The growing demand in indoor small cell networks has given rise to the concept of micro-operators (MOs) for local service delivery. We model and analyze a spectrum sharing system involving such MOs where a buyer MO buys multiple licensed subbands provided by the regulator. All small cell base stations (SBSs) owned by a buyer MO can utilize multiple licensed subbands. Once the buyer MO obtain subbands, it allows other MOs to share these subbands. A deterministic model in which the location of the SBSs are known can lead to unwieldy problem formulation, when the number of SBSs is large. As such, we adopt a stochastic geometric model of the SBS deployment instead of a deterministic model. Assuming that the locations of the SBSs can be modeled as a homogeneous Poisson point process, we find the downlink signal-to-interference-plus-noise ratio (SINR) coverage probability and average data rate for a typical user (UE) served by the buyer MO in a spectrum sharing environment. In order to satisfy the QoS constraint, we provide a greedy algorithm to find how many licensed subbands and which subband the buyer MO should purchase from the regulator. We also derive the coverage probability of the buyer MO for interference limited system.

We are the last global eco-system which still advances its entire technology family in generations, having started as a 1G-niche and now entering the transformational era of 5G. The typical 10-years innovation cycles between generations, the “Gs”, worked well in the past but are unfortunately not adequate for the future. Based on some past trends, the aim of this paper is to develop a technology and innovation roadmap for the mobile ecosystem. Notably, required technology disruptions to the cellular infrastructure are discussed as well as much-needed changes in the overall innovation landscape suggested, which would enable a massive shift from selling the cost of connectivity to co-creating value in ubiquitous connectivity.

Software-defined networking is at the root of future 5G transport network design. Among others, it allows for automated network reconfiguration and network slicing support. In this paper we present an OpenFlow-based implementation of a control plane area in the transport network architecture envisioned by the 5G-XHaul project. We analyze the implementation of the slicing mechanism at the network edge. Furthermore, we propose a simple low-overhead fast proactive failover scheme for recovering from single link failures, without the delays and packet drops associated with reaching a remote controller entity.

The concept of network slicing opens the possibilities to address the complex requirements of multi-tenancy in 5G. To this end, SDN/NFV can act as technology enabler. This paper presents a centralised and dynamic approach for creating and provisioning network slices for virtual network operators' consumption to offer services to their end customers, focusing on an SDN wireless backhaul use case. We demonstrate our approach for dynamic end-to-end slice and service provisioning in a testbed.

Ultra-reliable V2V communications with extreme transmission rate probably constitute the most ambitious use case of the fifth generation mobile. At present, both the scientific community and the standardization bodies are addressing the design of the technologies that will make it possible, although there is no unanimity in which technologies to incorporate. This paper approaches this topic from the work developed in the METIS-II project, describing the use case, the technology enablers and some details of the evaluation of these techniques in realistic scenarios. Results show that, for a baseline system, carrier bandwidths needed to fulfil the requirements are between 30 and 100 MHz, depending on the scenario. Nevertheless, results show potential to reduce the needed bandwidth to a range between 20 and 50 MHz by incorporating additional technology enablers to the studied baseline system.

In this paper we investigate, through experimental measurements, a propagation model of the visible light. The scope is to come up with a fine tuned propagation model which also accounts for reflection from the optical bench. The experiments were conducted in the European Laboratory of Non Linear Spectroscopy (LENS). The proposed propagation model can be used to evaluate the performance of visible light communications, in particular in the context of indoor applications.

Vehicle-to-Everything (V2X) communication holds the promise for improving road safety and reducing road accidents by enabling reliable and low latency services for vehicles. Vehicles are among the fastest growing type of connected devices. Therefore, there is a need for V2X communication, i.e., passing of information from Vehicle-to-Vehicle (V2V) or Vehicle-to-Infrastructure (V2I) and vice versa. In this paper, we focus on both V2I and V2V communication in a multi-lane freeway scenario, where coverage is provided by the Long Term Evolution Advanced (LTE-A) road side unit (RSU) network. Here, we propose a mechanism to offload vehicles with low signal-to-interference-plus-noise ratio (SINR) to be served by other vehicles, which have much higher quality link to the RSU. Furthermore, we analyze the improvements in the probabilities of achieving target throughputs and the performance is assessed through extensive system-level simulations. Results show that the proposed solution offloads low quality V2I links to stronger V2V links, and further increases successful transmission probability from 93% to 99.4%.

New waveforms are considered by the fifth generation (5G) of cellular networks to exploit the underutilized fragmented spectrum. FBMC is one possibility as it provides better adjacent channel leakage. This paper brings a first estimate of silicon area for FBMC in comparison to OFDM assuming a CMOS 65nm technology. The paper concludes that the silicon area overhead introduced by much more complex waveforms is deemed acceptable.

This paper derives an optimal source and a close-to-optimal relay precoding structures for minimising the energy consumption of cooperative multiple-input-multiple-output (MIMO) amplify-and-forward (AF) systems, i.e. when relay and direct links are jointly considered. Even though the optimisation problem at hand is generally non-convex, we prove that the energy consumption optimisation function is unimodal when either the source or relay precoding matrix is known. Then, an iterative process is utilised to jointly optimise the source and relay precoding matrices. Simulation results confirm the benefit, in terms of energy consumption, of our novel approach for cooperative MIMO-AF systems in comparison with approaches optimising either the direct or relay link only, with a 20–30% improvement gain in favorable channel conditions.

The fifth generation of mobile networks (5G) and the internet of Things (IoT) impose very stringent requirements to the optical transport networks. On the one hand, high flexibility, ultra-low latency and high capacity, in order to support the forecasted 1000x growth in mobile data traffic with latencies below millisecond. On the other hand, massive edge and core cloud infrastructure integrated with the transport network to dynamically deploy NFV, MEC, and IoT analytics. This paper presents ADRENALINTE testbed, an SDN/NFV packet/optical transport network and edge/core cloud platform for end-to-end 5G and IoT services.
