  • Publication number: 20260270132
    Abstract: A user equipment (UE) includes a transceiver and a processor. The processor is configured to receive, in a time division duplex (TDD) band, a configuration for a serving cell signal that includes a plurality of symbols. The plurality of symbols corresponds to symbols of at least one synchronization signal block (SSB) for SSB-based radio resource management (RRM) measurement for a serving cell or a neighbor cell, and at least one symbol for uplink (UL) transmission. The processor is configured to, in response to determining that the relative position of the at least one symbol for the UL transmission is after a last symbol for the SSB-based RRM measurement in an SSB-based RRM measurement timing configuration (SMTC) window, restrict the UL transmission for a number of symbols that are after the last symbol of the symbols for the SSB-based RRM measurement in the SMTC window.

A user equipment (UE) may receive a synchronization signal (SS)/physical broadcast channel (PBCH) block (SSB) at a raster point of a frequency raster used for identifying channels having channel bandwidths of less than 5 MHz, may identify that a channel corresponding to the SSB has a bandwidth that is less than 5 MHz based on a formulation of a PBCH of the SSB, and may use, based on the SSB, the channel to synchronize to a cell. Radio access network (RAN) behaviors related to the formulation of such PBCHs of such SSBs are also disclosed. Some embodiments for formulating such PBCHs contemplate particular arrangements for PBCH demodulation reference signals (DMRSs).

  • Publication number: 20260270898
    Abstract: Systems and methods for radio resource management (RRM) measurement periodicity enhancements are disclosed herein. In some cases, a user equipment (UE) receives, from a network: a synchronization signal block (SSB)-based measurement timing configuration (SMTC) that indicates an SMTC periodicity for a target serving cell. The UE also receives an SSB periodicity of SSBs on the target serving cell. Then, the UE uses the SMTC periodicity and the SSB periodicity to determine a detection and measurement periodicity for the target serving cell, and proceeds to perform detection of the target serving cell and measurement of the target serving cell according to the detection and measurement periodicity. In some such cases, the UE uses the SSB periodicity value as the detection and measurement periodicity for the target serving cell. Cases where only one (or neither) of the SMTC periodicity and/or the SSB periodicity are provided to the UE are also explained.

  • Publication number: 20260269922
    Abstract: Systems and methods for reducing measurement delay for group-based beam reporting (GBBR) are disclosed herein. A user equipment (UE) having first and a second antenna panels receives, from a network, a pair of channel measurement resource (CMR) sets identifying reference signals transmitted across a pair of transmission reception points (TRPs) and that are together transmitted periodically. The UE measures the reference signals using narrow beams within a plurality of broader beams that each correspond to one of the reference signals and that is on one of the antenna panels and selects first and second narrow beams (one on each antenna panel) to use for simultaneous downlink (DL) reception. The UE sends a beam report indicating one reference signal from each CMR set that is associated with one of the two selected narrow beams. Herein, particular methods for efficiently making the measurements across the two antenna panels are disclosed.

  • Publication number: 20260267618
    Abstract: The present disclosure is directed toward systems, methods, and non-transitory computer readable media that finetune large language models for code generation based on code execution results using preference-guided learning. For example, the disclosed systems utilize a large language model to generate a set of code responses from a natural language query, wherein the set of code responses correspond to code. Furthermore, the disclosed systems compare the set of code responses to a ground truth code response to generate a set of correct code responses and a set of incorrect code responses. The disclosed systems generate a preference dataset from preference pairs selected from the set of correct code responses and the set of incorrect code responses. In addition, the disclosed systems finetune the large language model by modifying parameters of the large language model to reduce incorrect code responses according to a loss function based on the preference dataset.

  • Publication number: 20260270913
    Abstract: Systems and methods for regulating uplink (UL) transmission timing differences (TTDs) at a user equipment (UE) are discussed herein. A UE may determine that a first uplink (UL) TTD between a first UL transmission timing for a first timing advance group (TAG) and a second UL transmission timing for a second TAG is above a threshold, may start a first TTD reconfiguration timer at the UE in response, and may send, to a network, a message indicating that the UE has started the first TTD reconfiguration timer. The network may then provide a configuration to the UE that lowers or renders inapplicable the UL TTD that is of concern. If no new network configuration is provided to the UE prior to expiration of the TTD reconfiguration timer, the UE may drop UL transmission use toward one of the TAGs. Considerations for thresholds for triggering such TTD reconfiguration timers are discussed.

  • Patent number: 12726538
    Abstract: Optimization of data synchronization latency when load balancing requests is provided. A request directed to a first server device in the first region is offloaded to a second server device in a second region that is different from the first region for load balancing. Data is generated based on processing the request by the second server device in the second region. A target region of a client device requesting the generated data is dynamically determined such that the target region is different from the second region. The generated data is stored in a datastore of the target region of the client device requesting the generated data. Thus, data is advantageously directly stored in the region(s) where clients are requesting that data without needing to wait for eventual synchronization of data to the region(s) where clients are requesting that data.

  • 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.
