Inter Cell Interference Management and Intra Cell User Scheduling in Multi Cell Networks

To achieve high spatial capacity, wireless cellular networks consider the dense deployment of Base Stations (BSs) that cover small cells. As a consequence, Inter-Cell Interference (ICI) from neighboring BSs becomes a major source of performance degradation and the portion of users whose capacity is naturally limited by ICI grows. In order to fully attain the potential gain of multi-cell networks, the coordination of transmissions among BSs which can effectively manage ICI is essential. In this paper, the authors propose a distributive queue-aware intra-cell user scheduling and Inter-Cell Interference (ICI) management control design for a delay-optimal cellular downlink system with M Base Stations (BSs), and K users in each cell. Each BS has K downlink queues for K users respectively with heterogeneous arrivals and delay requirements.
