The 5G air interface is targeted to have higher transmission rates, faster access, support of larger user density, and better user experience for enhanced mobile broadband (eMBB) services. Meanwhile, it connects to new vertical industries and new devices, creating new application scenarios such as massive machine-type communications (mMTC) and ultra-reliable and low-latency communications (URLLC) services by supporting massive number of devices and enabling mission critical transmissions with ultra-high reliability and ultra-low latency requirement, respectively. In the study towards 5G air interface standardization, non-orthogonal multiple access (NoMA) is one of the most popular topics with 15 different schemes proposed already. Generally, NoMA can efficiently support higher capacity with greater flexibility and robustness, as well as adaptability towards large number of connections. These properties contribute towards a better user experience for variant kinds of services.

This workshop aims to provide a platform for the leading researchers in this area, both from academia and industry, to share their views and the most recent ideas, progress in algorithm and procedure design, as well as prototype implementation in lab or field on NoMA related techniques for 5G radio access networks. The workshop also aims to stimulate enthusiastic discussions among all experts on how the NoMA can best fit in the whole system design and help to meet the diverse requirements of 5G radio networks for eMBB, mMTC, as well as URLLC services.

Topics of interest include but are not limited to the following:

  • Transmitter side signal processing design for NoMA, i.e., the best configuration of the following components
    • Advanced channel coding and modulation, new constellation mapping, etc.
    • Symbol level processing, including different kinds of spreading, repetition, interleaving, new constellation mapping, etc.
    • Coded bit level processing, including interleaving, scrambling, etc.
    • Symbols to resource elements mapping, sparse or not, etc.
  • Advanced multi-user receiver for performance enhancement and complexity reduction
  • Signal processing and procedures for NoMA based uplink grant-free data transmissions
    • Blind UE detection
    • HARQ, link adaptation, power control, and resource optimization
    • Tailored design for eMBB, mMTC, URLLC services and potential multiplexing
  • Joint design and optimization of NoMA scheme with other air interface technologies
    • Uplink and downlink (massive) MIMO with NoMA
    • Closed-loop and open-loop CoMP with NoMA
    • Flexible duplex/full duplex with NoMA
    • UE/relay cooperation with NoMA
    • Device-to-device communications with NoMA
  • Link/system level performance evaluation and comparison of different NoMA schemes
  • Prototype verification and/or field trial of NoMA scheme implementations
