Sensing for Reliable UAV Communication: Robust Trajectory and Resource Optimization in Low-Altitude Networks
Yifan Jiang, Qingqing Wu, Hongxun Hui +3
In low-altitude wireless networks, sensing-aided communication has emerged as a promising integrated sensing and communication (ISAC) paradigm for unmanned aerial vehicle (UAV) tra…
Two-Scale Spatial Deployment for Cost-Effective Wireless Networks via Cooperative IRSs and Movable Antennas
Ying Gao, Qingqing Wu, Ziyuan Zheng +4
This paper proposes a two-scale spatial deployment strategy to ensure reliable coverage for multiple target areas, integrating macroscopic intelligent reflecting surfaces (IRSs) an…
Cooperative Rotatable IRSs for Wireless Communications: Joint Beamforming and Orientation Optimization
Qiaoyan Peng, Qingqing Wu, Guangji Chen +3
Rotatable intelligent reflecting surfaces (IRSs) introduce a new degree of freedom (DoF) for shaping wireless propagation by adaptively adjusting the orientation of IRSs. This pape…
Rotatable IRS Aided Wireless Communication
Qiaoyan Peng, Qingqing Wu, Guangji Chen +4
Rotatable intelligent reflecting surface (IRS) introduces a new spatial degree of freedom (DoF) by dynamically adjusting orientations without the need of changing its elements' pos…
RIS-Assisted NOMA with Partial CSI and Mutual Coupling: A Machine Learning Approach
Bile Peng, Karl-Ludwig Besser, Shanpu Shen +5
Non-orthogonal multiple access (NOMA) is a promising multiple access technique. Its performance depends strongly on the wireless channel property, which can be enhanced by reconfig…
