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.

主权项

1. A method for activating/deactivating at least one secondary carrier of a terminal in a mobile communication system supporting carrier aggregation, the method comprising:
identifying, when information associated with secondary carrier control is received from a base station, an activation command or a deactivation command of the at least one secondary carrier in the information associated with secondary carrier control; executing, when the information associated with secondary carrier control indicates the activation command of the at least one secondary carrier, at least one of channel state information report, physical downlink control channel monitoring on secondary carriers, and sounding reference signal transmission in a first sub-frame; and executing, when the information associated with secondary carrier control indicates the deactivation command of at least one secondary carrier, at least one of physical downlink control channel monitoring termination on secondary carriers and sounding reference signal transmission termination no later than the first sub-frame and a channel state information report termination in the first sub-frame.
