The 5G NR radio access network is comprised of these protocol entities: Service data adaptation protocol (SDAP) Packet data convergence protocol (PDCP) Radio link control (RLC) Medium access control (MAC)
Read moreWhat is 5G physical layer?
PHY layer sits at the bottom of the 5G NR protocol stack, interfacing to MAC sublayer higher up via transport channels . It provides its services to MAC and is configured by RRC . PHY supports downlink ( gNB -to- UE ), uplink ( UE -to- gNB ) and sidelink ( UE -to- UE ) communications.5 Nis 2021

This page covers 5G Protocol Stack i.e. layer 1,layer 2 and layer 3 . The 5G layer-1 is PHYSICAL Layer. The 5G layer-2 include MAC, RLC and PDCP.
Read moreHow is 5G architecture different from 4G?
4G uses 20 MHz channels, while 5G will use 100 MHz to 800 MHz channels . Cell density. Small cell technology enables 5G to provide more cell density and enhance network capacity.
