  • Patent number: 12732792
    Abstract: A method for of wireless communication, by a multi-subscription user equipment (UE) includes selecting a first subscription to receive a positioning system information broadcast (posSIB) based on a first subscription state and a second subscription state. The method also includes receiving the posSIB via the first subscription.

  • Publication number: 20260261922
    Abstract: In some implementations, a user equipment (UE) may detect a trigger to provide a measurement report associated with a redirection from a first radio access technology (RAT) to a second RAT. The trigger may be a reference signal metric associated with the second RAT satisfying a threshold associated with the reference signal metric. The threshold may be configured by a base station. The UE may selectively provide the measurement report based at least in part on whether one or more other reference signal metrics satisfy one or more other thresholds corresponding to the one or more other reference signal metrics.

  • Publication number: 20260247264
    Abstract: A user equipment (UE) receives a SIB1 message from a base station. The SIB1 message lists first and second public land mobile network identifiers (PLMN IDs), the first PLMN ID having a corresponding tracking area code (TAC) and the second PLMN ID not having a TAC. The UE reports the first PLMN ID and TAC but not the second PLMN ID while performing PLMN selection. In another aspect, the UE unsuccessfully attempts to select or reselect to a shared cell of the base station with the second PLMN ID. In response to the failed attempt, the UE bars the shared cell as a candidate for cell selection/reselection, due to a missing TAC. When the UE attempts to select or reselect to the shared cell with the first PLMN ID, which may or may not have a TAC, the UE reevaluates the barring due to selection of the first PLMN ID.

  • Publication number: 20260230887
    Abstract: This disclosure provides methods, components, devices and systems for MDT measurement and reporting in mixed network deployments. Some aspects specifically relate to optimizing logged MDT measurements in network deployments including NTN cells and TN cells. In some examples, a UE receives, from a network entity, a logged measurement configuration which indicates whether the UE is configured to limit its MDT measurements to NTN cells or TN cells during an MDT session, or whether the UE is not limited and may report measurements for both NTN and TN cells. In some examples, the logged measurement configuration may further indicate, when the UE is not limited in its MDT measurements, whether the NTN cells or the TN cells are prioritized for MDT measurement and reporting. The prioritization may be based on a UE state or capability. In further examples, these aspects may be extended to other network deployments including SONs and SBAs.

  • Publication number: 20260231006
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may search for a network using a set of predicted mobile country codes (MCCs) during a flight. Some aspects more specifically relate to detecting an MCC in accordance with a set of predicted MCCs, where the set of predicted MCCs are used for the detection based at least in part on the detection occurring during the pre-landing time window. In some aspects, the detection of the MCC occurs during a pre-landing time window. For example, the UE may be in a low-power mode during the pre-landing time window and during detection of the MCC. In some aspects, the UE may determine the set of predicted MCCs, for example, according to a length of the flight and a source (such as a source airport or a source MCC).
