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

This is a Change Request (CR) document (S4-260238) that proposes modifications to specification 26.117, but it does not contain any sections labeled as "Proposal", "Proposal:", "Proposal X:", etc. The document contains:

- A reason for change
- A summary of change
- Technical specifications and requirements
- But no formally marked proposals in the format typically found in 3GPP contribution documents

The document appears to be a CR form that directly specifies changes to be made to the specification rather than proposing them in the typical proposal format.
