An operation method of an unmanned aerial vehicle terminal. The unmanned aerial vehicle terminal generates a beam table by using first information on a plurality of beams transmitted by a first transmission point. The unmanned aerial vehicle terminal monitors whether conditions for beam switching are satisfied. The unmanned aerial vehicle terminal determines a target location based on the beam table when the conditions for the beam switching are satisfied. The unmanned aerial vehicle terminal moves to the target location. In addition, the unmanned aerial vehicle terminal updates the beam table depending on whether beam table update conditions are satisfied.
