3GPP has not designed 5G in isolation. Indeed, LTE and LTE-Advanced are used as the baseline. Enhancements to existing features have been made, and new capabilities are added to design 5G. If you know LTE and LTE-Advanced, this chapter can be a good refresher. Of course, if you are new to LTE or LTE-Advanced, consider this chapter as a prerequisite for 5G! If you are unsure about studying this chapter, take the podcast and video quizzes and Concept-o-Meter test and see if you may benefit from a refresher.
