Abstract: An electronic device for gesture recognition, includes a processor operably connected to a transceiver. The transceiver is configured to transmit and receive signals for measuring range and speed. The processor is configured to transmit the signals, via the transceiver. in response to a determination that a triggering event occurred, the processor is configured to track movement of an object relative to the electronic device within a region of interest based on reflections of the signals received by the transceiver to identify range measurements and speed measurements associated with the object. The processor is also configured to identify features from the reflected signals, based on at least one of the range measurements and the speed measurements. The processor is further configured to identify a gesture based in part on the features from the reflected signals. Additionally, the processor is configured to perform an action indicated by the gesture.

Abstract: A method includes receiving from a transceiver, at a processor of an electronic device, a radar signal, the radar signal including a set of signal strength values across a range of Doppler frequency shift values and a range of time values. The method further includes extracting a time series of frequency features from the radar signal, wherein frequency features of the time series of frequency features include a determined Doppler frequency shift value for each time value of the range of time values, identifying segments within the time series of frequency features, analyzing the segments to determine a start time for a classification engine, at the start time, analyzing, by the classification engine, at least one of a subset of the time series of frequency features or a subset of the radar signal to identify a control gesture, and triggering a control input associated with the control gesture.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for updating a target wake time (TWT) service period and interval. The apparatuses include a communication device comprising a transceiver and a processor. The transceiver is configured to transmit and receive higher layer data packets in a TWT operation during a time period. The processor is configured to determine, based on PHY data rates during the time period, effective higher layer data rates, estimate an initial data transceiving time based on the effective higher layer data rates and total lengths of the data packets, adjust the initial data transceiving time to obtain a higher layer data transceiving time based on an estimated network congestion level, an estimated re-transmission rate, and a total amount of TWT overhead during the time period, and determine a new TWT service period and interval based on the higher layer data transceiving time.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for requesting traffic characteristics in a wireless network. The apparatuses include a wireless station (STA) device comprising a transceiver and a processor operably coupled to the transceiver. The transceiver is configured to transmit and receive signals. The processor is configured to generate a traffic profile request element that comprises an indication of a request for an access point (AP) to provide, to the STA, traffic characteristics, as observed at the AP, of downlink (DL) traffic between the AP and the STA. The transceiver is further configured to transmit to the AP the traffic profile request element. The requested traffic characteristics are used to determine target wake time (TWT) parameters for a TWT operation between the AP and the STA.

Abstract: Methods and electronic devices for target detection and tracking operations are provided. A method of operating an electronic device includes identifying, based on signals received through a radar transceiver of the electronic device, a peak of the received signals in a current time slot, determining whether the peak in the current time slot corresponds to a tracked target based on comparing a location of the peak in the current time slot with a location of a peak corresponding to the tracked target in a previous time slot as a function of a movement speed threshold, and in response to a determination that the peak in the current time slot corresponds to the tracked target, updating tracking information for the tracked target associated with the peak in the current time slot.
