Tutorial #2

Rate Splitting for MIMO Wireless Networks: A Promising PHY-Layer Strategy for 5G

Bruno Clerckx and Hamdi Joudeh

Tutorial description

MIMO processing plays a central part towards the recent increase in spectral efficiencies of wireless networks. MIMO has grown beyond the original point-to-point channel and nowadays refers to a diverse range of centralized and distributed deployments. The fundamental bottleneck towards enormous spectral efficiencies in multiuser MIMO networks lies in a huge demand for accurate channel state information at the transmitter (CSIT). This has become increasingly difficult to satisfy due to the increasing number of antennas and access points in 5G networks relying on dense heterogeneous networks and transmitters equipped with a large number of antennas. CSIT inaccuracy results in a multi-user interference problem that is the primary bottleneck of MIMO wireless networks. Looking backward, the problem has been to strive to apply techniques designed for perfect CSIT to scenarios with imperfect CSIT. This tutorial departs from this conventional approach and introduces the audience to a promising strategy based on rate-splitting. Rate-splitting relies on the transmission of common messages (decoded by multiple users) and private messages (decoded by their corresponding users). This strategy is shown to provide significant benefits in terms of spectral efficiencies, reliability and CSI feedback overhead reduction over conventional strategies used in LTE-A and exclusively relying on private messages. The benefits of rate-splitting will be further demonstrated in a wide range of scenarios: multi-user MIMO, massive MIMO, multi-cell MIMO, overloaded systems, Non-Orthogonal Multiple Access (NOMA), multigroup multicast and caching. Open problems, impact on standard specifications and operational challenges will also be discussed.

Tutorial #3

Energy-Neutral System-Level Analysis and Optimization of 5G Wireless Networks

Alessio Zappone, Marco Di Renzo, and Eduard Jorswieck

Tutorial description

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.

Tutorial #5

Full-Duplex Techniques for 5G and Beyond

Hirley Alvesy and Taneli Riihonen

Tutorial description

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 severeself-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. The objective of this tutorial session is to present the state-of-the art of FD systems, discuss the research challenges ahead and lay out all the key applications within emerging and future wireless networks.

Tutorial #6

Fronthaul Compression for Cloud Radio Access Networks

Abdellatif Zaidi and Inaki Estella Aguerri

Tutorial description

Cloud radio access networks (CRAN) provide a new architecture for next-generation wireless cellular systems in which the baseband processing is migrated from the base stations (BSs) to a central processor (CP) in the "cloud". The BSs operate as simple radio units (RUs) and are connected to the CP via fronthaul links. The fronthaul links carry information about the baseband signals, in the form of quantized inphase and quadrature (IQ) samples. This CRAN architecture is generally seen as a possible means of enabling interference management at the geographical scale covered by the distributed radio units, through the allowed joint processing at the CP. Also, it has some other appreciable features, such as low cost deployment of BSs and exible network utilization.
Due to the large volumes of the quantized IQ signals, compression prior to transmission on the fron- thaul links is critical. Current solutions, which are the object of various standardization eforts, prescribe the use of conventional scalar quantizers for this purpose. However, with this approach, fronthaul links are known to impose an important bottleneck to the system performance. Therefore, more advanced forms of compression are needed and are receiving considerable interest. Multiterminal compression allows for the joint processing of the compressed IQ samples of diferent RUs at the CP. Speciacally, in the uplink, joint decompression enables the CP to leverage the correlation among the signals received by neighboring RUs through Wyner-Ziv coding. In the downlink, the joint compression allows the CP to correlate the quantization noises of the baseband signals transmitted by neighboring RUs, through multivariate compression. Multiterminal compression uses unstructured quantization codebooks that are designed indepen- dently of the channel codebooks used for transmission on the wireless channel. A conceptually diferent technique, which employs structured codebooks, leads to new strategies for the CRAN that are based on the framework of compute-and-forward. This tutorial is aimed at providing a survey of the work in the area of fronthaul compression with emphasis on advanced signal processing solutions, based on communication and information theoretic concepts. Speciacally, the main ideas that are brought to bear from network information theory are multiterminal compression and structured coding.
