In plain words
TS 38.420 introduces the TSG RAN TS 38.42x series of Technical Specifications that define the Xn interface: "an introduction to the TSG RAN TS 38.42x series of Technical Specifications that define the Xn interface". Xn is an interface for interconnecting two NG-RAN nodes within the NG-RAN architecture. The document therefore provides an introduction to the series and describes the interface's role between NG-RAN nodes.

How this page was made
The facts box and the tables come straight from the 3GPP specification archive and CR database as indexed by 3GPP Scout. An AI model (GPT-6 Luna) wrote the paragraph and named the source of each sentence. Code checked every quote word for word against the stored source text and every number against the cited source. A second AI model from another company (Claude Opus 5.5) reviewed the paragraph against the same sources. The 3GPP documents themselves govern.
