  • Patent number: 10846442
    Abstract: Methods provide computationally efficient techniques for designing gauge patterns for calibrating a model for use in a simulation process. More specifically, the present invention relates to methods of designing gauge patterns that achieve complete coverage of parameter variations with minimum number of gauges and corresponding measurements in the calibration of a lithographic process utilized to image a target design having a plurality of features. According to some aspects, a method according to the invention includes transforming the space of model parametric space (based on CD sensitivity or Delta TCCs), then iteratively identifying the direction that is most orthogonal to existing gauges' CD sensitivities in this new space, and determining most sensitive line width/pitch combination with optimal assist feature placement which leads to most sensitive CD changes along that direction in model parametric space.

  • Publication number: 20200367221
    Abstract: Resource usage information is determined at a first UE about usage of a first communication resource by other UEs based on signals received by the UE. The first communication resource is excluded from a set of candidate communication resources when the resource usage information exceeds a usage threshold. When the first communication resource is excluded, a second communication resource from the candidate communication resources remaining in the set is selected to use for a transmission by the UE.

  • Patent number: 10839131
    Abstract: A three-dimensional mask model that provides a more realistic approximation of the three-dimensional effects of a photolithography mask with sub-wavelength features than a thin-mask model. In one embodiment, the three-dimensional mask model includes a set of filtering kernels in the spatial domain that are configured to be convolved with thin-mask transmission functions to produce a near-field image. In another embodiment, the three-dimensional mask model includes a set of correction factors in the frequency domain that are configured to be multiplied by the Fourier transform of thin-mask transmission functions to produce a near-field image.

  • Patent number: 10833811
    Abstract: Methods and devices utilizing sidelink transmission between user equipment (UEs) for HARQ retransmission are provided. The sidelink HARQ retransmissions include data from the initial transmission or an outer coded version thereof. HARQ feedback from the targeted receiver of the initial transmission may identify code block groups and/or individual code blocks the target receiver did not successfully decode. A UE that has not successfully decoded an entire transport block, may still cooperate in HARQ retransmission for the targeted receiver of the transport block by retransmitting at least a subset of the code block groups that it was able to successfully decode for the transport block.

  • Patent number: 10833822
    Abstract: In a wireless communication system, user equipments (UEs) may be partitioned into different groups, e.g. based on spatial separation. UEs may use multiple access (MA) signatures that have low or no correlation to each other if the UEs are in the same group. The MA signatures used by one group of UEs may be more correlated with the MA signatures used by another group of UEs. If the UEs are partitioned into the different groups based on spatial separation, then the spatial separation between the different groups may assist in increasing the reliability of detection if two UEs in different groups use correlated MA signatures.

  • Patent number: 10824897
    Abstract: An online system receives an image associated with a set of pixel values and provides the set of pixel values to a deep learning or machine-learned model that is trained to assign a set of regions of interest within the image to one or more classes. The model is structured to identify the set of regions of interest based on the pixel values, in which each region of interest is associated with an embedding corresponding to a vector representation of the region of interest. The online system compares each embedding to a database of embeddings associated with multiple labeled images, in which the labels indicate an identity of a brand and/or an obfuscated identity of the brand. The online system then determines whether the identity of the brand and/or the obfuscated identity of the brand is/are detected within each region of interest based on the comparison.

  • Patent number: 10803322
    Abstract: Multiple sensors are automatically recruited and coordinated to chronicle a fleeting event in a collaborative manner across time and space. An event of interest is captured and recognized by a first data capturing device. An outcome is automatically predicted, and a second data capturing device likely to have visibility of the location during occurrence of the predicted outcome is recruited to provide surveillance data of the event of interest. Surveillance data from both the first and second and subsequent data capturing devices are automatically sent to an investigation facility.

  • Publication number: 20200322939
    Abstract: Systems and methods for sidelink configuration are provided. A transmitting user equipment (UE) transmits configuration parameters relating to a sidelink transmission between the UE and a second UE via higher-layer signalling and then transmits the sidelink transmission to the second UE. The higher layer signalling is a layer above the sidelink transmission. The parameters may include feedback channel parameters or parameters for sidelink reference signal transmission by the second UE. The parameters may be selected by the transmitting UE, or they may be received initially from the network. The parameters may be part of a sidelink configured grant configuration (SL CG) signalled to the second UE. The sidelink transmission may be a configured-grant transmission to the second UE according to the SL CG configuration. The higher layer signalling may be PC5 signalling or RRC signaling.

  • Publication number: 20200322100
    Abstract: Systems and methods for early termination of feedback in respect of sidelink transmissions are provided. A first UE transmits at least one sidelink (SL) transmission of a first set of SL transmissions to a second UE, the first set of SL transmissions comprising an initial SL transmission and a set number of SL retransmissions. If no ACK is received, then the first UE transmits the set number of retransmissions. On the other hand, if an ACK is received, then the first UE transmits fewer than the set number of SL retransmissions when an ACK is received from the second UE before the set number of SL retransmissions has been completed. By transmitting fewer than all of the set number of SL retransmissions, resources can be freed up for other purposes. The approach may be used for SL configured grant transmission.
