“…Hence, recent research studies aim at designing an integrated FH and BH network architecture under the control of an SDN Transport Orchestrator [24,25]. Furthermore, the envisaged deployment scenarios for 5G networks usually entail a variety of transport technologies that, ideally, should be managed homogeneously [26]. Hence, the general 5G RAN scenario requires an end-to-end orchestration of resources across multidomain multitechnology transport networks for offering network slicing and vertical services.…”

The fifth generation (5G) of cellular networks promises to be a major step in the evolution of wireless technology. 5G is planned to be used in a very broad set of application scenarios. These scenarios have strict heterogeneous requirements that will be accomplished by enhancements on the radio access network and a collection of innovative wireless technologies. Softwarization technologies, such as Software-Defined Networking (SDN) and Network Function Virtualization (NFV), will play a key role in integrating these different technologies. Network slicing emerges as a cost-efficient solution for the implementation of the diverse 5G requirements and verticals. The 5G radio access and core networks will be based on a SDN/NFV infrastructure, which will be able to orchestrate the resources and control the network in order to efficiently and flexibly and with scalability provide network services. In this paper, we present the up-to-date status of the software-defined 5G radio access and core networks and a broad range of future research challenges on the orchestration and control aspects.

“…In this way, all antennas connected to the same PON share the same DWDM channel. Benefits of this network architecture solution include the coexistence of different traffic natures and policies, low congestion at the access nodes, compatibility with legacy systems and industrial temperature ranges, and provides similar performances to standard dual fiber networks [18], [19].…”

The current constant growth in mobile networks' traffic demands caused by the popularisation of cloud and streaming services on personal devices, requires architectural changes so as to fulfil all new 5G mobile network requirements. Cloud access radio network (C-RAN) architecture in combination with the massive deployment of small cell antenna sites have recently been proposed as a promising solution but will be demanding for high capacity mobile fronthaul links. An efficient way for performing that connectivity is to make use of the dense wavelength multiplexing passive optical network (DWDM-PON) infrastructure. In this context, OFDM has been extensively explored as a potential candidate. Nevertheless, the main drawback of OFDM is its high out-of-band radiation. In order to overcome that drawback, new 5G multicarrier waveforms (FBMC, UFMC and GFDM) have recently been proposed. In this paper, we experimentally assess and compare 10Gbps 32-QAM-OFDM/FBMC/UFMC/GFDM system performance for high-layer split ultra-DWDM-PON-based fronthaul using a radio-over-fiber technique. The performance has been done in terms of spectral efficiency, peak-to-average power ratio, spectral density and receiver sensitivity. In particular, intensity-modulation with direct-detection and quasi-coherent-detection have been considered. In order to improve the multicarrier system energy efficiency, the effect of using a hard clipping technique over transmitted signals is also studied. Finally, we evaluated the crosstalk interference between two adjacent channels of the same modulation scheme, as a function of their electrical frequency span for downlink application.Index Terms-Filter-bank based multi-carrier, fronthaul, generalised frequency division multiplexing, orthogonal frequency division multiplexing, radio-over-fiber, universal filtered multicarrier.

“…One of the biggest challenges recently faced by telecom providers is to meet demanding requirements of data traffic capacity in ultra-dense urban areas like metropolitan areas and hot-spot areas such as football stadiums with thousands of users highly concentrated in a small geographical region, where the footprint is critical and new network architectures should be considered. Accordingly, the cloud (also called centralized) radio access network (C-RAN) fronthaul architecture [9]- [11] can potentially overcome the capacity and coverage drawbacks as well as latency constraints of today's limited technologies, and consequently reduce the footprint. This new concept of fronthaul architecture, C-RAN fronthaul, provides several benefits not only in terms of technical specifications like capacity and network coverage, but also by increasing the network flexibility and wisely controlling operational costs.…”
