PDCCH implementation based on 5G NR system and comparision with LTE PDCCH

Abstract

The 5G NR system starts with Release 15 and includes Release 16. The NR system has added physical channels identical to LTE and physical channels for duplication in high-speed and high-frequency environments. In this paper, the characteristics of PDCCH physical channel in LTE and NR system are compared and the implementation of NR PDCCH is discussed.
