“…Moreover, transmit antenna selection (TAS) scheme has been verified as a low complexity solution to improve performance of NOMA systems when multiple antennas are available at the base station [17]- [22]. The authors of [17] and [18] investigated the performance of an energy harvesting AF relaying NOMA system with TAS scheme and closedform expressions for OP was obtained. A new TAS scheme for multiple-input single-output (MISO) NOMA systems was proposed in [19] and their result testified that higher performance can be obtained with multiple antennas at base station.…”

In this paper, we propose an impartial simultaneous wireless information and power transfer (SWIPT)assisted cooperation mechanism for a non-orthogonal multiple access (NOMA) downlink scenario.Specifically, both a cell-center user and a cell-edge user apply the power-splitting technique and utilize the harvested energy to forward the other user's information on the premise of successful decoding of their own information. Both analytical and numerical results show that the proposed impartial user cooperation mechanism (IUCM) outperforms the traditional partial cooperation mechanism in terms of outage probability, diversity order and diversity-multiplexing trade-off (DMT). For comparison, we further incorporate the IUCM into an orthogonal frequency-division multiple access (OFDMA) framework, which is shown to preserve the same diversity order, while has a worse but more flexible DMT performance in comparison with the IUCM in the NOMA framework. Although the IUCM in OFDMA has a worse outage performance, it is proved that it has the same optimal system outage probability with the IUCM in NOMA when the relaying channel between the two users is error-free.

“…A QoS optimization problem, considering a two user MISO-NOMA system given a pair of target interference levels was investigated in [128]. The authors of [129], investigated the performance of transmit antenna selection schemes in a two-user MISO-NOMA cooperative transmission with SWIPT enabled at near users, used hybrid TS and PS SWIPT architectures to power near user decode and forward relaying operation. Future Directions: Most of the research works focused on power-domain NOMA with SWIPT.…”

Initial efforts on Wireless Power Transfer (WPT) have concentrated towards long-distance transmission and high power applications. Nonetheless, the less efficiency of the transmission gained and potential health concerns arising due to high power applications, have caused limitations in their further developments. Due to tremendous energy consumption growth with ever increasing connected devices, alternative wireless information and power transfer techniques have been important not only for theoretical research interests but also for the operational costs saving and the sustainable growth of wireless communications. In this regard, Radio Frequency Energy Harvesting (RF-EH) for a wireless communications system presents a new paradigm that allows wireless nodes to recharge their batteries from the RF signals instead of fixed power grids and the traditional energy sources. In this approach, the RF energy is harvested from ambient electromagnetic sources or from the sources that directionally transmit RF energy for EH purposes. Notable research activities and major advances have occurred over the last decade in this direction. In this direction, this paper provides a comprehensive survey of the state-of-art techniques, based on advances and research challenges presented by Simultaneous Wireless Information and Power Transfer (SWIPT) and WPT assisted technologies. More specifically, in contrast to the existing works, this paper identifies and provides a detailed description of various potential emerging technologies for the fifth generation (5G) communications with SWIPT/WPT. Moreover, we provide some interesting research challenges and recommendations with the objective of stimulating future research in this emerging domain.
