Title:
DEVICE AND METHOD FOR IDENTIFYING STATUS OF EXTERNAL ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/013549
Kind Code:
A1
Abstract:
An electronic device for identifying a wireless communication device, according to various embodiments of the present invention, may comprise an antenna configured to receive wireless signals output from a first antenna and a second antenna included in an external electronic device, a communication circuit electrically connected to the antenna, and a control circuit. The control circuit may be configured to: control the external electronic device such that the external electronic device outputs designated wireless signals at a first designated phase by using the first antenna and at a second designated phase by using the second antenna; receive the designated wireless signals by using the antenna; identify a signal intensity corresponding to the designated wireless signals by using the communication circuit; and determine a status related to the external electronic device at least on the basis of a difference value between the designated signal intensity and a reference signal intensity. An electronic device for identifying a status of a wireless communication device, according to various embodiments of the present invention, may comprise an antenna configured to receive wireless signals output from a first antenna and a second antenna included in an external electronic device, a communication circuit electrically connected to the antenna, and a control circuit. The control circuit may be configured to: control the external electronic device such that the external electronic device outputs a first wireless signal at a first designated phase by using the first antenna and at the first designated phase by using the second antenna; control the external electronic device such that the external electronic device outputs a second signal at the first designated phase by using the first antenna and at a second designated phase by using the second antenna; receive the first wireless signal and the second wireless signal by using the antenna; identify, by using the communication circuit, a first signal intensity corresponding to the first wireless signal and a second signal intensity corresponding to the second wireless signal; and determine a status related to the external electronic device at least on the basis of a difference value between the first signal intensity and the second signal intensity.
