1. A method performed by a base station in a wireless communication system, the method comprising:
receiving position information of at least one user equipment (UE);
determining an initial position of an unmanned aerial vehicle (UAV) based on the position information;
transmitting, to the UAV, control information related to the initial position and association information between the at least one UE and the UAV;
receiving, from the UAV, first feature information related to a communication state between the at least one UE and the UAV;
determining a step size b which the UAV moves, based on the first feature information;
obtaining movement direction information of the UAV by applying the first feature information to a reinforced learning network corresponding to the determined step size among a plurality of reinforced learning networks; and
transmitting the movement direction information and information regarding the determined step size to the UAV.
