Site-Specific Learning for Low-Overhead Multi-User MIMO Beamforming
Cheng-Jie Zhao, Zhaolin Wang, Zongyao Zhao +1
A low-overhead site-specific multi-user multiple-input multiple-output (MU-MIMO) beamforming framework is proposed. Conventional limited-feedback MU-MIMO relies on channel state in…
Center-Fed Pinching Antenna System for Uplink Environment Sensing
Cong Yu, Xu Gan, Bo Ai +3
A center-fed pinching antenna system (C-PASS)-enabled uplink environment sensing framework is proposed. Through the center-fed framework, doubled degrees of freedom is achieved com…
SiFo: Wireless Foundation Model for Low-Overhead Site-Specific CSI Feedback
Cheng-Jie Zhao, Zhaolin Wang, Zongyao Zhao +1
SiFo, a wireless foundation model-based framework, is proposed for low-overhead site-specific channel state information (CSI) feedback. In 3GPP NR, Type-II feedback provides an exp…
Agent-Native Wireless Communications: Architecture, Opportunities, and the Road Ahead
Yuanwei Liu, Xu Gan, Zhaolin Wang +3
Future wireless networks are moving toward autonomous service operation, where network control and resource management need to respond to time-varying radio conditions and evolving…
Dual-Scale Antenna Deployment for Pinching Antenna Systems
Xu Gan, Zhaolin Wang, Yuanwei Liu
A dual-scale deployment (DSD) framework is proposed for pinching antenna systems (PASS), under which four protocols are provided. 1) For the coarse-scale deployment, the pinching a…
Joint Segment Activation and Antenna Placement for Uplink SWAN Systems
Songnan Gu, Zhenqiao Cheng, Hao Jiang +3
This article analyzes the achievable sum-rate of multiuser uplink segmented waveguide-enabled pinching-antenna systems (SWANs). To unveil system-design insights, an upper bound on…
