For the Broadband & Broadcast department in Erlangen, the Fraunhofer Institute for Integrated Circuits IIS is currently seeking
Interns for the Topic: NR Uplink System Level Simulator

The Broadband & Broadcast (BB) department is active in the areas of mobile communications, satellite communications, Internet-of-Things and automotive communication systems. We take new concepts and algorithms from theory, implement them and test them in simulations and in prototypes in our labs and in the field. For instance, we develop a 5G New Radio (NR) testbed for various applications like V2X and industrial communication. In short, the BB department establishes a bridge between communication theory and its employment in practice.

Your Tasks
Evaluating the performance of the NR protocol stack on different levels is of great interest and has a valuable potential on further improvement and development. The main motivation is to migrate the current LTE Uplink (UL) System Level Simulator (SLS) towards NR, so that services and use cases of NR can be simulated.
The proposed NR SLS should support key features such as different subcarrier spacing, different slot configurations and grant free transmission, with a focus on URLLC use case.

Your responsibilities: You …

  • understand the legacy MAC and PHY-abstraction in LTE
  • understand and implement NR MAC in SLS
  • implement NR PHY-abstraction features
  • produce throughput and latency simulation results complying with TR 37.910 “Study on Self Evaluation towards IMT-2020 Submission“.

Was du mitbringst

  • You have knowledge in wireless communications
  • You have knowledge in Matlab programming (mandatory)
  • You are familiar with LTE/5G (advantageous)

Was du erwarten kannst

  • An open and cooperative working environment
  • Collaboration in interesting and innovative projects
  • Many opportunities to gain practical experience and attend seminars
  • Flexibility concerning your working hours


Applications are possible in German and English. Please include a cover letter, your CV and your latest transcripts of records (as PDF) and quote ID number 46524. Address your application to Nina Wörlein.
