    Abstract: Systems, methods, and circuitries are provided for performing adaptive cell searching. In one example, a method for a user equipment (UE) includes determining that the UE has entered an out of coverage (OOC) status and, in response, configuring a cell search pattern that defines a series of scheduled search instances for each of one or more frequency sets. A timing of the series of scheduled search instances is based on a time at which the UE entered OOC status and the cell search pattern is configured to cause performance of a respective minimum search rate of respective frequency sets. The frequency sets are searched based on the configured cell search pattern.

    Abstract: Techniques are described for multi-layer interference detection. The method can include transmitting data to a system using a connection on a wireless network, the system configured to provide access to a functionality of a device. The method can further include accessing at least one of link quality monitoring (LQM) information from a medium access control layer of the user device or transmission control protocol (TCP) information from a transport layer of the device during a presentation of data by the system. The method can further include determining that the wireless network is experiencing interference based at least in part on the LQM information or TCP information. The method can further include generating interference information based at least in part on determining that the wireless network is experiencing the interference. The method can further include transmitting the interference information to the system during the presentation of data by the system.

    Abstract: A video encoding system is configured to determine, based on image data, a distortion metric for a prediction mode candidate based on 1) gradient similarity between a prediction block of the image data and a reconstructed prediction block of reconstructed image data generated based on the image data and 2) motion between two frames of the image data. The video encoding system is also configured to select, from a plurality of prediction mode candidates, the prediction mode candidate as a prediction mode based at least in part on the distortion metric. Additionally, the video encoding system is configured to encode the image data based on the prediction mode.

    Abstract: An electronic device includes memory and motion compensated temporal filtering (MCTF) circuitry communicatively coupled to the memory. The MCTF circuitry is configured to receive a plurality of motion vectors. The MCTF circuitry is also configured to retrieve a plurality of source pixel values and a plurality of reference pixel values from the memory. The plurality of source pixel values and the plurality of reference pixel values correspond to the plurality of motion vectors. The MCTF circuitry is further configured to determine motion vector edge statistics based on the plurality of motion vectors. The MCTF circuitry is further configured to generate a plurality of filtered pixel values by filtering the plurality of source pixel values based on the plurality of reference pixel values and the motion vector edge statistics.

    Abstract: A phase shifter circuit may include a multiple phase shifter cells (or cells) to selectively shift a phase of an input signal by a desired phase shift value. For example, each of the phase shifter cells may shift the phase of the input signal by a positive fractional phase shift value or a negative fractional phase shift value. The phase shifter cells may include circuitry to form an inductor-capacitor circuit to provide the negative fractional phase shift value and form a capacitor-inductor circuit to provide the positive fractional phase shift value. The phase shifter cells may receive control signals to form the inductor-capacitor circuit and the capacitor-inductor circuit. An electronic device may include multiple phase shifter circuits to adjust a phase of transmission signals and/or reception signals of phased array antennas.

    Abstract: Phase reassignment among power converters is disclosed. Multi-phase power converters of a plurality are arranged such that the various phases of each can be shared. When a given power converter has a high demand current and a phase of another power converter in the same group is currently unused, that phase may be borrowed by the given power converter to meet the demand current. The power converter that borrows a phase from another power converter is designated as the leader, while the borrowed phase is designated as a follower. The regulated supply voltage is determined by the leader power converter, irrespective of the regulated output voltage to be generated by the power converter from which another phase is borrowed.
