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: A display includes a plurality of pixels grouped into a plurality of lines of pixels. Each line of pixels of the plurality of lines comprises a group of pixels of the plurality of pixels that are coupled to a common scan line as well and that are coupled to different data lines to individually activate each pixel of the group of pixels. The display also includes a common voltage (VCOM) driving circuit configured to receive a waveform and drive the waveform to the display as a VCOM having a value tailored to an individually activated pixel of the group of pixels.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for a UE to request a beam quality measurement procedure. A user equipment device may be configured to perform a method including performing transmitting a request to perform a beam quality measurement procedure for downlink receptions (e.g., a P3 procedure) to a base station/network entity, receiving instructions to perform the beam quality measurement procedure from the base station, and transmitting results of the beam quality measurement procedure to the base station. In some embodiments, transmission of the request may be response to at least one trigger condition and/or detection of a condition at the UE. The request may include an indication of a preferred timing offset. The instructions to perform the beam quality measurement procedure may include a schedule for the beam quality measurement.

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: A device, system and method for determining when to initiate certain operations associated with received data. The method is performed at a device connected to a network. The method includes estimating a first number of repetitions of a subframe which is associated with a likelihood that the device will successfully perform an operation based on the subframe. The method further includes delaying initiating the operation for the subframe until a received number of repetitions of the subframe is greater than or equal to the first number of repetitions.

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: Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.
