Power Control in Cell-Free Massive MIMO Networks for UAVs URLLC under the Finite Blocklength Regime
Mohamed Elwekeil, Alessio Zappone, Stefano Buzzi
In this paper, we employ a user-centric (UC) cell-free massive MIMO (CFmMIMO) network for providing ultra reliable low latency communication (URLLC) when traditional ground users (…
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…
Synergistic Benefits in IRS- and RS-enabled C-RAN with Energy-Efficient Clustering
Kevin Weinberger, Alaa Alameer Ahmad, Aydin Sezgin +1
The potential of intelligent reflecting surfaces (IRSs) is investigated as a promising technique for enhancing the energy efficiency of wireless networks. Specifically, the IRS ena…
Energy Efficiency Optimization of Reconfigurable Intelligent Surfaces with Electromagnetic Field Exposure Constraints
Alessio Zappone, Marco Di Renzo
This work considers the problem of energy efficiency maximization in a RIS-based communication link, subject to not only the conventional maximum power constraints, but also additi…
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…
Intelligent Reflecting Surface Enabled Random Rotations Scheme for the MISO Broadcast Channel
Qurrat-Ul-Ain Nadeem, Alessio Zappone, Anas Chaaban
