To meet the high throughput demands envisaged for 5G networks, with increased user densification and bandwidth-hungry applications, while at the same time reducing energy consumption, iCIRRUS proposes an intelligent Cloud-Radio Access Network (C-RAN) that brings together optical fibre technology, low-cost but highly flexible Ethernet networking, wireless resource management for device-to-device (D2D) communication (incl. the use of mm-wave spectrum) and the use of virtual mobiles in the cloud. The iCIRRUS C-RAN introduces the use of Ethernet in the fronthaul/midhaul (for radio signal transport), to minimise cost and make available pluggable and in-device monitoring, and intelligent processing to enable self-optimizing network functions which maximise both network resource utilisation and energy efficiency. To exemplify the attractiveness of the proposition, iCIRRUS focusses on D2D communication in the wireless domain, an important work area in current standardisation, where low latency is known to be a significant factor. The latency and jitter in the iCIRRUS Ethernet-based C-RAN will be an important focus of the research work in the project, with current 5G performance targets in mind; for D2D communications, the task will be to minimise control latency and overhead. A major obstacle for C-RANs is the bit-rate of the digitised radio signals that would be required for 5G of the order of 100 Gb/s and iCIRRUS will examine the architectural and technological questions surrounding this requirement. Wireless resource management will be investigated, together with mobile device caching and mm-wave D2D mesh networks, to reduce latency as well as load on the infrastructure. Finally, the intelligent network functions in ICIRRUS can interact with mobile cloud processing, and further offloads of infrastructure communications can be realised through virtualising mobiles in the cloud as clones, and performing communication tasks between clones.

Small Cells, Cloud-Radio Access Networks (C-RAN), Software Defined Networks (SDN) and Network Function Virtualization (NVF) are key enablers to address the demand for broadband connectivity with low cost and flexible implementations. Small Cells, in conjunction with C-RAN, SDN, NVF pose very stringent requirements on the transport network. Here flexible wireless solutions are required for dynamic backhaul and fronthaul architectures alongside very high capacity optical interconnects. However, there is no consensus on how both technologies can be most efficiently combined. 5G-XHaul proposes a converged optical and wireless network solution able to flexibly connect Small Cells to the core network. Exploiting user mobility, our solution allows the dynamic allocation of network resources to predicted and actual hotspots. To support these novel concepts, we will develop: 1) Dynamically programmable, high capacity, low latency, point-to-multipoint 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. The well balanced 5G-XHaul consortium of industrial and research partners with unique expertise and skills across the constituent domains of communication systems and networks will create impact through: a) Developing novel converged optical/wireless architectures and network management algorithms for mobile scenarios; b) Introduce advanced mm-Wave and optical transceivers and control functions; c) Support the development of international standards through technical and techno-economic contributions. 5G-XHaul technologies will be integrated in a city-wide testbed in Bristol (UK). This will uniquely support the evaluation of novel optical and wireless elements and end-to-end performance.

DIMENSION establishes a truly integrated electro-optical platform, extending the silicon (Bi)CMOS and silicon photonics platform with III-V photonic functionality. The III-V integration concept is fully CMOS compatible and offers fundamental advantages compared to state-of-the art integration approaches. After bonding and growing ultra-thin III-V structures onto the silicon front-end-of-line, the active optical functions are embedded into the back-end of line stack. This offers great opportunities for new innovative devices and functions at the chip-level but also for the assembly of such silicon devices. As processing takes place on silicon wafers, this project has the unique opportunity to bring the cost of integrated devices, with CMOS, photonic and III-V functionality, down to the cost of silicon volume manufacturing. Such a platform has the potential to allow Europe to take a leading position in the field of high functionality integrated photonics. Moreover, the project demonstrators adhere to standards such as IEEE802.3, 25G optical components and low-power electronics, thus opening a viable route towards ultra-low-cost high-performance optical transceivers for a new era of data centres and cloud systems. DIMENSION will realise three demonstrators: A short-reach transmitter for intra-datacenter operation addressing the 400 GbE-LR8 (IEEE 802.3bs) standard making use of an array of directly modulated lasers, pulse-amplitude-modulation (PAM4) techniques and 8 wavelength channels in the telecom O-band. A medium-reach transmitter for inter-datacenter applications beyond the 400 GbE-LR8 (IEEE 802.3bs) standard by providing a tuneable coherent transmitter for inter-datacenter and metro applications for link lengths in excess of 10km using a modulator integrated on the same chip. A novel laser directly grown on silicon photonics, operated at 25Gb/s in the telecom O-band demonstrating the significant cost-saving potential of the technologies pursued in DIMENSION.
