In plain words
TS 38.306 defines the "NR UE Radio Access Capability Parameters". V19.4.0 CR subjects include correction on the component of sbfd-Aware capability and corrections on the MIMO UE Capabilities-r19. They also cover less than 5 MHz FR1 for (e)RedCap UE and introduction of support for CHO triggering events. Other subjects are correction on MHI for SCG active duration, clarification on 6 DL MIMO layer, and addition of ntn-NeighbourCellInfoSupport-v19xy.

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.
