About this opportunity:

Energy efficiency is a defining key performance indicator (KPI) for 6G. The radio access network (RAN) is a major part of a mobile network operator’s (MNO’s) energy use, and much of that energy is spent even at low traffic because the network is dimensioned for peak load. Many of the decisions that keep hardware active are taken at Layer 3 (L3) — the control plane — through radio resource control (RRC) connection states, admission control, and mobility. Today these mechanisms are mostly rule-based and tuned for performance, leaving energy-saving potential on the table. As 6G becomes AI-native, data-driven L3 control that jointly optimizes quality of service (QoS) and energy is a promising but challenging direction.

What you will do:

• Reduce network energy consumption through smarter L3 control while respecting QoS guarantees, and quantify the energy–performance trade-off.
• Model how L3 decisions (RRC states, cell activation/sleep, admission control) map to network energy consumption using a system-level simulator.
• Implement a rule-based baseline aligned with 3GPP standards and design energy-aware policies, including a reinforcement-learning policy that coordinates cell sleep with RRC.
• Evaluate across load levels and produce energy–performance trade-off curves (e.g., watts per bit vs. latency, throughput, and SLA violations).
• Conclude with recommendations for energy-aware 6G L3 design and a presentation of results.

The skills you bring:

• Master´s student in electrical engineering, computer science, or similar
• Programming experience in Python (and/or C++, Rust)
• Basic machine learning and/or reinforcement learning
• Interest in 3GPP protocol layers (RRC/L3)
• Strong teamwork skills; ideal for two students with a split focus:
• One leaning toward protocols/systems
• One leaning toward ML
