Abstract: A device including an antenna and a control method thereof are provided. In the method, a base station receives, from at least one terminal, a reference signal transmitted through at least one beam based on beam sweeping. Also, the base station calculates an angle between the base station and the at least one terminal transmitting the reference signal by using the received reference signal for each beam, and computes an optimal antenna orientation of a base station antenna of the base station by using the calculated angle. Further, the base station adjusts an orientation of the base station antenna according to the optimal antenna orientation of the base station antenna.
