In plain words

MIMO-ParametersPerBand conveys "MIMO related parameters specific for a certain band (not per feature set or band combination)". Its fields cover transmission coherence, beam reporting, beam management, and receive beam limits. In TS 38.331 V19.4.0, the SEQUENCE has 263 fields: 36 from Rel-15, 30 from Rel-16, 70 from Rel-17, 65 from Rel-18, and 62 from Rel-19.

How this page was made

The facts box comes straight from the 3GPP TDoc list and specification archive 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.
