A group of 16 leading players in the field of telecommunications are joining forces to advance the development of a new air interface below 6 GHz for 5G networks. The “FANTASTIC-5G” (Flexible Air iNTerfAce for Scalable service delivery wiThin wIreless Communication networks of the 5th Generation) project focuses on boosting capacity, increasing flexibility and improving the energy efficiency of the next generation of mobile networks.
The aim of the two-year (2015-2017) FANTASTIC-5G project is to develop a new multi-service air interface that operates below 6 GHz frequency for 5G networks, and is:
The project supports the following use cases:
50 Mbps everywhere (MBB). This use case is representative for the scenario where high data rate in wide area coverage is required, for multiple services like Internet access, file downloading and video streaming.
High speed train (MBB+V2X). This use case is representative for the scenario where people use high quality mobile Internet not only in stationary or low-mobility scenarios, but also at higher speed (e.g. up to a range of 350-500 km/h) while using terrestrial transportation.
Sensor networks (MMC). This use case is representative for the scenario where small sensors and actuators, for example mounted onto stationary or movable objects, enable a wide range of applications related to monitoring, alerting or actuating. Typically, these devices need to transmit data only occasionally, e.g. minutes, hours, or weeks. The net payload for such applications is typically small, in the order of 20 to 125 bytes per message or even more in some special cases, and the latency requirements are often moderate, in the range of a few seconds.
Tactile Internet (MCC). This use case is representative for the scenario where a system is used by humans to wirelessly control real and virtual objects, and to accurately transmit the equivalent of human touch using the bits and bytes of data networks [ITU08.2014]. Tactile interaction typically requires a tactile control signal and audio and/or visual feedback.
Automatic traffic control / driving (MCC+V2X). This use case is representative for the scenario where advanced safety applications are used to mitigate and avoid road accidents, to improve traffic efficiency, and to support the mobility of emergency vehicles.
Broadcast like services: Local, Regional, National (BMS). This use case is representative for the scenario where systems for efficient distribution of information from one source to many destinations are used.
Dense urban society below 6GHz (MBB). This use case is representative for the scenario where a high number of users per km2 are requiring applications such as multimedia streaming with high demand in terms of traffic in urban outdoor and indoor environments.

The exponential growth in mobile data traffic, anticipated to reach a 1000 fold increase over the next decade, together with the large diversity of applications ranging from low bit-rate and low power machine-to-machine (M2M) applications to highly interactive and high resolution entertainment applications, impose to significantly reconsider a number of distinct technical requirements on hardware (HW) and software (SW) platforms, on top of which all mobile communication-related functionalities are implemented and executed. Among the most prominent requirements, the following must be highlighted: the further improvement of quality of experience (e.g., capacity, latency, resilience) and the energy efficiency, as well as the scalability, modularity, and reconfigurability when multiple Radio Access Technologies (RAT) are considered. To achieve these requirements, highly reconfigurable HW platforms and HW-agnostic SW platforms are needed.
The overall objective of Flex5Gware is to deliver highly reconfigurable HW platforms together with HW-agnostic SW platforms targeting both network elements and devices and taking into account increased capacity, reduced energy footprint, as well as scalability and modularity, to enable a smooth transition from 4G mobile wireless systems to 5G. In order to fulfil the above overall objective, Flex5Gware addresses the following specific objectives:
In Flex5Gware, three use case families have been identified, which combined, capture fundamental aspects of the 5G system:
For each use case family, use cases have been selected as a means to validate the project's Proof-of-Concepts (PoCs) within a context of 5G:
In the context of Flex5Gware, WINGS develops a platform that identifies and proactively/reactively responds to a Dynamic Hotspot situation through the dynamic reconfiguration of 5G HW/SW systems, taking advantage of Smart City monitoring services. This platform consists of the following software modules:
WINGS prospects/ exploitation
WINGS pursues products in the areas of smart wireless access including 5G systems, device management, IoT-cloud-embedded systems based services, and SW networks management. Its main competence is the attribution of networks and devices with management intelligence. To that respect, WINGS traditionally delivers software-intensive services and products, and has also started collaborations which include also the development of hardware. Therefore, WINGS puts in the core of its activities developments that rely on software and hardware co-design and integration for the benefit of a number of vertical application areas. In this respect, the involvement in Flex5Gware will help WINGS, leveraging on its background, to design and develop intelligent solutions for building flexible and cost-effective SW platforms that can exploit the HW versatility and reconfigurability.
The advanced 5G network infrastructure needs to be highly flexible in order to meet identified but dynamic, as well as unforeseen diverse requirements imposed by new cutting-edge applications, i.e., augmented reality, connected cars, tactile Internet, to name three main ones. Dynamic reconfiguration of future 5G HW/SW systems is the answer to this challenge, as it allows system's adaptation to the very demanding and changing contexts of operation, while guaranteeing Quality of Service (QoS) and Quality of Experience (QoE). The driver of WINGS contribution to Flex5Gware is a context-aware, dynamic and cognitive HW/SW partitioning mechanism for 5G network elements and devices. The mechanism generates and exploits knowledge (e.g. prediction of a hotspot) derived by network and sensor measurements and decides upon the HW or SW execution of functions (e.g. LTE, 3GPP based PHY/MAC functions), in order to fulfill and maintain the application goals. This solution leads to high flexibility, configurability, performance and energy efficiency.
The achievement above will enhance the management/control solutions portfolio of WINGS. WINGS will also expand its activities in the direction of developing certain of its intelligence, directly in HW. This will give further exploitable competences. Moreover, there will be effort focused on scalable management solutions that will enable the optimal deployment of novel sensor based applications in a 5G context. This area will also enhance the current activities of WINGS in IoT/Cloud areas.

SPEED-5G investigates in two and a half years starting from summer 2015, indoor and outdoor scenarios where capacity demands are the highest, but also where the eDSA will be the most effective at exploiting co-operation across technologies and bands including licensed, lightly-licensed and un-licensed bands.
The objective of SPEED-5G (quality of Service Provision and capacity Expansion through Extended-DSA for 5G) is to research and develop technologies that address the well-known challenges of predicted growth in mobile connections and traffic volume. A major challenge is the cost of meeting the objective, in terms of both infrastructure and deployment. SPEED-5G proposes the notion of eDSA (extended DSA), which is resource management with three degrees of freedom: densification, rationalized traffic allocation over heterogeneous wireless technologies, and better load balancing across available spectrum.
Massive IoT communications. Compared to the previous generations of networks, the Internet of Things (IoT) will have a major role in the service-compound supported by the forthcoming 5G networks. As pointed out by numerous reports and white papers (e.g. NGMN’s “Massive Internet of Things” use case or METIS’ “ubiquitous things communicating” scenario), one of the main objectives of 5G is a seamless integration of IoT at the early stage of the network architecture design.
Broadband wireless. The use case focuses on a mixture of domestic, enterprise and public access outdoor and indoor environments located in a densely populated urban area, such as a block of apartments, a square with shops and a recreation park. In this use case, a massive deployment of small cells is put in place to provide a uniform broadband experience to the users demanding high data rate and limited latency for the provisioning of applications such as high resolution multimedia streaming, gaming, video calling, and cloud services. Moreover, pedestrian users moving from indoor to outdoor environments (and vice versa), need to be supported.
WINGS ICT Solutions members' experience is exploited for the following objectives of the project:
Exploitation plans include the development of solutions which can support centralized and distributed channel selection in heterogeneous environments with learning enhancements as well. Such environments can be characterized by the dense deployment of cells and co-existence of licensed, unlicensed and 3.5GHz bands.

Investigating the potentials of Experiment-based Validation of Control Channels for Cognitive Radio Systems (EVOLVE). WINGS joined the CREW consortium as an Open Call partner in order to proceed to certain experimentation activities.
The aim of EVOLVE was to exploit various components and facilities of the overall CREW testbed in order to conduct realistic experiments for assessing and validating the performance of Control Channels for Cognitive Radio Systems (CC-CRS) in various scenarios. For this purpose, EVOLVE aimed to exploit developed CC-CRS components and interfaces and integrate them into the CREW testbed. Specifically, for various Cognitive Radio Systems (CRS) operation scenarios the exchange of corresponding messages over CC-CRS interfaces and CREW testbed facilities was monitored, so as to record performance indicators such as the total number of received and sent bytes, the signalling data bytes of every message that is sent or received, the time required for the exchange of information etc.
Regarding the obtained benefits, the user can achieve sufficient throughput and delay even when 5 hops are needed to communicate with the AP, due to the proximity of the devices. In addition, the operator can reduce its operating expenditure due to the fact that the devices can exploit their neighbours in order to maintain their QoS and there is no need for deployment of more infrastructure nodes. Finally, it should be noted that the developed solution takes into account the overhead of the signalling load. Therefore, in our experiment with 20 terminals the signalling load was around 2 Mbps.
The figure that follows shows an indicative topology of w.iLab-t testbed which was used for the experimentation. In the experimentation static and mobile nodes (robot) are considered for the evaluation.
UNIQUE will evolve, implement and experiment with a unified utility-based framework based on both QoS (network-centric) and QoE (user-centric) features and parameters, which allows to enhance, formulate and improve various advanced network operations in mobile broadband (MBB) infrastructures.
UNIQUE targets at two key runs of experiments and respective software extensions, depicting the operation and benefit of the proposed utility-based framework.
WINGS/INCELLIGENT will deliver the web-based application and work on the design of the extensions
WINGS/INCELLIGENT will implement the selection and multilink extensions required for running and evaluating the QoE-based experiments.
