METHOD FOR EFFICIENTLY PERFORMING INITIAL ACCESS IN A MULTI-CARRIER BROADBAND WIRELESS ACCESS SYSTEM

摘要

A method for efficiently performing an initial access in an MS in a multi-carrier broadband wireless access system is disclosed. The method includes scanning a plurality of carriers supported by a BS, and selecting one of the scanned carriers as a first carrier and receiving an SFH of the first carrier. The SFH of the first carrier includes at least one of a field indicating load status of the first carrier and recommended network entry carrier information including information about a second carrier in good load status.

1. A method of performing a network entry procedure by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, by the UE, multi-carrier configuration information through a primary carrier configured for the UE, the multi-carrier configuration information comprising information related to at least one secondary carrier configured for the UE, the primary carrier being configured to perform a network entry procedure, the at least one secondary carrier being different from the primary carrier; receiving scheduling information for a traffic transmission on a secondary carrier of the at least one secondary carrier through the primary carrier; transmitting a traffic through the secondary carrier according to the scheduling information, receiving, by the UE, mobility control information through the primary carrier, the mobility control information including information related to a carrier frequency of a changed primary carrier; performing, by the UE, the network entry procedure via the changed primary carrier, wherein the primary carrier is changed with the network entry procedure, and wherein the primary carrier is configured to schedule the traffic transmission on the secondary carrier, and the secondary carrier is used to transmit the traffic according to the traffic transmission schedule configured by the primary carrier.
