Abstract [en]

In Multiple Input Multiple Output (MIMO) communications, multiple antenna elements are employed both in the transmitter and the receiver, in order to obtain increased data rates or improved reliability compared to single-antenna transmission. In cellular systems, the Base Stations (BS) may operate in Single User (SU)-MIMO mode, i.e. to employ point-to-point transmission of data just for one multi-antenna User Equipment at a time. Alternatively, the BS can perform Multiuser (MU)-MIMO transmission, i.e. spatially multiplex data streams intended for different UEs that may be equipped with arbitrary numbers of antenna elements. The use of MU-MIMO mode offers potential system capacity gains especially when the BS employs a large antenna array. This chapter discusses various aspects of MIMO communications, with a special focus on the downlink direction of cellular systems. First, an overview of the fundamentals and existing techniques is given. Then, the MIMO related standards and standardization activities are described. Finally, some recent advances concerning MU-MIMO communications are addressed.
