱传感数据动态调整禁区的地理轮廓。这将扩大次级用户（SU）与现任用户（IU）共存的机会，而不会造成有害干扰。 对于经济部分，该项目将研究一种新的频谱接入权，用于调用选择权（OTE），以阻止其他无线电在IU频谱中传输。该计划是将IPZ和OTE概念整合到一个博弈论模型中。 此外，它还将进行详细的案例研究，考虑在3.5 GHz、5 GHz和AWS-3频段与商业用户共享政府频谱的现实挑战。 这项研究的目的是提供一个实用的框架，在技术上和经济上可行的激励兼容的动态共享解决方案的SAS框架的一部分。

This EARS (Enhancing Access to the Radio Spectrum) program was founded in response to the 2010 Presidential Memorandum on Unleashing the Wireless Broadband Revolution mandated by Congress as part of the National Broadband Plan. It was referenced in 2010 State of the Union and later on the Middle Class Tax Relief and Job Creation Act of 2012 (More than 1/3 of the bill deals with radio spectrum), the PCAST 2012 Report [President's Council of Advisors on Science and Technology] (which calls for vastly increased use of spectrum sharing) and the 2013 Presidential memo (Expanding America's Leadership in Wireless Innovation). The aim of this program is to identify bold new concepts with the potential to contribute to significant improvements in the efficiency of radio spectrum utilization, protection of passive sensing services, and in the ability for traditionally underserved Americans to benefit from current and future wireless-enabled goods and services. The impact is large on the economics of the Nation as seen on the last FCC bidding of 65MHz of the spectrum for over $45 billion early in 2015. It will enable access to science, engineering, industry, civilian and military users of the radio frequency (RF) spectrum.Meeting national goals for expanded commercial access to the RF spectrum requires transitioning to a new Spectrum Access System (SAS) framework that will support more extensive sharing of the spectrum. Legacy spectrum management relies too heavily on segregating radios into static exclusion zones. The goal of this project is to address this challenge by studying and developing new frameworks for supporting dynamic exclusion zones that will enable much finer-grained, dynamic management of spectrum resources in multiple dimensions (i.e., time, space, and by user-class) to facilitate increased sharing among all classes of spectrum users, including those that rely on passive sensing systems. The proposed research has both technical and economic components. For the technical component, it will develop a framework for implementing Incumbent Protection Zones (IPZs) that take advantage of the SAS database and spectrum sensing data to adjust the geo-contours of exclusion zones dynamically. This will expand opportunities for Secondary Users (SUs) to co-exist with Incumbent Users (IUs) without causing harmful interference. For the economic component, the project will investigate a new spectrum access right for invoking an Option-to-Exclude (OTE) other radios from transmitting in IU spectrum. The plan is to integrate the IPZ and OTE concepts in a game theoretic model. In addition, it will carry out detailed case studies that consider real-world challenges of sharing government spectrum with commercial users in the 3.5 GHz, 5 GHz, and AWS-3 bands. This research is intended to provide a practical framework that is both technically and economically viable for implementing incentive-compatible dynamic sharing solutions as part of the SAS framework.
