In this paper, we provide the analysis of the downlink Coordinated Multiple Point (CoMP) used in conjunction with the basic MIMO. The CoMP is the joint multi-cell transmission from several BS to mobiles, coupled here to an open-loop MIMO technique that does not require the perfect channel state knowledge. We show by simulation, that even for $4\times 4$ MIMO transmission, the CoMP can improve the spectral efficiency for some mobiles, depending on capacity outage requirements.
