Abstract: Aspects presented herein may improve the performance of mobile/computer applications. Aspects presented herein may enable mobile/computer applications to differentiate entities that are associated with UEs or entities running the navigations applications, thereby enabling the mobile/computer applications (or their associated servers) to have a more accurate understanding of the conditions surrounding the UEs and their users. In one aspect, a network node obtains first information including at least one feature associated with a plurality of devices. The network node selects a first subset of the plurality of devices for a measurement based on the at least one feature associated with the plurality of devices (or the network node may exclude a second subset of the plurality of devices from the measurement).

Abstract: Techniques are provided for utilizing wireless devices to detect and classify barriers between devices. An example method performed by a user equipment for authorizing a device-to-device request includes receiving a request from a wireless node, determining a first range measurement to the wireless node using a first positioning technique, determining a second range measurement to the wireless node using a second positioning technique that is different from the first positioning technique, and allowing or denying the request based on the first range measurement and the second range measurement.

Abstract: Differing operations of a wireless communication device benefit from different antenna configurations, such as for positioning, where closely spaced antennas are desirable, and data communication, where antenna diversity is desirable. A device is configured to receive a request for receive a request for determining a position of a user equipment (UE), select one of a first plurality of antennas or a second plurality of antennas for determining the position of the UE, receive wireless signals using the selected first plurality of antennas or the second plurality of antennas, and determine the position of the UE based at least in part on the received wireless signals.

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: A mobile device is disclosed. The mobile device may receive one or more wireless local area network (WLAN) signals. The mobile device may determine Channel State Information (CSI) data from the one or more WLAN signals. The mobile device may determine one or more environmental characteristics associated with an environment of the mobile device based on the CSI data. The mobile device may send information indicative of the one or more environmental characteristics to a location server (LS), or determine a position of the mobile device based at least in part on the one or more environmental characteristics, or any combination thereof.

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: Disclosed herein are techniques for range measurement between one or more wireless stations (STAs) and a first access point (AP). In various embodiments, the first AP may synchronize a clock of the first AP with clocks of one or more synchronized APs. The first AP may perform a synchronization session with the one or more STAs. The first AP may also transmit one or more Broadcast time-of-departure (TOD) frames to the one or more STAs. Each of the one or more Broadcast TOD frames may include a time of departure of a Broadcast TOD frame from the first AP. A second AP and a third AP of the one or more synchronized APs may also transmit one or more Broadcast TOD frames to the one or more STAs for range and/or position determination.

Abstract: Techniques for determining a device location based on measurements from multiple RATs are described. In an aspect, the methods and apparatus include determining, at a first device, one or more round trip time (RTT) measurements based on one or more signals communicated with a second device over a first Radio Access Technology (RAT). Further, in an aspect, the methods and apparatus include determining, at the first device, one or more angle measurements based on one or more signals communicated with the second device over a second RAT. Additionally, the methods and apparatus include determining a location of the first device in relation to the second device based on the one or more RTT measurements and the one or more angle measurements. The one or more angle measurements may include one or more angle of departure (AoD) measurements, one or more angle of arrival (AoA) measurements, or both.
