摘要：Improving cell-edge multi-user performance in 3GPP Long Term Evolution- Advanced networks is becoming a serious concern for the next generation wireless networks. This paper proposes Base Station Coordination as a promising solution to tackle Inter-Cell Interference especially for users located at the cell border. The cell- edge spectral efficiency is actually a more important performance index in practice due to the high-speed transmission expected in all the coverage area of a modern cellular network. Considering the preciousness of resources, our paper provides a better idea to work towards developing a new downlink and uplink transmission scheme, which could allow multi-user transmissions on the same resource to increase the utilization efficiency. We apply the pre-coding on the coordinated evolved Node B to achieve simultaneous multi-user transmissions on the same frequency band. The pre-coding matrix designed is investigated and results show that Zero-forcing pre- coding of Base Station Coordination reaches significant capacity enhancement compared to the conventional network in case of a relatively high Signal-to-Noise- Ratio.
