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…
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…
Artificial Intelligence for Spatially Reconfigurable Antennas: Movable, Fluid, and Pinching Antenna Systems
Nguyen Cong Luong, Zeping Sui, Thai-Hoc Vu +10
Recently, sixth-generation (6G) wireless networks have moved beyond fixed-array designs toward antenna architectures that can adapt their spatial configuration to specific environm…
