6G as It Is Actually Being Built: Insights from Early 3GPP Standardization
Ngo Hoang Tu, Huy T. Nguyen, Mao V. Ngo +3
As mobile communications cross the threshold from 5G to 6G, the 3GPP has entered a decisive phase. Following the Technical Specification Group (TSG) plenary meetings of June 2026 a…
FSS-UBrain: Multi-region Few-Shot Brain Tumor MRI Segmentation
Truong Viet Vu, Nguyen Phuc Nguyen, Dang Thi Thu Hang +4
Accurate delineation of whole tumor (WT), tumor core (TC), and enhancing tumor (ET) from multimodal magnetic resonance imaging remains challenging under limited annotation, cross-c…
OTFS-Enabled Delayed SINR-Feedback Power Control for Reliable and Fair High-Mobility UAV Communications
Thuan Van Le, Nguyen Cong Luong, Trong-Dai Hoang +4
This paper develops a power control framework driven by delayed signal-to-interference-plus-noise ratio (SINR) feedback for orthogonal time frequency space (OTFS) unmanned aerial v…
Mobility- and Feedback-Aware Multi-Level Conflict-Triggered Hybrid Beamforming for Multi-User mmWave UAV Systems
Thuan Van Le, Nguyen Cong Luong, Xingwang Li +2
This paper investigates hybrid beamforming for multi-user large multiple-input multiple-output millimeter-wave unmanned aerial vehicle (UAV) downlink systems under mobility-induced…
Feedback-Efficient Beam-User Association for Near-Field mmWave Hybrid Beamforming Systems
Thuan Van Le, Ngoc-Thanh Nguyen, Nam Van Dinh +4
Near-field multiuser hybrid beamforming (HBF) requires joint angle-distance codebooks whose size, and hence reporting overhead, grows with the array aperture. For the extremely lar…
Active STAR-RIS-Aided RSMA IoT Systems: Performance Analysis, Model-Based and Data-Driven Resource Allocation Frameworks
Ngo Hoang Tu, Vo Nguyen Quoc Bao, Tran Thien Thanh
STAR-RISs have emerged as a promising technology for achieving full-space signal coverage with low hardware complexity and energy consumption. In parallel, RSMA offers a flexible i…
Hierarchical Empirical-Bayes Naive Bayes: Minimax Smoothing and Calibration with AODE Extension
Nguyen Thai Anh, Truong Viet Vu, Tran Thien Thanh +2
The Naive Bayes (NB) classifier remains a standard choice for categorical data, yet its widely used smoothing rules, such as Laplace, Lidstone, Krichevsky-Trofimov, and the -est…
Hybrid Beamforming in Non-Terrestrial Networks: Architectures, Design Challenges, and Opportunities
Thuan Van Le, Nguyen Cong Luong, Huy T. Nguyen +6
Hybrid analog-digital beamforming (HBF) has emerged as a key enabling technology for non-terrestrial networks (NTNs), where large antenna arrays are required to compensate for seve…
