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…
Semi-Passive IRS Enabled Sensing with Group Movable Sensors
Qiaoyan Peng, Qingqing Wu, Wen Chen +4
The performance of the sensing system is limited by the signal attenuation and the number of receiving components. In this letter, we investigate the sensor position selection in a…
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…
Active IRS Assisted Joint Uplink and Downlink Communications
Qiaoyan Peng, Qingqing Wu, Guangji Chen +2
In this paper, we investigate an intelligent reflecting surface (IRS) aided wireless communication system, where active IRSs (AIRSs) are deployed to assist communication between a…
Flexible XL-MIMO via Array Configuration Codebook: Codebook Design and Array Configuration Training
Haiquan Lu, Hongqi Min, Yong Zeng +1
XL-MIMO emerges as a promising technology to achieve unprecedented enhancements in spectral efficiency and spatial resolution, via orders-of-magnitude increase in the antenna array…
Wireless Communication for Low-Altitude Economy with UAV Swarm Enabled Two-Level Movable Antenna System
Haiquan Lu, Yong Zeng, Shaodan Ma +3
Unmanned aerial vehicle (UAV) is regarded as a key enabling platform for low-altitude economy, due to its advantages such as 3D maneuverability, flexible deployment, and LoS air-to…
Joint Size and Placement Optimization for IRS-Aided Communications with Active and Passive Elements
Qiaoyan Peng, Qingqing Wu, Wen Chen +6
Different types of intelligent reflecting surfaces (IRS) are exploited for assisting wireless communications. The joint use of passive IRS (PIRS) and active IRS (AIRS) emerges as a…
