9. The method of claim 8, wherein the plurality of allocations is arranged in a sequential manner, wherein the sequential manner comprises a first allocation, wherein the least one allocation of the plurality of allocations that does not correspond to a terminal comprises the first allocation.

10. The method of claim 8, wherein the resource space comprises a frame, wherein each allocation of the plurality of allocations comprises a grant, wherein each resource of the apportioned plurality of resources comprises a slot.

11. The method of claim 8, wherein at least one allocation that corresponds to a terminal of the plurality of terminals comprises at least one resource used by the terminal for an uplink transmission and at least one resource not used by the terminal for an uplink transmission.

12. The method of claim 1, wherein the wireless communication system comprises a WiMAX communication system.

13. The method of claim 1, further comprising:

utilizing at least one advanced network-level algorithm or planning to minimize interference.

14. A computer program product to reduce uplink interference in a wireless communication system, the computer program product comprising program instructions embodied on a tangible computer-readable medium, execution of the program instructions resulting in operations comprising:

apportioning a plurality of resources in a resource space such that at least one resource of the plurality of resources not used for an uplink transmission from a terminal to an access node is located between a beginning of the resource space and at least one resource of the plurality of resources used for an uplink transmission with the terminal; and

informing the terminal of the resources apportioned for the uplink transmission from the terminal to the access node.

15. The computer program product of claim 14, wherein apportioning the plurality of resources comprises allocating a plurality of resources for the terminal, wherein the allocated plurality of resources comprises at least one resource used by the terminal for an uplink transmission and at least one resource not used by the terminal for an uplink transmission.

16. The computer program product of claim 15, execution of the program instructions resulting in operations further comprising:

utilizing an algorithm to select a size of the allocated plurality of resources.
