The method may further comprise determining an identity of the person based at least in part on an observed gait of the person and an observed shape of the person, wherein the observed gait of the person and the observed shape of the person are determined based at least in part on the CSI data. The method may further comprise outputting an indication of the determined identity of the person.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit an indication of a media access control (MAC) address associated with an access point to a group of access points included in a network. The network node may receive single-sided round-trip-time (RTT) data associated with a user device associated with the access point, wherein the single-sided RTT data is received from each of the group of access points based at least in part on transmitting the indication of the MAC address to the group of access points. The network node may determine a location of the user device based at least in part on the single-sided RTT data. The network node may transmit an indication of the location of the user device to the access point. Numerous other aspects are described.

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: Disclosed are systems and techniques for extended reality optimizations using radio frequency (RF) sensing. An example method can include obtaining RF sensing data; determining, based on the RF sensing data, reflected paths of one or more reflected RF signals, each reflected RF signal including a reflection of a transmitted signal from one or more objects in physical space; comparing the one or more reflected paths, to a field-of-view (FOV) of an image sensor of the device; and based on the comparison, triggering an action by the device and/or the image sensor.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for initiating a secure FTM session between at least first and second STAs. A first STA initiates, with a second STA, a secure FTM session. The first STA receives a plurality of FTM packets from the second STA, each of the plurality of FTM packets including at least one preamble subject to a respective first CSD. The first STA transmits, to the second STA, an ACK for each of plurality of FTM packets. The first STA receives a measurement report including a ToD offset by the respective first CSD for each of the plurality of FTM packets, and a ToA at the second STA of each of a plurality of ACKs. The first STA determines a RTT between the first and second STAs based on the offset ToD and the ToA.

Abstract: Motion detection services are performed in a wireless network (e.g., a cellular network) with reference to beamforming. Reference signals or other resources for motion detection based on RAdio Detection And Ranging (RADAR) are transmitted over one or more transmit beams or received over one or more receive beams. Any motion measured from reflections of the signals may be associated with one or more of the transmit or receive beams. A device configured to receive the reflections determines one or more motion measurements associated with one or more beams, and determines one or more motion state metrics associated with the one or more beams. The one or more motion state metrics are included in one or more motion state reports to a network entity (e.g., a radar server), which may be used for various operations in the wireless network.
