NOMA Techniques in Emerging Wireless Systems

About this Research Topic

Non-orthogonal multiple access (NOMA) has become an important principle for the design of radio access techniques for the fifth generation (5G) wireless networks and beyond. Although several 5G multiple access techniques have been proposed by academia and industry, including power-domain NOMA, sparse code multiple access (SCMA), pattern division multiple access (PDMA), low density spreading (LDS), and lattice partition multiple access (LPMA), these techniques are based on the same key concept, where more than one user is served in each orthogonal resource block, e.g., a time slot, a frequency channel, a spreading code, or an orthogonal spatial degree of freedom. Academic and industrial research has also demonstrated that NOMA can effectively support massive connectivity, which is important to ensure that the forthcoming 5G network can support the Internet of Things (IoT) functionalities.
Compared to conventional OMA techniques, some new challenges and designs are highlighted by the NOMA technique. The basic idea of SIC in the NOMA network is to successively detect the signal with the strongest power and cancel it from the received mixed signal. Resource allocation problems involved in NOMA are also challenging. The NOMA networks face more severe security issues among the legitimate users.

This Research Topic aims to provide a forum for the latest NOMA research, innovations, and applications for next generation wireless networks, in order to bridge the gap between theory and applications. We solicit high-quality original research papers on topics including, but not limited to:
• Fundamental limits and performance analysis of NOMA
• Advanced channel coding and modulation for NOMA
• Resource allocation and mobility management for NOMA
• Grant free and semi-grant free multiple access
• Cooperative NOMA
• Security Provisioning for NOMA
• The Application of Wireless Power Transfer to NOMA
• Massive multiple access schemes for future IoT
• Machine learning and big data aided NOMA
• Reconfigurable intelligent surfaces-assisted NOMA


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
