    Abstract: The present disclosure relates to a technology for controlling an antenna in a wireless communication system. A beam tracking apparatus comprises an antenna unit simultaneously generating a plurality of directional beams, a transceiver including at least one transceiver unit (TXRU) supplying a signal to the antenna unit or receiving a signal from the antenna unit, and a controller controlling beam generation of the antenna unit and TXRU assignment of the transceiver. The controller controls the antenna unit to generate a serving beam, receives a first signal from a target communication device using the serving beam, controls the antenna unit to generate at least one tracking beam oriented in a different direction from the serving beam while maintaining the serving beam, receives a second signal from the target communication device using the serving beam and the at least one tracking beam, and determines whether to change the serving beam based on the received first and second signals.
