In this deep dive into the 5G NR (New Radio), we will review the 3 major use cases: enhanced mobile broadband access (eMBB), massive machine communications (mMTC), mission-Critical machine communications (URLLC) and the technology and the Release 15 technology that will make it possible.
Lesson 1 - An Introduction to 5G Technology
Introduces the fundamentals of 5G New Radio (known as NR) Release 15 (the first release) and how it applies to a variety of industry use cases. It covers the key features of 5G NR, such as carrier aggregation, millimeter wave (mmWave) frequencies, and beamforming.
Lesson 2 - New Radio Non-Standalone and Standalone Differences
Learn the differences between Non-Standalone (NSA) and Standalone (SA) 5G NR. NSA is a deployment option that allows 5G NR to be deployed alongside 4G LTE. SA is a deployment option that allows 5G NR to operate independently of 4G LTE.
Lesson 3 - Carrier Aggregation & Bandwidth Adaptation
Carrier aggregation, which is a technique that allows 5G NR to aggregate multiple carrier frequencies, is covered. This can be used to increase the overall bandwidth available for 5G NR users.
Lesson 4 - Numerology & Frame Structure
Discover the numerology and frame structure of 5G NR. Numerology refers to the number of subcarriers and symbols used in each frame. Frame structure refers to the way that the subcarriers and symbols are arranged in each frame.
Lesson 5 - Waveforms & Modulations
Waveforms and modulations used in 5G NR is covered. Waveforms are used to transmit data over the air. Modulations are used to encode data onto the waveforms.
Lesson 6 - Protocol Structures, Layers, Signals & Channels
Learn the protocol structures, layers, signals, and channels used in 5G NR. Protocol structures define how data is exchanged between different parts of the 5G NR network. Layers refer to the different functional blocks that make up the 5G NR protocol stack. Signals are used to carry data between different layers. Channels are the physical paths that data travels over in the 5G NR network.
Lesson 7 - Beams, Beamforming & Beam Management
Beams, beamforming, and beam management in 5G NR are discussed. Beams are used to focus the radio signal in a particular direction. Beamforming is a technique that uses multiple antennas to create beams. Beam management is used to control the beams in the 5G NR network.
