Abstract: To address the ever-growing connectivity demand in communications, the adoption of ingenious solutions, such as utilization of unmanned aerial vehicles (UAVs) as mobile base stations (BSs), is imperative. In general, the location of a UAV base station (UAV-BS) is determined by optimization algorithms, which have high computationally complexities and are hard to run on UAVs due to energy consumption and time constraints. In this paper, we overview the UAV-BS trajectory optimization problem for next generation wireless networks (NGWNs) and show that a convolutional neural network (CNN) model can be trained to infer the location of a UAV-BS in real-time. To this end, we create a framework to determine the UAV-BS locations considering the deployment of mobile users (MUs) to generate labels by using the data obtained from an optimization algorithm. Performance evaluations reveal that once the CNN model is trained with the given labels and locations of MUs, the proposed approach is, indeed, capable of approximating the results given by the adopted optimization algorithm with high fidelity, outperforming reinforcement learning (RL)-based approaches in resource-constrained settings. We also explore future research challenges and highlight key issues. IEEE
