We address the inter-cell interference coordination for the indoor multi-color visible light communication (VLC) network under lighting constraints. In the multi-color VLC system, soft frequency reuse-based interference coordination is adopted, which adjusts the AC powers of the cell-edge components and the cell-center components. To further improve the system throughput in the environment of dense LED deployment, we propose the dynamic scheduler for the inter-cell interference coordination. The dynamic scheduler comprises of two separate parts: the distributed algorithm that adjusts the power allocation and prepares the list of color resource usage restrictions in the neighboring cells, and the centralized algorithm that resolves the color conflicts and allocates the color resources in the network. Numerical results show the performance gain of the proposed dynamic scheduler for the cell-edge user equipments (UE).
