Learning in the Sky: Towards Efficient 3D Placement of UAVs

Abstract: Deployment of unmanned aerial vehicles (UAVs) as aerial base stations can deliver a fast and flexible solution for serving varying traffic demand. In order to adequately benefit of UAVs deployment, their efficient placement is of utmost importance, and requires to intelligently adapt to the environment changes. In this paper, we propose a learning-based mechanism for the three-dimensional deployment of UAVs assisting terrestrial cellular networks in the downlink. The problem is modeled as a noncooperative game… Show more

“…To improve the throughput in overloaded and outage situations, an RL-based ABS 3D deployment approach was proposed in [17], where UAVs found their optimal location to increase system performance gain. Similarly, 3D ABS deployment was presented in [18] to maximize users' coverage by finding ABS optimal altitude and location using a bisection search algorithm.…”

“…The high propagation delay of satellite systems are the major barrier in using them for uRLLC purpose, however, the UAVs can still remarkably contribute into this aspect of 5G use cases too. For such purposes, UAVs acting as aerial BSs (see Figure (1d)) are flexible platforms that can adjust their 3D locations and employ 5G communication technologies to serve the target users [57], [58]. Finally, [7] provides an overview of the 3GPP NTN features, uncovering their potential to satisfy consumer expectations in 5G networks.…”

“…In [13], the coverage area for UAVs in the presence of co-channel interference was maximized. In [14], a set of UAVs were deployed to assist a macro BS (MBS) in downlink for overload situations. To solve the problem in a distributed manner, reinforcement learning algorithms were proposed.…”
