Strategic goal: 5G and beyond radio access solutions

The requirements for future wireless connectivity vary by application, but will include data rates ranging from very-low-rate sensor data to very-high-quality video content delivery, low delay/latency requirements, low energy consumption, and high reliability. All these require different radio access solutions which furthermore depend on the frequency band and available bandwidth used. Our major goal is to investigate and conduct experiments into how the increasing carrier frequency and system bandwidth together with increasing heterogeneity of the required services will impact overall radio access network design. This research question is fundamental to defining design principles where the trade-off between network density, capacity and implementation cost is well understood as a function of frequency, bandwidth and user mobility. Practical design solutions will include future waveforms, air interfaces and transceiver algorithms capable of supporting the transmission. Target of the research is in disruptive 10X technology components for 5G and beyond radio access solutions.

University of Oulu and Nokia Bell Labs has several ongoing research projects in radio access technologies, including both bilateral and Tekes funded projects. 

Example projects:

  • High5 (Tekes and industry co-funded project) – Investigate how the increasing carrier frequency and system bandwidth will impact radio access technologies.
  • Bilateral project on 5G air interface solutions for vehicles.
