Abstract
The high-altitude and mobility characteristics of unmanned aerial vehicles (UAVs) have made
them a key element of new radio systems, particularly because they can exceed the limits of
terrestrial networks. However, at high altitudes, UAVs can be significantly affected by
intercell interference at a high line-of-sight probability. To mitigate this drawback, we propose
an algorithm that selects the optimal beam to reduce interference and maximize transmission
efficiency. The proposed algorithm comprises two steps: constructing a user-location-based
fingerprint database according to the user types presented herein and cooperative beam
selection. Simulations were conducted using cellular cooperative downlink systems for
analyzing the performance of the proposed method, and the signal-to-interference-plus-noise
cumulative distribution function and spectral efficiency cumulative distribution function were
used as performance analysis indicators. Simulation results showed that the proposed
algorithm could reduce the effect of interference and increase the performance of the desired
signal. Moreover, the algorithm could efficiently reduce overheads and system cost by
reducing the amount of resources required for information exchange.
