Coordinated multi-point processing (CoMP) at multiple base stations has been proposed as a promising technology for improving spectral efficiency, coverage, and cell-edge throughput for future cellular systems. The basic idea of CoMP is to allow multiple base stations to cooperate via backhaul links to enhance the reliability of the links between mobile user and the serving base station. The inter-cell interference, which usually degrades wireless transmissions, can then be exploited to benefit the transmissions in the case of multicell systems in CoMP. In this paper, we will introduce two recently proposed CoMP strategies for uplink and downlink MIMO cellular systems.
