The Fifth International Workshop on Next Generation Multiple Access (NGMA) for Future Wireless Communications

Multiple access has long been the “pearls in the crown” for each generation of mobile communication networks. In the past generations, grant-based orthogonal multiple access (OMA) schemes such as Time Division Multiple Access, Frequency Division Multiple Access, Code Division Multiple Access, and Orthogonal Frequency Division Multiple Access, have been the major schemes, where each user is allocated with one orthogonal time/frequency/code resource. Now, we colleague already stand at 5G “Square” and heading towards 6G. The evolution from 5G towards 6G is expected to transfer the communication philosophy from connected people and things to connected intelligence, which brings new usage scenarios and new challenges for conventional OMA-based systems. In addition to the explosive data demand in 6G, emerging bandwidth thirsty applications (e.g., virtual reality, augmented reality), massive connectivity (e.g., Internet-of-Things networks connecting billions of machine-type devices), ubiquitous wireless coverage (e.g., space-air-ground-integrated-networks), multi-functional wireless networks (e.g., the integrations of communication, sensing, and computation), and bit-beyond transmissions (e.g., semantics/tasks/goals-oriented communications) create new challenges for multiple access. Given the limited radio resources and the stringent rate/latency/connectivity requirements, it necessitates the paradigm shift in multiple access design from grant-based OMA to non-orthogonal/massive/random/grant-free multiple access and other possible multiple access for 6G, namely Next Generation Multiple Access (NGMA). Moreover, the development of NGMA has also to be jointly considered with new enabling technologies, new spectrums, advanced artificial intelligence tools/native intelligence, etc. This workshop aims to attract novel and solid contributions on the emerging topic of NGMA for future wireless communications.
