6G Wireless Channel Measurements and Models: Trends and Challenges

Dear Colleagues,

Fifth generation (5G) wireless communication networks were deployed worldwide in 2020 and more capabilities are in the process of being standardized, such as mass connectivity, ultra-reliability, and ultra-low latency. However, 5G will not meet all requirements of the future in 2030 and beyond, therefore, research into sixth generation (6G) wireless communication networks has been launched to meet all of the requirements of the future network. The knowledge of the propagation channel has historically been an essential element for the flexible and practical system design, optimization, and deployment of communication systems. In the same context, a fundamental understanding of the propagation mechanisms encountered in future 6G wireless communication channels is therefore crucial for the success of future 6G services.

The purpose of this Special Issue is to bring together researchers and practitioners from many fields to report recent research emerging/developing trends and challenges in 6G wireless channel measurements and models. The topics of interest include, but are not necessarily limited to the following:

• Channel measurements and modeling for millimeter-wave, terahertz, optical and satellite communications;
• Analytical, geometric, statistical or deterministic approaches to modeling time-varying channels;
• Measurements and modeling of channel dispersion in time, frequency and angle domains;
• Massive MIMO channel measurements and models;
• Parameters and transmission characteristics of propagation models and measurements
• Channel parameters estimation methods;
• Channel sounder configuration and measurement techniques;
• Channel measurements and modeling for various environments.

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. Future Internet is an international peer-reviewed open access monthly 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 1800 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.
