NR Physical Layer: Overview
Abstract
5G New Radio is the first ever cellular technology to operate at millimeter-wave frequencies, support GHz of bandwidths, and utilize a massive number of antennas. NR will operate in the sub-1 GHz to 100 GHz carrier frequency range under different types of deployments to support various human-centric and machine-centric applications. The NR radio protocol has been developed and standardized in 3GPP since April 2016. The first release of NR (3GPP NR Release 15) was completed in June 2018. In this chapter, we provide an overview of the NR physical layer based on Release 15. The NR physical layer includes modulation schemes, waveforms, channel codes, multiantenna techniques, frame structure, duplexing ...
