Abstract: A user equipment including a transceiver and a processor is configured to receive, from a base station and via the transceiver, a set of resource indicators identifying a set of beams and a configuration for reporting a duty cycle for transmission in an uplink direction for at least one resource indicator of the set of resource indicators. The processor is also configured to, at least one of periodically or based on an event reported by a body proximity sensor (BPS), determine the duty cycle for transmission in the uplink direction for the at least one resource indicator of the set of resource indicators; and transmit, to the base station via using the transceiver, the determined duty cycle and the corresponding at least one resource indicator of the set of resource indicators according to the received configuration for reporting the duty cycle.

Abstract: This disclosure relates to methods for providing detailed basic service set load information in a wireless local area network. A wireless device may receive basic service set load information including one or more of overlapping basic service set channel utilization information, in basic service set channel utilization information for a basic service set, or load history information for the basic service set. The wireless device may select a basic service set with which to associate based at least in part on the load information for the basic service set.

Abstract: Some aspects of this disclosure include a system, apparatus, article of manufacture, method, and/or computer program product and/or combinations and/or sub-combinations thereof, for implementing multi-credential mapping mechanisms in wireless communication networks, such as a wireless local area network (WLAN). The multi-credential mapping mechanisms can use pointer schemes for communicating multiple credentials (e.g., Authentication and Key Managements (AKMs) and ciphers) in the wireless communication networks. The multi-credential mapping mechanisms can reduce congestion in the communication medium and improve the communications between an access point (AP) and stations (STAs).

Abstract: Some examples of the disclosure are directed to systems and methods for augmenting and/or minimizing environment audio based on video characteristics associated with a video communication session facilitated by a video communications application. The video characteristics include activation of an outward facing camera. In response to detecting the activation of an outward facing camera, an electronic device augments an environment audio stream associated with the video communication session and attenuates a first person audio stream associated with the video communication session such that the user listening to the audio stream hears audio that has the environmental audio emphasized while the first person audio is deemphasized. In response to detecting the activation of an inward facing camera, the device emphasizes the first person audio stream and deemphasizes the environmental audio stream.

Abstract: Systems and methods described herein provide shared electronic device operation. In one example, a shared operation configuration for a plurality of users of an electronic device is obtained. A device trigger corresponding to operation of the electronic device is detected. A particular user is identified amongst the plurality of users based on the shared operation configuration. A user device associated with the particular user is identified. An operation alert representing the device trigger is generated, wherein the operation alert is sent to the user device.

Abstract: Embodiments herein provide various apparatuses and techniques to reduce flicker noise and voltage offset from the buffers and/or amplifiers while avoiding additional alias components in a sampled-data receiver with chopper stabilization. Additionally, a direct-conversion baseband chain may be improved by disposing alternating current (AC) coupling circuits between chopper circuits in the transmitter or receiver chain to enable selection of a distinct common-mode level at each stage of the direct-conversion chain, while reducing or eliminating signal loss at direct current (DC) frequencies.

Abstract: This disclosure is directed to a Voltage-Controlled Oscillator (VCO) with improved phase noise compared to other VCOs. The VCO may include a first cell and a second cell separated by common-mode (CM) isolation circuitry to reduce an amplitude of CM noise at an output signal. The CM isolation circuitry may inductively couple the first cell to the second cell for generating the output signal based on a resonant frequency range including resonant frequencies of the CM isolation circuitry, the first cell, and the second cell. As such, the first cell and the second cell may each include a portion of an entirety of the CM noise. In some cases, the portions of the CM noise on the first cell and/or the second cell may improve a signal to noise ratio of the output signal.

Abstract: Embodiments described herein include an optoelectronic sensing device having a vertical cavity surface emitting laser (VCSEL), a resonance cavity photodetector (RCPD), and a tunnel junction. The VCSEL is at least partly defined by a first set of semiconductor layers disposed on a substrate. The first set of semiconductor layers includes a first active region. The VCSEL is configured to emit laser light towards the substrate, upon application of a first bias voltage, and undergo self-mixing interference upon reception of reflections or backscatters thereof. The RCPD is vertically adjacent to the VCSEL and is at least partly defined by a second set of semiconductor layers disposed on the substrate. The second set of semiconductor layers includes a second active region. The RCPD is configured to detect, upon application of a second bias voltage, the self-mixing interference. The tunnel junction is disposed between the first active region and the second active region.
