Abstract Traditional static spectrum allocation can not adapt to the future development of wireless communication services, leading to limited profits for operators and poor Quality of Service (QoS) for users. To solve the problem, this paper proposes a three-layer spectrum sharing model including operators, users, and a spectrum leasing platform, where A operators place their excess spectrum in the leasing platform for B operators to lease. This paper considers a situation where multiple operators cooperate to share portions of spectrum but compete to serve users, then the optimal spectrum leasing strategy is studied. The goal of this paper is to find the optimal leasing strategy for both A and B operators to maximize their profits while guaranteeing the QoS for users. Numerical results show that the proposed strategy not only improves the efficiency of spectrum utilization effectively but also shows a big advantage in increasing operators’ profits.
