Abstract: A zero static loadline switching regulator can include a controller having an integrating outer control loop that receives a first feedback signal corresponding regulator load and a reference signal and generates an intermediate feedback signal therefrom. The control circuit can also include an inner control loop that receives the intermediate feedback signal and a second feedback signal corresponding to a load on the regulator and generates an error signal used to control switching devices of the regulator. The control circuit can also include a transient response circuit configured to boost the error signal, for a predetermined time period after and responsive to a load transient. The error signal may be boosted to an intermediate value between its saturation level and its full scale level. The intermediate value may be predetermined or may be determined responsive to the magnitude of the load transient.

Abstract: Apparatuses, systems, and methods to dynamically indicate preference for self-contained slots and slot duration by a user equipment device (UE) in communication with a base station (e.g., a gNB) using a 5G NR radio access technology. A UE may determine to send an indication to a gNB indicating a preference for self-contained slots and slot duration for downlink and/or uplink communications utilizing one or more of the physical downlink control channel (PDCCH), the physical downlink shared channel (PDSCH), and/or acknowledgement messaging (ACK/NACK) for downlink communications, and utilizing one or more of the physical uplink control channel (PUCCH), the PDCCH, and/or the physical uplink shared channel (PUSCH) for uplink communications. The configuration of self-contained slots and slot duration for uplink and/or downlink may be based on one or more of average packet size, average packet rate, traffic type and UE processing capabilities.

Abstract: Adaptive multiplexing and transmit/receive diversity. A wireless device may include multiple antennas. A first set of antennas may be used for communication. One or more trigger conditions may be determined, and additional antennas may be activated for measurement. Based on the measurement(s), a second set of antennas may be selected and used for communication.

Abstract: This disclosure relates to techniques for supporting narrowband device-to-device wireless communication, including possible techniques for providing synchronization sequences. A first wireless device may transmit a preamble of a device-to-device wireless communication with a second wireless device. The preamble may include a first synchronization sequence. The first synchronization sequence may include multiple repetitions of a basis sequence, multiplied by a cover code. The basis sequence may span multiple orthogonal frequency division multiplexing symbols.

Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling. The adjustments may change a particular content item and/or an environment in which it is presented.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may render different content layers that present different classes of content. The different classes of content may have different characteristics. As an example, a first class of content may be static content whereas a second class of content may be dynamic content. The different characteristics of each class of content may be leveraged to use a hybrid approach for content processing. The hybrid content processing may take advantage of different layers needing to be updated at different frequencies and may take advantage of sparse content in some of the layers.

Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.
