“…In [67], Orbital Angular Momentum (OAM) based multiplexing is discussed as one of the potential key technology for the 6G network OAM based access technique is advantageous for fulfilling the required demand of high spectral efficiency and high capacity with enhanced reliability. In [85], a Rank based access technique is used for providing access to the user based on mobility. Pedestrian users are assigned as Rank I, mobile users with a medium speed of less than 30 Km/h are assigned as Rank II and the high-speed mobile users are assigned with Rank III.…”

Nowadays, 5G is in its initial phase of commercialization. The 5G network will revolutionize the existing wireless network with its enhanced capabilities and novel features. 5G New Radio (5G NR), referred to as the global standardization of 5G, is presently under the 3 rd Generation Partnership Project (3GPP) and can be operable over the wide range of frequency bands from less than 6GHz to mmWave (100GHz). 3GPP mainly focuses on the three major use cases of 5G NR that are comprised of Ultra-Reliable and Low Latency Communication (uRLLC), Massive Machine Type Communication (mMTC), Enhanced Mobile Broadband (eMBB). For meeting the targets of 5G NR, multiple features like scalable numerology, flexible spectrum, forward compatibility, and ultra-lean design are added as compared to the LTE systems. This paper presents a brief overview of the added features and key performance indicators of 5G NR. The issues related to the adaptation of higher modulation schemes and inter-RAT handover synchronization are well addressed in this paper. With the consideration of these challenges, a next-generation wireless communication architecture is proposed. The architecture acts as the platform for migration towards beyond 5G/6G networks. Along with this, various technologies and applications of 6G networks are also overviewed in this paper. 6G network will incorporate Artificial intelligence (AI) based services, edge computing, quantum computing, optical wireless communication, hybrid access, and tactile services. For enabling these diverse services, a virtualized network slicing based architecture of 6G is proposed. Various ongoing projects on 6G and its technologies are also listed in this paper.

“…The secrecy in simultaneous wireless information and power transferring (SWIPT) in downlink NOMA systems was investigated in [151]. Later, the security challenges of vehicular users in an ultra-dense network were studied in [152]. Here, it was demonstrated that NOMA-based multiple access is successful in attaining a high SSR for vehicular users by efficiently designing the allocation resources.…”

Physical layer security is a promising approach that can benefit traditional encryption methods. The idea of physical layer security is to take advantage of the propagation medium's features and impairments to ensure secure communication in the physical layer. This work introduces a comprehensive review of the main information-theoretic metrics used to measure the secrecy performance in physical layer security. Furthermore, a theoretical framework related to the most commonly used physical layer security techniques to improve secrecy performance is provided. Finally, our work surveys physical layer security research over several enabling 5G technologies, such as massive multiple-input multiple-output, millimeter-wave communications, heterogeneous networks, non-orthogonal

“…Not like PLS in VLC systems only focusing on downlink wireless communication, PLS in NOMA systems can also be applicable to uplink communication [31]. Moreover, PLS in NOMA applied to various systems such as mobile edge computing networks [31], UAV-assisted communication [32,33], and ultra-dense networks [34] has gained much interest from researchers. However, these works on PLS in NOMA systems are all confined to the RF communication field and cannot be directly applied to the VLC field due to the particular characteristics of the optical transceiver and the optical wireless transmission channel.…”
