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 Transmission Strategies for CoMP Downlink - Overview, Extension, and Numerical Comparison
Kien-Giang Nguyen, Oskari Tervo, Quang-Doanh Vu +2
This paper focuses on energy-efficient coordinated multi-point (CoMP) downlink in multi-antenna multi-cell wireless communications systems. We provide an overview of transmit beamf…
Globally Optimal Beamforming Design for Downlink CoMP transmission with Limited Backhaul Capacity
Kien-Giang Nguyen, Quang-Doanh Vu, Markku Juntti +1
This paper considers a multicell downlink channel in which multiple base stations (BSs) cooperatively serve users by jointly precoding shared data transported from a central proces…
Energy Efficient Precoding C-RAN Downlink with Compression at Fronthaul
Kien-Giang Nguyen, Quang-Doanh Vu, Markku Juntti +1
This paper considers a downlink transmission of cloud radio access network (C-RAN) in which precoded baseband signals at a common baseband unit are compressed before being forwarde…
