Abstract

Coordinated multi-cell multi-antenna transmission can effectively mitigate inter-cell interference in cellular MIMO systems, thus improving cell edge throughput. However, the performance heavily depends on the channel state information and cooperation among multiple base stations. In this paper, we investigate
the impact of limited feedback on the multi-cell local joint precoding based on 2-cell cooperative transmission. According to the location of cell edge users, we propose a multi-mode transmission method. Simulation results show that it can significantly enhance cell edge throughput.

Key words： MIMO,; multi-cell,; limited feedback,; cell edge throughput
