TY  - JOUR
AB  - MIMO processing plays a central part towards the recent increase in spectraland energy efficiencies of wireless networks. MIMO has grown beyond theoriginal point-to-point channel and nowadays refers to a diverse range ofcentralized and distributed deployments. The fundamental bottleneck towardsenormous spectral and energy efficiency benefits in multiuser MIMO networkslies in a huge demand for accurate channel state information at the transmitter(CSIT). This has become increasingly difficult to satisfy due to the increasingnumber of antennas and access points in next generation wireless networksrelying on dense heterogeneous networks and transmitters equipped with a largenumber of antennas. CSIT inaccuracy results in a multi-user interferenceproblem that is the primary bottleneck of MIMO wireless networks. Lookingbackward, the problem has been to strive to apply techniques designed forperfect CSIT to scenarios with imperfect CSIT. In this paper, we depart fromthis conventional approach and introduce the readers to a promising strategybased on rate-splitting. Rate-splitting relies on the transmission of commonand private messages and is shown to provide significant benefits in terms ofspectral and energy efficiencies, reliability and CSI feedback overheadreduction over conventional strategies used in LTE-A and exclusively relying onprivate message transmissions. Open problems, impact on standard specificationsand operational challenges are also discussed.
