In plain words
TS 38.104 describes itself as "single-RAT specification for a BS, covering RF characteristics and minimum performance requirements.". Here, BS means base station, and the specification has a single-RAT scope. It establishes minimum RF characteristics and performance requirements for NR and NB-IoT operation in NR in-band Base Station. V20.1.0 includes CRs on EESS protection for 40GHz in Japan, SBFD-capable BS requirement applicability, and square filter definition.

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.
