Abstract

Accordingly, a method and apparatus are provided that use implicit deassignment, 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 managing assignments of one or more communication system resources, the method comprising acts of:

transmitting an assignment indication, said assignment indication comprising a resource assignment that conflicts with a current assignment of the resource.

2. The method as claimed in claim 1, further comprising act of determining, prior to said act of transmitting, if said assignment indication can be transmitted without transmitting a deassignment indication for de-assigning assigned resources.

3. The method as claimed in claim 2, wherein said act of determining comprises an act of determining if all the recipients of said assignment indication are within a predetermined range.

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

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

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

7. The method as claimed in claim 3, further comprising act of determining required transmit power prior to said act of transmitting said assignment indication.

8. A apparatus for managing assignments of one or more communication system resources, the apparatus comprising:

means for transmitting an assignment indication, said assignment indication comprising a resource assignment that conflicts with a current assignment of the resource.

9. The apparatus as claimed in claim 8, further comprising means for determining, prior to said means for transmitting, if said assignment indication can be transmitted without transmitting a deassignment indication for de-assigning assigned resources.

10. The apparatus as claimed in claim 9, wherein said means for determining comprises means for determining if all the recipients of said assignment indication are within a predetermined range.

11. The apparatus as claimed in claim 8, wherein said means for transmitting comprises means for transmitting said assignment to said first terminal and said new recipient terminal.

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

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

14. The apparatus as claimed in claim 8, wherein said means for transmitting further comprising means for transmitting in accordance with an Orthogonal Frequency Division Multiple Access (OFDMA) scheme.

15. The method as claimed in claim 10, further comprising means for determining required transmit power prior to said act of transmitting said assignment indication.

16. In a wireless communication, an apparatus comprising:

an electronic device, said electronic device configured to transmit an assignment indication, said assignment indication comprising a resource assignment that conflicts with a current assignment of the resource.

17. The apparatus as claimed in claim 16, wherein said electronic device further configured to determine, prior to transmitting said assignment indication, if said assignment indication can be transmitted without transmitting a deassignment indication for de-assigning assigned resources.

18. The apparatus as claimed in claim 17, wherein said electronic device further configured to determine if all the recipients of said assignment indication are within a predetermined range.

19. The apparatus as claimed in claim 16, wherein said electronic device further configured to transmit said assignment to said first terminal and said new recipient terminal.

20. The apparatus as claimed in claim 16, wherein said electronic device further configured to transmit in accordance with a Code Division Multiplex Access (CDMA) scheme.

21. The apparatus as claimed in claim 16, wherein said electronic device further configured to transmit in accordance with an Orthogonal Frequency Division Multiplex (OFDM) scheme.

22. The apparatus as claimed in claim 16, wherein said electronic device further configured to transmit in accordance with an Orthogonal Frequency Division Multiple Access (OFDMA) scheme.

23. The apparatus as claimed in claim 18, wherein said electronic device further configured to determine required transmit power prior to said act of transmitting said assignment indication.

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

transmitting an assignment indication, said assignment indication comprising a resource assignment that conflicts with a current assignment of the resource.

25. The machine-readable medium of claim 24, further comprising machine readable instruction to cause determining, if said assignment indication can be transmitted without transmitting a deassignment indication for de-assigning assigned resources.

26. The machine-readable medium as claimed in claim 25, wherein said machine readable instruction to cause determining if all the recipients of said assignment indication are within a predetermined range.

27. The machine-readable medium as claimed in claim 24, wherein said machine readable instruction to cause transmitting comprises of transmitting said assignment to said first terminal and said new recipient terminal.

28. A machine-readable medium of claim 24, further comprising machine readable instruction to cause adjusting transmit power prior to transmitting said assignment indication.
