Future Radio Access
The requirements for 5G 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 5G waveforms, air interfaces and transceiver algorithms capable of supporting the transmission.
