This workshop is dedicated to the theory and applications of general and powerful transmission frameworks based on Rate-Splitting Multiple Access (RSMA). RSMA consists in decoding part of the interference and in treating the remaining part of the interference as noise. This enables RSMA to softly bridge and therefore reconcile the two extreme strategies of fully decode interference and treat interference as noise and provide room for spectral efficiency, energy efficiency and QoS enhancements in a wide range of network loads and user deployments, robustness against imperfect Channel State Information at the Transmitter (CSIT), as well as feedback overhead and complexity reduction.
