WIPO Patent Application WO/2021/002647

Kind Code:

A1

Abstract:

Disclosed is an electronic device which includes a first antenna, a second antenna, a communication module, a power transceiver module, and a processor operatively connected to the communication module, the power transceiver module, and the first and second antennas. The communication module may receive the UWB signal from an external device, identify a communication state between the external device and the electronic device by using information about communication quality included in the UWB signal, identify a signal received by the power transceiver module by decoding the received signal based on the identified communication state, and determine a distance between the electronic device and the external device based on that the received signal is the LF signal. In addition, it is possible to implement various embodiments understood through the disclosure.
