Minimizing Energy Consumption based on Waste Factor in Multi-user Multi-relay Systems
Nurullah Sevim, Mostafa Ibrahim, Sabit Ekin +1
The escalating energy demands of modern wireless networks make energy-efficient system design a central challenge for future 6G deployments. Relay-assisted communication has long b…
Quantifying the Reality Gap for RL-Based UAV Placement at mmWave and Sub-THz
Abdullateef Almohamad, Mostafa Ibrahim, Sabit Ekin +1
Reinforcement learning (RL) policies for unmanned aerial vehicle (UAV) placement in mmWave and sub-terahertz networks are typically trained on simplified analytical channels. We qu…
Bypassing the CSI Bottleneck: MARL-Driven Spatial Control for Reflector Arrays
Hieu Le, Oguz Bedir, Mostafa Ibrahim +2
Reconfigurable Intelligent Surfaces (RIS) are pivotal for next-generation smart radio environments, yet their practical deployment is severely bottlenecked by the intractable compu…
Learning to Focus: CSI-Free Hierarchical MARL for Reconfigurable Reflectors
Hieu Le, Mostafa Ibrahim, Oguz Bedir +2
Reconfigurable Intelligent Surfaces (RIS) have the potential to engineer smart radio environments for next-generation millimeter-wave (mmWave) networks. However, the prohibitive co…
Learning to Reflect: Hierarchical Multi-Agent Reinforcement Learning for CSI-Free mmWave Beam-Focusing
Hieu Le, Oguz Bedir, Mostafa Ibrahim +2
Reconfigurable Intelligent Surfaces promise to transform wireless environments, yet practical deployment is hindered by the prohibitive overhead of Channel State Information (CSI)…
