: Accurate evaluation of radio access performance is essential for the design and optimization of ultra-dense fifth-generation (5G) networks, where the interactions between multiple users, base stations, and interference sources become highly complex. This paper proposes a comprehensive System-Level Simulation (SLS) fr...

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 vehicle (UAV) communications operating under high mobility, with reliability and fairness as the primary design targets.A base station with a...

This paper investigates hybrid beamforming for multi-user large multiple-input multiple-output millimeter-wave unmanned aerial vehicle (UAV) downlink systems under mobility-induced channel aging and delayed beam-training feedback. Analog beam selection from compact delayed reports is a partial-observation decision, whi...

Near-field simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) systems enable full-space coverage, but dense multiuser operation requires active-user grouping under practical stream or RF-chain constraints. Gain-based or proportional-fair scheduling may over-serve strong users, whil...
