WS-02: Workshop on Rate-Splitting and Next Generation Multiple Access

IEEE WCNC 2022 Workshop on Rate-Splitting and Next Generation Multiple Access



The IEEE WCNC 2022 Workshop on Rate-Splitting and Next Generation Multiple Access will be held in Austin, USA in conjunction with IEEE WCNC 2022.


Rate-Splitting Multiple Access (RSMA) based on Rate-Splitting (RS) is recognized as a more general and powerful transmission framework for the design and optimization of non-orthogonal transmission, multiple access, and interference management strategies. By splitting user messages into common and private parts at the transmitter, and partially decoding interference and treating remaining part of the interference as noise, RSMA enables to softly bridge and therefore reconcile the two extreme interference management strategies of treating interference as noise (as commonly used in 4G/5G, multi-user MIMO, coordinated multipoint-CoMP, massive MIMO, millimetre wave MIMO) and fully decoding interference (as in non-orthogonal multiple access-NOMA). Therefore, RSMA provides room for spectral efficiency, energy efficiency and Quality-of-Service (QoS) enhancements, robustness to imperfect channel state information at the transmitter (CSIT), and feedback overhead and complexity reduction. Next Generation Multiple Access (NGMA) is envisioned to efficiently cope with the high throughput, heterogeneity of QoS, ultra-reliability, low latency, and massive connectivity requirements of future multi-antenna wireless networks. The capabilities of decreasing latency, improving throughput, and enhancing robustness under user mobility and latency in the network make RSMA an excellent candidate for NGMA. This workshop is dedicated to the theory, design, optimization and applications of RSMA and any other potential multiple access techniques in many different scenarios relevant to wireless communication and signal processing for 6G. The workshop will give the audience a comprehensive introduction of the state-of-the-art development in RS and NGMA in the wireless communication and signal processing society. Topics of interest include, but are not limited to:

  • Rate-Splitting Multiple Access to generalize SDMA and NOMA
  • RS/NGMA to achieve the fundamental limits of wireless networks
  • RS/NGMA for multi-user/multi-cell multi-antenna networks
