摘要

摘要: 传统的静态频谱分配方式难以适应未来无线通信业务的发展需求，可能导致运营商业务和用户服务质量受到限制。针对此问题，该文建立了一个包括频谱租赁服务平台层、运营商层及用户层的多运营商频谱共享模型。在该模型中，多个A类运营商将其多余频谱放置在频谱租赁服务平台，供B类运营商租赁，B类运营商与多个A类运营商既竞争用户又共享部分频谱。该文形成了以各类运营商利润最大化为优化目标，以A类运营商的频谱出租量和B类运营商租赁的频谱种类及数量为优化变量的最优化问题，并求得最优解。仿真结果表明，所提策略在保证用户服务质量(QoS)的同时，显著提高频谱资源利用率，并使运营商利润大幅增加。

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.
