In plain words
"The IE PosSRS-RRC-Inactive-OutsideInitialUL-BWP is used to convey the capabilities supported by the UE for SRS for Positioning transmission in RRC_INACTIVE state configured outside initial UL BWP." This information element (IE) appears in TS 38.331 V19.4.0 and has 13 fields, including limits on SRS resource counts and bandwidth. Its 13 fields match the Rel-17 count, so the field count has not grown since Rel-17.

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.
