APPARATUS AND METHOD FOR SUPPORTING HANDOVER IN A MULTI-CARRIER COMMUNICATION SYSTEM

摘要

The present invention relates to an apparatus and method for supporting handover in a communication system using a multi-carrier approach. The method includes transmitting a handover request message to a serving base station (BS) through a first carrier; receiving a handover response message including neighboring base station information and temporary carrier information capable of performing a handover procedure from the serving base station through the first carrier; selecting a target base station (BS) through the neighboring base station information received from the serving base station; transmitting a handover (HO) indication message indicating a handover to the target base station to the serving base station through the first carrier; transmitting a ranging request message for synchronizing an uplink channel with the target base station to the target base station through the temporary carrier; and receiving a ranging response message from the target base station.
