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.

该 EARS（增强无线电频谱接入）计划是为了响应 2010 年国会授权的《关于发动无线宽带革命的总统备忘录》而设立的，该备忘录是国家宽带计划的一部分。它在 2010 年国情咨文和后来的 2012 年中产阶级税收减免和创造就业法案（该法案超过 1/3 涉及无线电频谱）、PCAST​​ 2012 报告 [总统科学和顾问委员会技术]（要求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领域的领导地位）。该计划的目的是确定大胆的新概念，这些概念有可能显着提高无线电频谱利用效率、保护无源传感服务，并使传统上服务不足的美国人能够从当前和未来的无线技术中受益。商品和服务。从 2015 年初 FCC 以超过 450 亿美元的价格竞标 65MHz 频谱来看，这对国家经济产生了巨大影响。它将让科学、工程、工业、民用和军事用户能够使用无线电频率（ RF）频谱。要实现扩大 RF 频谱商业接入的国家目标，需要过渡到新的频谱接入系统 (SAS) 框架，该框架将支持更广泛的频谱共享。传统频谱管理过于依赖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，该框架将能够在多个维度（即时间、空间和用户级）对频谱资源进行更细粒度的动态管理。促进所有类别的频谱用户之间增加共享，包括那些依赖无源传感系统的用户。拟议的研究具有技术和经济两方面的内容。对于技术部分，它将开发一个实施现有保护区（IPZ）的框架，该框架利用 SAS 数据库和频谱传感数据来动态调整禁区的地理轮廓。这将扩大次要用户 (SU) 与现有用户 (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访问权，用于调用排除其他无线电设备在 IU 频谱中进行传输的选项 (OTE)。该计划是将 IPZ 和 OTE 概念整合到博弈论模型中。 此外，它将开展详细的案例研究，考虑与商业用户共享 3.5 GHz、5 GHz 和 AWS-3 频段政府频谱的现实挑战。 本研究旨在提供一个在技术上和经济上都可行的实用框架，用于实施激励兼容的动态共享解决方案作为 SAS 框架的一部分。
