摘要翻译：
无人机(UAV)以其高度的部署和调度灵活性被公认为是未来无线通信的一种很有前途的方式。在本文中，我们重点研究了在宏基站(MBS)下在某些区域提供下行数据卸载的临时部署无人机。由于MBS的管理者和无人机的运营商可能是不同的利益集团，我们利用契约理论建立了相应的频谱交易问题，其中MBS的管理者必须设计一个最优的契约以使自己的收益最大化。这种合同包括一组带宽选项和相应的价格，每个无人机运营商只从整个合同的所有选项中选择最有利可图的一个。分析推导了基于固定带宽分配的最优定价策略，并在此基础上提出了一种多项式时间内计算最优带宽分配的动态规划算法。通过仿真，我们比较了MBS最优契约与社会最优契约的结果，发现自私的MBS管理者向无人机运营商出售的带宽更少。

英文摘要：
  Unmanned Aerial Vehicle (UAV) has been recognized as a promising way to assist future wireless communications due to its high flexibility of deployment and scheduling. In this paper, we focus on temporarily deployed UAVs that provide downlink data offloading in some regions under a macro base station (MBS). Since the manager of the MBS and the operators of the UAVs could be of different interest groups, we formulate the corresponding spectrum trading problem by means of contract theory, where the manager of the MBS has to design an optimal contract to maximize its own revenue. Such contract comprises a set of bandwidth options and corresponding prices, and each UAV operator only chooses the most profitable one from all the options in the whole contract. We analytically derive the optimal pricing strategy based on fixed bandwidth assignment, and then propose a dynamic programming algorithm to calculate the optimal bandwidth assignment in polynomial time. By simulations, we compare the outcome of the MBS optimal contract with that of a social optimal one, and find that a selfish MBS manager sells less bandwidth to the UAV operators.
