Abstract: A device and method for power saving between a scheduling request and a grant. A user equipment (UE) establishes a connection to a network, the UE and the network may be configured with a Connected Discontinuous Reception (C-DRX) functionality, the C-DRX functionality including a cycle with at least one onDuration. The UE transmits, during a first subframe a scheduling request (SR) to the network, the SR corresponds to data that is to be transmitted by the UE. The UE determines a second subframe for the UE to enter an active mode of processing for a reception of a grant, the second subframe is subsequent to the first subframe and prior to a next onDuration. The UE initiates an active mode of processing for the reception of the grant during the second subframe.

Abstract: Apparatuses, systems, and methods for a base station to perform a method construct dynamic hierarchical sub-configurations of bandwidth parts (BWPs) for use in a connected mode discontinuous reception (CDRX) communication session with a user equipment (UE) device. The base station may configure a first BWP at a baseband frequency associated with the CDRX communication session as a default BWP, a second BWP with a wider bandwidth than the first BWP as a transmission BWP, and one or more third BWPs as resting BWPs. The transmission BWP and the one or more resting BWPs may be configured to periodically override the default BWP as the active BWP for a predetermined number of CDRX cycles. The transmission BWP may be utilized, when activated to perform data transmission by UE device, and the one or more resting BWPs may be utilized, when activated, for performing channel measurements.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using frequency division multiplexing. The wireless device may establish a first wireless link with a first base station according to a first radio access technology (RAT) and a second wireless link with a second base station according to a second RAT. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether the wireless device has uplink activity scheduled according to both the first RAT and the second RAT. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth using frequency division multiplexing.

Abstract: A display may include an array of pixels covered by lenticular lenses. The lenticular lenses may cause expansion of light primarily in a horizontal direction. To improve the perceived resolution of the display, the horizontal resolution of the pixels on the display may be increased. In one possible layout, each pixel includes one red sub-pixel, one blue sub-pixel, and one green sub-pixel. The sub-pixels may be non-square rectangular. The sub-pixels may be the same size or may have the same widths and different heights. Each pixel may be asymmetric about a horizontal axis. In a given row, the pixels may alternate between first and second layouts. The second layout may be a vertically flipped version of the first layout.

Abstract: This disclosure relates to performing cellular communication using a power efficient downlink control information framework. A wireless device and a cellular base station may exchange configuration information indicating that the cellular base station and the wireless device support a sleep downlink control information (sDCI) format. An sDCI configuration according to the sDCI format may be negotiated, including selecting at least one sDCI configuration parameter based at least in part on an application type currently associated with cellular communication between the cellular base station and the wireless device. Downlink control information may be provided during one or more subframes in accordance with the sDCI configuration. One or more subframes for which no downlink control information will be provided to the wireless device may be determined based at least in part on the sDCI configuration.
