Special Issue Information
Dear Colleagues,
As 6G approaches, MIMO technology is advancing toward the realization of ubiquitous coverage, ultra-high capacity, and intelligent adaptability. This Special Issue focuses on advanced MIMO technologies from three innovative perspectives: network architecture, the antenna scale, and antenna hardware. From a network architecture perspective, cell-free massive MIMO (CF-mMIMO) distributes access points across wide areas to provide ubiquitous service without traditional cell boundaries. At the antenna-scale level, two prominent trends are observed: extremely large-scale MIMO (XL-MIMO), characterized by an increasing number of antenna elements, and holographic MIMO (HMIMO), featuring a denser arrangement of antenna elements. Both paradigms may exhibit pronounced spatial non-stationarity in the near field, in which the electromagnetic information theory can be harnessed to characterize their capabilities in manipulating the radio environment. Meanwhile, innovations in antenna hardware, including fluid/movable antennas and reconfigurable intelligent surfaces (RISs), are enabling wireless systems to actively adapt to and even customize evolving environments, improving flexibility and robustness. Despite significant progress, key challenges remain, including the following: accurate system modeling under real-world conditions, innovative signal processing for advanced MIMO technologies, and intelligent resource allocation by AI-driven methods. This Special Issue invites contributions that address these challenges and advance the practical implementation of next-generation MIMO systems.
Both original research articles and reviews are welcome. Topics include (but are not limited to) the following:
- CF-mMIMO/XL-MIMO/HMIMO/RIS system design, algorithms, and deployment strategies;
- Fluid/movable antenna- and RIS-empowered CF-mMIMO/XL-MIMO/HMIMO;
- Performance analysis of CF-mMIMO/XL-MIMO/HMIMO/RIS under real-world conditions;
- Advanced signal processing for CF-mMIMO/XL-MIMO/HMIMO/RIS;
- Intelligent resource allocation for CF-mMIMO/XL-MIMO/HMIMO/RIS by AI-driven methods;
- Joint optimization of advanced MIMO in terms of network architecture, antenna scale, and hardware.
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 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).
