Joint Beamforming and Illumination Pattern Design for Beam-Hopping LEO Satellite Communications
Jing Wang, Chenhao Qi, Shui Yu +1
Since hybrid beamforming (HBF) can approach the performance of fully-digital beamforming (FDBF) with much lower hardware complexity, we investigate the HBF design for beam-hopping…
Refracting Reconfigurable Intelligent Surface Assisted URLLC for Millimeter Wave High-Speed Train Communication Coverage Enhancement
Changzhu Liu, Ruisi He, Yong Niu +3
High-speed train (HST) has garnered significant attention from both academia and industry due to the rapid development of railways worldwide. Millimeter wave (mmWave) communication…
Sum Rate Maximization under AoI Constraints for RIS-Assisted mmWave Communications
Ziqi Guo, Yong Niu, Shiwen Mao +4
The concept of age of information (AoI) has been proposed to quantify information freshness, which is crucial for time-sensitive applications. However, in millimeter wave (mmWave)…
Robust Train-to-Train Transmission Scheduling in mmWave Band for High Speed Train Communication Systems
Yunhan Ma, Yong Niu, Shiwen Mao +5
Demands for data traffic in high-speed railway (HSR) has increased drastically. The increasing entertainment needs of passengers, safety control information exchanges of trains, et…
Joint Optimization of Resource Allocation and User Association in Multi-Frequency Cellular Networks Assisted by RIS
Yuanyuan Qiao, Yong Niu, Zhu Han +5
Due to the development of communication technology and the rise of user network demand, a reasonable resource allocation for wireless networks is the key to guaranteeing regular op…
