Samsung patents method to locate devices using UWB and Bluetooth signals

1. An electronic device comprising: a communication circuit; 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, an advertising frame transmitted by a first external electronic device; transmit, via the communication circuit, 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; generate a plurality of ranging blocks for performing ranging, wherein the plurality of ranging blocks includes a first ranging block and a second ranging block; obtain 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; obtain 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; obtain, via the communication circuit, 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; identify 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.
