Abstract

The General Authorized Access (GAA) users operate at the lowest priority in the Citizens Broadband Radio Service (CBRS) band. So they must not cause harmful interference to the higher priority users. In addition, the GAA users must cooperate with each other to minimize mutual interference and increase spectrum utilization. To achieve this goal the Wireless Innovation Forum (WInnForum), a standards body, has recommended three schemes. In this paper we study performance of one of the schemes, called Approach 3. To the best of our knowledge, there is no performance study available for Approach 3. WInnForum recommendations do not include any performance metrics to evaluate the schemes. We define few performance metrics which are relevant for Approach 3 and will be useful for the operators in deciding their operating parameters. We choose two actual locations and use real terrain and land cover data of continental USA in our study while illustrating the performance of Approach 3 in various configurations. Hence, we expect our result to be similar to practical implementations.
