CLIAMS:We claim:

1. A processor-implemented inter-cell interference coordination method, comprising:
forming, via one or more hardware processors, a common resource pool of physical resource blocks that are common across an uplink bandwidth of member base stations of an interference control group;
identifying, via the one or more hardware processors, that one of the member base stations of the interference control group is an interferer base station to a victim base station;
determining, via the one or more hardware processor, after identifying the interferer base station and the victim base station, an individual physical resource block from the common resource pool based on:
an uplink interference, having power greater than a first threshold, experienced by the victim base station for the individual resource block, and
the interferer base station having an allocated uplink power for the individual physical resource block that is greater than a second threshold; and
reducing, via the one or more hardware processors, the allocated uplink power of the interferer base station for the determined individual resource block.
2. The method of claim 31, wherein the member base stations are small-cell base stations in an LTE network.
3. The method of claim 31, wherein the first threshold and the second threshold are based on small-cell gateway operator input.
4. The method of claim 31, wherein the step of determining the individual physical resource block from the common resource pool is performed for each physical resource block of the common resource pool.
5. The method of claim 31, wherein reducing the allocated uplink power of the interferer base station for the identified individual resource block comprises:
sending to the interferer base station resource allocation information indicating that the allocated uplink power for the identified individual resource block is reduced by a predetermined factor.
6. The method of claim 35, wherein the resource allocation information is broadcast at predetermined intervals.
7. The method of claim 36, further comprising:
reassigning a physical resource block to one of the member base stations between adjacent broadcasts.
8. A inter-cell interference coordination system comprising:
one or more hardware processors; and
a computer-readable medium storing instructions that, when executed by the one or more hardware processors, cause the one or more hardware processors to perform operations comprising:
forming, via one or more hardware processors, a common resource pool of physical resource blocks that are common across an uplink bandwidth of member base stations of an interference control group;
identifying, via the one or more hardware processors, that one of the member base stations of the interference control group is an interferer base station to a victim base station;
determining, via the one or more hardware processor, after identifying the interferer base station and the victim base station, an individual physical resource block from the common resource pool based on:
an uplink interference, having power greater than a first threshold, experienced by the victim base station for the individual resource block, and
the interferer base station having an allocated uplink power for the individual physical resource block that is greater than a second threshold; and
reducing, via the one or more hardware processors, the allocated uplink power of the interferer base station for the determined individual resource block.
9. The system of claim 38, wherein the member base stations are small-cell base stations in an LTE network.
10. The system of claim 38, wherein the first threshold and the second threshold are based on small-cell gateway operator input.
11. The system of claim 38, wherein the step of determining the individual physical resource block from the common resource pool is performed for each physical resource block of the common resource pool.
12. The system of claim 38, wherein reducing the allocated uplink power of the interferer base station for the identified individual resource block comprises:
sending to the interferer base station resource allocation information indicating that the allocated uplink power for the identified individual resource block is reduced by a predetermined factor.
13. The system of claim 42, wherein the resource allocation information is broadcast at predetermined intervals.
14. A non-transitory computer-readable medium storing instructions, wherein upon execution of the instructions by one or more hardware processors, the hardware processors perform operations comprising:
forming, via one or more hardware processors, a common resource pool of physical resource blocks that are common across an uplink bandwidth of member base stations of an interference control group;
identifying, via the one or more hardware processors, that one of the member base stations of the interference control group is an interferer base station to a victim base station;
determining, via the one or more hardware processor, after identifying the interferer base station and the victim base station, an individual physical resource block from the common resource pool based on:
an uplink interference, having power greater than a first threshold, experienced by the victim base station for the individual resource block, and
the interferer base station having an allocated uplink power for the individual physical resource block that is greater than a second threshold; and
reducing, via the one or more hardware processors, the allocated uplink power of the interferer base station for the determined individual resource block.
15. The computer-readable medium of claim 44, wherein the member base stations are small-cell base stations in an LTE network.
16. The computer-readable medium of claim 44, wherein the first threshold and the second threshold are based on small-cell gateway operator input.
17. The computer-readable medium of claim 44, wherein the step of determining the individual physical resource block from the common resource pool is performed for each physical resource block of the common resource pool.
18. The computer-readable medium of claim 44, wherein reducing the allocated uplink power of the interferer base station for the identified individual resource block comprises:
sending to the interferer base station resource allocation information indicating that the allocated uplink power for the identified individual resource block is reduced by a predetermined factor.
19. The computer-readable medium of claim 48, wherein the resource allocation information is broadcast at predetermined intervals.
20. The computer-readable medium of claim 49, further comprising:
reassigning a physical resource block to one of the member base stations between adjacent broadcasts.
