The evolution towards a fully connected society in the 5G era and beyond (5G&B) involves increasing complex communications and unprecedented network densification. In response to this increase in intensity of network traffic from heterogeneous terminals, the 5G&B RUNNER project is focused on designing, analysing and evaluating a series of radio technologies in ultra-dense networks to meet the requirements of service capacity and quality, distributed intelligence and flexibility that are needed for 5G&B systems. Fulfilling these tasks has required the use of tools that are based on advanced signal processing, information theory, communications theory, and multi-objective distributed optimisation.
The work programme includes the development of algorithms of physical layer and medium access control, such as low-consumption multi-antenna transceivers with high spectral efficiency, multiuser transmission schemes in the visible spectrum and machine-type communications. In addition, network optimisation algorithms have been designed, including traffic engineering algorithms for wireless backhaul and the allocation of resources in the short-and long-term in ultra-dense networks. All algorithms have been developed using a rigorous mathematical procedure and validated using extensive simulations.
The 5G&B Runner project has received funding of 181,500 euros from the Ministry of Science, Innovation and Universities, and it lasted 4 years (December 2016 to September 2020). It was coordinated by the Signal Processing and Communications (SPCOM) research at the UPC.
