This project is addressing the following questions:(1) What dynamic spectrum sharing mechanisms provide the most benefit to both types of users? Preemptive spectrum use by public safety users may incur undue cost to commercial users which have their connections cut. At the other extreme, simple sharing that allocates channels whenever available regardless of caller type may incur too high a blocking to public safety. Many intermediate mechanisms can be formulated. These mechanisms can all be compared with the current mechanism that divides the total bandwidth into rigidly segregated public safety and commercial sub-bands. (2) What is the cost of choosing these different mechanisms in terms of blocking for public safety users and economic cost to commercial users?This project is developing methods that will allow a more precise characterization of the benefit of sharing mechanisms and techniques for more optimal sharing mechanisms. Methods that draw on reinforcement learning and network pricing are being applied to the problem of developing optimal sharing mechanisms. This effort will help quantify the benefit of dynamic spectrum sharing and provide assurances to public safety and commercial users that the sharing concept will meet their separate needs.

该项目正在解决以下问题：（1）哪些动态频谱共享机制为这两种用户提供了最大的好处？ 公共安全用户的先发制频谱使用可能会给削减连接的商业用户带来不当成本。 在另一个极端，简单的共享，无论呼叫者类型如何，都可以分配渠道，这可能会导致公共安全的阻碍。可以制定许多中间机制。 这些机制都可以与将总带宽分为严格隔离的公共安全和商业子兰的当前机制。 （2）在阻止公共安全用户和对商业用户的经济成本方面选择这些不同机制的成本是多少？该项目正在开发方法，以更精确地表征共享机制和技术的好处，以实现更优化的共享机制。 利用强化学习和网络定价的方法正在应用于开发最佳共享机制的问题。这项工作将有助于量化动态频谱共享的好处，并为公共安全和商业用户提供保证，即共享概念将满足其单独的需求。
