This chapter contains a brief overview of the overall architecture of an NR radio-access network and the associated core network, followed by descriptions of the radio-access network user-plane and control-plane protocols.

6.1 Overall System Architecture

In parallel to the work on the NR (New Radio) radio-access technology in 3GPP, the overall system architectures ...
