New Trends in Next-Generation Wireless Transmissions

Dear Colleagues,

The ITU has released data on 6G usage scenarios and performance metrics. 6G networks will further integrate communication with AI and sensing, enable space–air-ground–sea ubiquitous connectivity, and further enhance 6G’s coverage, sensing- and AI-related capabilities, sustainability, interoperability, and positioning. Many new emerging key technologies have been proposed to achieve this goal, including integrated sensing and communication (ISAC), reconfigurable intelligent surfaces (RISs), holographic multiple-input multiple-output (MIMO), movable antenna (MA)/fluid antenna system (FAS), channel knowledge map (CKM), AI, digital-twins, etc.

Such wireless transmission technologies are related to the transmitting and processing of wireless signals to achieve better performance with limited resources. They are crucial for next-generation communication system design, performance analysis, and optimization.

The aim of this Special Issue is to showcase recent advances and future challenges on 6G wireless transmission research, which fits well within the journal’s scope.

In this Special Issue, original research articles and reviews are welcome for submission. Research areas may include (but are not limited to) the following:

• ISAC waveform design and performance analysis;
• RIS communications;
• Holographic MIMO communications;
• MA/FAS-assited communications;
• CKM-enabled system design;
• AI/digital-twin-enabled communications and sensing;
• Millimeter wave/THz/optical wireless transmission;
• New multiple access schemes.

We look forward to receiving your contributions.

Manuscript Submission Information

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 250 words) can be sent to the Editorial Office for assessment.

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.
