Abstract  Abstract

The present invention provides a method and apparatus for managing a plurality of timing advance groups in a wireless communication system that supports carrier aggregation. A method for managing a plurality of timing advance groups in a base station of a wireless communication system using carrier aggregation according to an embodiment of the present invention groups a plurality of carriers into a timing advance group according to a preset criterion. Assigning a timing advance group index to each timing advance group; transmitting the timing advance group index information to a terminal; generating timing advance information for synchronization; and performing the random access The method includes a step of sending advance information at the terminal.
