| Abstract(in English) | We propose distributed resource allocation schemes for the downlink of an OFDMA-based Macro-cell/Femtocell overlaid Heterogeneous Network (HetNet). To mitigate the interference caused by Femtocell Based Stations (FBS)s on nearby Macro Users (MU)s, the FBS estimates the subchannels likely to be used by its neighbor MUs, based on their locally overheard Channel State Information (CSI), and sets appropriate power constraints on those subchannels. We derive by analysis the subchannel allocation probability of neighboring MUs and minimize the MU allocation estimation error probability at the FBS. The simulation results show that the proposed methods efficiently mitigate the interference from FBSs to nearby MUs, providing a very good macrocell/femtocell throughput trade-off in a completely distributed manner. |
