Abstract: A method includes obtaining channel information, range information, and angle of arrival (AoA) information based on wireless signals communicated between an electronic device and an external electronic device. The method also includes generating an initial prediction of a presence of the external electronic device relative to a field of view (FoV) of the electronic device based on the channel information and at least one of the range information or the AoA information. The initial prediction includes an indication of whether the external electronic device is within the FoV or outside the FoV of the electronic device. The method further includes performing, using a tracking filter, a smoothing operation on the range information and the AoA information. Additionally, the method includes determining that the external electronic device is within the FoV of the electronic device based on the AoA information, the smoothed AoA information, and the initial prediction.

Abstract: A method and an electronic device for ranging are provided. An ultra-wideband (UWB) signal is received from an external device through a first antenna. A communication state between the external device and the electronic device is identified using information about communication quality included in the UWB signal. A signal received through a second antenna is identified by decoding the received signal based on the identified communication state. A distance between the electronic device and the external device is determined based on whether the received signal is a low frequency (LF) signal.
