Simultaneous Indoor and Outdoor Coverage with Conformal Intelligent Omni-Surface
Yiqi Chen, Xiaoming She, Jianchi Zhu +3
Seamless indoor--outdoor coverage conventionally relies on coordinated outdoor macro cells and indoor small cells, incurring high deployment and backhaul costs. Intelligent omni-su…
Spatiotemporal Tracking in Cooperative ISAC Networks: A Stochastic Geometry Framework
Bowen Wang, Nanxi Li, Jingzhou Wu +2
We adopt a stochastic-geometry framework to study continuous target tracking in integrated sensing and communication (ISAC) networks, with base-station locations modelled as a Pois…
Exploiting Movable Antennas in Multicast Communications
Zhenqiao Cheng, Nanxi Li, Jianchi Zhu +2
This article investigates the integration of movable antennas (MAs) into multicast communication systems. By discretizing the motion of the MAs, a novel MA-assisted multicast trans…
Enabling Secure Wireless Communications via Movable Antennas
Zhenqiao Cheng, Nanxi Li, Jianchi Zhu +3
A pioneering secure transmission scheme is proposed, which harnesses movable antennas (MAs) to optimize antenna positions for augmenting the physical layer security. Particularly,…
Channel Estimation and Training Design for Active RIS Aided Wireless Communications
Hao Chen, Nanxi Li, Ruizhe Long +1
Active reconfigurable intelligent surface (ARIS) is a newly emerging RIS technique that leverages radio frequency (RF) reflection amplifiers to empower phase-configurable reflectio…
Sum-Rate Maximization for Movable Antenna Enabled Multiuser Communications
Zhenqiao Cheng, Nanxi Li, Jianchi Zhu +1
A novel multiuser communication system with movable antennas (MAs) is proposed, where the antenna position optimization is exploited to enhance the downlink sum-rate. The joint opt…
