User-Centric Cell-Free Massive MIMO Enhanced by Fluid-Antenna Access Points: Uplink Analysis
Maryam Olyaee, Giovanni Interdonato, Stefano Buzzi
In this paper, we investigate cell-free massive MIMO (CF-mMIMO) systems in which access points (APs) are equipped with fluid antennas (FAs) and develop a comprehensive framework fo…
Differential Space-Time Block Coding for Phase-Unsynchronized Cell-Free MIMO Downlink
Marx M. M. Freitas, Giovanni Interdonato, Stefano Buzzi
In the downlink of CF-mMIMO systems, spectral efficiency gains critically rely on joint coherent transmission, as all APs must align their transmitted signals in phase at the UE. A…
Evaluating the Performance of Reconfigurable Intelligent Base Stations through Ray Tracing
Sina Beyraghi, Giovanni Interdonato, Giovanni Geraci +2
Massive multiple-input multiple-output (mMIMO) is a key capacity-boosting technology in 5G wireless systems. To reduce the number of radio frequency (RF) chains needed in such syst…
Joint Optimization of Uplink and Downlink Power in Full-Duplex Integrated Access and Backhaul
Giovanni Interdonato, Silvia Mura, Marouan Mizmizi +2
We examine the performance of an Integrated Access and Backhaul (IAB) node as a range extender for beyond-5G networks, focusing on the significant challenges of effective power all…
Eliminating Phase Misalignments in Cell-Free Massive MIMO via Differential Transmission
Marx M. M. Freitas, Stefano Buzzi, Giovanni Interdonato
This paper proposes two approaches for overcoming access points' phase misalignment effects in the downlink of cell-free massive MIMO (CF-mMIMO) systems. The first approach is base…
Leveraging Line-of-Sight Propagation for Near-Field Beamfocusing in Cell-Free Networks
Georgios Mylonopoulos, Giovanni Interdonato, Stefano Buzzi +1
Cell-free (CF) massive multiple-input multiple-output (MIMO) is a promising approach for next-generation wireless networks, enabling scalable deployments of multiple small access p…
