Abstract: Various embodiments of the present invention relate to an electronic device for controlling communications. The electronic device may comprise: a housing including a first side and a second side facing the first side; a touch screen display exposed through the first side; a wireless communication unit for generating a directional beam in order to establish a wireless communication channel with an external electronic device; a sensor mounted in the housing; at least one processor mounted in the housing and electrically coupled to the display, the wireless communication unit and the sensor; and a memory mounted in the housing and electrically coupled to the at least one processor. The memory according to the various embodiments of the present invention is, when executed, characterized in that the processor is configured to: perform a first direction search for determining the direction of the directional beam corresponding to a first section, wherein the first section falls within a range corresponding to the direction of the electronic device; detect a change in direction of the electronic device by using the wireless communication unit and the sensor; and in response to the change of direction, perform, at least partially, a second direction search corresponding to a second section on the basis of the detected direction change, wherein the second section falls within a range corresponding to the changed direction of the electronic device, and the second section has a smaller range than that of the first section. Other embodiments are possible.

Abstract: An object recognition method and an electronic device thereof are provided. The method includes transmitting a signal to an external object, controlling a wireless communication module to receive a signal reflected from the external object, controlling the wireless communication module to obtain a channel impulse response based on the transmitted signal and the received signal, obtaining information of an orientation of the external object based on the received signal, detecting phase noise caused by a movement of the electronic device, extracting a component matching the orientation of the external object from the detected phase noise, and compensating for phase information in the channel impulse response based on the component matching the orientation of the external object.
