METHOD AND APPARATUS FOR ACTIVATING CARRIERS IN MOBILE COMMUNICATION SYSTEM

摘要

A method is provided for activating a carrier by a User Equipment (UE) in a mobile communication system supporting carrier aggregation. The UE receives a Down-Link (DL) assignment from an Evolved Node B (ENB), and determines whether to activate a carrier based on the DL assignment. By doing so, the UE may perform carrier activation rapidly and efficiently.
