Unmanned aerial vehicle (UAV)-assisted communication has attracted significant interest from the industry, especially with regard to the vision of providing ubiquitous connectivity for beyond 5G (B5G) networks. in this article, we motivate the need for utilizing licensed spectrum for UAV-assisted communication and discuss its advantages such as reliability and security. We explore a new dimension to spectrum sharing by proposing a decentralized competitive open market approach-based model, where the different mobile network operators (MNOs) have the opportunity to lease the spectrum to UAV base stations (UAV-BSs), leading to new revenue generation opportunities. The proposed spectrum sharing mechanism is based on the logarithmic utility function and willingness to pay of each UAV-BS. We provide a trade-off analysis between spectrum sharing and price offered by the MNOs, highlighting the impact of the willingness to pay on the spectrum sharing. The results also highlight the behavior of price and spectrum shared w.r.t. time, thereby providing an insight into different performance regions until the algorithm converges to its optimal value. in addition, we also present future directions that could lead to interesting analyses, especially with regard to incentive- based spectrum sharing and security.

按需频谱：无人机辅助通信频谱共享的竞争性开放市场模式


无人机 (UAV) 辅助通信引起了业界的极大兴趣，特别是考虑到为超 5G (B5G) 网络提供无处不在的连接的愿景。在本文中，我们提出了利用许可频谱进行无人机辅助通信的需求，并讨论了其可靠性和安全性等优势。我们通过提出基于去中心化竞争性开放市场方法的模型来探索频谱共享的新维度，其中不同的移动网络运营商（MNO）有机会将频谱租赁给无人机基站（UAV-BS），从而带来新的收入一代的机会。所提出的频谱共享机制基于对数效用函数和每个无人机基站的支付意愿。我们提供了频谱共享和移动网络运营商提供的价格之间的权衡分析，强调了支付意愿对频谱共享的影响。结果还突出了价格和频谱共享随时间变化的行为，从而提供了对不同性能区域的深入了解，直到算法收敛到其最佳值。此外，我们还提出了可能导致有趣分析的未来方向，特别是在基于激励的频谱共享和安全方面。
