a processor; and

a memory storing instructions, wherein the instructions, when run by the processor, cause the UE to, upon initiation of an radio resource control (RRC) connection reestablishment procedure and based on a determination by the UE that the UE is not configured with a conditional handover configuration, release Master Cell Group (MCG) Secondary Cell(s) (SCell(s)), release a special cell configuration configured in an spCellConfig information element (IE), release a configuration in an delayBudgetReportingConfig information element (IE) and stop timer T342, and release a configuration in an overheatingAssistanceConfig information element (IE) and stop timer T345, the instructions, when run by the processor, cause the UE to select a cell, the instructions, when run by the processor, cause the UE to perform a handover according to a stored conditional handover configuration associated with the selected cell, wherein the handover is performed based on a determination by the UE that the UE is configured with the conditional handover configuration and the selected cell is a conditional handover candidate cell indicated in a reconfigurationWithSync information element (IE) in the stored conditional handover configuration for MCG, and the instructions, when run by the processor, cause the UE to, before initiating transmission of an RRC Reestablishment Request message and based on a determination by the UE that the UE is configured with the conditional handover configuration and the selected cell is not a conditional handover candidate cell indicated in the reconfigurationWithSync IE, release the MCG SCell(s), release the special cell configuration configured in the spCellConfig IE, release the configuration in the delayBudgetReportingConfig IE and stop timer T342, and release the configuration in the overheatingAssistanceConfig IE and stop timer T345.
