Dynamically Reconfigurable Optical-Wireless Backhaul/Fronthaul with Cognitive Control Plane for Small Cells and Cloud-RANs


5G-XHaul aims at building up an ambitious converged optical and wireless network solution that relies on a flexible infrastructure able to support backhaul and fronthaul networks. This is required to tackle the current and future challenges the Radio Access Network (RAN) imposes. 5G-XHaul will provide an efficient, reconfigurable, modular and highly scalable platform to support RAN processing depending on different architectural solutions, network elements and devices.


To support these novel concepts, 5G-XHaul will develop:

  1. Dynamically programmable, high capacity, low latency, point-to-multipoint (P2MP) mm-Wave transceivers, cooperating with Sub-6 GHz systems;
  2. A Time Shared Optical Network offering elastic and fine granular bandwidth allocation, cooperating with advanced passive optical networks;
  3. A software-defined cognitive control plane, able to forecast traffic demand in time and space, and the ability to reconfigure network components.

IHP's Contribution

IHP will investigate the requirements and specifications of the mm-Wave circuits to be leveraged along the project, and will be involved in their physical deployment. IHP will design and fabricate mm-Wave beam steering chipsets as well as mm-Wave up- and down-converters. IHP will also perform module integration with mm-Wave antenna, test and calibration. To achieve P2MP connectivity, fast beam training algorithms as well as methods for beam tracking will be researched. IHP will contribute with accurate RAN PHY localisation algorithms, as well as the interfaces to deliver the information obtained by these algorithms to the 5G-XHaul control plane. IHP will also work on the definition of spatio-temporal demand prediction models based on the information/data provided by the network.
