  • Patent number: 12108291
    Abstract: Embodiments of the present disclosure enable a user equipment (UE) to performing inter-Radio Access Technology (RAT) measurements. The UE determines whether one or more inter-RAT measurement object (MO) is configured with or without a measurement gap (MG). When the one or more inter-RAT MO is on an NR serving component carrier (CC) with the MG, the UE performs an inter-RAT measurement on the NR serving CC based on whether the MG is fully overlapped or partially overlapped with synchronization signal blocks (SSBs) of a target MO of the one or more inter-RAT MO. When the one or more inter-RAT MO is on the NR serving CC without the MG, the UE performs the inter-RAT measurement on the NR serving CC based on whether a target SSB of the target MO is within or outside an active bandwidth part (BWP) of the NR serving CC.

  • Publication number: 20240314581
    Abstract: Methods and systems to activate beams for beam switching based on measurements of a downlink reference signal that is QCL Type-D with a downlink pathloss reference signal are disclosed. A UE may measure and report to a base station the RSRP of the reference signal that is QCL Type-D with a target downlink pathloss reference signal. Based on the reported RSRP measurements, the base station may activate the target pathloss reference signal to command the UE to update the pathloss measurements of the target pathloss reference signal for uplink power control of a beam corresponding to the target pathloss reference signal. The UE may determine whether the target pathloss reference signal is considered known for uplink power control based on the timing relationship among the reception of the reference signal from the base station, the transmission of the RSRP measurement of the reference signal, and reception of the activation command.

  • Publication number: 20240297705
    Abstract: Methods, apparatuses, and systems are disclosed for compensating for cell identification delays that are beyond the control of the UE, in connection with standards-specified cell identification timing limits. In frequency bands including both beam sweeping and listen-before-talk (LBT) requirements, a cell identification procedure may be significantly delayed due to LBT failure at the base station and/or beam misalignment between the base station and the UE. Therefore, UE cell identification timing constraints may be dynamically adjusted to compensate for such delays. For example, the time window allowed for cell identification of a neighbor cell may be dynamically increased in response to determining that one or more SSBs were not available at the UE during an SMTC occasion. In some scenarios, if the timing increase exceeds a predetermined threshold, the UE may restart the cell identification procedure, e.g., on the same frequency layer or on a different frequency layer.
