Where to Perform Channel Measurements for CKM Construction: A Random Field Theory Analysis
Yuxuan Song, Yong Zeng, Xiping Wu +3
Channel knowledge map (CKM) is regarded as a promising technology for future sixth-generation (6G) networks, facilitating environmental-aware wireless communication, sensing, and l…
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…
Antenna Orientation Optimization for Rotatable Antenna-Enabled ISAC Systems
Qingjie Wu, Beixiong Zheng, Guangchi Zhang +1
Non-fixed flexible antenna architectures, such as fluid antenna system (FAS), movable antenna (MA), and pinching antenna, have garnered significant interest in recent years. In thi…
Sensing-Assisted Secure Communication in MA-Aided ISAC: CRB Analysis and Robust Design
Yaxuan Chen, Guangchi Zhang, Miao Cui +3
A core challenge in physical-layer security is the difficulty of obtaining the channel state information (CSI) of potential eavesdroppers. The inherent sensing functionality of int…
DUGC-VRNet: Joint VR Recognition and Channel Estimation for Spatially Non-Stationary XL-MIMO
Jinhao Nie, Guangchi Zhang, Miao Cui +2
In this letter, we address spatially non-stationary near-field channel estimation for extremely large-scale multiple-input multiple-output (XL-MIMO) systems with a hybrid combining…
Enhancing User Fairness in Two-Layer RSMA: A Movable Antenna Approach
Ji Luo, Yaxuan Chen, Guangchi Zhang +3
Enhancing user fairness in advanced multi-user systems like two-layer rate-splitting multiple access (RSMA) is a critical yet challenging task. This letter proposes a novel movable…
