Multiple Access for 5G – A New Look on NOMA
Nanjing University of Posts and Telecommunications
Abstract: Multiple access refers to the way radio resources are shared among different users. The multiple access techniques used in 2G and 3G cellular networks were time-division multiple access (TDMA) and code-division multiple access (CDMA), both being used in conjunction with single-carrier transmission. A big leap came out when WiFi and 4G cellular standards were developed. All of these networks adopted orthogonal frequency-division multiplexing (OFDM) for transmission, but they differed in the way the radio resources were shared. While WiFi continued to use conventional TDMA, WiMAX used orthogonal frequency-division multiple access (OFDMA), and 3GPP LTE used OFDMA on the downlink and single-carrier frequency-division multiple access (SC-FDMA) on the uplink. For the development of future 5G networks, the 3GPP has already adopted OFDMA for Enhanced Mobile Broadband (eMBB) and Ultra Reliable Low Latency Communications (URLLC) traffics, but non-orthogonal multiple access (NOMA) still stands as a strong candidate for Massive Machine-Type Communications (mMTC). The basic principle of NOMA is to superpose user signals and employ serial interference cancellation (SIC) at the receiver. In this talk, we review current work on NOMA, discuss its potential and the related challenges, and present a new approach which relaxes the power imbalance constraint for the superposed signals and opens up new directions.

High-Spectral Efficiency Communications: Fundamentals to Advanced Technologies for 5G and Beyond
Over the last four decades, mobile communications has continued to grow at a marvelous rate from the 1st generation (1G) to the 4th generation (4G) with significant contributions and impacts to the global economy development. The next mobile communications generations (5G & beyond) will facilitate the development of countries toward a smart society model based on internet-of-things (IoT) infrastrutures. In many developed countries, universities and enterprises have been establishing productive research collaborations to develop 5G technologies for their commercialization by 2020. In Vietnam, research collaborations between universities and enterprises in the area of mobile communications are still limited.
To develop productive research collaboration networks of universities and enterprises in communications industry, the University of Danang invited internationally prestigious experts to conduct (i) training workshops on advanced technologies of future mobile communications and (ii) the development of advanced techniques for next mobile communications generations. In May 2018, the University of Danang and invited prestigious experts organize a training workshop with the following agenda.

Abstract: Enabling wireless transceivers to operate in full-duplex (FD) fashion, by simultaneously transmitting and receiving over the same frequency band, offers the potential to double their transmission rate or spectral efficiency, as compared to currently used half-duplex (HD) transmission mode. When simultaneously transmitting and receiving, the transceiver experiences co-channel interference from its own transmitter, known as self-interference (SI). This SI is usually several orders of magnitude higher than the intended signal, transmitted by the other transceiver, as the later signal crosses longer distance than the SI. Given that the transmitted SI is known, one may directly use it to remove the SI from the received signal. However, the propagation channel and the transmitter (Tx) and receiver (Rx) impairments affect the received SI making it different from the known transmitted signal. A good self-interference (SI) cancellation strategy in full-duplex (FD) communication passes first by a proper understanding of the nature of this SI. The SI can be gradually reduced by a combination of radio-frequency (RF) and baseband cancellation stages. Each stage requires the estimation of the different distortions that the SI endures such as the SI channel and the transceiver nonlinearities.
This talk will start with the SI-channel characteristics, and then continue with the various SI-cancellation aspects: strategies, limiting factors, and techniques, and end with potential FD applications.
