Abstract: Techniques are provided for performing radio frequency (RF) sensing to determine the viewing status of a television user. This can be used to determine user behavior during the playback of content (e.g., whether a user is watching the content), which can be used as a data point for determining the user's level of interest in the content. Using the status of the television user, embodiments can provide additional or alternative functionality, such as powering down and/or powering up the television. Furthermore, RF sensing may be performed by existing television hardware, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a television with little or no added cost.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a wireless station (STA), which may be an example of a virtual reality (VR) device, may receive downlink data or video frames from an access point (AP) for a display at the wireless STA. In some aspects, the wireless STA may detect a motion change of the wireless STA based on employing a motion change detection mechanism and, if the wireless STA detects a motion change, may transmit an indication of the motion change detection to the AP via a feedback message, such as a block acknowledgement (BA) feedback message. The wireless STA, based on detecting the motion change, may additionally transmit a set of inertial measurements of the wireless STA to the AP. The wireless STA may transmit the inertial measurements to the AP via the feedback message or a separate uplink message.

Abstract: Disclosed are systems and techniques for performing mapping using radio frequency (RF) sensing. For instance, a server can obtain a first set of RF sensing data and orientation data corresponding to a first wireless device from a plurality of wireless devices. The first set of RF sensing data can be associated with at least one received waveform that is a reflection of a transmitted waveform from a first reflector. Based on the first set of RF sensing data, orientation data, and location data corresponding to the first wireless device, an indoor map can be generated that includes a reference to the reflector.

Abstract: Techniques are provided for reducing signaling latency in multi-link devices (MLDs). An example method of providing latency sensitive information with a MLD includes receiving downlink data packets from a station via a first radio link, performing radio frequency sensing with a second radio link, detecting a latency sensitive event, and transmitting an indication of the latency sensitive event.

Abstract: Disclosed are systems and techniques for detecting user presence, user motion, and for performing facial authentication. For instance, a wireless device can receive a waveform that is a reflection of a transmitted radio frequency (RF) waveform. Based on RF sensing data associated with the received waveform, the wireless device can determine a presence of a user. In response to determining the presence of the user, the wireless device can initiate facial authentication of the user.

Abstract: Embodiments described herein address these and other issues by providing radio frequency (RF) sensing to determine the status of a driver or other occupant of the vehicle. RF sensing may be provided by existing radios of a vehicle, such a Wi-Fi transceiver, and may therefore provide RF sensing functionality to a vehicle with little added cost. RF sensing can be leveraged to implement safety features such as detecting an unattended child or pet in a vehicle, detecting driver alertness, and the like.
