Abstract

Accordingly, a method and apparatus are provided that use implicit de-assignment, instead of explicit deassignment, of resources, such that a mobile terminal can interpret the assignment of the resources to other channel terminals as an implied deassignment of the resources. Thus, reducing the number of assignment or the assignment between the base station and the terminals.

Claims

1. A method of processing an assignment of one or more communication resource, the method comprising acts of:

receiving an assignment indication having an assignment of one or more newly assigned communication resource intended for a second access terminal;

determining that a conflict occurs between the one or more newly assigned communication resource intended for the second access terminal and one or more currently assigned communication resource for a first access terminal;

interpreting the conflict as an implied de-assignment of the one or more currently assigned communication resource for the first access terminal; and

terminating the use of said one or more currently assigned communication resource for the first access terminal in response to interpreting the conflict as the implied deassignment.

2. The method as claimed in claim 1, wherein the act of determining comprises an act of determining that said assignment indication indicates that the currently assigned communication resources for the first access terminal are assigned to the second access terminal.

3. The method as claimed in claim 1, wherein said act of terminating said one or more currently assigned communication resource for the first access terminal comprises an act of terminating use of only said one or more communication resources for the first access terminal that are in conflict with the newly assigned communication resource intended for the second access terminal.

4. The method as claimed in claim 1, wherein said act of terminating said one or more currently assigned communication resource for the first access terminal comprises an act of terminating use of all said one or more currently assigned communication resources for the first access terminal.

5. The method as claimed in claim 1, wherein the said act of receiving further comprising act of receiving in accordance with a Code Division Multiplex Access (CDMA) scheme.

6. The method as claimed in claim 1, wherein the said act of receiving further comprising act of receiving in accordance with an Orthogonal Frequency Division Multiplex (OFDM) scheme.

7. The method as claimed in claim 1, wherein said act of receiving further comprising act of receiving in accordance with an Orthogonal Frequency Division Multiple Access (OFDMA) scheme.

8. An apparatus for processing an assignment of one or more communication resource, the apparatus comprising:

means for receiving an assignment indication having an assignment of one or more newly assigned communication resource intended for a second access terminal;

means for determining that a conflict occurs, between the one or more newly assigned communication resource intended for the second access terminal and one or more currently assigned communication resource for a first access terminal;

means for interpreting the conflict as an implied de-assignment of the one or more currently assigned communication resource for the first access terminal; and

means for terminating the use of said one or more currently assigned communication resource for the first access terminal in response to interpreting the conflict as the implied deassignment.

9. The apparatus as claimed in claim 8, wherein the means for determining comprises means for determining that said assignment indication indicates that the currently assigned communication resources for the first access terminal are assigned to the second access terminal.

10. The apparatus as claimed in claim 8, wherein said means for terminating said one or more currently assigned communication resource for the first access terminal comprises means for terminating use of only said one or more communication resources for the first access terminal that are in conflict with the newly assigned communication resource intended for the second access terminal.

11. The apparatus as claimed in claim 8, wherein said means for terminating said one or more currently assigned communication resource for the first access terminal comprises means for terminating use of all said one or more currently assigned communication resources for the first access terminal.

12. The apparatus as claimed in claim 8, wherein the said means for receiving further comprising means for receiving in accordance with a Code Division Multiplex Access (CDMA) scheme.

13. The apparatus as claimed in claim 8, wherein the said means for receiving further comprising means for receiving in accordance with an Orthogonal Frequency Division Multiplex (OFDM) scheme.

14. The apparatus as claimed in claim 9, wherein said means for receiving further comprising means for receiving in accordance with an Orthogonal Frequency Division Multiple Access (OFDMA) scheme.

15. In a wireless communication, an apparatus comprising:

an electronic device, said electronic device configured to;

receive an assignment indication having an assignment of one or more newly assigned communication resource intended for a second access terminal;

determine that a conflict occurs between the one or more newly assigned communication resource intended for the second access terminal and one or more currently assigned communication resource for a first access terminal;

interpret the conflict as an implied de-assignment of the one or more currently assigned communication resource for the first access terminal; and

terminate the use of said one or more currently assigned communication resource for the first access terminal in response to interpreting the conflict as the implied deassignment.

16. The apparatus as claimed in claim 15, wherein said electronic device further configured to determine that said assignment indication indicates that the currently assigned communication resources for the first access terminal are assigned to the second access terminal.

17. The apparatus as claimed in claim 15, wherein said electronic device further configured to terminate use of only said one or more communication resources for the first access terminal that are in conflict with the newly assigned communication resource intended for the second access terminal.

18. The apparatus as claimed in claim 15, wherein said electronic device further configured to terminate use of all said one or more currently assigned communication resources for the first access terminal.

19. The apparatus as claimed in claim 15, wherein said electronic device further configured to receive in accordance with a Code Division Multiplex Access (CDMA) scheme.

20. The apparatus as claimed in claim 15, wherein said electronic device further configured to receive in accordance with an Orthogonal Frequency Division Multiplex (OFDM) scheme.

21. The apparatus as claimed in claim 15, wherein said electronic device further configured to receive in accordance with an Orthogonal Frequency Division Multiple Access (OFDMA) scheme.

22. A machine-readable medium comprising instructions which, when executed by a machine, cause the machine to perform operations including:

receiving an assignment indication having an assignment of one or more newly assigned communication resource intended for a second access terminal;

determining that a conflict occurs between the one or more newly assigned communication resource intended for the second access terminal and one or more currently assigned communication resource for a first access terminal;

interpreting the conflict as an implied de-assignment of the one or more currently assigned communication resource for the first access terminal; and

terminating the use of said one or more currently assigned communication resource for the first access terminal in response to interpreting the conflict as the implied deassignment.

23. The machine-readable medium as claimed in claim 22, wherein the machine readable instruction to cause determining comprises determining that said assignment indication indicates that the currently assigned communication resources for the first access terminal are assigned to the second access terminal.

24. The machine-readable medium as claimed in claim 22, wherein said machine readable instruction to cause terminating said one or more currently assigned communication resource for the first access terminal comprises terminating use of only said one or more resources that are in conflict with the received assignment of resource.
