RIS-aided Massive MIMO: Achieving Large Multiplexing Gains with non-Large Arrays
Stefano Buzzi, Carmen D'Andrea, Giovanni Interdonato
This paper considers an antenna structure where a (non-large) array of radiating elements is placed at short distance in front of a reconfigurable intelligent surface (RIS). We pro…
Deep Learning-Based Power Control for Uplink Cell-Free Massive MIMO Systems
Yongshun Zhang, Jiayi Zhang, Yu Jin +2
In this paper, a general framework for deep learning-based power control methods for max-min, max-product and max-sum-rate optimization in uplink cell-free massive multiple-input m…
Integrated Sensing and Communications: Towards Dual-functional Wireless Networks for 6G and Beyond
Fan Liu, Yuanhao Cui, Christos Masouros +4
As the standardization of 5G is being solidified, researchers are speculating what 6G will be. Integrating sensing functionality is emerging as a key feature of the 6G Radio Access…
Optimal Joint Beamforming and Power Control in Cell-Free Massive MIMO Downlink
Mohamed Elwekeil, Alessio Zappone, Stefano Buzzi
In this paper, a novel optimization model for joint beamforming and power control in the downlink (DL) of a cell-free massive MIMO (CFmMIMO) system is presented. The objective of t…
Beam Alignment in mmWave User-Centric Cell-Free Massive MIMO Systems
Stefano Buzzi, Carmen D'Andrea, Maria Fresia +1
The problem of beam alignment (BA) in a cell-free massive multiple-input multiple-output (CF-mMIMO) system operating at millimeter wave (mmWaves) carrier frequencies is considered…
RIS Configuration, Beamformer Design, and Power Control in Single-Cell and Multi-Cell Wireless Networks
Stefano Buzzi, Carmen D'Andrea, Alessio Zappone +3
Reconfigurable Intelligent Surfaces (RISs) are recently attracting a wide interest due to their capability of tuning wireless propagation environments in order to increase the syst…
