Abstract: MIMO has grown beyond the original point-to-point channel and nowadays refers to a diverse range of centralized and distributed deployments. Numerous techniques have been developed in the last decade for MIMO wireless networks, including among others Multiuser-MIMO (MUMIMO), CoMP, Massive MIMO, Non-Orthogonal Multiple Access (NOMA), millimetre wave (mmwave) MIMO. All those techniques rely on two extreme interference management strategies, namely fully decode interference and treat interference as noise. Indeed, while NOMA based on superposition coding with Successive Interference Cancellation (SIC) relies on strong users to fully decode and cancel interference created by weaker users, MU-MIMO/Massive MIMO/CoMP/mmwave MIMO based on linear precoding rely on fully treating any residual multi-user interference as noise. In the presence of imperfect channel state information at the transmitter (CSIT), CSIT inaccuracy results in additional multi-user interference that is treated as noise by all those techniques.

To efficiently cope with the high throughput, reliability, heterogeneity of Quality-of-Service (QoS), and massive connectivity requirements of future multi-antenna wireless networks, multiple access and multiuser communication system design need to depart from two conventional and extreme interference management strategies, namely fully treat interference as noise (as commonly used in 4G, MU-MIMO, CoMP, Massive MIMO, mmwave MIMO) and fully decode interference (as in NOMA).

In this tutorial, we depart from those two extremes and introduce the audience a more general, more robust, and more powerful transmission framework, namely, Rate Splitting Multiple Access (RSMA) based on linearly precoded Rate-Splitting (RS) at the transmitter and SIC receivers to decode part of the interference and treat the remaining part of the interference as noise.
