Abstract
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.
Claims6
A method for performing a network entry at a mobile station (MS) in a wireless communication system, comprising:
- receiving, multi-carrier configuration information for available carriers, by the MS from a base station (BS);
- receiving control information by the MS from the BS,
- wherein the control information indicates that whether a specific carrier of the available carriers is a fully configured carrier or a partially configured carrier;
- performing, by the MS, the network entry on only a carrier indicated as the fully configured carrier based upon the multi-carrier configuration information and the control information;
- and
- receiving, by the MS from the BS, at least one control channel through the fully configured carrier;
- wherein the fully configured carrier is configured as a primary carrier,
- wherein the multi-carrier configuration information for available carriers comprises information of a recommended carrier, and
- wherein the recommended carrier is recommended by the BS.
A mobile station for performing a network entry in a multi-carrier broadband wireless access system, comprising:
- a radio frequency (RF) module configured to receive a multi-carrier configuration information for available carriers and control information from a base station,
- wherein the control information indicates that whether a specific carrier of the available carriers is a fully configured carrier or a partially configured carrier,
- a processor configured to control the network entry so that the network entry is performed on only a carrier configured as a type of a fully configured carrier among the available carriers based upon the multi-carrier configuration information and the control information,
- wherein the RF module is further configured to receive at least one control channel through the fully configured carrier from the base station,
- wherein the fully configured carrier is configured as a primary carrier,
- wherein the multi-carrier configuration information for available carriers comprises information of a recommended carrier, and
- wherein the recommended carrier is recommended by the base station.
