Patent Images
1. A method by a terminal in a mobile communication system, the method including:
- receiving, by the terminal, first information for activating a secondary cell (SCell) from a base station;
activating, by the terminal, the SCell based on the first information;
starting, by the terminal, a timer associated with the SCell; and
applying, by the terminal, one or more corresponding actions for deactivating the SCell no later than in subframe n+8, if the timer expires in subframe n.

Abstract
A method and an apparatus for deactivating secondary carriers in a mobile communication system using carrier aggregation are provided. A communication method, for a User Equipment (UE), includes activating a secondary carrier, starting a first timer upon activation of the secondary carrier, starting a second timer when the first timer expires, and deactivating the activated secondary carrier when the second timer expires.
