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.

Mitigation of uplink interference within heterogeneous wireless communications networks

In one example embodiment, a method for classifying a basestation in a cellular communications network is provided that may include obtaining an identifier used by the basestation, comparing the identifier to a pool of identifiers reserved for a class of basestations, obtaining a frequency on which the basestation is operating, comparing the frequency to a pool of frequencies used by the class of basestations, and identifying the basestation as belonging to the class of basestations if the identifier is in the pool of identifiers and the frequency is in the pool of frequencies. Another method for classifying a basestation may comprise receiving a broadcast from the basestation including an attribute of the basestation, comparing the attribute with an attribute value range corresponding to the class of basestations, and identifying the basestation as belonging to the class of basestations if the received cell attribute falls within the attribute value range.

Classification of a basestation

In one embodiment, a method of forming a neighbor cell list in a base station of a cellular communications network comprises, at periodic intervals, and for specified durations: requesting the or each wireless device that is in connected mode with the base station to report a unique identifier for each other base station that it is able to detect; receiving reports from the or each wireless device that is in connected mode with the base station; and operating with a neighbor cell list compiled on the basis of the received reports.
