Electronic device for determining location of external electronic device, and operation method of electronic device

An electronic device comprising:

• a communication circuit configured to perform data transmission and/or reception via an ultra-wide band (UWB);
• and
• at least one processor,
• wherein the at least one processor, individually and/or collectively, is configured to:
• determine a first distance between the electronic device and an external electronic device based on first signals exchanged between the external electronic device and the electronic device while the electronic device operates in two-way ranging mode;
• switch from the two-way ranging mode to a one-way ranging mode in response to determining the first distance between the electronic device and the external electronic device;
• receive, from the external electronic device, second signals while the electronic device operates in the one-way ranging mode for determining an amount of change of distance between the electronic device and the external electronic device;
• determine a second distance between the electronic device and the external electronic device based on the first distance and the amount of change of the distance;
• and
• switch from the one-way ranging mode to the two-way ranging mode in response to determining that a specified condition related to distance between the electronic device and the external electronic device is satisfied.
