In plain words
The specification says this information element (IE) conveys "spatial relation for SRS for positioning related parameters.". In 3GPP TS 38.331 V19.4.0, SpatialRelationsSRS-Pos is a six-field SEQUENCE covering SSB, CSI-RS, PRS, and SRS relations for serving and neighboring cells. Its field count matches Rel-16, so the available structure shows no increase in fields between Rel-16 and V19.4.0.

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.
