In LTE-Advanced (Long Term Evolution-Advanced), HetNet (heterogeneous network) is studied intensively for the explosive mobile traffic increase. In HetNet, small cells are overlaid on top of a macro cell. If HetNet is applied to an urban area, where mobile traffic is heavily loaded, many indoor small cells have to be placed in not 2D but 3D spaces as there are so many tall buildings in the area. In this “3D cell structure”, it is necessary to suppress not only the interference between an indoor small cell and an outdoor macro cell, but also the interference between indoor small cells. We proposed a novel control method to suppress inter-cell interference, in which base stations are coordinated over an IP backhaul network. This method is based on LTE-Advanced and all outdoor macro cells and all indoor small cells are linked by the backhaul network. In order to realize the proposed system, the base stations must be synchronized accurately and the transmission delay of backhaul network is minimized. In this paper, we propose an implementation method to minimize the transmission delay of backhaul network. The proposed method is evaluated experimentally to show the delay performance improvement. |
