Proposal

We propose to include the following information in TR 26.958 under Section 4 (and a new subsection for external format analysis under Section 11), addressing SID Objective 2c:

Document the KHR_gaussian_splatting extension as the emerging industry baseline for 3DGS representation in glTF, including its attribute semantics, SH coefficient organization, backward-compatible fallback via POINTS, and extensibility mechanism.

Document the MPEG_gaussian_splatting_transport extension being developed within MPEG-I Scene Description, including progressive download, timed delivery for dynamic 4D Gaussian splat sequences, and alternative SH coefficient layouts (mpegProgressive and mpegPerChannel).

Document the two-layer architecture (Khronos semantics + MPEG transport) and its suitability for 3GPP service integration, noting the alignment with the glTF-based approach already used in TS 26.118 and TS 26.119.

Proposal: It is proposed to agree the following changes to 3GPP TR 26.958.

Proposal: Include the following changes in the draft TR.

Proposal: develop mappings for 3DGS content generation and sharing work flows to an MSE framework and to IMS DC architecture.

Proposal: It is proposed to add the text above in section 6.3.X or other suitable section of TR 26.958.

Proposal 1: Agree the changes to 3GPP TR 26.958 as described in clause 4 of this contribution, introducing a new clause 9.2.3 on viewport-adaptive workflow with capability negotiation for large scenes.

Extracted Proposals

This document does not contain any proposals. The document describes technical specifications for high-level media data workflows for All-in-client configuration in 3DGS media delivery, but no sections are explicitly marked as "Proposal" in any of the standard formats.

Proposal 1: Capture the description and characteristics of the client-server configuration for 3DGS media data workflows as described in clause 9.2 in TR 26.958.

Extracted Proposals

This document does not contain any proposals. The document is a Change Request (CR) for 3GPP TR 26.958 that describes the mapping of 3DGS (3D Gaussian Splatting) services to different 3GPP services/specifications for the All-in-UE configuration, but it does not include any sections explicitly marked as "Proposal" with the various formats mentioned.

Proposal: The functions of different workflows for this configuration are described in clause 9.2 of the present document. Below is a mapping of those functions to 3GPP services. In this configuration, 3DGS is delivered as an interactive XR service or 6DoF media streaming.

Proposal 1: A mapping of application flows corresponding to 3DGS services to 5QI is identified.

Proposal 2: The 5QI values of those services, listed in clause 6.X.1 of the present document, that have similar QoS/QoE expectations and resource priority at RAN level, as that of 3DGS services, may be used as a reference to identify 5QI values and the corresponding QoS characteristics limits for 3DGS services.

Proposal 3: If required, liaise with necessary 3GPP groups to define the 5QI and corresponding QoS characteristics to 3DGS services
