Abstract: A method for localizing a target device (TD) by a user device (UD) includes determining whether the TD is within a range and within a field-of-view (FoV) of the UD based on a UWB channel between the TD and the UD. In response to a determination that the TD is outside the range and not within the FoV, the method includes identifying a first electronic device. The method also includes transmitting, to the first electronic device, a request for localizing the TD using an out-of-band channel. The method further includes receiving, from the first electronic device, location information of the TD on the out-of-band channel. The location information represents a candidate location of the TD in a coordinate system of the first or a second electronic device. Additionally, the method includes identifying a TD location with respect to a coordinate system of the UD based on the candidate location.

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.
