What will you be doing?

The development of 5G mobile network technology towards the efficient and effective support of a variety of services is primarily driven by the requirements of so-called ‘verticals’, e.g. Automotive/Smart Mobility, eHealth, Media & Entertainment and Factory of the Future (FoF). Each of the verticals offers diverse services/applications with specific characteristics and various technical and performance requirements. For example, the FoF vertical requires 5G network technology to support both Ultra-Reliable Low-Latency Communication (URLLC) services and non-URLLC services. FoF services are generally bursty in nature, e.g. short requests for information, transfer of sensor readings or control commands.

To meet the stringent requirements for URLLC services, user equipment (UE) relaying can be used to increase the transmission reliability. In a relaying scenario, UEs are not only connected to a cellular base station, but potentially also to other nearby UEs, using different radio access technologies (RATs). These nearby UEs act as relay nodes, that increase the reliability by relaying the same data to the base station. Additionally, the coverage of the network is improved, since UEs without a cellular connection can still reach the base station with the help of one or more relay nodes.

The objective of the graduation project is to investigate the potential of UE relaying for increased reliability in different scenarios (outdoor, indoor, factories). Specifically, the following steps are foreseen:
  • To become acquainted with the current UE relaying testbed of TNO. It consists of Pycom boards that support five different RATs, and for each of these RATs some parameter about the quality of the link is available.
  • To design one or more RAT selection and routing algorithms that improve the reliability of all UEs. Options include a distributed algorithm, where every UE uses only its local information, and a centralized one. The algorithm should make a choice between using only one RAT or multiple RATs, where in the latter case the data is duplicated, and hence more radio resources are used. Additionally, historical knowledge about the link qualities might also be used.
  • To implement the above in a basic system-level simulator, which can be used to quickly assess, compare and improve the algorithms.
  • To implement the algorithms on the Pycom boards and do extensive tests in a variety of environments. The algorithms will probably behave differently in every environment, since the dynamics are completely different.
  • Key outcome of the project includes conclusions and recommendations regarding the involved reliability/capacity/latency trade-offs, the attainable reliability gains in different scenarios and what algorithm(s) is/are most suitable to achieve these gains under different circumstances.

What do we require of you?

  • You are a graduate student pursuing a Master's degree, preferably in the direction of Electrical Engineering or Computer Science.
  • You have affinity with / interest in mobile networks, computer simulations and programming experience.
  • You have an enterprising, flexible and cooperative nature.
  • You are also communicative, creative and innovative.

The duration of the internship is seven to nine months.
