The technical, research and innovation activities in iCIRRUS were divided up into 4 main work packages:
WP2 formulated the key concepts on which the project built, defining the detailed system architecture from use-case scenarios, and taking these into a techno-economic analysis. WP3 and WP4 were the main research and innovation work packages, focussing on the requirements of the optical fronthaul in the intelligent C-RAN architecture (WP3) and the algorithms for the D2D communication, its interaction with the infrastructure and the use of the mobile cloud (WP4). These work packages fed information to WP5 for the demonstrator definition and including algorithms for the implementation. Specific hardware development, to be used in validation of key concepts, was carried out in WP5, which also organised a validation in network operators’ premises. All of WP3, WP4 and WP5 provided information back to WP2 for the techno-economic analysis.
In addition, to these work packages, WP1 was devoted to project management, and WP6 was devoted to the organisation of dissemination, standardisation, exploitation and communication activities. These work packages therefore interacted with all of the technical, research and innovation work packages.
