Abstract: An electronic device and a method of the electronic device for performing localization in a wireless communication system are provided. The electronic device and method comprise: receiving, from a plurality of anchor nodes, signals for the localization; performing ranging measurements of the signals based on a range and an angle of arrival (AoA) of the signals; determining whether at least one of the plurality of anchor nodes is not detected based on the ranging measurements; determining, based on a determination that the at least one anchor node is not detected based on the ranging measurements, whether at least one other anchor node in the plurality of anchor nodes is located on a line of sight (LOS) from the electronic device, wherein the LOS is determined based on the AoA of the signals; and performing the localization based on the at least one other anchor node.

Abstract: An electronic device includes a transceiver and a processor. The processor is operably connected to the transceiver. The processor is configured to transmit, via the transceiver, radar signals for activity recognition. The processor is also configured to identify a first set of features and a second set of features from received reflections of the radar signals, the first set of features indicating whether an activity is detected based on power of the received reflections. Based on the first set of features indicating that the activity is detected, the processor is configured to compare one or more of the second set of features to respective thresholds to determine whether a condition is satisfied. After a determination that the condition is satisfied, the processor is configured to perform an action based on a cropped portion of the second set of features.

Abstract: A method for contactless vital sign monitoring includes transmitting, via a transceiver, radar signals for object detection. The method also includes generating a clutter removed channel impulse response from received reflections of the radar signals a portion of which are reflected off of a living object. The method further includes identifying a set of range bins corresponding to a position of the living object. Additionally, the method includes identifying a first set of signal components representing a respiration rate of the living object and a second set of signal components representing a heart rate of the living object.
