The use of Millimeter-wave (mmWave) spectrum in cellular communications has\nrecently attracted growing interest to support the expected massive increase in\ntraffic demands. However, the high path-loss at mmWave frequencies poses severe\nchallenges. In this paper, we analyze the potential coverage gains of using\nunmanned aerial vehicles (UAVs), as hovering relays, in integrated access and\nbackhaul (IAB) mmWave cellular scenarios. Specifically, we utilize the WinProp\nsoftware package, which employs ray tracing methodology, to study the\npropagation characteristics of outdoor mmWave channels at 30 and 60 GHz\nfrequency bands in a Manhattan-like environment. In doing so, we propose the\nimplementation of amplify-and-forward (AF) and decode-and-forward (DF) relaying\nmechanisms in the WinProp software. We show how the 3D deployment of UAVs can\nbe defined based on the coverage ray tracing maps at access and backhaul links.\nFurthermore, we propose an adaptive UAV transmission power for the AF relaying.\nWe demonstrate, with the aid of ray tracing simulations, the performance gains\nof the proposed relaying modes in terms of downlink coverage, and the received\nsignal to interference and noise ratio (SINR).\n
