Techniques to assign identifiers in a wireless network

1. A method comprising:

assigning, by a base station, a first identifier to a multi-carrier mobile station for communicating on first and second carriers of the base station;

assigning the first identifier to a first single-carrier mobile station for communicating on a third carrier of the base station; and

when the third carrier is added to the multi-carrier mobile station:

reassigning the first identifier to a second single-carrier mobile station for communicating on either the first carrier or the second carrier; and

assigning a second identifier to the multi-carrier mobile station for communicating on the first, second, and third carriers.

2. The method of claim 1 , wherein the assigning the first identifier to the first single-carrier mobile station takes place in response to the first single-carrier mobile station entering or re-entering a cell.

3. The method of claim 1 , wherein the first identifier and the second identifier both comprise station identifiers.

4. A method comprising:

receiving, by a multi-carrier mobile station, an assignment of a first identifier on first and second carriers of a multi-carrier base station;

adding a third carrier of the multi-carrier base station; and

when the first identifier has been assigned to another mobile station for communicating on the third carrier:

receiving an assignment of a second identifier; and

communicating on the first, second, and third carriers using the second identifier.

5. The method of claim 4 , further comprising:

applying the first identifier for media access control communications.

6. The method of claim 4 , wherein the first identifier and the second identifier both comprise station identifiers.

7. The method of claim 4 , comprising, when the first identifier has not been assigned to another mobile station for communicating on the third carrier, communicating on the first, second, and third carriers using the first identifier.

8. A mobile station comprising:

a processor circuit;

a media access control (MAC) logic;

logic for execution by the processor circuit to access an assignment of a first identifier to the mobile station for communicating on first and second carriers of a multi-carrier base station;

logic for execution by the processor circuit to add a third carrier of the multi-carrier base station; and

logic for execution by the processor circuit to, when the first identifier has been assigned to another mobile station for communicating on the third carrier:

access an assignment of a second identifier; and

communicate on the first, second, and third carriers using the second identifier.

9. The apparatus of claim 8 , wherein the first identifier and the second identifier both comprise station identifiers.

10. The apparatus of claim 8 , further comprising logic to use the first identifier on the first carrier as an identifier for use on the second carrier without receipt of an assignment of another identifier for use on the second carrier in response to the mobile station operating as a multi-carrier mobile station.

11. The apparatus of claim 8 , further comprising:

logic to apply the first identifier for media access control communications.

12. The mobile station of claim 8 , comprising logic for execution by the processor circuit to, when the first identifier has not been assigned to another mobile station for communicating on the third carrier, communicate on the first, second, and third carriers using the first identifier.

13. A system comprising:

a display device;

a radio; and

a host system comprising:

a media access control (MAC) logic,

logic to access an assignment of a first identifier to the system for use to communicate over first and second carriers of a multi-carrier base station;

logic to add a third carrier of the multi-carrier base station; and

logic to, when the first identifier has been assigned to another system for use to communicate over the third carrier:

access a reassignment of the first identifier; and

communicate on the first, second, and third carriers using the second identifier.

14. The system of claim 13 , further comprising:

logic to apply the first identifier for media access control communications.

15. The system of claim 13 , further comprising logic to use the first identifier on the first carrier as an identifier for use on the second carrier without receipt of another assignment of an identifier for use on the second carrier in response to the system operating as a multi-carrier mobile station.

16. The system of claim 13 , wherein the first identifier and the second identifier both comprise station identifiers.

17. The system of claim 13 , the host system comprising logic to, when the first identifier has not been assigned to another system for use to communicate over the third carrier, communicate over the first, second, and third carriers using the first identifier.
