T1: Heterogeneous Cellular Networks: Modeling, Analysis and Design using Stochastic Geometry
Presented by: Tony Q. S. Quek, Singapore University of Technology and Design; Marios Kountouris, Supélec, France
Room: Studio 1
With the increase in data traffic driven by a new generation of wireless devices, data is expected to overwhelm cellular network capacity in the future. Heterogeneous cellular networks are a comprehensive approach to provide high cellular network capacity by overlaying conventional macrocell cellular architecture with heterogeneous architectural features such as small cellular access points (picocells and femtocells), low-power fixed relays, and distributed antennas. Heterogeneous cellular networks are expected to achieve higher data rates and better coverage by exploiting spatial reuse, while retaining at the same time the seamless connectivity and mobility of cellular networks. Inspired by the attractive features and potential advantages of heterogeneous cellular networks, their development and deployment is gaining momentum in the wireless industry and research communities during the last few years. It has also attracted the attention of standardization bodies such as 3GPP LTE-Advanced. However, heterogeneous cellular networks also come with their own challenges, and there are significant technical issues that still need to be addressed for successful rollout and operation of these networks. One of the main challenges is interference management and this tutorial will present a stochastic-geometry based approach to understand such interference and better design heterogeneous cellular networks
The main objective of this tutorial is to introduce stochastic geometry to academic and industrial researchers, especially as an effective and suitable mathematical tool to better understand and design heterogeneous cellular networks. In addition, the tutorial will identify and discuss technical challenges and recent results related to the performance and the design of heterogeneous cellular networks.

T7: Cooperative Near-Capacity Wireless System Design
Presented by: Lajos Hanzo, School of Electronics and Computer Science, University of Southampton, UK
Room: Studio 2
This overview introduces the principles of cooperative communication, commencing with the introduction of the basic MIMO types having both co-located and distributed antenna elements and continues with a portrayal of cognitive radio aided cooperation, win-win cooperation, a glimpse of base-station cooperation, and so on.
To elaborate a little further, the limitations of MIMOs relying on co-located array-elements are highlighted and it is shown, how the single-antenna-aided cooperative mobiles may circumvent these limitations by forming MIMOs having distributed elements. This concept is also referred to as a Virtual Antenna Array (VAA). Then the corresponding amplify-forward and decode-forward protocols as well as their hybrids are studied. Channel coding has to be specifically designed for the VAAs in order to prevent avalanche-like error-propagation. Hence sophisticated three-stage-concatenated iterative channel coding schemes are proposed and it is argued that in the absence of accurate channel information at the relays the best way forward might be to use multiple-symbol differential detection. Indeed, it is rather unrealistic to expect that an altrustically relaying handset would also accurately estimate the source-relay channel for the sake of high-integrity coherent detection. EXIT-chart-aided designs are used for creating near-capacity solutions and a range of future research directions as well as open problems are stated.
- Cooperative Adaptive Modulation
- Successive Relaying Aided Near-Capacity Irregular Distributed Space-Time Coding
- Coherent versus Non-Coherent Detection
- Resource-Optimized Differentially Modulated Hybrid AF/DF Cooperation Dispensing with Channel Estimation
- Distributed Channel Coding
- Multiple Source Cooperation
- Synchronous versus Asynchronous Cooperative Systems
- Cognitive and win-win cooperation
Whilst this overview is ambitious in terms of providing a research-oriented outlook, potential attendees require only a modest background in wireless networking and communications. The mathematical contents are kept to a minimum and a conceptual approach if adopted. Postgraduate students, researchers and signal processing practitioners as well as managers looking for cross-pollination of their experince with other topics may find the coverage of the presentation beneficial. The participants will receive the set of slides as supporting material and they may find the detailed mathematical analysis in the books coauthored by the presenter.
This tutorial creates a bridge between classic MIMOs having co-located elements and distributed MIMOs. Furthermore, intrinsically amalgamates the channel coding and transmission schemes and reviews the pros and cons of coherent versus non-coherent cooperative transceivers.

T9: Beamforming in Multi-Cell Systems
Presented by: Jinho Choi, School of Information and Communications, Gwangju Inst. of Science & Tech. (GIST), Korea
Room: Studio 3
Beamforming has been studied to increase signal-to-noise ratio (SNR) or spatial multiplexing gain in wireless communication systems over the last two decades. In particular, multiple-input multiple-output (MIMO) systems, beamforming plays a crucial role in exploiting the tradeoff between multiplexing and diversity gains. In future wireless systems, the role of beamforming will be more important as large antenna arrays are to be employed at base stations. In this tutorial, we overview existing beamforming methods used for single-user and multi-user systems. Then, we present some recent advances of beamforming for more general systems such as multi-cell MIMO systems. Network and massive MIMO will also be presented.

T11: M2M Communications Within Future Communication Networks
Presented by: Konstantinos Dimou, Intel
Around 2020 some billions of devices are going to be connected. Everything benefiting from being connected will be connected. New and diverse Machine To Machine (M2M) applications are expected: from wearables, low cost monitoring sensors for agriculture purposes, health applications and to vehicle to vehicle communications as well as for smart grid and for high end computing machines and robots exchange very high data rates with latency requirements in the order of a millisecond. These new applications and their traffic exhibit new requirements in terms of data rates, delay, energy consumption which are different from the requirements imposed by human centric communications. Moreover, it is anticipated that devices of various capabilities are going to co-exist within the same radio access networks. In addition, this unprecedented high amount of connected devices sets a stringent requirement for reduced signaling overhead. A key question to be answered by system designers and researchers is how to evolve current wireless networks so as to accommodate devices of various capabilities and with many different traffic characteristics. This tutorial aims at providing the basis for how data rate, energy consumption, device cost, latency and signaling overhead requirements are driving the design of radio interface, e.g. radio signal, time frame structure, as well as multiple-access mode. Suitability of current 4G wireless systems for meeting these goals is discussed. Evolution directions towards 5G wireless networks are proposed.
Understanding of the requirements in terms of data rates, latency, energy consumption, signaling overhead and cost for Machine to Machine Communications.
Understanding the level of suitability of 4G wireless systems, e.g. 3GPP LTE Advanced, to meet these requirements.
Ability to make radio interface design choices based on the various M2M QoS requirements and devices characteristics. Integration strategies of various technologies.
- - Understanding the fundamental requirements of M2M QoS requirements: data rates, latency, signaling overhead, energy consumption, cost.
- - Suitability of 3GPP LTE Advanced and IEEE 802.11 based systems so as to meet M2M QoS requirements.
- - Design principles towards a 5G system meeting the M2M QoS requirements
- - Radio frame structure: pilot design, radio frame duration, control channel considering latency and energy requirements
- - Multiple access design considering the signaling overhead requirement and the very high number of connections
- - Integration of various radio access networks. Migration strategies.
- - Pros and Cons of various options
The tutorial is addressed to system designers and researchers working towards 5G system design.
Up to now tutorials on M2M tend to address one M2M scenario and mainly the low cost sensors communications, addressed partly by the work done within 3GPP in the context of Machine Type Communications (MTC). There are very few tutorials addressing QoS requirements of various M2M applications and providing propsals for an overall system design solution.
