Holographic Beamforming for Semantic Communication
Shuhao Zeng, Haobo Zhang, Su Wang +5
Holographic beamforming enabled by metamaterial antennas has been proposed to facilitate spatial multiplexing at low hardware cost and low power consumption. However, existing holo…
Personalized 3D Spatiotemporal Trajectory Privacy Protection with Differential and Distortion Geo-Perturbation
Minghui Min, Yulu Li, Gang Li +4
The rapid advancement of location-based services (LBSs) in three-dimensional (3D) domains, such as smart cities and intelligent transportation, has raised concerns over 3D spatiote…
Empowering Embodied AI in 6G Networks: Architecture, Enablers, and Open Challenges
Junaid Sajid, Sheikh Salman Hassan, Wenshuai Liu +7
Embodied artificial intelligence (AI) is emerging as a key driver of the sixth-generation (6G) wireless networks by enabling agents that continuously perceive, communicate, and act…
Road Network-Aware Personalized Trajectory Protection with Differential Privacy under Spatiotemporal Correlations
Minghui Min, Jiahui Liu, Mingge Cao +4
Location-Based Services (LBSs) offer significant convenience to mobile users but pose significant privacy risks, as attackers can infer sensitive personal information through spati…
Simultaneously Exposing and Jamming Covert Communications via Disco Reconfigurable Intelligent Surfaces
Huan Huang, Hongliang Zhang, Yi Cai +3
Covert communications provide a stronger privacy protection than cryptography and physical-layer security (PLS). However, previous works on covert communications have implicitly as…
Reconfigurable Holographic Surface: A New Paradigm for Ultra-Massive MIMO
Boya Di, Hongliang Zhang, Rui Zhang +2
Evolving from massive multiple-input multiple-output (MIMO) in current 5G communications, ultra-massive MIMO emerges as a seminal technology for fulfilling more stringent requireme…
