Structure-Aware Multimodal LLM Framework for Trustworthy Near-Field Beam Prediction
Mengyuan Li, Qianfan Lu, Jiachen Tian +5
In near-field extremely large-scale multiple-input multiple-output (XL-MIMO) systems, spherical wavefront propagation expands the traditional beam codebook into the joint angular-d…
Pioneering Scalable Prototyping for Mid-Band XL-MIMO Systems: Design and Implementation
Jiachen Tian, Yu Han, Zhengtao Jin +6
The mid-band frequency range, combined with extra large-scale multiple-input multiple-output (XL-MIMO), is emerging as a key enabler for future communication systems. Thanks to the…
Distributed U6G ELAA Communication Systems: Channel Measurement and Small-Scale Fading Characterization
Jiachen Tian, Zhengtao Jin, Xiayang Chen +4
The distributed upper 6 GHz (U6G) extra-large scale antenna array (ELAA) is a key enabler for future wireless communication systems, offering higher throughput and wider coverage,…
Keypoint Detection Empowered Near-Field User Localization and Channel Reconstruction
Mengyuan Li, Yu Han, Zhizheng Lu +3
In the near-field region of an extremely large-scale multiple-input multiple-output (XL MIMO) system, channel reconstruction is typically addressed through sparse parameter estimat…
