Abstract: Aspects of the disclosure provide a method to activate secondary cell group (SCG) selectively. For example, the method can include receiving a radio resource control (RRC) reconfiguration message including first and second radio resource configurations of first and second primary secondary cells (PSCells) and conditional PSCell addition (CPA) and conditional PSCell change (CPC) triggering conditions, setting a current triggering condition to be the CPA triggering condition, evaluating the current triggering condition and determining that the first PSCell satisfies the current triggering condition, and performing a CPA step to add the first PSCell as a current SCG, updating the current triggering condition to be the CPC triggering condition, the UE still keeping the first and second radio resource configurations and the CPA and CPC triggering conditions for subsequent CPC step, without releasing the second radio resource configuration and the CPA and CPC triggering conditions associated with the second PSCell.
