Job description

This PhD research aims to investigate beyond state-of-the art technology enablers for the next-generation cellular paradigm, called 6G. The main focus will be on Radio Access Network (RAN) optimisation mechanisms within the Open-RAN (O-RAN) framework to meet strict and diverse requirements of emerging use cases in the 6G era.

The research objectives include (but are not limited to): O-RAN based architectural integration of 5G/6G Terrestrial/Non-Terrestrial and Wi-Fi, development of advanced algorithms and optimisation techniques to enhance the performance and efficiency of the integrated RAN, spectrum management strategies for efficient utilisation of wireless resources and interference/jamming avoidance and methods for optimal unicast and multicast/broadcast transmissions, often empowering cutting edge AI/ML technologies such as Agentic AI, Wireless Physical Layer Foundation Model, etc..

The candidate will be validating and evaluating the developed mechanisms utilizing simulation tools and in-house cutting-edge cellular/Wi-Fi testbeds and tools.

Your main tasks will include:

  • Studying state-of-the-art techniques and benchmarks in the domain of the next generation O-RAN based wireless networks (including 6G both Terrestrial Network (TN) and Non-Terrestrial Network (NTN)(Satellite), and Wi-Fi)
  • Design and implement novel techniques for next generation cellular communications, including among others RAN optimization with a focus on intelligent radio resource allocation, interference/jamming avoidance, cross-technology optimization (6G TN/NTN, Wi-Fi), empowering cutting edge AI/ML technologies such as Agentic AI, Wireless Physical Layer Foundation Model, etc.
  • Collaborate towards a proof-of-concept implementation for testing and validating the created solutions using simulation and real-testbeds
  • Writing high-quality publications, targeting top journals and international conferences.
  • You assist in limited educational tasks of the research group.
  • Mentoring role by supervising master theses related to the subject of this PhD.

Your profile

We are looking for a highly creative and motivated PhD student with the following qualifications and skills:

  • You must have (or will receive in a few months) a Master’s degree in Computer Science Engineering, Master of Science in Information Engineering Technology, Master of Science in Electrical Engineering, or a related field.
  • You are interested to do research in an academic environment for a 4 years period in view of a PhD degree.
  • You have a strong background in wireless and mobile networks and machine learning
  • You have excellent coding skills; hands-on experience in programming languages, such as C++, Python, ….
  • You have strong analytical skills to interpret the obtained research results.
  • You are a team player and have strong communication skills.
  • You can commit to timing and milestones set forward by different research projects.
  • Your English is fluent (C1 CEFR level) both speaking and writing. 

Our offer

  • We offer a full-time position as a doctoral fellow, consisting of an initial period of 12 months, which - after a positive evaluation, will be extended to a total maximum of 48 months.
  • The fellowship amount is 100% of the net salary of an AAP member in equal family circumstances. The individual fellowship amount is determined by the Department of Personnel and Organization based on family status and seniority. A grant that meets the conditions and criteria of the regulations for doctoral fellowships is considered free of personal income tax. Click here for more information about our salary scales
  • All Ghent University staff members enjoy a number of benefits, such as a wide range of training and education opportunities, 36 days of holiday leave (on an annual basis for a full-time job) supplemented by annual fixed bridge days, bicycle allowance and eco vouchers.
