Abstract: Provided is a method and an apparatus for for changing or controlling a state of a secondary cell in carrier aggregation. The method includes receiving secondary cell (SCell) state indication information indicating a state for a SCell from a base station through an RRC message or an MAC control element, causing a state of the SCell to transition into a dormant state when the SCell state indication information indicates the dormant state, and transmitting channel state information reporting for the SCell in the dormant state according to an dormant state CQI report period parameter set separately from an activation state CQI report period parameter.

Abstract: Provided as a method and an apparatus for controlling a connection status of a UE. The method includes receiving specific RRC status instruction information for a UE from a mobility management entity (MME) and determining a RRC status for the UE based on the specific RRC status instruction information when the RRC status for the UE is changed, in which the specific RRC status is different from a RRC connection status and a RRC idle status.

Abstract: Provided are apparatus and method for communication in a non-terrestrial network (NTN). The method may include: receiving, from a base station, HARQ process activation indication information indicating whether to activate an HARQ process operation; determining whether to perform the HARQ process operation for a downlink signal on the basis of information included in the downlink signal when the downlink signal is received from the base station if the HARQ process operation deactivation is configured by the HARQ process activation indication information; and transmitting, to the base station, feedback information for the downlink signal when performing the HARQ process operation for the downlink signal is determined.
