Demo: Vision-Language Model-Guided Online Calibration of an Electromagnetic Digital Twin
Zerui Kang, Yishen Lim, Zhouyou Gu +4
An electromagnetic (EM) digital twin gives mobile robots wireless situational awareness but depends on material conductivities that change with the environment. Online calibration…
Low-Rank Prior-Guided Rank-One Sensing for Efficient CSI Feedback
Shunpu Tang, Qianqian Yang, Seung-Woo Ko +1
Downlink channel state information (CSI) feedback is essential for frequency-division duplex massive MIMO, yet the feedback overhead grows rapidly with the numbers of antennas and…
Optimal Movable-Antenna Control for Multi-Path Sensing Guided by Prior AoA Statistic
Jaehong Kim, Changsheng You, Jihong Park +1
Multi-path sensing, which aims to extract the geometric attributes of multiple propagation paths, is expected to be a key functionality of 6G. A movable antenna (MA) can enable thi…
Semantics-Aware Hierarchical Token Communication: Clustering, Bit Mapping, and Power Allocation
Jihoon Lee, Seungeun Oh, Jihong Park +2
Despite the rise of token communication (TokCom) as a new paradigm beyond traditional bit communication, existing approaches have primarily adopted artificial intelligence (AI)-cen…
Prior-Guided Movable Antenna Control for Agile Multi-Path Sensing (extended version)
Jaehong Kim, Jihong Park, Changsheng You +1
Multi-path sensing, which aims to extract the geometric attributes of multiple propagation paths, is expected to be a key functionality of 6G. A movable antenna (MA) can enable thi…
Hard/Soft NLoS Detection via Combinatorial Data Augmentation for 6G Positioning
Sang-Hyeok Kim, Seung Min Yu, Jihong Park +1
A key enabler for meeting the stringent requirements of 6G positioning is the ability to exploit site-dependent information governing line-of-sight (LoS) and non-line-of-sight (NLo…
Vision-Language-Model-Guided Differentiable Ray Tracing for Fast and Accurate Multi-Material RF Parameter Estimation
Zerui Kang, Yishen Lim, Zhouyou Gu +3
Accurate radio-frequency (RF) material parameters are essential for electromagnetic digital twins in 6G systems, yet gradient-based inverse ray tracing (RT) remains sensitive to in…
Near-Field Localization with RIS via Two-Dimensional Signal Path Classification
Jeongwan Kang, Seung-Woo Ko, Sunwoo Kim
In this paper, we propose two-dimensional signal path classification (2D-SPC) for reconfigurable intelligent surface (RIS)-assisted near-field (NF) localization. In the NF regime,…
