    Abstract

    Distributed multi-input multi-output (MIMO) provides a good transmission quality over a macro-cell area. However, the cell-edge user equipments (UEs) still suffer from strong inter-cell interference (ICI) from surrounding macro-cells and hence, their transmission quality degrades compared to the cell-center UEs. In order to mitigate the ICI problem, in this paper, we propose a de-centralized adaptive 2-step ICI coordination (ICIC) based on fractional frequency reuse (FFR). Adaptive 2-step ICIC consists of the UE classification into cell-center UEs and cell-edge UEs and the adaptive selection of fractional bands.
