美国近期采用的公民宽带无线电服务（CBRS）使两层商业用户能够与第三层现有用户共享频谱。环境感知能力运营商（ESCs）可以进一步协助这种共享，它们监测频谱占用情况，以确定频谱的使用在何时不会对现有用户造成损害。该框架影响企业竞争方式的两个关键方面是不同的环境感知能力运营商所提供信息的差异以及企业可能接入频谱的不同层级。我们建立了一个博弈论模型，该模型涵盖了这两个特征，并对其进行分析以深入了解它们的影响。具体而言，我们考虑优先接入（PA）层级的企业能够接入授权频段和非授权频段，而一般授权接入（GAA）层级的企业只能接入非授权频段。优先接入层级和一般授权接入层级的企业争夺用户。我们的分析表明，必须明智地选择非授权和授权带宽的数量，以实现社会福利的最大化。我们还表明，优先接入层级的企业进行有限的非授权接入对用户剩余以及社会福利都是有益的。
The Citizens Broadband Radio Service (CBRS) recently adopted in the U.S. enables two tiers of commercial users to share spectrum with a third tier of incumbent users. This sharing can be further assisted by Environmental Sensing Capability operators (ESCs), that monitor the spectrum occupancy to determine when use of the spectrum will not harm incumbents. Two key aspects of this framework that impact how firms may compete are the differences in information provided by different ESCs and the different tiers in which a firm may access the spectrum. We develop a game theoretic model that captures both of these features and analyze it to gain insight into their impact. Specifically, we consider a priority access (PA) tier firm has access to the both a licensed band and an unlicensed band, and a general authorized access (GAA) tier firm has access only to the unlicensed band. The PA tier and GAA tier firms compete for users. Our analysis reveals that the amount of unlicensed and licensed bandwidth must be chosen judiciously in order to maximize the social welfare. We also show that a limited amount of unlicensed access by the PA tier firm is beneficial to the user's surplus as well as to the social welfare.
