- Reference Scenarios and Key Performance Indicators for 5G Ultra-dense NetworksPublication . Campos, Luís Miguel; Ribeiro, Luís; Karydis, Ioannis; Karagiannis, Stelios; Pedro, Dário; Martins, Jorge; Marques, Carlos; Armada, Ana García; Perez Leal, Raquel; López-Morales, Manuel José; Velez, Fernando J.; Sebastião, Pedro; Ramos, AndersonThe so-called 5G will revolutionize the way we live, and work. In order to demonstrate the profound changes, we can expect to experience within the next 5 to 10 years, we present use cases for the planned research within the TeamUp5G project. Some use cases are strongly linked to the network layer and aim at developing solutions capable of optimizing the main promising benefits of 5G: extremely low latency and extremely high bandwidth (e.g., handle video streams, traffic congestion, user profiles), in the most efficient way possible. Other use cases focus on commercial applications that make use of middleware applications to enhance their performance. The latter fall into two main areas: real-time virtual reality and live video streaming, which are extremely demanding in terms of latency and bandwidth to provide an acceptable QoE/QoS to multiple users. The use cases presented are built assuming that 5G is essential for their support with appropriate QoE/QoS. Key performance indicators and their range of variation are also identified.
- TeamUp5G: A Multidisciplinary Approach to Training and Research on New RAN Techniques for 5G Ultra Dense Mobile NetworksPublication . Pérez Leal, Raquel; Velez, Fernando J.; Campos, Luis Miguel; García Armada, AnaThis paper presents a summary of the main research directions being followed in TeamUp5G European Training Network, teaming up a new generation of researchers and entrepreneurs ready to address complex engineering problems and innovation to work both at university and industry in the 5G field. This project is focused on new radio access network (RAN) techniques for 5G, considering ultra-dense mobile networks as a key ingredient of the actual mobile networks and their evolution. Research covers a wide spread of topics from physical layer and medium access control to applications, looking at spectrum sharing and energy efficiency as important features.
- Inovação no Desenvolvimento do Curso Online Acessível a Todos (MOOC) sobre “Redes Ultra-densas 5G e sua Evolução”Publication . Lopez-Morales, Manuel J.; Urquiza, David; Gonzalez-Morin, Diego; Nidhi, Nidhi; Khan, Bahram; Kooshki, Farinaz; Al-Sakkaf, Ahmed; Leyva, Leonardo; Farkhari, Hamed; Medda, Daniele; Seitanidis, Ilias-Nektarios; Abu-Sabah, Ayman; Viana, Joseanne; Cumino, Pedro; Gil-Jimenez, Victor P.; Garcia, Maria J. Fernandez-Getino; Morales-Cespedes, Máximo; García Armada, Ana; Velez, Fernando J.Muitos dos novos dispositivos de comunicações móveis serão aparelhos que alimentam e monitorizam as nossas casas, infraestruturas urbanas e transportes. Controlar drones a milhares de quilómetros de distância, realizar cirurgias remotas ou estar imerso em vídeo com latência reduzida transformará certamente o acesso às tecnologias de informação e comunicação digitais. Estes são alguns dos aspetos que tornarão a quinta geração das comunicações móveis (5G) uma revolução, um impulso para a economia, e o foco de todos os intervenientes atuais na área das telecomunicações. Com este intuito, o planeamento e a crescente densidade de implantação destas novas redes introduzem novos desafios de otimização. Que elementos serão adicionados em relação às gerações anteriores? Baseados num Curso Online Acessível a Todos (MOOC) anteriormente desenvolvido na UC3M (UC3M Staff, 2022), o MOOC sobre redes ultra-densas 5G e sua evolução foi elaborado pelos investigadores da Marie Skłodowska-Curie Actions (MSCA) ITN/ETN Europeia (teamUp5G Reserachers, 2022), denominada TeamUp5G (Teamup5G, 2022; Pérez Leal et al., 2020) e apresenta as tecnologias mais importantes que suportam comunicações móveis 5G, com ênfase no aumento de capacidade e redução de energia, que facilitam o desenvolvimento de redes com pequenas células. Os conteúdos abrangem aspectos desde tecnologias de comunicação até casos de utilização, prototipagem e o futuro próximo, sem esquecer questões como a gestão de interferência, eficiência energética ou gestão de espectro. O objetivo do MOOC (TeamUp5G, 2022) é preencher a lacuna na aprendizagem ao nível dos estudos de graduação e pós-graduação, em conteúdos relacionados com tecnologias 5G emergentes e suas aplicações, incluindo a 6G futura. O público-alvo envolve engenheiros, investigadores, profissionais e estudantes. O artigo descreve o conteúdo e os resultados de aprendizagem do MOOC, as principais tarefas e recursos envolvidos na sua criação, as contribuições conjuntas do setor académico e não académico, e aspectos como a conformidade relativamente aos direitos de autor, garantia de qualidade, testes e detalhes sobre comunicação e inscrição, seguidos da discussão das lições extraídas.
- Massive Online Open Course (MOOC) on ‘Ultra-dense Networks for 5G and its Evolution’Publication . Lopez-Morales, Manuel J.; Urquiza, David; Gonzalez-Morin, Diego; Nidhi, Nidhi; Khan, Bahram; Kooshki, Farinaz; Al-Sakkaf, Ahmed; Leyva, Leonardo; Farkhari, Hamed; Medda, Daniele; Seitanidis, Ilias-Nektarios; Abu-Sabah, Ayman; Viana, Joseanne; Cumino, Pedro; Gil-Jimenez, Victor P.; Garcia, Maria J. Fernandez-Getino; Morales-Cespedes, Máximo; García Armada, Ana; Velez, Fernando J.Many of the new mobile communication devices will be things that power and monitor our homes, city infrastructure and transport. Controlling drones thousands of miles away, performing remote surgeries or being immersed in video with no latency will also be a huge game changer. Those are some ofthe few things that make the fifth generation (5G) a revolution expected to be a thrust to the economy. To that end, the design and density of deployment of new networks is also changing becoming more dense, what introduces new challenges into play. What else will it add to previous generations? The MOOC about Ultra-dense networks for 5G and its evolution has been prepared by the researchers of an European MSCA ITN, named TeamUp5G, and introduces the most important technologies that support 5G mobile communications, with an emphasis on increasing capacity and reducing power. The content spans from aspects of communication technologies to use cases, prototyping and the future ahead, not forgetting issues like interference man agement, energy efficiency or spectrum management. The aim of the MOOC is to fill the gap in graduation and post-graduation learning on content related to emerging 5G technologies and its applications, including the future 6G. The target audience involves engineers, researchers, practitioners and students. This paper describes the content and the learning outcomes of the MOOC, the main tasks and resources involved in its creation, the joint contributions from the academic and non-academic sector, and aspects like copyright compliance, quality assurance, testing and details on communication and enrollment, followed by the discussion of the lessons learned.
- MOOC as a Way of Dissemination, Training and Learning of Telecommunication EngineeringPublication . Gil Jiménez, Víctor P.; Urquiza Villalonga, David Alejandro; López Morales, Manuel José; Medda, Daniele; Seitianitis, Ilias-Nektarios; Al-Sakkaf, Ahmed Gaafar; Khan, Bahram; García, M. Julia Fernández-Getino; García Armada, Ana; Chatzimisios, Periklis; Iossifides, Athanasios; Morales Céspedes, Máximo; Velez, FernandoIn this chapter, the use of massive open online courses (MOOCs) for the dissemination, training capabilities and learning of telecommunication engineering is described taking as example the successful MOOC ‘Ultra- Dense Networks for 5G and its Evolution’ developed under the European innovative training network (ITN) TeamUp5G. MOOCs are usually understood as a way of teaching or learning for massive potential students. Indeed, this is the main goal of any MOOC. However, we also propose its use for training and dissemination. The ITN TeamUp5G is a training network for 15 PhD students of seven different institutions (universities and companies) where the students make research on different interconnected topics for the common goal of Ultra dense networks for 5G. At the same time they researched, they prepared a MOOC to disseminate their most recent advances and their challenges. For the MOOC, they needed to collect their thoughts, organizse their knowledge and establish a common vision of the whole system. The cooperative work, the cross-related meetings and, the preparation of all the materials for the MOOC were very interesting and useful in their training process. The whole experience of designing and creating the MOOC is described in detail along with the challenges and lessons learned.
