Method for performing carrier management procedure in a multi-carrier supported wideband wireless communication system and apparatus for the same

A method for a base station supporting multiple carriers to perform carrier management procedure with a mobile station, the method comprising:

• transmitting a carrier management command message to the mobile station, the carrier management command message including an action code for carrier management and a polling bit in a MAC Control Extended Header (MCEH) indicating whether an acknowledgement message is required;
• receiving the acknowledgement message in response to the carrier management command message from the mobile station when the carrier management command message is successfully received by the mobile station and the polling bit is set to 1;
• and
• receiving a carrier management indication message, corresponding to the action code included in the carrier management command message, from the mobile station,
• wherein the action code indicates a primary carrier change or a secondary carrier management, and
• wherein, if the action code indicates the primary carrier change, the acknowledgement message in response to the carrier management command message is transmitted on a serving primary carrier of the base station, and the carrier management indication message is transmitted on a target primary carrier of the base station.

A mobile station for performing a carrier management procedure with a base station supporting multiple carriers, the mobile station comprising:

• a reception module;
• a transmission module;
• and
• a processor configured to:
• control the reception module to receive a carrier management command message from the base station, the carrier management command message including an action code for carrier management and a polling bit in a MAC Control Extended Header (MCEH) indicating whether an acknowledgement message is required,
• control the transmission module to transmit the acknowledgement message in response to the carrier management command message to the base station when the carrier management command message is successfully received and the polling bit is set to 1,
• control the mobile station to perform carrier management operation based on the carrier management command message, and
• control the transmission module to transmit a carrier management indication message, corresponding to the action code included in the carrier management command message, to the base station, and
• wherein the action code indicates primary carrier change or secondary carrier management, and
• wherein, if the action code indicates the primary carrier change, the acknowledgement message in response to the carrier management command message is transmitted on a serving primary carrier of the base station, and the carrier management indication message is transmitted on a target primary carrier of the base station.
