- Abstract
- Citizen Broadband Radio Service (CBRS) uses the spectrum of the 3.5 GHz band. It allows general authorized access (GAA) users to access the spectrum through the spectrum access system (SAS) while ensuring no interference with incumbent users and priority access license (PAL) holders. This work proposes a novel channel allocation scheme for GAA users, implemented through the SAS. The proposed schemes are based on a cooperative game-theoretic approach called the hedonic coalition formation (HCF) game and genetic algorithm (GA). In the former, each coalition represents a group of users sharing the same channel within the 3.5 GHz band, whereas the coalitions are formed to minimize cochannel interference (CCI). In the latter, GA is utilized to find a suboptimal channel allocation. This work demonstrates the effectiveness of the proposed schemes in comparison with Approach 1 in the standard.
