Based on my analysis of the document, there are **no proposals** explicitly marked in this 3GPP document.

This document is a Change Request (CR) form for TS 26.512, which contains technical corrections to CMCD phase 1 implementation. While it describes changes to be made to the specification, these changes are presented as modifications to existing clauses rather than as formal proposals in the format you specified (e.g., "Proposal X:", "Proposal:", etc.).

The document contains:
- A reason for change
- A summary of change
- Technical modifications to clauses G.5.2.2 and G.5.2.4

But no sections explicitly labeled as "Proposal" in any of the formats mentioned.
