In this paper, the authors address the joint problem of traffic scheduling and interference management related to the deployment of Small Cell Networks (SCNs). The base stations of the SCNs (which they will refer to as Micro Base Stations, MBSs) are low power devices with limited buffer size. They are connected to a Central Scheduler (CS) with limited capacity backhaul links. In this scenario, traffic has to be scheduled from the network to the MBS queues in such a way that the queue-length at MBS remains as close as possible to a given target queue-length. The challenge is to design a scheduler which is oblivious to the wireless link between the MBSs and the User Terminals (UTs).
