The present document is an introduction to the 3GPP TS 38.46x series of technical specifications that define the E1 interface. The E1 interface provides means for interconnecting a gNB‑CU‑CP and a gNB‑CU‑UP of a gNB‑CU within an NG‑RAN, or for interconnecting a gNB‑CU‑CP and a gNB‑CU‑UP of an en‑gNB within an E‑UTRAN.
