The CU receives 5GC N1 signaling. The CU converts a first portion of the 5GNR RRC signaling into LTE RRC signaling and converts a first portion of the 5GC N1 signaling into LTE Non-Access Signaling (NAS). The CU transfers LTE Physical Layer High (PHY-H) signaling to an LTE Physical Layer Low (PHY-L) in an LTE Distributed Unit (DU). The CU transfers 5GNR PHY-H signaling to an 5GNR PHY-L in a 5GNR DU. The LTE DU receives the LTE PHY-H signaling and transfers the LTE RRC signaling and the LTE NAS signaling to LTE User Equipment (UE). The 5GNR DU receives the 5GNR PHY-H signaling and transfers the second portion of the 5GNR RRC signaling and the second portion of the 5GC N1 signaling to a 5GNR UE."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Physical layer split in a multi-radio access technology (RAT) central unit (CU)","description":"A Central Unit (CU) receives Fifth Generation Core (5GC) N2 signaling and generates Fifth Generation New Radio (5GNR) RRC signaling.
