  • Publication number: 20240114373
    Abstract: Aspects relate to activation of a cell (e.g., an SCell) based on measurements made by a user equipment (UE) when the cell is not activated with respect to (e.g., as a secondary cell for) the UE (e.g., the cell is deemed by the network as an unknown cell for that UE). In this case, when the network requests the UE to conduct measurements with respect to that cell (e.g., in conjunction with activation of the cell), the UE may report information based on the measurements the UE conducted when the cell was not activated with respect to that UE.
