1. A method performed by a terminal supporting dual connectivity in a communication system, the method comprising:
receiving a radio resource control (RRC) message for secondary cell (SCell) configuration of at least one SCell, the RRC message including information indicating whether each of the at least one SCell is activated upon the SCell configuration;
identifying, based on the information, that a state of a first SCell of the at least one SCell is activated based on the RRC message for SCell configuration;
reporting, after a first time period from a time of reception of the RRC message, first channel status information (CSI) for the first SCell based on identifying that the state of the first SCell is activated based on the RRC message for SCell configuration;
receiving a medium access control (MAC) control element (CE) to activate a second SCell of the at least one SCell in case that a state of the second SCell is deactivated; and
reporting, after a second time period, second CSI for the second SCell from a time of reception of the MAC CE,
wherein the second time period is smaller than the first time period.
