Abstract

A method for wireless communication includes receiving an indication of unused first tier spectrum resources to determine second tier spectrum resources available for use by a second tier system. The method also includes determining third tier spectrum resources available for use a third tier system based on unused second tier spectrum resources.

Claims

1. A method for wireless communication, comprising:

receiving, at a spectrum controller, an indication of unused first tier spectrum resources to determine second tier spectrum resources available for use by at least one second tier system; and

determining, at the spectrum controller, third tier spectrum resources available for use by at least one third tier system based at least in part on unused second tier spectrum resources.

2. The method of claim 1, further comprising transmitting an indication of the third tier spectrum resources available for use by the at least one third tier system to a third spectrum tier controller.

3. The method of claim 2, in which:

first tier spectrum is specified for incumbent systems;

second tier spectrum is specified for priority access systems; and

third tier spectrum is specified for general access systems.

4. The method of claim 2, further comprising updating an amount of available third tier spectrum resources on a modified use of at least first tier spectrum resources, the second tier spectrum resources, or a combination thereof.

5. The method of claim 1, in which a second tier spectrum comprises reserved spectrum resources that are hidden from a first tier spectrum.

6. The method of claim 1, in which a second tier spectrum comprises reserved spectrum resources that are hidden from a third tier spectrum.

7. The method of claim 1, further comprising receiving spectrum information from the at least one second tier system to determine the second tier spectrum resources used by the at least one second tier system.

8. The method of claim 1, further comprising allocating spectrum resources between at least one of the at least one third tier system, the at least one second tier system, at least one first tier system, or a combination thereof based at least in part on a spectrum management scheme.

9. The method of claim 8, in which spectrum resource allocation is based at least in part on boundaries of resources between systems or a dynamic allocation.

10. The method of claim 1, in which unused spectrum resources in a specific tier are determined based at least in part on reports received from systems operating in the specific tier.

11. The method of claim 1, in which unused spectrum resources of a specific tier are determined based at least in part on radio measurements.

12. The method of claim 11, in which different radio characteristics are assigned to systems in each tier, and a specific spectrum resource used by the specific tier is identified based at least in part on the radio measurements of the specific spectrum resource that is using the assigned radio characteristics.

13. The method of claim 12, in which the radio characteristics comprise at least a radio access technology (RAT), carrier frequency, transmission bandwidth, a specific waveform or sequence that identifies the specific tier, or a combination thereof.

14. An apparatus for wireless communication, the apparatus comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor configured;

to receive, at a spectrum controller, an indication of unused first tier spectrum resources to determine second tier spectrum resources available for use by at least one second tier system; and

to determine, at the spectrum controller, third tier spectrum resources available for use by at least one third tier system based at least in part on unused second tier spectrum resources.

15. The apparatus of claim 14, in which the at least one processor is further configured to transmit an indication of the third tier spectrum resources available for use by the at least one third tier system to a third spectrum tier controller.

16. The apparatus of claim 15, in which:

first tier spectrum is specified for incumbent systems;

second tier spectrum is specified for priority access systems; and

third tier spectrum is specified for general access systems.

17. The apparatus of claim 15, in which the at least one processor is further configured to update an amount of available third tier spectrum resources on a modified use of at least first tier spectrum resources, the second tier spectrum resources, or a combination thereof.

18. The apparatus of claim 14, in which a second tier spectrum comprises reserved spectrum resources that are hidden from a first tier spectrum.

19. The apparatus of claim 14, in which a second tier spectrum comprises reserved spectrum resources that are hidden from a third tier spectrum.

20. The apparatus of claim 14, in which the at least one processor is further configured to receive spectrum information from the at least one second tier system to determine the second tier spectrum resources used by the at least one second tier system.

21. The apparatus of claim 14, in which the at least one processor is further configured to allocate spectrum resources between at least one of the at least one third tier system, the at least one second tier system, at least one first tier system, or a combination thereof based at least in part on a spectrum management scheme.

22. The apparatus of claim 21, in which spectrum resource allocation is based at least in part on boundaries of resources between systems or a dynamic allocation.

23. The apparatus of claim 14, in which unused spectrum resources in a specific tier are determined based at least in part on a reports received from systems operating in the specific tier.

24. The apparatus of claim 14, in which unused spectrum resources of a specific tier are determined based at least in part on radio measurements.

25. The apparatus of claim 24, in which different radio characteristics are assigned to systems in each tier, and a specific spectrum resource used by the specific tier is identified based at least in part on the radio measurements of the specific spectrum resource that is using the assigned radio characteristics.

26. The apparatus of claim 25, in which the radio characteristics comprise at least a radio access technology (RAT), carrier frequency, transmission bandwidth, a specific waveform or sequence that identifies the specific tier, or a combination thereof.

27. An apparatus for wireless communication, comprising:

means for receiving, at a spectrum controller, an indication of unused first tier spectrum resources to determine second tier spectrum resources available for use by at least one second tier system; and

means for determining, at the spectrum controller, third tier spectrum resources available for use by at least one third tier system based at least in part on unused second tier spectrum resources.

28. A computer program product for wireless communications, the computer program product comprising:

a non-transitory computer-readable medium having program code recorded thereon, the program code being executed by a processor and comprising;

program code to receive, at a spectrum controller, an indication of unused first tier spectrum resources to determine second tier spectrum resources available for use by at least one second tier system; and

program code to determine, at the spectrum controller, third tier spectrum resources available for use by at least one third tier system based at least in part on unused second tier spectrum resources.
