Average AoI Minimization for Energy Harvesting Relay-aided Status Update Network Using Deep Reinforcement Learning
Sin-Yu Huang, Kuang-Hao, Liu
A dual-hop status update system aided by energy harvesting (EH) relays with finite data and energy buffers is studied in this work. To achieve timely status updates, the best relay…
QoS-Aware Downlink Beamforming for Joint Transmission in Multi-Cell Networks
Chen-Yen Lin, Kuang-Hao, Liu
Multi-cell cooperation is an effective means to improve service quality to cellular users. Existing work primarily focuses on interference cancellation using all the degrees of fre…
On the Channel Correlation in Reconfigurable Intelligent Surface-Aided System
Kuang-Hao, Liu
This works explores the correlation between channels in reconfigurable intelligent surface (RIS)-aided communication systems. In this type of system, an RIS made up of many passive…
Low-complexity Joint Beamforming for RIS-Aided Multi-User Downlink over Correlated Channels
Yu-Tse Wu, Kuang-Hao Liu
This paper considers the reconfigurable intelligent surface (RIS)-assisted multi-user communications, where an RIS is used to assist the base station (BS) for serving multiple user…
Quasi-Degradation Probability of Two-User NOMA over Rician Fading Channels
Kuang-Hao Liu
Non-orthogonal multiple access (NOMA) has a great potential to offer a higher spectral efficiency of multi-user wireless networks than orthogonal multiples access (OMA). Previous w…
Battery-Aware Relay Selection for Energy Harvesting Cooperative Networks
Yu-Hsien Lee, Kuang-Hao Liu
The use of energy harvesting (EH) nodes as cooperative relays is an emerging solution for enabling green wireless systems. In this paper, we consider multiple EH relay nodes harves…
