RSMA relies on the split of mess ages and the non-orthogonal transmission of common messages decoded by mul tiple users\, and private messages decoded by their corresponding users. T his enables RSMA to softly bridge and therefore reconcile the two extreme strategies of fully decode interference and treat interference as noise. R SMA has been shown to generalize\, and subsume as special cases\, four see mingly different strategies\, namely Space Division Multiple Access (SDMA) based on linear precoding (currently used in 5G)\, Orthogonal Multiple Ac cess (OMA)\, Non-Orthogonal Multiple Access (NOMA) based on linearly preco ded superposition coding with SIC\, and physical-layer multicasting. RSMA boils down to those strategies in some specific conditions\, but outperfor ms them all in general. Through information and communication theoretic an alysis\, RSMA is shown to be optimal (from a Degrees-of-Freedom region per spective) in a number of scenarios and provides significant room for spect ral efficiency\, energy efficiency\, fairness\, reliability\, QoS enhancem ents in a wide range of network loads and user deployments\, robustness ag ainst imperfect Channel State Information at the Transmitter (CSIT)\, as w ell as feedback overhead and complexity reduction over conventional strate gies used in 5G. The benefits of RSMA have been demonstrated in a wide ran ge of scenarios (MU-MIMO\, massive MIMO\, multi-cell MIMO/CoMP\, overloade d systems\, NOMA\, multigroup multicasting\, mmwave communications\, commu nications in the presence of RF impairments and superimposed unicast and m ulticast transmission\, relay\,…) and systems (terrestrial\, cellular\, satellite\, …). Thanks to its versatility\, RSMA has the potential to ta ckle challenges of modern communication systems and is a gold mine of rese arch problems for academia and industry\, spanning fundamental limits\, op timization\, PHY and MAC layers\, and standardization.
