| Abstract(in English) | Base Station Cooperation (BSC) is one of the key technologies for next generation cellular systems. In this paper, we will optimize base station antenna directivity for BSC cellular systems. In conventional systems, antenna directivity is designed to maximize the power of its own cell while minimizing the power from adjacent cells to reduce Inter-Cell Interference (ICI). However, since the problem of ICI is removed in the BSC system, base station antenna directivity is required to be designed differently from the conventional way. For the perspective, an objective function to maximize average channel capacity of cooperative cell is defined, and the optimal base station antenna directivity, i.e. beam tilt angle in vertical plane and beam width in horizontal plane, is derived by solving the corresponding optimization problem. We also propose optimal sector shape for BSC systems with designed antenna directivity that maximize the gain of cooperation. |
