5G/B5G/6G Wireless Communication and Its Applications

Dear Colleagues,

As the fabric of wireless communication continually weaves more complex patterns, the ascension from 5G to beyond 5G (B5G) and sixth-generation (6G) paradigms marks a renaissance in digital connectivity. Future applications, such as immersive virtual reality, autonomous systems, and comprehensive sensing networks, necessitate a leap in technology that surpasses the existing 5G standards. The ambition of 6G is to deliver an unparalleled, seamless experience uniting humans and the omnipresent digital ecosystem. The characteristics defining 6G encompass ubiquitous global coverage, marked improvements in spectral and energy efficiency, minimized costs, amplified intelligence, and fortified security.

Transitioning to these robust networks entails the adoption of vanguard enabling technologies. Key among these are air interface and advanced transmission technologies designed to significantly boost energy and spectrum efficiency. Innovations like Terahertz bands, optical wireless communications, novel waveforms, sophisticated channel coding strategies, and refined multi-antenna systems play pivotal roles, collectively forging a path to superior network performance.

Concomitantly, pioneering network architectures are pivotal for actualizing this vision. Such architectures include integrated terrestrial and non-terrestrial networks, advances in network softwarization such as SDN/NFV, dynamic slicing for customized service delivery, service-based frameworks, and breakthroughs in distributed computing, with an intersection of cloud, fog, and edge computing elements.

The disruptive potential of artificial intelligence (AI) in network optimization foreshadows a transformation in 6G development. By embedding AI at the core of technology evolution in 6G, there is a significant opportunity to enhance network operations, boost performance efficiency, and tailor multifaceted services to diverse requirements.

Despite this forward momentum, the theoretical and applied aspects of B5G and 6G are nascent and riddled with challenges that are yet to be fully comprehended and addressed. This burgeoning domain calls for meticulous exploration to not only highlight cutting-edge research and development but to also pave the way for existing and forthcoming obstacle resolution.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
