Three-Dimensional Spectrum Occupancy Measurement Using UAV: Performance Analysis and Algorithm Design

Spectrum sharing, as an approach to significantly improve spectrum efficiency in the era of 6th generation mobile networks (6G), has attracted extensive attention. Radio Environment Map (REM) based low-complexity sharing is widely studied where occupancy measurement (SOM) vital construct REM. The SOM three-dimensional (3D) space becoming increasingly essential support with space-air-ground integrated network being a great momentum 6G. In this paper, we analyze performance 3D further study tradeoff between accuracy and SOM. We discover that error related area boundary surfaces licensed networks, number discretized cubes, length edge space. Moreover, design fast accurate algorithm utilizes unmanned aerial vehicle (UAV) measure considering path planning UAV, which improves by requiring less time flight UAV for satisfactory performance. theoretical results obtained paper reveal dependencies describe methodology, proposed beneficial It noted may provide guideline more areas such monitoring, measurement, planning, etc.
