Self-Interference-Aware AS-Assisted Tri-Hybrid Beamforming for Full-Duplex Massive MIMO
Yuanzhe Gong, Cheng-Jie Zhao, Tho Le-Ngoc
This paper proposes a tri-hybrid beamforming (tri-HBF) scheme with antenna-selection (AS)-based reconfigurable sub-arrays for full-duplex (FD) massive multiple-input multiple-outpu…
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…
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…
Generative Site-Specific Beamforming via Information-Maximizing Codebook
Cheng-Jie Zhao, Zhaolin Wang, Yuanwei Liu
A novel generative site-specific beamforming (GenSSBF) framework is proposed, which integrates a site-information-maximizing (SIM) codebook with a conditional flow matching (CFM)-b…
Generative Site-Specific Beamforming for Next-Generation Spatial Intelligence
Zhaolin Wang, Zihao Zhou, Cheng-Jie Zhao +1
This article proposes generative site-specific beamforming (GenSSBF) for next-generation spatial intelligence in wireless networks. Site-specific beamforming (SSBF) has emerged as…
Tri-Hybrid Beamforming Design for Fully-Connected Pinching Antenna Systems
Cheng-Jie Zhao, Zhaolin Wang, Hyundong Shin +1
A novel fully-connected (FC) tri-hybrid beamforming (THB) architecture is proposed for pinching antenna systems (PASS). In contrast to conventional sub-connected (SC) PASS, the pro…
