    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 includes obtaining wireless fidelity (Wi-Fi) based channel state information (CSI). The method also includes filtering the CSI to remove radio frequency (RF) interference. The method further includes executing a motion detection module that detects for motion in a space based on whether macro-movements are present in the filtered CSI, and provides an indication that the space is occupied upon detecting motion in the space. The method also includes, in response to the indication that the space is occupied, executing an occupancy detection module that detects whether the space is still occupied based on whether micro-movements and breath signals are present in the filtered CSI, retains the indication that the space is occupied upon detecting that the space is still occupied, and provides an indication that the space is not occupied upon detecting that the space is no longer occupied.

    Abstract: A method for operating an electronic device includes transmitting signals to an external electronic device. The method also includes receiving signals from the external electronic device. The method further includes generating location information of the external electronic device relative to the electronic device based on a differences between the transmitted signals and the received signals. Additionally, the method includes determining an action for changing a state on at least one of the electronic device or the external electronic device based on the location information. In response to determining that the action is associated with the electronic device, the method includes performing the action. In response to determining that the action is associated with the external electronic device, method includes sending an instruction to the external electronic device to perform the action.

    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 for presence detection using ultra-wide band (UWB) radar includes obtaining a set of centroids based on UWB radar measurements. The method includes, for each respective centroid among the set of centroids: classifying the respective centroid as one among human movement and non-human movement, based on a set of features for the respective centroid satisfying a human-movement condition; and when the respective centroid is classified as the human movement, determining a two-dimensional (2D) location of human movement based on the UWB radar measurements. The method includes updating a current state value that indicates whether a human presence is detected inside boundaries of a 3D space, based at least in part on the classification of each of the respective centroids among the set of centroids.
