  • Patent number: 12099613
    Abstract: A method, computer program product, and computer system for repairing a Dockerfile. Library versions containing initial version numbers of libraries are extracted from the Dockerfile. A Monte Carlo tree search (MCTS) is executed, using the extracted library versions as input, which generates a tree that includes multiple levels populated with noses. Each node in a level represents the generic library name of a library version in the Dockrerfile and an associated randomly selected version number. At least one of the randomly selected version numbers associated with at least one node in a level differs from the initial version number associated with a versionf. A best successful installation path is selected from the at least one successful installation path. The Dockerfile is repaired by inserting randomly selected version numbers into Dockerfile as replacements for some of the initial version numbers.

  • Publication number: 20240313846
    Abstract: The aspects described herein may improve beam management at an apparatus (e.g., a UE) by allowing the apparatus to proactively transmit a beam report including information that may avoid a full beam failure recovery (BFR) procedure at the apparatus. The apparatus receives a set of beam failure detection reference signals and transmits a beam report indicating a partial beam failure when a radio link quality of at least a first beam failure detection reference signal in the set of beam failure detection reference signals is less than a quality threshold and a radio link quality of at least a second beam failure detection reference signal in the set of beam failure detection reference signals is greater than or equal to the quality threshold.

The apparatus receives, from a base station, DCI indicating a unified TCI state of a plurality of unified TCI states for one or more channels and a dummy indication related to a TCI indication field and a PDSCH schedule. The apparatus determines an action in response to the dummy indication. The apparatus communicates with the base station based on the action determined in response to the dummy indication. The apparatus, to determine the action in response to the dummy indication, may maintain the unified TCI state for the one or more channels based on the TCI indication field of the dummy indication.

  • Publication number: 20240314807
    Abstract: Certain aspects of the present disclosure provide techniques for configuring user equipment (UE) beam switching in multiple transmission/reception points (multi-TRPs) communications. In particular, the present disclosure provides techniques for harmonizing downlink panel switching and uplink panel switching using transmission configuration indicator (TCI) codepoints, such that in some cases, a single downlink control information (DCI) may convey multiple TCI states for multiple panels or multi-TRPs. For example, a UE receives a first DCI indicating a first TCI codepoint from TCI codepoints activated by a media access control (MAC) control element (CE). The UE receives a second DCI scheduling an uplink transmission from the UE or a downlink transmission to the UE and conveying panel switching information. The UE processes the scheduled uplink transmission and/or downlink transmission based on one or more (joint) TCI states mapped to the first TCI codepoint and the panel switching information (e.g.

The embodiment may encode each of the obtained OCR text lines into semantic vectors and each of the associated bounding boxes into position vectors to generate a knowledge graph using fusion vectors derived therefrom. The embodiment may receive a query including a key value. The embodiment may identify a series of candidate nodes including a series of most similar nearby nodes positioned near a first node associated with the key value. The embodiment may generate prompt template to determine closeness of the candidate nodes to the key value and calculate associated confidence levels. The embodiment may output extraction information associated with the candidate node having a highest calculated confidence level.

  • Publication number: 20240302989
    Abstract: Described are techniques for application-consistent snapshots. The techniques include determining that a scheduled snapshot of a storage volume is imminent, where the storage volume stores input/output (I/O) data associated with an application that executes on a host server. The techniques further include initiating at least one host buffer flush prior to the scheduled snapshot being performed, where I/O data in a host buffer associated with the application is transferred to a write cache of the storage volume to reduce an amount of I/O data in the host buffer when performance of the scheduled snapshot begins. The techniques further include initiating, after the host buffer flush has completed, a write cache flush to write the I/O data in the write cache to the storage volume. The techniques further include initiating the scheduled snapshot of the storage volume in response to an indication that the write cache flush has completed.

  • Publication number: 20240276584
    Abstract: This disclosure provides systems, methods and apparatus for applying a unified transmission configuration indicator (TCI) state to a downlink reference signal in accordance with a rule or procedure that is mutually known between a user equipment (UE) and one or more components of a base station (BS). In one aspect, the UE and one or more components of the BS may support a unified TCI state associated with a transmission over a downlink data channel and a transmission over a downlink control channel. The UE and one or more components of the BS may apply the unified TCI state to the downlink reference signal (which may be associated with beam selection for the downlink reference signal) in accordance with a satisfaction of a condition associated with the downlink reference signal. Such a condition may be associated with one or more parameters or configurations associated with the downlink reference signal.

  • Publication number: 20240276389
    Abstract: Aspects relate to identifying power control parameters for a transmission on a bandwidth part (BWP) and component carrier (CC). In some examples, a user equipment (UE) identifies power control (PC) parameters to be used for a first BWP and CC when a common set of transmission configuration indicator (TCI) states is configured for a reference BWP and CC, and where the common set of TCI states is shared at least between the reference BWP and CC and the first BWP and CC. For example, the UE may transmit a transmission using PC parameters that are identified based on a first TCI state identifier (ID) for the common set of TCI states. In some examples, a UE identifies PC parameters to be used for a BWP and CC based on whether a path loss reference signal is configured for a TCI state on a reference BWP and CC.
