Secondary carrier activation/deactivation method and apparatus for mobile communication system supporting carrier aggregation

摘要

A method for activating/deactivating secondary carriers of a User Equipment (UE) in a mobile communication system supporting carrier aggregation is provided. The method comprises, receiving a control message including an activation/deactivation Control Element (CE) in a first sub-frame from a Base station, identifying an activation command or a deactivation command of at least one secondary carrier based on the control message, determining whether a current sub-frame is a second sub-frame or not, performing at least one first operation for the at least one secondary carrier in a second sub-frame, and performing, when the activation/deactivation CE indicates deactivation of the at least one secondary carrier, at least one second operation for the at least one secondary carrier no later than the second sub-frame.
