Abstract:
The present invention proposes a method of sending a UE the timing advance information per carrier group promptly and commanding preamble transmission, and activating secondary carriers in a wireless communication system supporting carrier aggregation technology using uplink transmission timings for the respective carrier groups. Through the present invention, the UE is capable of configuring the timing advance information of the carrier group promptly and activating the secondary carrier quickly, resulting in reduction of uplink transmission delay.
