Positioning method using wireless communication, and electronic device for supporting same

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

• receiving an advertising frame transmitted by a first external electronic device;
• transmitting a first request signal, requesting a second external electronic device to receive the advertising frame from the first external electronic device, to the second external electronic device in response to receiving the advertising frame from the first external electronic device;
• generating a plurality of ranging blocks for performing ranging, wherein the plurality of ranging blocks includes a first ranging block and a second ranging block;
• obtaining first location data including a location of the second external electronic device with respect to the electronic device for a time duration in which the first ranging block is enabled, based on performing the ranging with the second external electronic device;
• obtaining second location data including the location of the second external electronic device with respect to the electronic device for a time duration in which the second ranging block is enabled, based on performing the ranging with the second external electronic device;
• receiving response data, including first timestamp information on a timing at which the second external electronic device receives the advertising frame transmitted by the first external electronic device and second timestamp information on a timing at which the second external electronic device receives a second message corresponding to a ranging response message from the electronic device, from the second external electronic device;
• identifying a location of the first external electronic device with respect to the electronic device by selecting one of the first location data or the second location data as selected location data for the second external electronic device based on which of the first ranging block or the second ranging block a timing corresponding to the first timestamp information is temporally closer to;
• calculating a difference between (i) a distance from the first external electronic device to the electronic device and (ii) a distance from the first external electronic device to the second external electronic device, based on the first timestamp information, the second timestamp information, and the selected location data;
• and
• determining a location of the first external electronic device based on the difference and the selected location data.

An electronic device comprising:

• a communication circuit supporting ultra-wideband (UWB) communication;
• memory storing instructions;
• and
• at least one processor comprising processing circuitry,
• wherein the instructions, when executed by the at least one processor individually and/or collectively, cause the electronic device to:
• receive, via the communication circuit, from a first external electronic device, a first request signal requesting the electronic device to receive an advertising frame transmitted by a second external electronic device,
• generate an advertisement reception session in response to receiving the first request signal,
• generate a plurality of ranging blocks for performing ranging with the first external electronic device, wherein the plurality of ranging blocks includes a first ranging block and a second ranging block,
• perform the ranging using UWB communication with the first external electronic device during a time duration in which the first ranging block is enabled and during a time duration in which the second ranging block is enabled,
• receive, via the communication circuit, the advertising frame transmitted by the second external electronic device through the advertisement reception session, and
• transmit, via the communication circuit, response data including first timestamp information on a timing at which the advertising frame is received from the second external electronic device and second timestamp information on a timing at which the electronic device receives a second message corresponding to a ranging response message from the first external electronic device, to the first external electronic device.
