Abstract: Techniques are disclosed relating to handling preemptive data services in cellular wireless transmissions. In some embodiments, a device wirelessly transmits uplink data for a first data service during a time dimension duplex (TDD) scheduled transmission interval using a first frequency band. While transmitting, in these embodiments, the device also monitors a downlink control channel that uses a second frequency band that does not overlap with the first frequency band. The downlink control channel may be dedicated for preemption indicators that indicate another service is preempting scheduled resources. In response to detecting an indicator in the downlink control channel of communications for a second data service in the first frequency band during the scheduled transmission interval, the device may reduce the transmission of the uplink data on resources used for the communications for the second data service (e.g., by blanking or transmitting at a lower power).

Abstract: A network device (e.g., a user equipment (UE), or a new radio NB (gNB)) can process or generate a configuration of physical downlink control channel (PDCCH) monitoring in different search spaces sets independently from one another in order to manage different services optimally. A processor of the network device can be configured to receive physical downlink control channel (PDCCH) candidates of a PDCCH in a slot for channel estimation across search spaces of the slot. Different priorities can be determined among the PDCCH candidates in the slot based on a priority rule. Then a number of PDCCH candidates can be skipped/dropped from monitoring based on the different priorities of the PDCCH candidates to ensure that a threshold level of blind decoding operations across a plurality of slots of the PDCCH is being satisfied. The UE can monitor a portion of the PDCCH candidates while concurrently skipping another.

Abstract: The method includes receiving, from a user, a first speech input spoken in a first language; inferring a user intent based on at least the first speech input in the first language; based on the inferred user intent, generating one or more alternative expressions of the first speech input in the first language; and providing feedback to the user introducing the alternative expressions as a more preferred input to express the inferred user intent than the first speech input provided by the user.

Abstract: The systems, methods, and apparatuses can receive one or more communication signals traversing through a communication channel. The systems, methods, and apparatuses can estimate one or more known parameters, characteristics, and/or attributes of the communication channel, for example, scattering, fading, and/or power decay over distance, through a process referred to as channel estimation. The systems, methods, and apparatuses can develop various channel coefficients, for example, amplitudes and/or phases, describing the channel response of the communication channel at discrete intervals of time, also referred to as taps. The systems, methods, and apparatuses can assign taps to various priorities and, thereafter, utilize these priorities to selectively include their corresponding channel coefficients in a CSI report or exclude their corresponding channel coefficients from the CSI report.

In one embodiment, for example, an apparatus may include at least one memory and logic for an evolved node B (eNB), at least a portion of the logic comprised in hardware coupled to the at least one memory. The logic may be operative to forward downlink (DL) data received from a serving gateway (SGW) to user equipment (UE), transmit a handover command to the UE to trigger execution of a handover (HO) process to handover the UE to a target eNB, continue forwarding at least a portion of the DL data to the UE following transmission of the handover command, and terminate transmission of the DL data to the UE responsive to detecting a stop DL data event. Other embodiments are described and claimed.

Abstract: Embodiments described herein relate to managing bearers in a radio access network (e.g., next generation RAN (NG-RAN), etc.). In one example, a central-unit control-plane (CU-CP) communicates with a distributed unit (DU) and a CU-UP to exchange transport network layer addresses (TNLAs) and tunnel endpoint identifiers (TEIDs) between the DU and the CU-UP. In this way, the DU becomes resistant to the CU-UP's rejection of a bearer setup request from the CU-CP during a bearer setup procedure. Furthermore, during virtual machine (VM) migration or local problems of the CU-UP, an E1 procedure known as “bearer relocate” can be defined to notify the DU of a new TNLA for one or more affected general packet radio service tunneling protocol (GTP) tunnels that are affected by the VM migration or local problems.

A method includes receiving an indication to provide a preview mode on a display of the computing device, providing screenshots of a plurality of applications in the preview mode such that the screenshots are accessible for viewing by a user. The method also includes identifying the first application to provide the first screenshot in an updated mode and changing a state of the first application from a suspended state to an inactive state by allocating processing time of the one or more processors to the first application, and displaying updates of the first screenshot while the first application is in the inactive state.

Abstract: The disclosed embodiments provide a system that manages use of a battery in a portable electronic device. During operation, the system operates a charging circuit for converting an input voltage from a power source into a set of output voltages for charging the battery and powering a low-voltage subsystem and a high-voltage subsystem in the portable electronic device. Upon detecting the input voltage from the power source and a low-voltage state in the battery during operation of the charging circuit, the system uses a first inductor group in the charging circuit to down-convert the input voltage to a target voltage of the battery that is lower than a voltage requirement of the high-voltage subsystem. The system also uses a second inductor group in the charging circuit to up-convert the target voltage to power the high-voltage subsystem.

Abstract: Various implementations disclosed herein include devices, systems, and methods that create additional depth frames in the circumstance wherein a depth camera runs at a lower frame rate than a light intensity camera. Rather than upconverting the depth frames by simply repeating a previous depth camera frame, additional depth frames are created by adjusting some of the depth values of a prior frame based on the RGB camera data (e.g., by “dragging” depths from their positions in the prior depth frame to new positions for a new frame). Specifically, a contour image (e.g., identifying interior and exterior outlines of a hand with respect to a virtual cube that the hand occludes) is generated based on a mask (e.g., occlusions masks identifying where the hand occludes the virtual cube). Changes in the contour image are used to determine how to adjust (e.g., drag) the depth values for the additional depth frames.

Abstract: Techniques for generating interest embedding vectors are disclosed. In some embodiments, a system/process/computer program product for generating interest embedding vectors includes aggregating a plurality of web documents associated with one or more entities, wherein the web documents are retrieved from a plurality of online content sources including one or more websites; selecting a plurality of tokens based on processing of the plurality of web documents; and generating embeddings of the selected tokens in an embedding space.

Abstract: Techniques are disclosed relating to biometric authentication, e.g., facial recognition. In some embodiments, a device is configured to verify that image data from a camera unit exhibits a pseudo-random sequence of image capture modes and/or a probing pattern of illumination points (e.g., from lasers in a depth capture mode) before authenticating a user based on recognizing a face in the image data. In some embodiments, a secure circuit may control verification of the sequence and/or the probing pattern. In some embodiments, the secure circuit may verify frame numbers, signatures, and/or nonce values for captured image information. In some embodiments, a device may implement one or more lockout procedures in response to biometric authentication failures. The disclosed techniques may reduce or eliminate the effectiveness of spoofing and/or replay attacks, in some embodiments.

Abstract: A technique for dynamically adjusting power use of an input/output (I/O) interface of an electronic device is provided. The electronic device includes an input/output (I/O) interface that facilitates electronic communications with a receiving electronic device, at a particular transmission rate that is dynamically changeable by the electronic device. Transmission power and transmission rate adjustment circuitry determines whether a step-down in a transmission power used for signal transmission at the particular transmission rate is desirable. When desirable, the transmission power is dynamically adjusted down one step, such that less power is used by the I/O interface during the electronic communications.

Abstract: Video compression and decompression techniques are disclosed that provide improved bandwidth control for video compression and decompression systems. In particular, video coding and decoding techniques quantize input video in multiple dimensions. According to these techniques, pixel residuals may be generated from a comparison of an array of input data to an array of prediction data. The pixel residuals may be quantized in a first dimension. After the quantization, the quantized pixel residuals may be transformed to an array of transform coefficients. The transform coefficients may be quantized in a second dimension and entropy coded. Decoding techniques invert these processes. In still other embodiments, multiple quantizers may be provided upstream of the transform stage, either in parallel or in cascade, which provide greater flexibility to video coders to quantize data in different dimensions in an effort to balance the competing interest in compression efficiency and quality of reconstructed video.
