摘要：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, we propose a distributive queueaware intra-cell user scheduling and inter-cell interference (ICI) management control design for a delay-optimal celluar 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. The ICI management control is adaptive to joint queue state information (QSI) over a slow time scale, while the user scheduling control is adaptive to both the joint QSI and the joint channel state information (CSI) over a faster time scale
