A METHOD AND APPARATUS OF CONTROLLING CELL DEACTIVATION IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention is directed to a wireless communication system. Specifically, the present invention is directed to a method of receiving information at a user equipment configured with a serving cell in a mobile communication system, and the method comprises activating the serving cell; receiving a first signal from a base station, the first signal including timing advance group assignment information for the serving cell; and deactivating the serving cell if the timing advance group assignment information indicates a second timing advance group different from a first timing advance group assigned to the serving cell.
