Electronic device for performing ranging and method thereof

A ranging method of an electronic device, the ranging method comprising:

• receiving a ultra-wideband (UWB) signal from an external device through a first antenna;
• identifying a communication state between the external device and the electronic device using information about communication quality included in the UWB signal;
• identifying a signal received through a second antenna by decoding the received signal based on the identified communication state;
• and
• determining a distance between the electronic device and the external device based on whether the received signal is a low frequency (LF) signal.

An electronic device comprising:

• a first antenna;
• a second antenna;
• a communication module configured to transmit and receive ultra-wideband (UWB) signals using the first antenna;
• a power transceiver module configured to transmit and receive signals related to charging of the electronic device and low frequency (LF) signals using the second antenna;
• and
• a processor operatively connected to the communication module, the power transceiver module, the first antenna, and the second antenna,
• wherein the communication module is configured to:
• receive an UWB signal from an external device through the first antenna;
• identify a communication state between the external device and the electronic device using information about communication quality included in the UWB signal;
• identify that the power transceiver module receives an LF signal from the external device by decoding a signal received at the power transceiver module through the second antenna, when the communication state is a non-line of sight (NLOS) environment and the information about the communication quality is less than a specified first threshold value,
• determine a distance between the external device and the electronic device by using the UWB signal, when the information about the communication quality is greater than or equal to a specified second threshold value, and
• identify that the electronic device is located inside the external device when the LF signal is identified.
