# Editorial for the Special Issue on Moving Towards 6G Wireless Technologies
###### Abstract
This is considered one of the primary potential components of 6G networks, taking into account the instances of RIS as a Smart Reflector (SR) and an Access Point (AP). According to simulations, their results show that RIS-assisted FNOMA surpasses FNOMA by 62% in terms of outage and sum capacity. The authors in [7] discuss the essential parameters of 6G technology, exploring the substantial challenges that will have to be surmounted to realize the desired benchmarks and fulfill the envisioned potential. Wireless networks based on 6G promise, in fact, to deliver a substantial increase in the Quality of Service (QoS) while also emphasizing sustainability. The authors discuss how this assurance is underpinned by a new architectural paradigm shift around existing and emerging spectrum technologies such as THz, Visible Light Communication (VLC), and molecular and quantum communication. This paradigm also encompasses integrating terrestrial and non-terrestrial networks, fostering intelligent connections made possible by pervasive AI, and bolstering the network's protocol stack framework. In [8], the authors investigate how to solve the problem of the shortage of energy harvested by users in communication systems using the Active RIS (A-RIS)-assisted Simultaneous Wireless Information and Power Transfer (SWIPT) technique. The problem of maximizing the sum of energy harvested by the users has been established under the constraints of the minimum signal-to-dry-noise ratio required by the user, the maximum power of A-RIS, the maximum power of the base station, and the Power Splitting (PS) ratio. The numerical values have demonstrated an efficient convergence of the proposed algorithm. In [9], the authors contribute to the understanding and optimization of VLC systems for IoT, which they consider crucial in the 6G era for their application versatility in various scenarios. Specifically, they highlight the growing efficiency of lighting LEDs in infrastructure, facilitating the seamless integration of VLC. Then, they analyze VLC's robustness in outdoor settings, demonstrating effective communication up to 10 m. Finally, the authors delve into multi-carrier modulation schemes, Orthogonal Frequency-Division Multiplexing (OFDM) and Universal Filtered Multi Carrier (UFMC), exploring the adaptations for UFMC in VLC, revealing a superior performance compared to OFDM. Finally, in [10], the authors investigate the major challenges presented by the demanding needs of Vehicular Ad Hoc Networks (VANETs) in the Beyond 5G (B5G) and 6G eras, including extremely low latency, exceptional reliability, and seamless communications at high mobilities. Their paper introduces a novel structure for VANETs based on fog computing, Mobile Edge Computing (MEC), and a microservices architecture. The authors demonstrate how utilizing this approach can improve the network's capacity to handle computational activities and maintain minimal latency effectively. In conclusion, this Special Issue presents a range of papers that explore the development and evaluation of key 6G-enabling solutions currently addressed in the research community and that can help meet the ambitious goals of upcoming 6G networks.
