METHOD AND APPARATUS FOR RANDOM ACCESS IN A WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method and to an apparatus for random access in a wireless communication system to which carrier aggregation is applied. According to one aspect of the present invention, a method in which a base station supports random access of a terminal in a wireless communication system that supports carrier aggregation, comprises a step in which the base station allocates, to the terminal, a dedicated PRACH preamble for a second random access in an uplink component carrier (hereinafter, referred to as "UL CC") which is additionally allocated or the configuration of which is changed after a first random access, and receives the dedicated PRACH preamble from the terminal.
