Energy Efficiency Fairness for Multi-Pair Wireless-Powered Relaying Systems
Kien-Giang Nguyen, Quang-Doanh Vu, Le-Nam Tran +1
We consider a multi-pair amplify-and-forward relay network where the energy-constrained relays adopting time-switching protocol harvest energy from the radio frequency signals tran…
Energy Efficiency Maximization for C-RANs: Discrete Monotonic Optimization, Penalty, and l0-Approximation Methods
Kien-Giang Nguyen, Quang-Doanh Vu, Markku Juntti +1
We study downlink of multiantenna cloud radio access networks (C-RANs) with finite-capacity fronthaul links. The aim is to propose joint designs of beamforming and remote radio hea…
Energy-Efficient Multi-Cell Multigroup Multicasting with Joint Beamforming and Antenna Selection
Oskari Tervo, Le-Nam Tran, Harri Pennanen +3
This paper studies the energy efficiency and sum rate trade-off for coordinated beamforming in multi-cell multi-user multigroup multicast multiple-input single-output systems. We f…
