Special Issue on Advanced Technologies for Multi-access Edge Computing
Submission Date: 2020-09-20

With the exponential growth of data traffic due to ubiquitous portable devices, machine to machine communications, and novel user-centric applications, such as augmented/virtual reality, the demands for a new computing paradigm are increasing. The large pool of traditional cloud resources and services has contributed to the development of cloud computing. However, state-of-the-art cloud computing turns into a problem for communication-intensive applications, which need to meet the stringent delay requirements. The problem becomes more severe with the introduction of new data-intensive applications in the Internet of Things era. Multi-access Edge Computing which processes data at the nearest available nodes is emerging as a promising computation architecture to handle these ever-increasing demands. It aims to enable flexible and rapid deployment of new applications and services for customers at the cellular base stations or other edge nodes. It allows cellular operators to open their radio access network to authorized third parties, and moves the computing of traffic and services to the edge of the network to achieve low latency. However, there are several challenges that need to be addressed before we can enjoy the benefits of the advanced Multi-access Edge Computing architecture. For example, these problems include the heterogeneity of different kinds of devices, the deployment of services and applications, and the task allocation and offloading, as well as resource management. This Special Issue will bring together leading researchers and developers to explore recent advanced technologies for Multi-access Edge Computing, especially in the wireless personal communications field, in terms of system, service and application. Relevant topics of interest to this special section include (but are not limited to): Advanced communication network planning and operation in Multi-access Edge Computing Autonomous mobile edge system in wireless personal communication Operating system and framework for Multi-access Edge Computing Smart mobile edge services and application Testbed, experiments, and simulations of advanced mobile edge system Advanced workload allocation and offloading mechanisms Green and sustainable resource management Advanced QoS adaptive design and algorithms in Multi-access Edge Computing Performance optimization in Multi-access Edge Computing Artificial intelligence algorithm design and application in Multi-access Edge Computing Advanced security and privacy in Multi-access Edge Computing Tools and benchmarks for intelligent Multi-access Edge Computing system

Special Issue on Artificial Intelligence for Physical Layer Wireless Communications
Submission Date: 2020-09-30

Artificial Intelligence (AI) approaches including Deep Learning (DL), deep reinforcement learning (DRL), transfer learning (TL), federated learning (FL), distributed learning, well known from computer science disciplines, are beginning to emerge in the wireless communications. These AI approaches have been first widely applied to the upper layers of wireless communication systems for various purposes, such as network traffic prediction and routing optimization. These system models and algorithms designed with AI technology greatly improve the performance of communication systems based on traditional methods. Due to the new features of future communications, such as complex scenarios with unknown channel models, high speed and accurate processing requirements, high computational burden, complicate heterogeneous networks, traditional methods are no longer suitable which brings much more potential application of AI. Just as intelligent technology has become a new hotspot in the research of physical layer wireless communications and challenges conventional communication theories. Currently DL-based ‘black-box’ methods show promising performance improvements but have certain limitations, such as lack of solid analytical tools and use of architectures that are specifically designed for communication and implementation research. With the development of DL technology, in addition to the traditional neural network-based data-driven model, the model-driven deep network model and the DRL model which combined DL with reinforcement learning are more suitable for dealing with future complex communication systems. Such as in most cases of wireless resource allocation, there are no definite samples to train the model, hence DRL which trains the model by maximizing the reward associated with different actions can be adopted. Hence, the goal of this Special Issue is to disseminate the latest research and innovations on Artificial Intelligence for Physical Layer Wireless Communications. Review papers on this topic are also welcome. Potential topics include, but are not limited to: Fundamental trends and challenges for AI empowered physical layer B5G/6G AI for physical B5G and 6G AI based channel modeling AI based multiuser detection AI based modulation and coding AI for millimeter wave technologies AI based direction-od-arrive estimation AI based modulation signal classification AI based ultra-dense cell communication AI for physical layer heterogeneous networks AI based testbeds and experimental evaluations AI based beamforming in mmWave massive MIMO AI based unmanned aerial vehicles (UAVs) techniques AI based non-orthogonal multiple access (NOMA) techniques Other emerging AI based physical communications technologies AI based hybrid precoding in massive MIMO system, mmWave system

Special Issue on Advanced Signal Processing (ASP) and Its Applications in B5G Wireless Communication Networks
Submission Date: 2020-10-30

The fifth generation (5G) wireless communication networks are actively being developed and will be rolled out around 2020, after which we are going to enter the beyond 5G (B5G) wireless communications era. With respect to the development law of wireless communication traffic "1000 times in 10 years", B5G wireless communication networks should achieve greater system capacity (> 1000 times) in terms of data rate (terabits per second) and user density (the internet of things). Yet, they are also expected to provide lower latency, high reliability, better security and more intelligence, etc.. To achieve these requirements, we cannot only rely on a simple technology; in fact, we need to integrate multiple key technologies that include extreme densification of infrastructure, large quantities of new bandwidth, and a larger number of antennas, etc., just tp mention a few. This renders traditional signal processing and methods not applicable for B5G communication networks. Therefore, there is great immediacy to develop advanced signal processing techniques, methods and algorithms to characterize the performance of B5G networks. Moreover, faced with the coming B5G era, the intelligence applications, such as autonomous driving, smart cities and telehealth, that require lower latency and high reliability should be also fully explored, The objective of this special issue is to solicit relevant contributions from both academia and industry, to motivate discussions on advanced signal processing theories and methods for B5G wireless communication networks, which span array signal processing, wireless signal transmission, information processing, practical applications and realistic scenarios, etc.. Both theoretical contributions and application validations are welcomed. Potential topics include but are not limited to: l New architectures for B5G communication with ASP l New waveforms and coding for B5G communication with ASP l Intelligence applications to B5G communication with ASP l Resource allocation and management schemes for B5G communication with ASP l Mobile edge computing for B5G communication with ASP l Cloud computing and big data for B5G communication with ASP l Higher frequency band (millimeter wave, and terahertz) operation for B5G communication with ASP l Satellite, unmanned aerial vehicle (UAV), and ocean communications for B5G communication with ASP l Smart antenna and array antenna design for B5G communication with ASP l Data reliability, privacy and security for B5G communication with ASP l Network infrastructure, backhaul & core network issues for B5G communication with ASP l Vehicle to vehicle (V2V) communications for B5G communication with ASP l Energy harvesting, storage, and recycling for B5G communication with ASP l New applications and scenarios of B5G communication with ASP l Other emerging techniques for B5G communication with ASP
