“…A more typical scenario of cooperative relaying networks, in which the near-user can directly communicates with source while the far-user is reached through a dedicated relay, however, has been investigated in wireless networks [23]- [26]. Besides, recall that the incremental relaying, which allows a relay for cooperation only when the channel quality from source to destination is below a given threshold, achieves a significant enhancement of spectral efficiency [27], [28]. More specifically, a negligible 1-bit feedback was introduced for indicating whether the destination node correctly decode its desired signal, i.e., a 1-bit positive feedback is transmitted by the destination node to the source when the desired signal was decoded correctly; otherwise, a 1-bit negative feedback was transmitted.…”

This paper proposes an adaptive cooperative non-orthogonal multiple access (NOMA) scheme for power line communication (PLC) networks, in which the source superimposes the data symbols to two users. Specifically, the source communicates with the far-user with the assistance of relay. Meanwhile, depending on negligible 1-bit feedback, the near-user is reached through an adaptive way which switches between a direct and a cooperative data transmission mode, resulting in an enhancement of the system throughput and a more reliable data reception at the near-user. For this setting, we then analyze the system throughput over the log-normal distributed channel fading with the impulsive noise and investigate the impact of key system parameters. The simulation results validate the theoretical analysis and show that our scheme can obtain a better throughput performance with lower power consumption and reduce the electromagnetic compatibility (EMC) issues for PLC networks more efficiently than the time division multiple access (TDMA) and traditional cooperative NOMA (TCN) schemes. INDEX TERMS Power line communication (PLC), non-orthogonal multiple access (NOMA), log-normal distribution, impulsive noise, system throughput.

“…For fixed relaying, resources between source and relay are allocated in a deterministic way. In adaptive relaying, relays become active only when they require processing information; otherwise they remain silent [70]. Data processing can be done according to the available protocols at the relay.…”

Wireless Power Transfer (WPT) is an innovative technology employed for enhancing the energy sustainability of wireless devices with a limited life span. The idea of integrating WPT in wireless communication leads to the idea of Simultaneous Wireless Information and Power Transfer (SWIPT) that transfers information and power to wireless devices simultaneously, thereby resulting in a drastic increase in spectral efficiency of the network. SWIPT aided Cooperative Relaying (CoR) has emerged as a new trend for Fifth Generation (5G) and Beyond 5G (B5G) systems owing to the rapidly increasing challenges faced by these networks. Cooperative relaying combined with SWIPT can be helpful in overcoming the rising demands of next generation wireless networks by providing an enhanced date rate, low latency, shorter coverage, wide spread connectivity of massive number of devices along with energy-efficiency. This article provides a comprehensive review of SWIPT technology that enables the use of CoR networks for 5G and B5G mobile networks including the significance, technologies, and protocols which can be applied. This article also examines the deployment of cooperative SWIPT involving a single relay, multiple relays and optimal relay selection, multi antenna systems and optimal beamforming .SWIPT under the influence of Hardware Impairments (HI), imperfect Channel State Information (CSI), non-linear energy harvesting models, Intelligent Reconfigurable Surface (IRS), massive MIMO, massive access for the Internet of Things (IoT) has been discussed in detail. Meanwhile, this study discusses key challenges being faced in the implementation of SWIPT for future wireless networks that need to be addressed efficiently.

“…Moreover, it does not emphasize the error of the message and the link quality. While in adaptive relaying, the relays are only active while they need to relay information, otherwise, they remain silent or inactive and hence leading to SE and reliability, but it needs more computational power, creating some delays [44]. Descriptions of various types of relaying mechanisms are given below:…”

The integration of simultaneous wireless information and power transfer (SWIPT) and cooperative relay (CoR) techniques has evolved as a new phenomenon for the next-generation wireless communication system. CoR is used to get energy and spectral efficient network and to solve the issues of fading, path loss, shadowing, and smaller coverage area. Relay nodes are battery-constrained or battery-less devices. They need some charging systems externally as replacing or recharging of their batteries sometimes which are not feasible and convenient. Energy harvesting (EH) is the most cost-effective, suitable, and safer solutions to power up these relays. Among various types of the EH, SWIPT is the most prominent technique as it provides spectral efficiency by delivering energy and information to the relays at the same time. This paper reviews the combination of CoR and SWIPT. From basic to advanced architectures, applications and taxonomies of CoR and SWIPT are presented, various forms of resource allocation and relay selection algorithms are covered. The usage of CoR and SWIPT in the fifth-generation wireless networks is discussed. This paper focuses on the integral aspects of the CoR and SWIPT to other next-generation wireless communication systems and techniques such as multiple-input-multiple-output, wireless sensor network, cognitive radio, vehicular ad hoc network, non-orthogonal multiple access, beamforming technique, and the Internet of Things. Some open issues and future directions and challenges are given in this paper.
