Multiantenna wireless architectures for next-generation wireless systems – MANTUA

The aim is to develop advanced antenna systems and solutions for 5G and beyond 5G wireless communication networks.

Objectives
  • Determine the functionalities to be performed at each node of heterogeneous wireless networks for optimal performance in terms of capacity, coverage, latency, energy efficiency, and reliability
  • Develop centralised/decentralised cooperative MIMO techniques approaching the optimal performance identified above
  • Demonstrate the identified solutions on a hardware testbed

Motivation
Next-generation mobile communication systems will need to support a massive increase in capacity, to meet the traffic demands by 2020 and beyond. They will also need to support new use cases with end-to-end latencies down to 1 ms, for interactive applications and ultra-responsive mobile cloud-services. In addition, these services will need to be provided seamlessly to the users, also when mobile, with similar energy consumption as today’s networks.

Cooperative massive multi-node multiple-input multiple-output (MIMO) techniques, node densification, and the use of new spectrum bands in the mmwave range are the key technological enablers to implement this vision. However, limited research has been performed so far on mm-wave mobile access and non-line-of-sight wireless backhaul/fronthaul networks.

Today’s state-of-the-art mobile network deployments rely on stand-alone radioaccess technologies (RATs). In contrast, future networks are expected to leverage a close interworking between different RATs to, for example, enable network assisted mm-wave nodes. This will be possible only through tight network coordination. Suitable architectures, where the processing is optimally split among the various layers of this dense heterogeneous network, need to be explored.
