Beyond Beamforming: Phase-and-Gain Channel Shaping via Rotatable Antenna Arrays
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +2
This paper investigates geometry-reconfigurable transmission for multiuser communication systems enabled by a rotatable antenna array. In contrast to conventional fixed arrays, the…
Multi-User MIMO with Rotatable Antennas and IRS: Joint Antenna Boresight and IRS Orientation Design
Guoying Zhang, Qingqing Wu, Ziyuan Zheng +5
In this paper, we investigate an intelligent reflecting surface (IRS)-assisted multi-user system, where the base station (BS) employs rotatable antennas (RAs) and the IRS can adjus…
Two-Timescale Design for Rotatable-Antenna Systems With Imperfect CSI: Rate Analysis and Orientation Optimization
Ziyuan Zheng, Qingqing Wu, Wen Chen
This paper studies uplink multiuser MIMO with a rotatable antenna (RA) array under imperfect channel state information (CSI), where each base-station antenna can adjust its boresig…
Joint Transmit and Receive Antenna Orientation Design for Secure MIMO Communications
Ailing Zheng, Qingqing Wu, Xingxiang Peng +4
Physical layer security (PLS) is a promising paradigm for safeguarding 6G wireless networks by exploiting the inherent characteristics of wireless channels. However, the efficiency…
Joint Transceiver Orientation Optimization for Rotatable-Antenna MIMO Capacity Maximization
Zheng Ailing, Wu Qingqing, Peng Xingxiang +3
Conventional multiple-input multiple-output (MIMO) systems mainly rely on fixed antenna arrays, which limits their capability to adapt the effective channel matrix to the propagati…
Low-Altitude Reflection via UAV-Mounted Rotatable IRS
Zhenwei Jiang, Ziyuan Zheng, Qingqing Wu +3
Low-altitude network is a key enabler for extending coverage and recovering connectivity in 6G systems, especially when terrestrial infrastructure is unavailable. This paper studie…
