Abstract

A method and apparatus for performing a carrier management in a broadband wireless communication system supporting multi-carriers are discussed. According to an embodiment, a method for a mobile station to perform a carrier management procedure with a base station supporting multiple carriers, includes receiving, by the mobile station from the base station, an instruction for a primary carrier change; transmitting, by the mobile station to the base station, an acknowledgement message indicating that the instruction is successfully received; and changing, at a specific time, a current primary carrier to one of the multiple carriers within the base station, wherein the specific time is determined based on the instruction.

Claims

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

receiving, by the mobile station from the base station, an instruction for a primary carrier change;

transmitting, by the mobile station to the base station, an acknowledgement message indicating that the instruction is successfully received; and

changing, at a specific time, a current primary carrier to one of the multiple carriers within the base station,

wherein the specific time is determined based on the instruction,

wherein the instruction further includes an action time, and the specific time is determined according to the action time, and

wherein the action time is set to a value more than a retransmission time for the instruction.

2. The method according to claim 1, wherein the retransmission timer is set to a time during which the base station waits for receiving the acknowledgement message in response to the carrier management command message.

3. The method according to claim 1, wherein the instruction includes an action code, and

the action code indicates the primary carrier change.

4. The method according to claim 1, wherein the instruction is received on the current primary carrier.

5. The method according to claim 1, wherein the acknowledgement message is transmitted on the current primary carrier.

6. The method according to claim 1, wherein the one of the multiple carriers is a target carrier, and

the target carrier is determined according to the instruction.

7. The method according to claim 1, wherein a control signal on the current primary carrier is disconnected at the specific time.

8. The method according to claim 1, wherein the instruction from the base station is an AAI-CM-CMD (Advanced Air Interface-Carrier Management-COMMAND) message.

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

transmitting, by the base station to the mobile station, an instruction for a primary carrier change; and

receiving, by the base station from the mobile station, an acknowledgement message indicating that the instruction is successfully received at the mobile station,

wherein a current primary carrier at the mobile station is changed to one of the multiple carriers within the base station,

wherein the specific time is determined based on the instruction,

wherein the instruction further includes an action time, and the specific time is determined according to the action time, and

wherein the action time is set to a value more than a retransmission timer for the instruction.

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

a receiver;

a transmitter; and

a processor,

wherein the processor is configured to;

receive, using the receiver from the base station, an instruction for a primary carrier change;

transmit, using the transmitter to the base station, an acknowledgement message indicating that the instruction is successfully received; and

change, at a specific time, a current primary carrier to one of the multiple carriers within the base station,

wherein the specific time is determined based on the instruction,

wherein the instruction further includes an action time, and the specific time is determined according to the action time, and

wherein the action time is set to a value more than a retransmission timer for the instruction.

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

a receiver;

a transmitter; and

a processor,

wherein the processor is configured to;

transmit, using the transmitter to the mobile station, an instruction for a primary carrier change; and

receive, using the receiver from the mobile station, an acknowledgement message indicating that the instruction is successfully received at the mobile station,

wherein a current primary carrier at the mobile station is changed to one of the multiple carriers within the base station,

wherein the specific time is determined based on the instruction,

wherein the instruction further includes an action time, and the specific time is determined according to the action time, and

wherein the action time is set to a value more than a retransmission timer for the instruction.
