Abstract: The present disclosure relates to a tree-search based trajectory planning and resource management method and apparatus of an unmanned aerial vehicle base station. The tree-search based trajectory planning and resource management method of an unmanned aerial vehicle base station according to an embodiment of the present disclosure includes: decomposing an optimization problem of trajectory planning, user association (UA), resource allocation (RA), and power control (PC) related to the unmanned aerial vehicle base station into a time axis; managing resources by jointly optimizing variables of the UA, RA, and PC for an arbitrary location of the unmanned aerial vehicle base station; and obtaining the trajectory planning by obtaining position variables based on the obtained predetermined function value and a depth-first search (DFS) algorithm.
