A relatively recent idea of extending the benefits of MIMO systems to multiuser scenarios seems promising in the context of achieving high data rates envisioned for future cellular standards after 3G 3rd Generation . Although substantial research has been done on the theoretical front recent focus is on making Multiuser Multiple-Input Multiple-Output MUMIMO practically realizable. This paper presents an overview of the different MU-MIMO schemes included being studied in 3GPP standardization from LTE long-term evolution to LTE
