Abstract: An electronic device and a method for gesture recognition are disclosed. The electronic device includes a radar transceiver and a processor operably connected to the radar transceiver. The processor is configured to detect a triggering event. In response to detecting the triggering event, the processor is configured to transmit, via the radar transceiver, radar signals. The processor is also configured to identify a gesture from reflections of the radar signals received by the radar transceiver. The processor is further configured to determine whether the gesture is associated with the triggering event. Based on determining that the gesture is associated with the triggering event, the processor is configured to perform an action indicated by the gesture.

Abstract: A method includes obtaining a set of signal quality measurements. The signal quality measurements correspond to reference signals, respectively, from among a plurality of reference signals received at an electronic device. The method includes determining whether a change in amplitude in the set of signal quality measurements satisfies a temporal condition. The method includes in response to a determination that the change in amplitude in the set of signal quality measurements satisfies the temporal condition, triggering the electronic device to perform radar operations to determine whether a location of an object in proximity to the electronic device satisfies a proximity condition. The method includes in response to a determination that the location of the object satisfies the proximity condition, changing a transmission parameter of uplink wireless signals to satisfy a maximum permissible exposure (MPE) of the object to radio frequency energy.

Abstract: Embodiments of the present disclosure provide methods and apparatuses for balancing a tradeoff between channel utilization and fairness during restricted target wake time (TWT) operation 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 latency-sensitive uplink traffic and receive latency-sensitive downlink traffic in a restricted TWT service period (SP) during restricted TWT operation, and to receive, from an access point (AP), an indication that the restricted TWT SP is terminated early based on a lack of latency-sensitive uplink traffic for transmission by the STA and a lack of latency-sensitive downlink traffic for reception by the STA in a remainder of the restricted TWT SP. The processor is configured to terminate operation of the restricted TWT SP by the STA.
