This lesson covers 5th generation technique. It discusses the basic framework on which the 5G stands, that is the OFDM, and its modification, DFT spread OFDM. The lesson also explains the specifications of the 5th generation system, especially the frame format and how OFDM fits in. It introduces the term 'New Radio' (NR), which is the air interface for the 5th generation. The lesson also highlights the importance of backward and forward compatibility in the evolution of technology. It provides an overview of the 3GPP (3rd Generation Partnership Project) and its role in proposing the next generation system, the NR.

- The 5th generation system primarily uses OFDM.
- The term 'New Radio' (NR) is used to refer to the air interface for the 5th generation.
- The 3GPP unites several telecommunication standards development organizations and creates specifications for the next generation system.
- The evolution from one generation to another is a continuous process, not a sudden change.
- Backward and forward compatibility is crucial in the evolution of technology.
- The 5G technology is expected to meet the IMT-2020 requirements.
