Proposal: refers to the communication proposal submitted by each company or organization;
Technical report: It is a report formed after the technical proposal has been evaluated by WG and accepted by TSG;
Technical specifications: WG re-evaluates the performance of proposals and technical reports. If there are no mistakes, technical specifications can be formed, and then they can become 3GPP specifications after being accepted and approved by TSG.

Take 37.885 as an example to download the technical report.
