Joint Coordinated Multicell Processing and MIMO: Selection of Base Stations and Gain
In this paper, the authors 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. They show by simulation, that even for 4 ? 4 MIMO transmission, the CoMP can improve the spectral efficiency for some mobiles, depending on capacity outage requirements.
