1. A method performed by a terminal in a wireless communication system, the method comprising:
transmitting a capability information including information indicating whether the terminal supports conditional primary secondary cell (PSCell) change;
receiving a radio resource control (RRC) reconfiguration message including condition information for the conditional PSCell change for a secondary node (SN);
transmitting an RRC reconfiguration complete message as a response to the RRC reconfiguration message;
performing actions related to the conditional PSCell change based on the condition information for the conditional PSCell change; and
transmitting a secondary cell group (SCG) failure information including an identity of a PSCell associated with a failure of the conditional PSCell change, in case that the failure of the conditional PSCell change is identified.
