One or more PhD Stipends in Advanced Duplexing Solutions and Related Radio Resource Management (RRM) Enablers (8-21083)

At the Technical Faculty of IT and Design, Department of Electronic Systems, one or more PhD stipends in Advanced Duplexing Solutions and Related Radio Resource Management (RRM) Enablers are available within the general study programme Wireless Communications. The stipends are open for appointment from January 1, 2022, or soon as possible thereafter. In electronics engineering, Aalborg University is known worldwide for its high academic quality and the societal relevance of its research programmes. The Department of Electronic Systems consists of more than 200 employees, of which about 40 % are international and about 90 are enrolled PhD students. The Department hosts 620 students. The Department's excellent research infrastructures and facilities accentuate its global position in teaching and research. The Department's research centres around communication, antennas, control systems, AI, sound, cybersecurity and robotics. The Department plays an active role in translating discoveries and results into practical applications with industrial partners and IPR. The Department provides teaching for several BSc and MSc programmes using a problem- and project-based learning model.


Job description

Efficient service delivery of high bitrate services under bounded latency and reliability conditions is one of the goals for evolved 5G-Advanced and the upcoming 6G design. This is e.g. of high relevance for the emerging eXtended Reality (XR) and Cloud Gaming (CG) services, where enhanced QoS-aware radio resource allocation policies are needed to match the users’ throughput-latency-reliability requirements. This is particular challenging for unpaired bands with traditional time division duplexing (TDD), where each cell operate with exclusively downlink or uplink transmission at each time instant. Research on innovative duplexing schemes is therefore needed to allow simultaneous downlink and uplink transmissions in unpaired bands when needed. This calls for new solutions when it comes to radio resource management (RRM) such as scheduling, power control, interference mitigation as several system design considerations. The PhD study will study and develop solutions enabling more efficient duplexing schemes for the 5G-Advanced evolution, followed by migration towards 6G designs that may include further disruptive innovations. The PhD study is anticipated to cover the following aspects:

1) Design and analysis of novel duplexing schemes and related QoS-aware RRM solutions for demanding services with bounded throughput, latency, reliability requirements. Incl. potential usage of AI/ML based techniques for RRM optimizations.

2) Network deployments with sub-6GHz and/or mmWave usage will be in focus, assuming advanced base stations and terminals with sophisticated beamforming.

3) Aspects of different base station and terminal designs shall be considered, e.g. related to self-interference suppression capabilities, and also inter-cell interference mitigation.

4) System level performance assessment with high-degree of realism by means of simulations. Incl. realistic traffic models and detail modelling of the performance determining radio protocols and effects.

5) The PhD study will be conducted as part of a research collaboration with Nokia.

Expectations for the candidate:

  • Knowledge and experience with wireless access networks, incl. radio propagation basics and Layer 1-3 radio protocols, is required
  • Knowledge and experience with basic RRM features such QoS- and radio-aware scheduling, power control, interference mitigation, link adaptation, radio access
  • Knowledge of cellular technologies such as 5G New Radio
  • Experience with performance analysis and system-level simulations, including software programming skills (MATLAB and C++)
  • Analytical skills, including abilities to address complicated problems, division of those into manageable sub-problems, and related problem-solving skills are required
  • Creative mindset and curiosity to research and develop new solutions is required
  • A high level of written and spoken English is required
  • You may obtain further information from Professor Preben Mogensen, Department of Electronic Systems, phone: +4540503573, email: [email protected] , concerning the scientific aspects of the stipend.

    PhD stipends are allocated to individuals who hold a Master's degree. PhD stipends are normally for a period of 3 years. It is a prerequisite for allocation of the stipend that the candidate will be enrolled as a PhD student at the Technical Doctoral School of IT and Design in accordance with the regulations of Ministerial Order No. 1039 of August 27, 2013 on the PhD Programme at the Universities and Certain Higher Artistic Educational Institutions. According to the Ministerial Order, the progress of the PhD student shall be assessed at regular points in time.
    Shortlisting will be applied. This means that subsequent to the deadline for applications the head of department supported by the chair of the assessment committee will select candidates for assessment. All applicants will be informed whether they will be assessed or not.
    For further information about stipends and salary as well as practical issues concerning the application procedure contact Ms. Lisbeth Diinhoff , The Doctoral School at The Technical Faculty of IT and Design, email: [email protected] , phone: +45 9940 9589.
