Physical Layer Processing Supporting Technologies

In NR, the main downlink physical layer data carrying channel is called the Physical Downlink Shared Channel (PDSCH), and the main uplink physical layer data carrying channel is called the Physical Uplink Shared Channel (PUSCH). The overall data processing in these channels is largely similar. Most of the key technologies required in this processing have already been covered in prior chapters of this text. The purpose of this chapter is to cover those necessary technologies not yet covered, some simple but key to the processing chain, and to the expand discussion on selected ones previously covered. Thus, by the end of this chapter, we will have covered the key technologies necessary to comprehend in some detail 5G NR physical layer processing of the main data carrying channels which will be addressed in Chap. 10 .
