  • Publication number: 20260247188
    Abstract: Techniques, described herein, include solutions for interruption arrangement for a User Equipment (UE) performing gap-less measurements. Traditionally, a UE configured a time duration, known as a measurement gap, to prepare Radio Frequency (RF) circuitry for performing measurement and to perform measurement. By using spare RF circuitry to perform measurement, a UE may perform ‘gap-less’ measurement without a measurement gap. When preparing for gapless measurement, interruption may occur depending on many factors that may vary depending on the UE and the currently active frequency bands. The UE may use interrupts for the time required to prepare the spare RF circuitry to perform gapless measurement. The UE may communicate to the network a temporal location, and a duration, of the interrupts via various information elements (IEs), so that the network may know when interrupts are allocated.

  • Patent number: 12711172
    Abstract: A topic mapping system generates customized mapping schemas for multiple topic sets. The topic mapping system generates document clusters that represent groups of digital documents. The topic mapping system also generates, for each topic set, a document-topic mapping data object (“DTM data object”) that describes a customized mapping schema of the document clusters to labels in the topic set. The topic mapping system identifies customized groups of documents for responding to multiple requests that have a particular keyword. For each request, the topic mapping system identifies a particular topic set and DTM data object associated with a computing system that provided the request. Based on the keyword, the topic mapping system identifies documents that are categorized according to the customized mapping schema in the DTM data object. The topic mapping system can provide customized groups of documents to respective computing systems that provided the multiple requests.

  • Publication number: 20260238310
    Abstract: A user equipment (UE) includes a first and second receiving (RX) panel and is configured to determine the UE is to perform Layer-1 (L1) measurements on beams transmitted by a first and second transmission and reception point (TRP), wherein the UE tests a minimum number of beams using beam sweeping operations prior to selecting the beams for L1 measurements, wherein the minimum number corresponds to a number of beam sweeping rounds. In a first beam sweeping round, the UE simultaneously activates the first and second RX panels to generate one RX beam for a beam sweeping operation. In subsequent beam sweeping rounds, the UE performs beam sweeping operations until the minimum number of beams are tested, selects a first beam of the first TRP and a second beam of the second TRP for the L1 measurements and performs the L1 measurements.

  • Publication number: 20260239241
    Abstract: Systems and methods for performing inter-frequency and intra-frequency measurements without measurement gap use are discussed herein. A UE receives, from a network, configuration information for performing an inter-frequency or intra-frequency synchronization signal block (SSB) measurement outside of an active bandwidth part (BWP) without a measurement gap, and, in response, performs, without using the measurement gap, the inter-frequency/intra-frequency SSB measurement on an inter-frequency/intra-frequency SSB that is located outside of the active BWP and within a UE channel bandwidth (CBW) corresponding to the active BWP. Capability information detailing whether the UE supports this behavior may be provided from the UE to the network. The network may provide a threshold for a measurement object (MO) that is used by the UE to determine whether to perform such SSB measurements without a measurement gap.
