Tutorial T1:Waveforms and Multiple Access for 5G Mobile Communication
Date & Time: November 6th 2016, 9.30 a.m.-1.00 p.m.
Speakers: Prof. Kiran Kumar Kuchi, IIT Hyderabad.

Abstract:
The emerging 5G mobile communications standard is expected support multiple services such as eMBB (enhanced mobile broadband), ultra-low latency communication and massive machine-type-communication (mMTC) services using a common frame structure. The system will be designed such that multiple services employing distinct numerologies (e.g. different subcarrier widths, cyclic prefix duration etc.) would coexist in the same band. The offered services may use different waveforms, different multiple access methods etc. This type of coexistence not only improves bandwidth utilization but also reduces the operational cost. There is industry wide consensus that 5G would adopt a modified version of OFDM technology. The standard is expected to adopt filtering or windowing methods to reduce the out-of-band emissions and to enable multi-service coexistence. Furthermore, mMTC and millimeter wave transmission requires a waveform with low peak-to-average power ratio (PAPR) for efficient uplink operation. A new low PAPR modulation called Generalized Precoded OFDM (GPO) has emerged as a candidate for the uplink. In this tutorial, we discuss the above mentioned technologies followed by an overview of massive MIMO and millimeter wave transmission techniques that are being considered in the 3GPP 5G study phase.



Tutorial T2: From Network Science to Network Engineering: Understanding and building dynamic networks
Date & Time: November 6th 2016, 9.30 a.m.-1.00 p.m.
Speaker: Prof. Pavel Loskot, Swansea University, UK.

Abstract:
Network Science is an immensely interesting research area with many applications. It was originated by physicists, however, as it rapidly emerged since 2000, it was taken over mainly by computer scientists. On the other hand, the methods and tools of telecommunications engineering were developed completely independently from those that are used in Network Science. It was not only until several years ago that the importance of networks started to be recognized more broadly by the IEEE community. We expect that Network Science methods will become especially important to deal with growing complexity of emerging telecommunication networks such as the Internet of Things and the heterogeneous 5G networks with multi-scale and flexible coverage.

The aim of this tutorial is to make telecommunication researchers aware of the main findings and important results in Network Science. The focus is on dynamic networks where networks can be considered as generic objects providing certain utility and services such as delivery of information or physical objects. I will discuss how network topology and architecture can be represented by the corresponding mathematical models pointing out that these models are not unique but application and often available measurement data driven. In many scenarios, the graph models can be treated as specific structured signals or systems, so conventional signal processing methods such as statistical inferences and optimization techniques can be employed.

Network Science traditionally assumed information cascades and epidemic spreading as the main applications whereas search and navigating over networks are two important applications in computing. In telecommunications and other man-made networks, our main concern is network monitoring and management to use the network resources efficiently. Moreover, many real-world networks experience random events that often disrupt the normal network operation and the offered services. All networks that provide some utility experience the demand increases over time, so the engineers have to consider network planning and dimensioning to respond to the growing demands. This also includes finding and removing the bottlenecks to improve or just to maintain the network efficiency in delivering services. One of the most frequently used strategies is offloading traffic (information or physical objects) via the underlying or overlaying networks. In some scenarios, network robustness may be crucial to offer the services with minimum disruptions due to unpredictable events, for example, due to a sudden peak in the service demand.



Tutorial T3:Open Air Interface (OAI) for Experimentation in 5G
Date & Time:November 6th 2016, 2.00-5.30 p.m.
Speaker: Prof. Bheemarjuna Reddy Tamma (IIT Hyderabad, India),  Prof. Kiran Kuchi (IIT Hyderabad, India) and Dr.Rohit Gupta (Eurecom)

Abstract:
Open Air Interface (OAI) is a flexible platform towards building an open cellular ecosystem which offers low-cost 4G/5G deployment and experimentations. The platform currently offers an open-source software based implementation of full protocol stacks of LTE system components i.e., OAI soft UE, OAI soft eNB, OAI soft EPC (MME and S+P-GW).  OAI is written in standard C for several real-time Linux variants optimized for Intel x86 and ARM processors. It is designed to be agnostic to the underlying hardware RF boards. Officially, it supports EURECOM EXMIMO2 and USRP X-series/B-series boards. OAI can be used to deploy customized LTE eNB and EPC on one or more PCs and connecting to them commercial LTE UEs to study different network configurations and setups.  One of the main objectives of OAI is rapid prototyping of 3GPP compliant and non-compliant use cases as well as new concepts towards 5G systems ranging from M2M/IoT and SDN/NFV to cloud-RAN and massive MIMO.

Part I of this tutorial covers OAI’s high level software architecture, LTE RAN/EPC implantation details as well as information regarding tools used in the development of the protocol stack. Then Part II provides some methodologies used for proof-of-concept design (simulation, testing and deployment) as well as some use cases of OAI experimental 5G research for realization of Cloud-RAN and LTE-Wi-Fi Aggregation.

Tutorial T4:Architectures of Next Generation Wireless Networks
Date & Time:November 6th 2016, 2.00-5.30 p.m.
Speaker: Prof. Pascal Lorenz, University of Haute Alsace, France.

Abstract:

Emerging Internet Quality of Service (QoS) mechanisms are expected to enable wide spread use of real time services such as VoIP and videoconferencing. Quality of experience (QoE) is a subjective measure of a customer’s experiences with a service. The “best effort” Internet delivery cannot be used for the new multimedia applications. New technologies and new standards are necessary to offer QoS/QoE for these multimedia applications. Therefore new communication architectures integrate mechanisms allowing guaranteed services as well as high rate communications.
The emerging Internet architectures, differentiated services and integrated services, do not consider user mobility. QoS mechanisms enforce a differentiated sharing of bandwidth among services and users. Thus, there must be mechanisms available to identify traffic flows with different parameters, and to make it possible to charge the users based on requested quality. The integration of fixed and mobile wireless access into IP networks presents a cost effective and efficient way to provide seamless end-to-end connectivity andubiquitous access in a market where the demand for mobile Internet services has grown rapidly and predicted to generate billions of dollars in revenue.
This tutorial covers to the issues of provisioning in heterogeneous networks and Internet access over future wireless networks. It discusses the characteristics of the Internet, mobility and provisioning in wireless and mobile IP networks. This tutorial also covers routing, security, baseline architecture of the inter-networking protocols, end to end traffic management issues and QoS for Mobile/Ubiquitous/Pervasive Computing users.
