5G NR (New Radio) is a new Radio Access Technology (RAT) developed by 3GPP for the 5G mobile networks. In this course you will have an in-depth understanding about 5G Radio Access Network (RAN) based upon the 3rd Generation Partnership Project (3GPP) standard and specifications. The 5G New Radio standards developed by 3GPP is intended to significantly improve the performance, flexibility, scalability and efficiency of mobile networks. In this way 5G was designed to be able to ensure the optimum use of the available spectrum, whether it is licensed, shared or unlicensed, and achieve this across a wide variety of spectrum bands. 5G New Radio is able to provide high bandwidth communication for the transmission of streaming services as well as low latency services.This course is targeted for:Telecom professionals/ engineersTelecom studentsNetworking students Course Contents:Section 1: Introduction Main Components of a 5G Network Architecture Next Generation NodeB (gNB) PDU (Protocol Data Unit) Sessions 5G Use Cases Mapped to Difference Usage Scenarios 5G NR Frequency Bands Most Popular 5G BandsSection 2: 5G Radio (Wireless) Access Technology (RAT) 5G Wireless Access Technology Basics of Orthogonal Frequency Division Multiplexing (OFDM) OFDM in Its Simplest Form OFDM IN Practice (Simplified Model) Mutipath Environment And Cyclic Prefix 5G Flexible Numerology and Frame Structure 5G Resource Block (RB) and Resource Element (RE) 5G FDD TDD Modes-SUL and SDL Frequency Bands Slot Formats and Slot Format Indicators (SFI) in 5G 5G NR self Contained Slots Mini-Slots in 5G NR Modulation in 5G Adaptive Modulation and Coding in 5G Modulation and the Coding Schemes (MCS) in 5G Why Lower Numerology-SCS for Larger Cell Size SCS Vs Cell Size Advantages of TDD Deployment 5G Frequency Bands in FR1 and FR2Section 3:Massive MIMO And Beam Forming in 5G Introduction to MIMO, Beamforming and Massive MIMO 5G NR Transmission Chain Types of Beamforming-Analog Beamforming Digital Beamforming Hybrid Beamforming 5G NR Active Antenna System (AAS) 8T8R & 64T64R Configurations in 5G Active Antenna System (AAS) Comparison of Antenna Sizes in Sub 6 GHz & mmWave Virtualized Antenna Representation Active Antenna Unit (AAU) in 5G Antenna Configurations for Different RF Planning Scenarios Single Panel & Multi-panel Antennas Grid of Beams (GoB) Antenna Port Vs Physical Antenna Quasi Co-Located (QCL) Ports DL MIMO Characteristics in Sub 6GHZ DL MIMO Characteristics in mmWave Why DL-MU-MIMO is Limited to Maximum 16 Layers?
