Abstract: This disclosure relates to techniques for detecting a signal and powering off at least some receiver components if no signal is detected. A wireless device may take one or more measurements of one or more signals. The wireless device may determine, based on the measurements, whether a signal (e.g., a signal of a licensed assisted access cell) is anticipated during an upcoming time period, e.g., a subframe or portion of a subframe. If no signal is anticipated, the wireless device may power off at least some receiver functions.

Abstract: Apparatuses, systems, and methods for a wireless device to perform user equipment (UE) initiated beam management procedures with a base station or gNB. A wireless device in communication with a 5G base station may detect degradation in the pair of transmit and receive beams between the gNB and the device. The device may select a preferred beam management procedure and indicate the preference to the gNB.

Abstract: This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

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: A method performed by a user equipment (UE) connected to a network that utilizes a first bandwidth for a plurality of network operations and assigns the UE a second bandwidth, within the first bandwidth, to utilize for communication with the network. The method including determining a third bandwidth within the first bandwidth that is narrower than the first bandwidth and wider than the second bandwidth and includes the second bandwidth, monitoring the third bandwidth for at least one reference signal transmitted by the network, and determining at least one value that corresponds to the connection between the UE and the network based on the at least one reference signal.

Abstract: This disclosure relates to techniques for wireless devices to improve wireless communication technology coexistence characteristics using narrow band use awareness in a wireless communication system. A wireless device may attach to a serving cell according to a first radio access technology. A frequency range in active use by the wireless device for communication according to the first radio access technology may be determined. The frequency range may include less bandwidth than the system bandwidth of the serving cell. An indication of the frequency range may be provided from a portion of the wireless device implementing the first radio access technology to a portion of the wireless device implementing a second radio access technology. It may be determined whether to modify operation of the wireless device with respect to the second radio access technology based at least in part on the indication of the frequency range.

Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. Crosstalk between viewing zones and disparity between images received from different viewing zones may result in disparity-caused shifts in images perceived by viewer of the lenticular display. To mitigate these disparity-caused shifts, compensation circuitry may be included in the display pipeline circuitry. The compensation circuitry may include stored disparity-caused shift calibration information that is used for the compensation. The stored disparity-caused shift calibration information may be a polynomial function that outputs a magnitude of disparity-caused shift for a given pixel location.

Abstract: An electronic device uses a multidimensional (e.g., 3D) scaler to process multiple-viewing-angle (e.g., 3D-aware) images by resampling each view image and processing image data of each view image according to a view map to change resolution or improve perceived image quality. After being processed, each view image of the multiple-viewing-angle image is used to rebuild a final processed multiple-viewing-angle (e.g., 3D-aware image) with all views for displaying on the electronic device.

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.
