MIMO and OFDM are considered as the dominant techniques for future wireless communication. However, there are still unsolved problem for multiuser case, especially in publice large coverage cellular system. This presentation addresses some key techniques suitable for high efficiency downlink transimission in cellular environment, which is involved in FuTURE project. The key issue we are dealing with is how to control the unexpected interference from other users and other cells, and how to mitigate the effect of mutual interference on system performance. The concept of grouping users are introduced in this paper, in order to simplify the performance optimization.
