AP Association for RHS-Enabled Cell-Free Uplink MIMO in Industrial Indoor UAV Networks
Liangshun Wu, Wen Chen, Zhendong Li +2
Indoor industrial UAV uplink networks face serious blockage and shadowing from shelves, metal equipment, and production facilities. UAVs are also often clustered and fly along simi…
Joint Trajectory, RIS, and Computation Offloading Optimization via Decentralized Model-Based PPO in Urban Multi-UAV Mobile Edge Computing
Liangshun Wu, Jianbo Du, Junsuo Qu
Efficient computation offloading in multi-UAV edge networks becomes particularly challenging in dense urban areas, where line-of-sight (LoS) links are frequently blocked and user d…
Coupling-Aware RHS Beamforming for Wideband Multi-User Sum Rate Maximization
Liangshun Wu, Wen Chen
Wideband multi-user transmission assisted by reconfigurable holographic surfaces (RHSs) is fundamentally limited by mutual coupling effect among densely packed sub-wavelength radia…
THz RHS Transceiver for Low-Latency Multi-User VR Transmission with MEC
Liangshun Wu, Wen Chen, Honghao Wang +2
This paper investigates a Terahertz (THz)-enabled mobile edge computing (MEC)-assisted virtual reality (VR) system using reconfigurable holographic surfaces (RHS) as transceiver fo…
Green Emergency Communications in RIS- and MA-Assisted Multi-UAV SAGINs: A Partially Observable Reinforcement Learning Approach
Liangshun Wu, Wen Chen, Shunqing Zhang +2
In post-disaster space-air-ground integrated networks (SAGINs), terrestrial infrastructure is often impaired, and unmanned aerial vehicles (UAVs) must rapidly restore connectivity…
Channel Ordering for Fairness in Elastic Optical Networks via a LLM-Guided Bottleneck TSP Solver
Liangshun Wu, Wen Chen, Qingqing Wu
In flexible-grid elastic optical networks (EONs), the ordering of frequency channels plays a crucial role in managing inter-channel interference and ensuring signal quality. We add…
