Étude, Planification et Dimensionnement de la 5G NR

Abstract

Aujourd'hui, le système de communications mobiles de quatrième génération (4G) ne peut pas répondre à certaines exigences particulières, notamment une densité de trafic élevée, un grand nombre de connexions et la mobilité. En outre, il a été prévu que les systèmes de communications mobiles de cinquième génération (5G)commencent à être commercialisés et déployés en 2018 pour de nouveaux services mobiles dans trois caractéristiques clés, à savoir, les communications ultra-fiables et à faible latence, haut débit mobile amélioré et les communications massives de type machine. Par conséquent, sur la base des recherches préliminaires pour la normalisation de la 5G par les leaders de l'industrie des télécommunications depuis 2012, l'Union internationale des télécommunications a identifié et annoncé la vision 5G et ses indicateurs de performance clés sur l'efficacité spectrale, l'efficacité énergétique, le débit de données de pointe, la densité du trafic, la connectivité des appareils, latence radio et fiabilité pour une réalisation plus complète et une meilleure fourniture de services. Dans ce contexte, notre projet dévoile cette nouvelle technologie ainsi que leurs objectifs et leurs étapes de normalisation par l'UIT et le 3GPP, la planification et le dimensionnement du réseau mobile 5G dans lequel nous avons cité une démonstration faite à l’aide du logiciel « Atoll ».

ملخص

في الوقت الحالي، لا يستطيع نظام الاتصالات المتنقلة من الجيل الرابع (4G)تلبية بعض المتطلبات الخاصة بما في ذلك كثافة حركة المرور العالية وعدد كبير جدًا من الاتصالات والتنقل العالي. بالإضافة إلى ذلك ،كان من المتوقع أن يبدأ تسويق أنظمة الاتصالات المحمولة من الجيل الخامس(5G)ونشرها في عام 2018 لخدمات الهاتف المحمول الجديدة في ثلاث ميزات رئيسية ، أي الاتصالات فائقة الموثوقية و الكمون المنخفض ، والنطاق العريض المتنقل المحسن ، والاتصالات الضخمة . لذلك بناءً على بحث أولي لتقييس(5G)بواسطة الاتصالات قادة الصناعة منذ عام 2012، حدد الاتحاد الدولي للاتصالات (ITU) وأعلن عن رؤية (5G)ومؤشرات الأداء الرئيسية بشأن كفاءة الطيف ، وكفاءة الطاقة ، وذروة إنتاجية البيانات ، وكثافة حركة المرور ، واتصال الأجهزة وزمن انتقال الراديو والموثوقية لتحقيق أكثر اكتمالاً وتوفير أفضل للخدمات. في هذا السياق، سيتم تنفيذ مشروعنا حيث نبدأ بعرض تقديمي كامل عن الأجيال السابقة، ثم نحدد جميع النقاط المهمة لهذه التكنولوجيا الجديدة بالإضافة إلى أهدافها وخطوات التقييس الخاصة بها من قبل الاتحاد الدولي للاتصالات و3GPP و التخطيط وحجم شبكة الهاتف المحمول (5G) باستخدام «أتول".

Abstract At present, the fourth generation (4G) mobile communications system is not able to satisfy some special requirements including high traffic density, high traffic volume density, high number of connections and high mobility. So, it is anticipated that the Fifth Generation (5G) mobile communication systems will start to be commercialized and deployed in 2018 for new mobile services in three key features, namely, enhanced Mobile Broadband, massive Machine Type Communications, and Ultra-Reliable and Low Latency Communications. Therefore, based on the preliminary research for 5G standardization by telecom industry leaders since 2012, the International Telecommunication Union has identified and announced the 5G vision and Key Performance Indicators on spectrum efficiency, energy efficiency, peak data rate, traffic density, device connectivity, radio latency and reliability for achieving more comprehensive and better service provisioning. It is in this context will take place our project that we begin with a complete presentation on the previous generations, we then define all the important points of this new technology as well as their objectives and their stages of standardization by the ITU and 3GPP, the planning and sizing of the 5G mobile network that we using "Atoll " .
