MA-HEAD-Net: Adaptive Rule-Guided Multi-Agent DRL for AoI Minimization in UAV-Assisted Emergency Networks
Yixin Zhang, Zhuohui Yao, Wenchi Cheng +1
In post-disaster scenarios, unmanned aerial vehicles (UAVs) are critical for establishing emergency communication networks. For time-critical rescue missions, information freshness…
3D Spherical Fluid Antennas for Spatially Reconfigurable Communications
Wenchi Cheng, Hongyun Jin, Zhuohui Yao
As sixth-generation (6G) wireless systems evolve toward higher frequency bands, large-scale antenna arrays, and intelligent interaction with the wireless environment, conventional…
Fundamental for Delay and Reliability Guarantees for Emergency UAV
Wenchi Cheng, Jingqing Wang, Zhuohui Yao +1
To support mission-critical services in emergency scenarios, wireless networks are required to provide stringent guarantees under massive Ultra-Reliable Low-Latency Communications…
Location-Aided Distributed Beamforming for Near-Field Communications with Element-Wise RIS
Xiao Zheng, Wenchi Cheng, Jingqing Wang +2
Active reconfigurable intelligent surface (RIS) emerges as an effective technique to resist the double-fading attenuation of passive RIS. By embedding with power harvesting functio…
Post-disaster Max-Min Rate Optimization for Multi-UAV RSMA Network in Obstacle Environments
Qingyang Wang, Zhuohui Yao, Wenchi Cheng +1
This paper proposes a rate-splitting multiple access (RSMA) transmission scheme to maximize the minimum achievable rate among ground users for emergency communications in post-disa…
RSMA Assisted ISAC With Hybrid Beamforming
Zhuohui Yao, Wenchi Cheng, Liping Liang +2
The harsh environment and scarce resources post-disaster drive the equipment to be miniaturized and portable. Based on this, integrated sensing and communication (ISAC) systems pla…
