| Abstract(in English) | In our previous studies, we proposed a 2-layer IC framework based on O-RAN architecture for a cellular system with cluster-wise distributed MU-MIMO and applied a graph coloring algorithm (GCA)-based interference coordination (IC) to mitigate both the intercell interference and intracell interference. In this paper, knowing that the mobile radio environment is time-varying, we propose a joint IC consisting of a GCA-based intracell IC and a deep reinforcement learning (DRL)-based intercell IC in our 2-layer IC framework. The simulation results of our proposed joint IC have revealed that it could achieve a significant increase in capacity compared to the no IC case. |
