Optimization of CF-mMIMO Systems for the Coexistence between eMBB+ and mMTC+: From Analytical to GNN-Aided Designs
Sergi Liesegang, Lou Salaün, Chung Shue Chen +1
This paper investigates uplink multiple access for the coexistence of enhanced mobile broadband+ (eMBB+) and massive machine-type communications+ (mMTC+) in terminal-centric cell-f…
A Comparison Between Co-Located and Distributed MIMO Deployments in OFDM-ISAC Networks
Maryam Darabi, Sergi Liesegang, Emanuele Grossi +1
This paper investigates network-level integrated sensing and communication (ISAC) under two fundamentally different topology configurations: cell-free massive MIMO (CF-mMIMO) and m…
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…
Coexistence of eMBB+ and mMTC+ in Uplink Cell-Free Massive MIMO Networks
Sergi Liesegang, Stefano Buzzi
This paper tackles the problem of designing proper uplink multiple access schemes for coexistence between enhanced mobile broadband+ (eMBB+) users and massive machine-type communic…
Differential Space-Time Block Coding for Phase-Unsynchronized Cell-Free MIMO Downlink
Marx M. M. Freitas, Giovanni Interdonato, Stefano Buzzi
In the downlink of a cell-free massive multiple-input multiple-output (CF-mMIMO) system, spectral efficiency gains critically rely on joint coherent transmission, as all access poi…
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…
