Sensing User's Activity, Channel, and Location with Near-Field Extra-Large-Scale MIMO
Li Qiao, Anwen Liao, Zhuoran Li +7
This paper proposes a grant-free massive access scheme based on the millimeter wave (mmWave) extra-large-scale multiple-input multiple-output (XL-MIMO) to support massive Internet-…
Sensing User's Channel and Location with Terahertz Extra-Large Reconfigurable Intelligent Surface under Hybrid-Field Beam Squint Effect
Zhuoran Li, Zhen Gao, Tuan Li
This paper investigates the sensing of user's uplink channel and location in terahertz extra-large reconfigurable intelligent surface (XL-RIS) systems, where the unique hybrid far-…
Quasi-Synchronous Random Access for Massive MIMO-Based LEO Satellite Constellations
Keke Ying, Zhen Gao, Sheng Chen +5
Low earth orbit (LEO) satellite constellation-enabled communication networks are expected to be an important part of many Internet of Things (IoT) deployments due to their unique a…
Reconfigurable Massive MIMO: Harnessing the Power of the Electromagnetic Domain for Enhanced Information Transfer
Keke Ying, Zhen Gao, Sheng Chen +4
The capacity of commercial massive multiple-input multiple-output (mMIMO) systems is constrained by the limited array aperture at the base station, and cannot meet the ever-increas…
