Abstract: An electronic device may include wireless circuitry having an LC filter. The LC filter may include first and second series inductors coupled between the input and output of the LC filter. An input capacitor can be coupled at the input of the LC filter, and an output capacitor can be coupled at the output of the LC filter. Feedforward capacitors can be cross-coupled with the first and second series inductors to at least partially or fully cancel out any parasitic capacitance associated with the first and second series inductors to mitigate any undesired self-resonant effects associated with the series inductors.

Abstract: To prevent an undesired operating mode of voltage-controlled oscillation (VCO) circuitry from dominating a desired operating mode (e.g., an in-phase operating mode or an out-of-phase operating mode), a supply reset and ramp pulse may be provided to the VCO circuitry when switching to a new mode, such that supply voltage to the VCO circuitry is reset (e.g., set to 0 V or another reference voltage), and gradually increased or ramped up back to a steady-state voltage (e.g., used to maintain a mode) within a time duration. Additionally or alternatively, a switch control bootstrap pulse may be provided to the VCO circuitry that is bootstrapped to (e.g., applied instantaneously or concurrently with) switching the VCO circuitry to the new mode. After a time duration, the VCO circuitry may switch back to a steady-state voltage (e.g., used to maintain the new mode).

Abstract: A power converter circuit included in a computer system regulates a power supply voltage used by other circuits in the computer system. During operation, the power converter circuit monitors the load current, and, in response to a transient in the load current, switches regulation modes to adapt to the new load conditions. Upon a detection of the end of the transient in the load current, the power converter returns to its original regulation mode.

Abstract: Display backing components for head-mounted devices (HMDs) are described that reduce eddy currents in magnetic fields generated by a coil. A HMD may include a coil that is used to generate a magnetic field that may be used to track position of other devices with respect to the HMD. Display backing components, used to provide rigidity, are modified with holes or other gaps to interrupt the path of the eddy currents and reduce the interference with the magnetic field, thus improving the power efficiency of the coil and of the HMD. These modifications may be formed by casting, drilling, cutting or otherwise perforating the display backing during manufacture.

Abstract: Improved positioning resolution and latency may be achieved via physical layer signaling between a mobile device (UE) and a base station. The physical layer procedures may aid target UEs in enhancing their positioning accuracy and latency, and/or reducing network overhead while boosting UE power efficiency. Accordingly, a UE may transmit, via physical layer signaling to a base station, a request for positioning-resources, for example in response to a determination that current positioning-resources of the UE need to be adjusted. The UE may in turn receive, via physical layer signaling from the base station, an indication of adjusted positioning-resources, and may optionally receive an indication of corresponding allocated grant-resources.

Abstract: Apparatuses, systems, and methods for tracking and/or controlling unmanned aerial vehicles (UAVs) as well as tracking UAV controllers (UACs) within a cellular network. A UAV/UAC may provide a cellular network with tracking information such as speed, orientation, altitude, C2 communication quality, C2 communication mode change request, measurement report, RRC status, cell ID, TAC ID, current location of the UAV, and destination of the UAV. The network may forward this information to an unmanned aerial system (UAS) traffic management system (UTM). The UTM may determine, based in part on the tracking information, whether to transfer control of the UAV from the UAC to the UTM. In some embodiments, the UAV/UAC may trigger the UTM to transfer control of the UAV form the UAC to the UTM.

The optical correction structure may increase light in-coupling between the monocentric lens and fiber bundle by reducing or eliminating light reflection at the curved face of the fiber bundle.

Abstract: Embodiments disclosed herein relate to a low-voltage dropout regulator and more specifically to improving a power supply rejection ratio (PSRR) of the low dropout voltage regulator. The low dropout voltage regulator may be used to generate various voltages for integrated circuits of an electronic device. In some cases, a P-type metal-oxide-semiconductor (PMOS) low dropout (LDO) voltage regulator may be used. However, the PMOS LDO may not provide a sufficient PSRR or reduction in supply noise. To address these issues, an N-type metal-oxide-semiconductor (NMOS) LDO voltage regulator having an NMOS pass transistor may be used. The NMOS LDO may provide a lower impedance than the PMOS LDO. Further, the NMOS LDO may provide an increased bandwidth and consume a smaller physical area than the PMOS LDO.

Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may receive a physical downlink control channel (PDCCH) that schedules a physical downlink shared channel (PDSCH) in a slot, and on a component carrier (CC) of a plurality of CCs. The PDCCH may include a total downlink assignment index (DAI) and a counter DAI for hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback of the PDSCH. The total DAI may indicate a total number of pairs of CCs and slots for the HARQ-ACK feedback. The UE may encode the HARQ-ACK feedback to include a bit that indicates whether the PDSCH is successfully decoded. A size of the HARQ-ACK feedback may be based on the total DAI, and a position of the bit may be based on the counter DAI.
