In this paper, we investigate the energy efficiency performance of optimal proactive scheduling strategies in the context of ultra-dense networks. The network consists of a superposition of homogeneous Poisson point process, whereas the users requests follow a space-time homogeneous point process. The objective is to define the optimal transmission powers at any time, that allows to completely serve...
This paper presents the vision of 5G-MiEdge, a research project leveraging the benefits of merging MEC and mmWave technologies. Based on that vision, the most relevant use cases and services for the forthcoming Tokyo 2020 Olympics are proposed. The focus is on showing how integrating MEC and mmWave into the 5G network architecture can offer a much more effective system. That is achieved by means of...
This paper describes the first available 5G testbeds as designed by 5G CHAMPION, a collaborative research project undertaken by over twenty consortium members and targeting the provision of 5G services at the 2018 Winter Olympics in Korea. In order to provide 5G services such as augmented reality (AR), virtual reality (VR), high quality, interactive multi-player video games, the testbeds shall fulfill...
Mobile Edge Computing (MEC) plays a key role in the 5G roadmap, as a way to bring information technology (IT) services closer to the mobile users by empowering radio access points with additional functionalities, like caching or computation offloading capabilities. At the physical layer, some of the key technologies enabling very low latency mobile services are dense deployment of radio access points,...
The 5G CHAMPION Consortium will provide the first fully integrated and operational 5G prototype in 2018 - this effort is a major leap ahead compared to existing punctual technology trials, such as, e.g., Proof-of-Concept platforms focusing on mmWave communication in specific bands, etc. This paper describes the overall set-up including a synergetic combination of technologies such as beamforming based...
In 5G mobile networks, computing and communication converge into a single concept. This convergence leads to introduction of Mobile Edge Computing, where computing resources are distributed at the edge of mobile network, i.e., in base stations. This approach significantly reduces delay for computation of tasks offloaded from users' devices to cloud and reduces load of backhaul. However, due to users'...
Edge computing through local mobile cloud computing platforms is a key enabler for coping with the ever increasing data traffic requirements. A key enabler for this technology is the awaited ultra-dense deployment of radio access points for future 5G networks. Local cloud platforms allow maintaining a scalable network design by jointly managing local radio and computational resources. The Fog, a platform...
Introduction of Internet of Things and Machine Type Communication to future mobile networks will cause significant increase in the number of connected devices. At the same time, the connected devices can change traffic patterns as frequent transmission of small volumes of data is expected from sensors and machines. Transmission of such data is very inefficient due to redundancy of signaling information...
This paper proposes a strategy, described via a process, which can help collaborative research projects impact standards and engage with regulatory bodies. The process is being successfully used by a running EU-funded project that is taken as a concrete example of how to link in a proper way innovation and pre-development activities to standards. The proposed methodology has a general validity and...
Ultra-dense deployment of radio access points is a key enabler for future 5G networks. It allows the network to cope with the ever increasing mobile data traffic. In addition, these radio access points can serve as an infrastructure for a local mobile cloud computing platform referred to as fog computing. The fog is a capillary edge cloud that enables joint optimization of communication and computational...

Femto-cloud is a novel networking architecture that joins femtocells networks and computation offloading to the cloud in a single framework. This allows to form server farms of femtocell access points providing cloud services. However, femtocells cannot offer the same computation and storage capacities as traditional cloud servers. In the femto-cloud platform, femtocells cooperate together through...
To avoid call drops after handover due to unavailability of radio resources at a target handover cell, call admission control procedure reserves a specific amount of resources for users performing handover to this cell. If a high amount of resources is reserved, the available capacity for users served by the cell is lowered. Contrary, if a low amount of resources is booked for users entering the new...
Due to large numbers of interferers, in-band interference is a bottleneck that future wireless heterogeneous networks have to deal with. Recent advances in information theory have shown that interference does not have to be avoided or strongly limited, so that reliable transmissions can occur. In this paper, we propose a novel Radio Resource Management (RRM) approach, capable to exploit those recent...
