T1 – Tutorial Proposal: Energy-Neutral System-Level Analysis and Optimization of 5G Wireless Networks
The Internet of Things (IoT) will connect billions of devices by 2020. Such systems suppose batteries and/or energy harvesting from the environment, which also bets for very low energy devices. In order to enable IoT service capabilities, 5G wireless networks will need to bring a drastic energy efficiency improvement and will need to develop energy harvesting capabilities. This energy chase will cover low-energy devices and network elements, and will rely on the availability of renewable energy sources, dedicated power sources, as well as the possibility of harvesting energy directly from the radio waves that are primarily used for data transmission. This leads to a new design space, where the availability of energy is not deterministic anymore but may depend on environmental factors, the interference may not necessarily be harmful as it may be a natural source electromagnetic-based power to be used for replenishing the batteries of low-energy devices, and the intended signals may be exploited for both data transmission and energy harvesting. This paradigm-shift introduces a new concept in the design of 5G wireless networks: energy neutrality. Energy-neutral networks are systems that not only make an efficient use of the available energy, but, more importantly, that operate in a complete self-powered fashion. The present tutorial provides the audience with a complete survey of the potential benefits, research challenges, implementation efforts and application of technologies and protocols for achieving energy-neutrality, as well as the mathematical tools for their modeling, analysis and optimization. This tutorial is unique of its kind, as it tackles both system-level modeling and optimization aspects, which are usually treated independently. Special focus will be put on two methodologies for enabling the system-level modeling and the system-level and distributed optimization of energy-neutral 5G wireless networks: stochastic geometry and fractional programming. In the proposed tutorial, we illustrate how several candidate transmission technologies, communication protocols, and network architectures for 5G can be modeled, studied, optimized, and compared for their energy-neutral operation.
T2 – Simultaneous Energy and Information Transmission
This tutorial aims to familiarize the attendees with the new communication paradigm of simultaneous energy and information transmission (SEIT) in wireless networks. The tutorial is divided into four parts. In the first part, the relevance of SEIT is highlighted as a powerful technique to ensure a more efficient energy utilization in future “green†communication systems, e.g, 5G networks, small cells, Wi-Fi networks, sensor networks and ad hoc networks. In the second part, particular attention is paid to existing signal processing and communication techniques for implementing SEIT in wireless networks. In the third part, strong emphasis is put on the fundamental limits of SEIT using basic notions from information theory. Point-to-point and multi-user scenarios are studied and the key aspects of the energy-information trade-off are studied in both centralized networks, e.g, cellular networks and decentralized networks, e.g., sensor networks and ad hoc networks. In the latter, basic notions of game theory are studied to model the stable operating points of these networks. In the final part, practical aspects are tackled putting an emphasis on the main future challenges of SEIT in the context of 5G. For instance, front-end architectures allowing both energy harvesting and information decoding are studied. At the same time, aspects regarding in-band and out-band energy transmission as well as co-located and non-colocated receivers and energy harvesters are discussed.
T3 – Tutorial: Full-Duplex Techniques for Future Wireless Networks
In-band full-duplex (FD) technology, by which devices transmit and receive simultaneously on the same frequency band, has attracted a lot of research attention lately. Since FD radios can potentially double the spectral efficiency, they are a promising technology for 5G and future wireless networks. However, FD radios suffer from severe self-interference (SI), as well as extra cross-directional coupling between simultaneous uplink and downlink operation which further degrades the overall network performance. To this end, many research groups around the world have proposed new transceiver designs, implemented advanced FD prototypes and have shown that SI can be mitigated almost down to the noise floor, or even below in some cases. All these accomplishments show the feasibility of FD and its applicability for future wireless networks. Despite these fundamental results and achievements, there are still many challenges and open problems to resolve about FD operation. In order to achieve the full potential of FD transmission, it is necessary to cope with the self-interference and develop new mechanisms and efficient protocols.
T4 – Group oriented Communications in the 5G Era: Fundamentals, Applications and Novel Solutions for Performance Enhancement
Group-oriented services (broadcast, multicast, etc.) represent an effective solution to simultaneously convey data to a group of terminals through point-to-multipoint (PtM) communications. These services are able to improve capacity and spectrum efficiency in cellular systems which are crucial for the development of 5G networks, as highlighted, for instance, in recent METIS and 5GNOW European research projects. In the vision of future 5G systems where a massive growth of connected devices is expected, group-oriented services are expected to play a fundamental role. In this context, video transmission is considered as the “killer†human- and group-oriented application. However, high quality video transmission is a bandwidth-hungry application with stringent requirements in terms of jitter and data rate. A further key development trend towards the 5G era is the wide diffusion of low-power devices and a fast network densification to support the deployment of the Internet of Things (IoT). In this field, machine-type communications (MTC) push towards the design of effective solutions to deliver small amount of data simultaneously to a very large (and unpredictable) number of MTC/IoT devices. Group-oriented communications in the MTC/IoT environment require low latency and low overhead procedures in order to save battery resources. Based on these considerations, the ecosystem of 5G group-oriented services is expected to be really heterogeneous and requiring network flexibility according to the different service requirements. Research and industrial organizations are, therefore, being very active in the definition of well performing solutions to best handle this kind of traffic in cellular environments where the limited radio resources and the dissimilar channel quality experienced by users/devices are challenging aspects.
T5 – Tutorial proposal for European Wireless 2016 Challenges and solutions for networking in the millimeterÂwave band
The tutorial will highlight some of the challenges of and possible approaches for networking in the millimeter-wave (mm-wave) band. Communication at such high frequencies brings unique challenges, primarily due the high signal attenuation, which can only be overcome by the use of highly directional antennas. On the one hand side, this results in much less interference compared to omni-directional communication at lower frequencies, allowing for a high degree of spatial reuse and potentially simpler Medium Access Control Protocols (MAC) and interference management mechanisms. On the other hand, high directionality may cause deafness due to beam misalignments, whereas channels may appear and disappear over very short time intervals and cause sudden communication blockages, in particular for mobile devices. The tutorial specifically focuses on networking aspects of the MAC layer and above. It starts by an overview of mm-wave communication aspects and characteristics, and then delves into the most important network and protocol design aspects, ranging from beam-training and medium access to the impact on transport protocols and efficient network architectures.
