Unexpected Far-Near-Far Transition in Mobile Near Field Terahertz Communications
Peng Zhang, Hanmei Yuan, Zhe Wang +2
At THz frequencies, the radiative near-field distance can be sufficiently large to matter in real deployments. Existing near-field formulas are often understood in a simple way: as…
Statistics Approximation-Enabled Distributed Beamforming for Cell-Free Massive MIMO
Zhe Wang, Emil Björnson, Jiayi Zhang +3
We study a distributed beamforming approach for cell-free massive multiple-input multiple-output networks, referred to as Global Statistics & Local Instantaneous information-based…
Low-Complexity Distributed Combining Design for Near-Field Cell-Free XL-MIMO Systems
Zhe Wang, Jiayi Zhang, Bokai Xu +4
In this paper, we investigate the low-complexity distributed combining scheme design for near-field cell-free extremely large-scale multiple-input-multiple-output (CF XL-MIMO) syst…
Flexible MIMO for Future Wireless Communications: Which Flexibilities are Possible?
Zhe Wang, Jiayi Zhang, Bokai Xu +3
In conventional multiple-input multiple-output (MIMO), static array configurations struggle in dynamic environments, and further antenna scaling is bounded by cost, energy, and foo…
Large Language Model Empowered Next-Generation MIMO Networks: Fundamentals, Challenges, and Visions
Zhe Wang, Jiayi Zhang, Hongyang Du +4
Next-generation Multiple-Input Multiple-Output (MIMO) is expected to be intelligent and scalable. In this paper, we study Large Language Model (LLM)-enabled next-generation MIMO ne…
ROMA: ROtary and Movable Antenna
Jiayi Zhang, Wenhui Yi, Bokai Xu +3
The rotary and movable antenna (ROMA) architecture represents a next-generation multi-antenna technology that enables flexible adjustment of antenna position and array rotation ang…
