W03-S1 NOMA5G: Keynote Session #1

Keynote 1: Uplink NOMA Transceivers and Procedures in 3GPP
Dr. Yan Chen (Huawei, China)

Abstract To address the massive connectivity requirement from the future IoT networks, NOMA technologies together with different transmission modes have been comprehensively discussed in the 3GPP RAN1 working group for almost three years. A dozen of NOMA transmit schemes and various receivers have been proposed targeting to enhance the connectivity capability while keeping the receiver at reasonable complexity. Moreover, when applied in grant-free transmission for sporadic traffics, the transmission procedures involving both UE activity detection and multi-user decoding has also been warmly discussed too. This talk will give an introduction to the long story of NOMA in 3GPP, together with a technical digest of all the schemes proposed. Last but not least, the future directions and challenges to work on.

Keynote 2: Perspectives on Standardization and Research on NOMA
Dr. Afshin Haghighat (InterDigital, Canada)

Abstract: Multi-User Superposition Transmission (MUST) that was studied for the downlink of 4G LTE Rel-13 is considered the first Non-Orthogonal Multiple Access (NOMA) scheme intended for a cellular system. In 5G NR, NOMA transmission techniques have been considered and studied for uplink operations. In an uplink NOMA scenario, multiple user equipments (UEs) attempt to consume the same time/frequency resources available in the system. In NR, there are three main use cases considered for uplink NOMA, namely, massive machine to machine communication (mMTC), ultra reliable low latency communication (URLLC) and enhanced mobile broadband (eMBB) where each use case calls for its unique operational requirements. While NOMA detection and demodulation requires a more complex processing and treatment of the received signal, it is expected that a NOMA-based transmission could yield a better spectrum usage as well as higher flexibility of operation. This talk will provide a summary of the state and activities related to 3GPP NR NOMA standardization. Furthermore, it will also cover some of the ongoing research related to NOMA such as spreading sequence design, receiver complexity aspects, emerging use cases and applications of NOMA.

Bio: Afshin Haghighat is a Principal Engineer at InterDigital where he has been involved in advanced research and standardization of 5G NR and 4G LTE cellular systems. During the 5G NR Rel-15/16 NOMA studies, he led InterDigital NOMA-related research and 3GPP standardization activities. Prior to InterDigital, he worked at Harris Corporation (1998 – 2005) where he contributed and led the development of advanced software-defined modems for high data rate backhaul point-to-point microwave systems. Before joining Harris, he worked at SR Telecom (1997 – 1998) where he was responsible for design and implementation of various microwave integrated transceiver platforms for point-to-multipoint radios. His main areas of interest and expertise are RF Systems, Communications and Signal Processing. He received a Ph.D. in Electrical Engineering from Concordia University and an MBA from McGill University.

W03-S4 NOMA5G: Keynote Session #2

Keynote 3: Non-orthogonal Multiple Access for 5G and Beyond Wireless Networks

Prof. Octavia A. Dobre (Memorial University, Canada)

Abstract:

With the 3GPP Release 15 on the 5G New Radio out in 2018 and with Release 16 coming out this year, 5G is already a reality. While continuing to address the ever increasing demand for high data rates, ubiquitous connectivity and mobility provisioning, 5G and beyond wireless also aims to accommodate a massive number of devices with various traffic characteristics. Massive connectivity and ultra-reliable low-latency communications represent new features, which bring up major changes in the wireless ecosystem. In recent years, innovative technologies, e.g., non-orthogonal multiple access (NOMA),  have been explored to satisfy the wide requirements in terms of capacity per area, peak and user experienced data rate, spectral and energy efficiency, mobility, connection density, and latency. This talk focuses on the role of NOMA in fulfilling the requirements of 5G and beyond wireless networks. The existing efforts, as well as the advantages and challenges of adopting NOMA in the new generation wireless networks,  will be underlined. Finally, open research questions will be highlighted.
