Abstract

This paper considered a wireless communication network with multiple UAV base stations and multiple users. In the network, due to the limited spectrum resource, the backhaul links of the UAV base stations and the data links of the users shared the same spectrum. In order to use the spectrum resource efficiently and improve the communication performance of the users, this paper jointly optimized the bandwidth and power of the backhaul and data links as well as the flight trajectory of the UAV base stations, to maximize the minimum average rate of all users. This joint optimization was subject to the UAVs' mobility, the total spectrum bandwidth, and the total transmit power, and the involved joint optimization problem was non-convex, thus it was difficult to find the optimal solution. This paper proposed an efficient algorithm to obtain a high-quality suboptimal solution of it. Simulation results show that the minimum user rate achieved by the proposed joint optimization algorithm is significantly higher than that of the benchmark schemes.
