Multiple Access Technologies for 6G Communication Networks
Submit via easychair and select Special Session 1
Non-orthogonal multiple access (NOMA), as a typical multiple access technology in the 5G area, has been widely researched due to its ability to achieve higher spectral efficiency than traditional orthogonal multiple access (OMA). With the commercialization of 5G communication networks, both academia and industry are actively promoting the research and strategic layout of 6G. 6G aims to achieve unprecedented leaps in connectivity performance and reliability improvement, which means that more reliable multiple access technologies are needed to achieve higher efficiency and massive connectivity capabilities. In recent years, a series of novel multiple access technologies represented by rate-splitting multiple access (RSMA) are proposed on the basis of traditional NOMA, which can not only achieve higher spectral efficiency and robustness, but also collaborate with the other frontier technologies such as massive MIMO (mMIMO) and reconfigurable intelligent surface (RIS) for the research on resource optimization and physical layer security (PLS), etc.
