[FS_ULBC] On the scheduling timing uncertainty
Based on my review of the document, there are no proposals explicitly marked as "Proposal" (with any of the variations mentioned) in this 3GPP document.
The document contains proposed changes to a PD (Permanent Document) version 0.4.0, specifically modifications to section 5.2.2.3 on Frame structure, but these are presented as "Proposed change" rather than formatted as numbered or unnumbered proposals in the standard proposal format.
