Mitigation of uplink interference within heterogeneous wireless communications networks
First Claim
1. A method comprising:
- gathering at a small cell base station information to populate a neighbor cell list of the small cell base station;
gathering measurement reports from connected mode user equipment (“
UE”
) at the small cell base station; and
in response to determining that uplink interference has exceeded a predetermined threshold, generating an alarm to a central node to trigger an action performed by the central node on an aggressor node, wherein the aggressor node is different from the small cell base station and services an aggressor UE, wherein the aggressor UE is determined from the gathered information and the gathered measurement reports to contribute to the uplink interference.

Abstract
A method is provided in one example embodiment and includes gathering at a small cell base station information to populate a neighbor cell list of the small cell base station; gathering measurement reports from connected mode user equipment (“UE”) at the small cell base station; and determining whether uplink interference has exceeded a predetermined threshold and generating an alarm to a central node when the uplink interference has exceeded the predetermined threshold. Upon receipt of notification, the central node triggers an action on an aggressor node, wherein the aggressor node is a node servicing at least one aggressor user equipment (“UE”) that significantly contributes to the uplink interference as determined from the gathered information and reports.

9. One or more non-transitory tangible media having encoded thereon logic that includes code for execution and when executed by a processor is operable to perform operations comprising:
-
gathering at a small cell base station information to populate a neighbor cell list of the small cell base station; gathering measurement reports from connected mode user equipment (“
UE”
) at the small cell base station; andin response to determining that an uplink interference has exceeded a predetermined threshold, generating an alarm to a central node to trigger an action performed by the central node on an aggressor node, wherein the aggressor node is different from the small cell base station and services an aggressor UE, wherein the aggressor UE is determined from the gathered information and the gathered measurement reports to contribute to the uplink interference. - View Dependent Claims (10, 11, 12, 13, 14)

15. An apparatus comprising:
-
a memory element configured to store data; a processor operable to execute instructions associated with the data; and an interference mitigation module configured to; gather at a small cell base station information to populate a neighbor cell list of the small cell base station; gather measurement reports from connected mode user equipment (“
UE”
) at the small cell base station; andin response to determining that an uplink interference has exceeded a predetermined threshold, generate an alarm to a central node to trigger an action performed by the central node on an aggressor node, wherein the aggressor node is different from the small cell base station and services an aggressor UE, wherein the aggressor UE is determined from the gathered information and the gathered measurement reports to contribute to the uplink interference. - View Dependent Claims (16, 17, 18, 19, 20)
