    Abstract: In general, to provide acknowledgment information by a first wireless device, the first wireless device sends repeated instances of acknowledgment information in respective first and second frame structures, in response to receipt of first information from a second wireless device. In addition, the first wireless device also sends further acknowledgment information in the second frame structure that is responsive to second information received from the second wireless device.

    Abstract: Aspects of the subject technology relate to electronic device display circuitry and methods of operating the display. The display circuitry includes gate-in-panel (GIP) drivers for each pixel row of a pixel array, and mode selection circuitry coupled between two of the GIP drivers. The mode selection circuitry receives a select signal to switch the display between a full-screen mode of operation and a split-screen mode of operation. The mode selection circuitry allows the pixel rows to be operated in a butterfly driving mode that facilitates reduction of optical artifacts when displaying augmented-reality or virtual-reality content with a multi-function display such as a display of a smartphone or a tablet.

    Abstract: An electronic device may include an electronic display having multiple pixels to display an image based on processed image data. Each of the pixels may include multiple sub-pixels. The electronic device may also include image processing circuitry to receive input image data, in a first color space, having luminance values for each of the sub-pixels. The circuitry may also map the input image data from the first color space to a second color space and apply a multi-dimensional lookup table, based on the input image data in the second color space, to generate compensated image data. The lookup table may receive the luminance values for each of the sub-pixels and output corrected luminance values compensated for an expected amount of current leakage between the sub-pixels. The circuitry may also inversely map the compensated image data from the second color space to the first color space to generate the processed image data.

    Abstract: A mobile station receives a downlink control structure in a first carrier, where the downlink control structure indicates that control information for the mobile station is on a second, different carrier. The mobile station decodes the control information in the second carrier, where the control information specifies resource allocation of a wireless link for the mobile station. More specifically, according to some implementations, the control channel in the first carrier specifies the resource allocation for an extended control channel in the second carrier, where the extended control channel specifies the resource allocation for traffic data of a wireless link for the mobile station.

    Abstract: A display device may include pixels that display image data. The display device may also include a circuit that receives pixel data having a gray level for at least one pixel, such that the pixel data corresponds to a frame of the image data and the frame includes sub-frames. The pixel data causes the circuit to provide at least one current pulse to the at least one pixel according to a first order of the sub-frames. The circuit may also receive a second order of the sub-frames, such that the second order is mapped with respect to the first order, and at least one current pulse is provided to the at least one pixel according to the second order. As such, visual artifacts depicted on the display are reduced.

    Abstract: The present invention is a method and system for supporting a beamforming antenna system in a mobile broadband communication network with an improved beam pattern, beam sweep pattern, pilot channel design with feedback and reporting rules, and control signaling design. Specifically, the improved beam pattern includes a method of supporting wireless communications in a wireless network forming at least two spatial beams within a cell segment where the at least two spatial beams are associated with different power levels, and separately, where at least two spatial beams can be moved across the cell segment according to a unique sweep pattern. The pilot channel design improves network bandwidth performance and improves user mobility tracking. Feedback and reporting rules can be established using a particular field designator, CQI, in the preferred embodiment.
