With the evolution of fifth generation (5G) networks and increasing demand of high data rates and higher connectivity, new solutions are being investigated in both academia and industry. Recently the technology that has received considerable attention is non orthogonal multiple access (NOMA), which is considered to be one of the key 5G enabling technologies. NOMA is the new addition to the class of multiple access techniques, in which the user multiplexing is done in the power domain, such that the strong users having better channel conditions transmit with low power and the weak users having worse channels transmit with high power, while sharing the same spectral resources. NOMA increases the spectral efficiency further as compared to orthogonal multiple access (OMA) schemes by allowing different users to use the same spectral resources but with different power levels. The NOMA concept forms a general framework, where recently proposed 5G multiple access schemes, such as power domain NOMA, sparse code multiple access (SCMA), bit division multiplexing, multi-user shared access (MUSA), interleave division multiple access (IDMA), lattice partition multiple access (LPMA), and pattern division multiple access (PDMA) can be regarded as special cases.

This workshop will provide a platform to showcase the latest research and innovations in NOMA technologies as well as their applications, and will bridge the gap between theory and practice in the design of 5G multiple access. The recent advancement in NOMA has boosted the development of a new generation of highly-efficient mobile networks.

This workshop will highlight the recent developments in this evolving area. It will provide a platform for exchanging new ideas and research collaboration. Topic are not limited to the following areas:

Prospective authors are invited to submit original manuscripts on topics including, but not limited to:

• Fundamental limits and performance analysis of NOMA
• Channel coding and modulation for NOMA
