Thanks to the recent advancements in drone technology, it has become viable\nand cost-effective to quickly deploy small cells in areas of urgent needs by\nusing a drone as a cellular base station. In this paper, we explore the benefit\nof dynamically repositioning the drone base station in the air to reduce the\ndistance between the BS and the mobile user equipment, thereby improving the\nspectral efficiency of the small cell. In particular, we propose algorithms to\nautonomously control the repositioning of the drone in response to users\nactivities and movements. We demonstrate that, compared to a drone hovering at\na fixed location, dynamic repositioning of the drone moving with high speed can\nincrease spectral efficiency by 15 %. However, considering the tradeoff between\nspectral efficiency and energy efficiency of the drone, we show that 10.5 %\nspectral efficiency gain can be obtained without negatively affecting energy\nconsumption of the drone.\n
