  • Discontinuous receive for contention-based radio access technologies
    Patent number: 10165605
    Abstract: Aspects described herein relate to receiving communications in contention-based radio access technologies (RAT). Communication resources can be activated for monitoring one or more channels related to a contention-based RAT based at least in part on a discontinuous receive (DRX) cycle. The one or more channels related to the contention-based RAT can be monitored in one or more time periods following activating the communication resources to determine whether communications are received from an access network node. An on-duration timer during which the communication resources remain active to receive the communications in the contention-based RAT can be initialized based at least in part on determining that the communications are received from the access network node. The communication resources can be deactivated following expiration of the on-duration timer.

  • Scheduling request transmission for directional beam access
    Patent number: 10154514
    Abstract: A user equipment (UE) may transmit a UE-generated uplink message to a base station to request resources for an uplink transmission. The UE may be configured to send the message (e.g., a scheduling request (SR)) using different transmission modes. For example, the UE may transmit the SR using a scheduled mode where the UE conveys the SR along with another uplink message (e.g., a control message). In some examples, the UE may transmit the SR using an autonomous mode where the UE transmits the SR in resources reserved for SR transmissions. The UE may determine which transmission mode to use based on certain characteristics of the SR or the data associated with the SR.

    Abstract: Real-time job distribution software architectures for high bandwidth, hybrid processor computation systems for semiconductor inspection and metrology are disclosed. The imaging processing computer architecture can be scalable by changing the number of CPUs and GPUs to meet computing needs. The architecture is defined using a master node and one or more worker nodes to run image processing jobs in parallel for maximum throughput. The master node can receive input image data from a semiconductor wafer or reticle. Jobs based on the input image data are distributed to one of the worker nodes. Each worker node can include at least one CPU and at least one GPU. The image processing job can contain multiple tasks, and each of the tasks can be assigned to one of the CPU or GPU in the worker node using a worker job manager to process the image.

    Abstract: Methods and systems for detecting defects in patterns formed on a specimen are provided. One system includes one or more components executed by one or more computer subsystems, and the component(s) include first and second learning based models. The first learning based model generates simulated contours for the patterns based on a design for the specimen, and the simulated contours are expected contours of a defect free version of the patterns in images of the specimen generated by an imaging subsystem. The second learning based model is configured for generating actual contours for the patterns in at least one acquired image of the patterns formed on the specimen. The computer subsystem(s) are configured for comparing the actual contours to the simulated contours and detecting defects in the patterns formed on the specimen based on results of the comparing.

  • BEAM SWITCHING AND RECOVERY
    Publication number: 20180294937
    Abstract: Apparatuses and methods of beam switching are presented. A beam switch message (BSM) is transmitted to a second device via a first beam set. The BSM includes a command to switch from communication via the first beam set to communication via a second beam set at a switch time. It is determined whether a response message is received from the second device via the first beam set, the response message indicating that the second device received the BSM. A communication is sent to the second device via the second beam set after the switch time when the response message is unreceived.

  • TECHNIQUES AND APPARATUSES FOR BEAM MANAGEMENT
    Publication number: 20180270689
    Abstract: A user equipment (UE) may operate in a reception mode that includes a set of sleep cycles and a set of wake cycles. During a sleep cycle of the UE, a signal quality of an active beam carrying a control channel or a data channel may degrade. This may result in the UE failing to decode the control channel or the data channel during a subsequent wake cycle. In some aspects, the UE may perform a measurement of one or more beams, of a set of beams, prior to the wake cycle. In some aspects, the UE may identify a beam, of the one or more beams, to use for communication with a base station (BS). In this way, the UE reduces a delay in data transfer associated with performing beam recovery after failing to decode the control channel or data channel during the wake cycle.

  • Systems and methods for updating links between keywords associated with a trending topic
    Patent number: 10068023
    Abstract: Systems and methods are described herein for updating links between keywords associated with a trending topic. Control circuitry may identify a plurality of communications associated with a plurality of users, the plurality of communications being related to a topic. The communications may comprise, for example, emails, text messages, online social media posts, websites or portions of a website, or any other online communication. The control circuitry may determine whether the topic is trending and increase a strength of association between a first symbol associated with the topic and a second symbol associated with the topic such that when a search query is received that includes the first symbol, search results related to the second symbol have a higher probability of being returned.

  • Determining multi-patterning step overlay error
    Patent number: 10062543
    Abstract: Methods and systems for determining overlay error between different patterned features of a design printed on a wafer in a multi-patterning step process are provided. For multi-patterning step designs, the design for a first patterning step is used as a reference and designs for each of the remaining patterning steps are synthetically shifted until the synthetically shifted designs have the best global alignment with the entire image based on global image-to-design alignment. The final synthetic shift of each design for each patterning step relative to the design for the first patterning step provides a measurement of relative overlay error between any two features printed on the wafer using multi-patterning technology.
