In our recently study, we proposed a restricted color number-based graph coloring algorithm (RCN-GCA) for interference coordination in cluster-wise distributed MU-MIMO. The RCN-GCA aims at mitigating the inter-cluster interference and its effectiveness for improving the link capacity was verified assuming single-cell system model. In this paper, we extend our study to multi-cell cluster-wise MU-MIMO and propose a 2-step RCN-GCA. The proposed 2-step RCN-GCA is designed to coordinate not only the inter-cluster interference but also the inter-cell interference simultaneously by dividing the users into 2 groups (cell-edge and cell-center), and applying GCA separately on these two groups. The computer simulation results confirm that our proposed 2-step RCN-GCA can achieve better performance than the previous RCN-GCA in a multi-cell system. |
