Multiple access is one of the core technologies in wireless communications, which enables wireless base stations to support a large number of terminal users and serve them simultaneously under stringent spectrum constraints. Orthogonal multiple access (OMA), as one multiple access method, has been prevailing since the first generation (1G) cellular system. However, the number of active users allowed access to the OMA system is strictly limited by the number of available orthogonal resources since as required by OMA the communication resources allocated to different users are orthogonal in at least one radio resource dimension, e.g., frequency, time, code, etc. Nowadays, with the rapid growth of mobile network and Internet of Things (IoT) this problem becomes more and more critical. 

Non-orthogonal multiple access (NOMA), as another multiple access method, arises as a promising solution to the aforementioned problem. In contrast to OMA, NOMA simultaneously accommodates a multitude of users with the same radio resource via superposition coding and successive interference cancellation (SIC), achieving high spectral efficiency, massive connectivity, and enhanced user fairness. Owing to its promising features, NOMA has been highlighted in many fifth generation (5G) white papers produced by industrial and academic bodies. However, there are still a number of open issues remaining to be solved before NOMA can be successfully applied in practical systems. 

This feature topic aims to bring together leading researchers in both academia and industry from diversified backgrounds to unlock the potential of NOMA for beyond 5G networks. Extended versions of papers published in conferences, symposiums, or workshop proceedings are encouraged for considerations.

This feature topic “New advances in non-orthogonal multiple access” invites submissions of high-quality original research papers capturing the state-of-the-art advances in NOMA and foster new avenues for research in this area. Potential topics of interest include, but not limited to areas listed above.

Papers should be submitted in two separate .doc files (preferred) or .pdf files: 1) Main Document (including paper title, abstract, key words, and full text); 2) Title page (including paper title, author affiliation, acknowledgement and any other information related with the authors’ identification) through the Manuscript Central. Please register or login at http://mc03.manuscriptcentral.com/chinacomm, then go to the author center and follow the instructions there. Remember to select “New advances in Non-Orthogonal Multiple Access–November Issue, 2020” as your manuscript type when submitting; otherwise, it might be considered as a regular paper.

Each submission must be accompanied by the following information:
