Since data rates for cell-edge users cannot be improved by merely increasing transmission power due to inter-cell interference (ICI), the interference management and alignment become crucial for cell-edge users. In this paper, we consider a simple approach where each base station (BS) in coordination transmits signals to a dedicated user through multiple subcarriers shared by adjacent BSs so that a higher diversity can be exploited for a better performance through joint detection.
