“…The other one is a solution how to deliver these services, named Carrier Ethernet Transport (CET). Carrier Ethernet, e.g., Provider Backbone Bridge -Traffic Engineering (PBB-TE) is supposed to provide carrier -grade transport solution and leverage the economies of scale of traditional Ethernet [67]. It is defined in IEEE 802.1Qay-2009 standard.…”

Abstract-Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which can address a number of challenges the operators face while trying to support growing end-user's needs. The main idea behind C-RAN is to pool the Baseband Units (BBUs) from multiple base stations into centralized BBU Pool for statistical multiplexing gain, while shifting the burden to the high-speed wireline transmission of In-phase and Quadrature (IQ) data. C-RAN enables energy efficient network operation and possible cost savings on baseband resources. Furthermore, it improves network capacity by performing load balancing and cooperative processing of signals originating from several base stations. This article surveys the state-of-the-art literature on C-RAN. It can serve as a starting point for anyone willing to understand C-RAN architecture and advance the research on C-RAN.

“…This distance constraint results in the requirement of huge infrastructure support, like access points and backhaul links, in order to achieve a small distance reuse factor. Also, trying to achieve such a small reuse factor causes the so-called "backhaul challenge" [4]. One proposed solution to the above challenges is to use RF-backscattering [5], [6].…”

Abstract-Visible light communication (VLC) backscatter has been proposed as a wireless access option for Internet of Things (IoT). However, the throughput of the state-of-the-art VLC backscatter is limited by simple single-carrier pulsed modulation scheme, such as on-off keying (OOK). In this paper, a novel pixelated VLC backscatter is proposed and implemented to overcome the channel capacity limitation. In particular, multiple smaller VLC backscatters, switching on or off, are integrated to generate multi-level signals, which enables the usage of more advanced modulation schemes than OOK. Based on experimental results, rate adaptation at different communication distances can be employed to enhance the achievable data rate. Compared to OOK, the data rate can be tripled when 8-PAM is used at 2 meters. In general, n-fold throughput enhancement is realized by utilizing n smaller VLC backscatters while incurring negligible additional energy using the same device space as that of a single large backscatter.

“…Thus, the project envisages that the small cell network functions related to the user/data plane will remain distributed [18], while the control plane functions will be disaggregated from the RAN and hosted at the Main DC by using Commercial-of-the-Self (COTS) hardware. Although the design of such a centralized Software Defined-RAN (cSD-RAN) controller is a challenging task, since also real-time feedback of radio conditions should be taken into account, the distributed and network-integrated cloud inherited by SESAME so far is adequate for hosting controllers based on spatial segmentation, so this aspect can accelerate research results achieved to date.…”

Abstract. The 5G ESSENCE project's context is based on the concept of Edge Cloud Computing and Small Cell-as-a-Service (SCaaS) -as both have been previously identified in the SESAME 5G-PPP project of phase 1-and further "promotes" their role and/or influences within the related 5G vertical markets. 5G ESSENCE's core innovation is focused upon the development/provision of a highly flexible and scalable platform, offering benefits to the involved market actors. The present work identifies a variety of challenges to be fulfilled by the 5G ESSENCE, in the scope of an enhanced architectural framework. The proposed technical approach exploits the profits of the centralization of Small Cell functions as scale grows through an edge cloud environment, based on a two-tier architecture with the first distributed tier being for offering low latency services and the second centralized tier being for the provision of high processing power for computing-intensive network applications. This permits decoupling the control and user planes of the Radio Access Network (RAN) and achieving the advantages of Cloud-RAN without the enormous fronthaul latency restrictions. The use of end-to-end network slicing mechanisms allows for sharing the related infrastructure among multiple operators/vertical industries and customizing its capabilities on a per-tenant basis, creating a neutral host market and reducing operational costs.
