1. A method for localizing a target device (TD) by an user device (UD), the method comprising:
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 of the UD, identifying a first electronic device;
transmitting, to the first electronic device, a request for localizing the TD using an out-of-band channel, wherein the out-of-band channel is different from the UWB channel;
receiving, from the first electronic device, location information of the TD on the out-of-band channel, the location information representing a candidate location of the TD in a coordinate system of the first electronic device or a second electronic device; and
identifying a TD location with respect to a coordinate system of the UD based on the candidate location of the TD.
