Abstract: An example method of ultra-wideband (UWB) sensing performed by a wireless communication device, the method comprising determining a first channel impulse response (CIR) estimation of a first frequency channel based on a radio access technology (RAT) session, wherein the RAT is different from UWB. The method also comprises determining a second CIR estimation of a second frequency channel based on a UWB session and determining a third CIR estimation of the first frequency channel based on determining a phase difference between the third CIR estimation and the first CIR estimation. The method further comprises determining a total CIR estimation for a combined frequency channel comprising the first frequency channel and the second frequency channel based on stitching the first CIR estimation, the second CIR estimation, and the third CIR estimation.

Abstract: Methods and systems provide for dynamically presenting at least one attentional element within a communication session. The system presents, to each of a number of participants within a communication session, a user interface (“UI”) for the communication session. The system receives a signal of an event associated with a first participant intending to communicate with a second participant, with the second participant not acknowledging the intended communication. The system determines, after a predefined period of time, that the intended communication from the first user has not been acknowledged by the second user and that the event has not yet terminated. The system then initiates an attentional element within the UI of the second participant, the attentional element being more pronounced than the notification.

Abstract: In some implementations, a server may send a request to a first wireless device for capability information, wherein the first wireless device is capable of transmitting both cellular and ultra-wideband (UWB) wireless signals. The server may receive a response from the first wireless device, the response comprising the capability information regarding a capability of the first wireless device for performing UWB positioning. The server may determine first UWB assistance data for the first wireless device based at least in part on (i) the capability information and (ii) information regarding one or more positioning signals transmitted in a cellular wireless network, wherein the first UWB assistance data comprises one or more parameters for a first set of one or more UWB positioning sessions between the first wireless device and a second wireless device. The server may send the first UWB assistance data from the server to the first wireless device.

Abstract: The relative position of a user equipment (UE) within a vehicle is determined using angular measurements, such as angle of arrival (AOA), and optionally ranging measurements, with respect to a number of wireless transceivers within the vehicle using wideband signals. The relative position of the UE with respect to a personal zone or the steering wheel may be determined based on known positions of the wireless transceivers. If the UE is determined to be within the personal zone, at least one functionality of the UE is restricted to avoid driver distraction and, optionally, the operation autonomous driving of the vehicle adjusted. If the UE is worn on the driver's wrist the relative position of the UE with respect to the steering wheel may be similarly determined and operation of the vehicle modified if the UE is determined to be outside a threshold distance from the steering wheel.

Abstract: Techniques for command determination for virtual meetings using gaze and hand gestures are disclosed. In an example method, a client device initiates a virtual meeting to which a number of client devices are connected. The virtual meeting is configured with a designation of a user of the client device as either a hearing-impaired user or a sign language interpreter. The client device determines an indication of a command using a determined command mode based on a first video stream captured by a first camera and a second video stream captured by a second camera, the first and second cameras communicatively coupled to the client device. The client device updates one or more configurations of the virtual meeting based on the indication of the command.
