MASTEAM Talk: Application-aware User-centric Programmable Architectures for 5G multi-tenant networks

The Master's degree in Applied Telecommunications and Engineering Management (MASTEAM) organizes a weekly series of activities (talks, technical visits, discussion pannels) that complement the academic activities with real-world experiences from companies, research centres and institutions in the main topics of the master: Internet of Things. Smart Cities, 5G mobile communications, Software-Defined Networking (SDN) and Radio (SDR), cloud computing, augmented reality and audiovisual services, among others.

May 31st, 17:30h (duration 1h), Building C4, Classroom 021B, EETAC, Campus Castelldefels UPC. How to arrive.

We will have two short talks from researchers from the Horizon 2020 5GAuRA project.

Title: Joint optimization of access and backhaul in 5G networks

Abstract: 5G network is expected to serve huge traffic, with high data rates and very low latency. To achieve this high capacity, densification of cells in the network seems to be an effective solution. Densely deployed cells and large amount of devices will create Ultra Dense Network (UDN), which also imposes straighten requirement to the backhaul network. Besides, due to the different use cases of future Access Points (AP), it is not possible to rely only on wired backhaul. Although, wireless backhaul solutions are already popular but limited to line-of-sight solutions. However, in 5G network, higher frequency bands will be employed by both the access and backhaul network to achieve the expected capacity. Hence, access and backhaul cannot be considered as separate entities anymore, rather, the line between them has to be blurred to ensure the efficient use of precious resources. This talk validates the necessity of joint optimization of access and backhaul. Moreover, different approaches and adaptable techniques for joint optimization are discussed.

Bio: Rakibul Islam Rony is from Bangladesh, and he was born in 1986. He received his B.Sc. Eng degree from Islamic University of Technology (IUT), Bangladesh in 2008 and completed his M.Sc (Tech) inCommunications Engineering – Radio Communications from Aalto University, Espoo, Finland in January, 2014. At the beginning of his career, he worked as RF Engineer II in Huawei Technologies Bangladesh ltd for two years (2009 – 2011). He started his master studies in November 2011 and worked as Research Assistant in Aalto University to carry out his master’s thesis. After completing his M.Sc, he worked as Senior Lecturer in the department of Electrical and Electronic Engineering (EEE) in Primeasia University, Bangladesh for two years (2014 – 2016). From June 2016 till October 2016 he served as Assistant Professor in Eastern University, EEE department. In November 2016, he started working as Marie Curie Early Stage Researcher (ESR) for H2020 project 5GAuRA, in the Network Engineering Department of Universitat Politecnica de Catalunya (UPC), BarcelonaTECH. His research interest is focused on 5G, wireless communications, wireless technologies, next generation wireless techniques, resource management and sharing, SDN.

Speaker: Akshay Jain
Title: Mobility management mechanisms in current and 5G networks

Abstract: The amount of data that will flow through the wired/wireless networks will grow 10-12 times by 2021. The growth in the number of users is following a similar exponential trend, and hence, in order to cater to the ever-burgeoning requirements, a new generation of wireless technology, i.e., 5G networks is current being researched, developed and standardized. With a network that is projected to be dense, heterogeneous and diverse, mobility becomes challenging. And so, in this talk we will discuss the existing/legacy as well as the proposed mobility management mechanisms, with the aim of understanding their advantages/disadvantages in current and 5G networks. We will also discuss the various challenges that await the design and development of mobility management mechanisms for 5G networks.

Bio: Akshay Jain received his B.Tech degree in Electronics and Communications engineering from S.V. National Institute of Technology, Surat, India in 2013. He also received his MS degree in Electrical and Computer Engineering from University of Florida, USA in 2015. Akshay, during the period of 2011-2013, was also the recipient of the prestigious Kishore Vaigyanik Protsahan Yojana (KVPY) fellowship awarded by the Dept. of Science and Technology, Govt. of India. Further, from July 2015 to September 2016, he was also the lead Communication systems engineer at a startup called Queen B Robotics in San Francisco, California, USA. Currently he is pursuing his Ph.D. degree in 5G communications at the Network Engineering department at Universitat Politècnica de Catalunya, Barcelona, Spain. He is also a Marie Curie Early Stage Researcher at the European Union Funded 5G-AURA project. Akshay’s current research interests include 5G, wireless networks, mobility management, optimization theory, numerical methods, machine learning, radars and array processing.
