  • Publication number: 20250261284
    Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

  • Publication number: 20250254636
    Abstract: Techniques discussed herein can facilitate neighbor cell measurements with non-cell-defined synchronization signal blocks (NCD-SSB). One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive an indication of a NCD-SSB and a cell-defined (CD)-SSB (CD-SSB) configuration. The one or more processors further perform a measurement procedure to obtain a cell measurement value associated with a SSB wherein the SSB is one of the NCD-SSB or the CD-SSB. Subsequently, the one or more processors compare the cell measurement value with a threshold value; and perform measurement of a neighbor cell when the cell measurement value does not satisfy the threshold value.
