The Citizen Broadband Radio Service (CBRS) band has three tiers of users. The General Authorized Access (GAA) has the lowest priority and operates without a license. A Spectrum Access System (SAS) is responsible for managing spectrum among the users. The FCC rules specify that GAA users be allocated resources in a fair manner, but the method to do so is left open. It is envisioned that there will be multiple SAS operators in a given region. Thus, fair partition of resources among SASs and fair allocation of spectrum to GAA users are important factors. In this paper, we present methods to partition resources among SASs and mechanisms that can be used by a SAS to allocate resources to a GAA user to ensure fairness.
