In this survey paper, we first provide insights on the evolution of radio access networks (RANs) through investigating the existing paradigms and future trends towards 6G. We then present the fully-decoupled RAN (FD-RAN), which aligns with the trends by integrating existing paradigms and introducing new features such as physical decoupling of uplink and downlink base stations. We also discuss the key technologies enabled by different architectures for further performance improvement and some open issues. We hope that this survey can stimulate more in-depth research on transforming 6G RAN so as to unleash the power of state-of-the-art technologies and meet higher performance requirements in the future.
在本调查报告中，我们首先通过研究现有范例和 6G 的未来趋势，深入探讨了无线接入网（RAN）的演进。然后，我们介绍了完全解耦 RAN（FD-RAN），它通过整合现有范例和引入新功能（如上行链路和下行链路基站的物理解耦）来适应发展趋势。我们还讨论了不同架构为进一步提高性能而采用的关键技术以及一些开放性问题。我们希望这份调查报告能促进对 6G RAN 变革的更深入研究，从而释放最先进技术的力量，满足未来更高的性能需求。

The growing interest in the Metaverse has generated momentum for members of academia and industry to innovate toward realizing the Metaverse world. The Metaverse is a unique, continuous, and shared virtual world where humans embody a digital form within an online platform. Through a digital avatar, Metaverse users should have a perceptual presence within the environment and can interact and control the virtual world around them. Thus, a human-centric design is a crucial element of the Metaverse. The human users are not only the central entity but also the source of multi-sensory data that can be used to enrich the Metaverse ecosystem. In this survey, we study the potential applications of Brain-Computer Interface (BCI) technologies that can enhance the experience of Metaverse users. By directly communicating with the human brain, the most complex organ in the human body, BCI technologies hold the potential for the most intuitive human-machine system operating at the speed of thought. BCI technologies can enable various innovative applications for the Metaverse through this neural pathway, such as user cognitive state monitoring, digital avatar control, virtual interactions, and imagined speech communications. This survey first outlines the fundamental background of the Metaverse and BCI technologies. We then discuss the current challenges of the Metaverse that can potentially be addressed by BCI, such as motion sickness when users experience virtual environments or the negative emotional states of users in immersive virtual applications. After that, we propose and discuss a new research direction called Human Digital Twin, in which digital twins can create an intelligent and interactable avatar from the user’s brain signals. We also present the challenges and potential solutions in synchronizing and communicating between virtual and physical entities in the Metaverse. Finally, we highlight the challenges, open issues, and future research directions for BCI-enabled Metaverse systems.

Autonomous vehicles and Intelligent Transport Systems (ITS) have started to become a reality in recent years. However, shortcomings of these early intelligent vehicles demonstrate a need to increase an intelligent vehicle’s perceptual bubble beyond the vehicle’s onboard sensors. Vehicle-to-Everything (V2X) communications is a technology intended to enable intelligent vehicles to increase their perceptive range via communication with the outside world, i.e., other vehicles, road users, and infrastructure. One of the critical layers of V2X communications is that of the underlying wireless access. There remains an open debate on which technology (or technologies) will ultimately be adopted as the de facto wireless access technology for V2X communications. Presently, a myriad of unconnected threads of work are being undertaken to this end, resulting in an unclear picture of the current state of wireless access for V2X communications. In this tutorial review, we collate current research on wireless access for V2X communications to showcase recent developments and the challenges facing candidate technologies. To allow the reader to engage with the debate, we present an overview of the field of V2X communications, its history, and standardisation. Following this, we provide an overview of the key candidate wireless access technologies that may enable V2X communications. Through this work, we aim to provide a comprehensive first step into the discipline of wireless access for V2X communications.

The digital transformation within the automotive industry is accelerating towards an era dominated by autonomous vehicles, with vehicle-to-everything (V2X) communications being a fundamental enabler for this advancement. As vehicular networks evolve to meet the complex demands of autonomous driving, traditional communication systems encounter limitations in bandwidth and data transfer rates. Millimeter-wave (mmWave) communication emerges as a pivotal solution, offering the extensive bandwidth required for the high data throughput and low latency essential in modern vehicular communications. However, challenges loom, with beam alignment in mmWave V2X becoming a time-consuming process and the mmWave’s blockage effect impeding consistent and reliable vehicular communication links. Therefore, the development of efficient, real-time, and robust beam alignment technology is crucial for mmWave V2X communication. In this paper, we present a comprehensive survey of beam alignment techniques in mmWave V2X communication. We explore various approaches including beam sweeping, angle of arrival (AoA)/angle of direction (AoD) estimation, black-box optimization, and side information. Subsequently, we introduce performance metrics for assessing beam alignment performance and compare the performance of four beam alignment methods under different metrics. Finally, we summarize the future research directions and challenges faced by beam alignment techniques in mmWave V2X communication, offering valuable insights for researchers in this field.

In this paper, we review the current state-of-the-art of resource allocation for power line communication systems. The study systematically presents the advancements achieved in this field over the past decades. To achieve this, we adopt two complementary perspectives: a power line communication-centric view and an optimization-centric view. The former highlights resource allocation within the eye of the power line communication community, while the latter emphasizes optimization principles, focusing on the technical aspects of resource allocation. Subsequently, we meticulously present the progress made in both single- and multi-user scenarios, employing a chronological approach to provide readers with a coherent narrative of the evolution and important findings. Furthermore, we accentuate critical insights and valuable lessons gathered from these developments. In conclusion, we explore future trends and prospects within the scope of resource allocation for power line communication systems, intending to inspire research initiatives that push the boundaries beyond the existing state-of-the-art.

The effects of transport development on people’s lives are diverse, ranging from economy to tourism, health care, etc. Great progress has been made in this area, which has led to the emergence of the Internet of Vehicles (IoV) concept. The main objective of this concept is to offer a safer and more comfortable travel experience through making available a vast array of applications, by relying on a range of communication technologies including the fifth-generation mobile networks. The proposed applications have personalized Quality of Service (QoS) requirements, which raise new challenging issues for the management and allocation of resources. Currently, this interest has been doubled with the start of the discussion of the sixth-generation mobile networks. In this context, Network Slicing (NS) was presented as one of the key technologies in the 5G architecture to address these challenges. In this article, we try to bring together the effects of NS implications in the Internet of Vehicles field and show the impact on transport development. We begin by reviewing the state of the art of NS in IoV in terms of architecture, types, life cycle, enabling technologies, network parts, and evolution within cellular networks. Then, we discuss the benefits brought by the use of NS in such a dynamic environment, along with the technical challenges. Moreover, we provide a comprehensive review of NS deploying various aspects of Learning Techniques for the Internet of Vehicles. Afterwards, we present Network Slicing utilization in different IoV application scenarios through different domains; terrestrial, aerial, and marine. In addition, we review Vehicle-to-Everything (V2X) datasets as well as existing implementation tools; besides presenting a concise summary of the Network Slicing-related projects that have an impact on IoV. Finally, in order to promote the deployment of Network Slicing in IoV, we provide some directions for future research work. We believe that the survey will be useful for researchers from academia and industry. First, to acquire a holistic vision regarding IoV-based NS realization and identify the challenges hindering it. Second, to understand the progression of IoV powered NS applications in the different fields (terrestrial, aerial, and marine). Finally, to determine the opportunities for using Machine Learning Techniques (MLT), in order to propose their own solutions to foster NS-IoV integration.

Smart cities demand resources for rich immersive sensing, ubiquitous communications, powerful computing, large storage, and high intelligence (SCCSI) to support various kinds of applications, such as public safety, connected and autonomous driving, smart and connected health, and smart living. At the same time, vehicles equipped with significantly powerful SCCSI capabilities are expected to become ubiquitous in future smart cities. By observing the convergence of these two trends, this article advocates the use of vehicles to build a cost-effective service network, where SCCSI-empowered vehicles form a web of mobile sensors, a grid of mobile servers, a network of mobile routers, a fleet of mobile storage, and a set of AI toolboxes, to provide SCCSI services in smart cities. This paradigm is called Vehicle as a Service (VaaS). Towards this goal, this article first examines the potential use cases in smart cities and possible upgrades required for the transition from traditional vehicular ad hoc networks (VANETs) to VaaS. Then, the system architecture and use cases of the VaaS paradigm are comprehensively elaborated. Finally, the open problems of this paradigm and future research directions, including architectural design, service provisioning, incentive design, and security & privacy, are identified. This position paper is expected to pave the way towards developing a cost-effective and sustainable approach for smart cities and offer a complementary alternative for 5G and beyond.
智慧城市需要丰富的沉浸式传感、无处不在的通信、强大的计算、大容量存储和高智能（SCCSI）资源，以支持公共安全、互联和自动驾驶、智能和互联健康以及智慧生活等各类应用。与此同时，配备强大 SCCSI 功能的车辆有望在未来的智慧城市中无处不在。通过观察这两种趋势的融合，本文提倡利用车辆构建一个经济高效的服务网络，在这个网络中，具备 SCCSI 功能的车辆将形成一个移动传感器网络、一个移动服务器网格、一个移动路由器网络、一个移动存储车队和一套人工智能工具箱，为智慧城市提供 SCCSI 服务。这种模式被称为 "车辆即服务"（VaaS）。为实现这一目标，本文首先探讨了智慧城市中的潜在用例，以及从传统车载 ad hoc 网络（VANET）过渡到 VaaS 所需的可能升级。然后，全面阐述了 VaaS 模式的系统架构和使用案例。最后，确定了该范例的开放问题和未来研究方向，包括架构设计、服务提供、激励设计以及安全和隐私。预计本立场文件将为智能城市开发具有成本效益和可持续发展的方法铺平道路，并为 5G 及其他技术提供补充选择。
