Method and system for inter-cell interference coordination in wireless networks

A non-transitory computer-readable storage medium storing instructions which when executed by at least one processor of a small cell gateway enables the at least one processor to execute a method of managing inter-cell interference in a wireless network, the method comprising:

• receiving, by the at least one processor, uplink interference power corresponding to a first small cell base station (SCBS);
• receiving, by the at least one processor, neighboring cell information of the first SCBS, the neighboring cell information including information on a first plurality of SCBSs neighboring the first SCBS;
• determining, by the at least one processor, based on the received uplink interference power, that the first SCBS is experiencing inter-cell interference;
• in response to determining that the first SCBS is experiencing inter-cell interference, determining, by the at least one processor, a second plurality of SCBSs from among the first plurality of SCBSs that are interfering with the first SCBS;
• and
• adjusting, by the at least one processor, uplink power allocation corresponding to a second SCBS from among the second plurality of SCBSs,
• wherein receiving uplink interference power corresponding to the first SCBS includes receiving uplink interference power for each of a plurality of physical resource blocks in the first SCBS uplink bandwidth.

A system implemented at a small cell gateway for managing inter-cell interference in a wireless network, the system comprising:

• a memory storing instructions;
• and
• at least one processor configured by the instructions to:
• receive uplink interference power corresponding to a first small cell base station (SCBS);
• receive neighboring cell information of the first SCBS, the neighboring cell information including information on a first plurality of SCBSs neighboring the first SCBS;
• determine based on the received uplink interference power, that the first SCBS is experiencing inter-cell interference;
• in response to determining that the first SCBS is experiencing inter-cell interference, determine a second plurality of SCBSs from among the first plurality of SCBSs that are interfering with the first SCBS;
• and
• adjust uplink power allocation corresponding to a second SCBS from among the second plurality of SCBSs,
• wherein receiving uplink interference power corresponding to the first SCBS includes receiving uplink interference power for each of a plurality of physical resource blocks in the first SCBS uplink bandwidth.
