Workshop 1

Title: Next-Generation Multiple Access for 6G

Summary: Due to the limited spectrum resource, multiple access design is one of the most challenging problems for each generation of wireless networks. Among the multiple access families, next generation multiple access (NGMA) is a promising technique since it accommodates multiple users over the same resource block, thus enhancing the connectivity and spectrum efficiency. Recall the fact that the communication requirements in 6G are stringent, it force the current Non-orthogonal multiple access (NOMA) to evolve into the next generation with the aid of new techniques. 

This workshop focuses on attracting novel and solid contributions on the emerging topic of NGMA for 6G. Both theoretical and more applied contributions are solicited, covering, but not necessarily limited to, the following topics: 
  • Fundamental limits and performance analysis of NGMA
  • Advanced channel coding and modulation for NGMA 
  • NGMA for ultra-reliable low-latency communication (URLLC)
  • NGMA enhanced multi-function communications, e.g., ISAC and Integrated Navigation and Communication 
  • Machine learning and big data aided NGMA 
  • Multiple antenna-assisted NGMA 
  • Reconfigurable intelligent surfaces (RIS)/Simultaneously transmitting and reflecting (STAR) RIS aided NGMA 
  • NGMA enabled mobile edge computing 
  • NGMA aided aerial communications 
  • NGMA for emerging technologies, e.g., THz, CoMP, OTFS, VLC
