Abstract
Due to the mobility and flexibility of unmanned aerial vehicles (UAVs), the UAV communication networks can effectively support information transmission in the cellular networks. The purpose of this paper is to propose a scheme to ensure the fairness of information transmission for the whole users on the premise of taking into account the quality of service (QoS) of some users in the cellular networks. While considering the QoS of the users, we ensure that information transmission is not monopolized by some users by maximizing the minimum effective capacity of the whole users in the networks. By jointly optimizing user scheduling and UAV’s trajectory, an iterative algorithm based on the block coordinate descent method and successive convex optimization technique is proposed. Numerical analysis results show that our proposed fairness scheme based on the QoS can improve the minimum effective capacity of the users compared with the existing schemes.
