# 3GPP TR 26.836 V0.0.1 - Study on QUIC-based Media Delivery Solutions for Real-Time Communication (Release 20)

## Document Overview

This is an initial skeleton document for a Technical Report studying the application of QUIC-based media delivery protocols to 3GPP Real-Time Communication (RTC) systems. The document is in its early draft stage (V0.0.1) and contains primarily editor's notes outlining the intended structure and scope of the study.

## Main Technical Scope

The study aims to evaluate QUIC-based media delivery protocols for integration into the 3GPP RTC system, examining their applicability, benefits, limitations, and potential architectural impacts.

## Technical Content Structure

### 1. QUIC-based Media Delivery Protocols (Clause 4)

**Objective:** Survey and document existing and emerging QUIC-based media delivery protocols.

**Planned Content:**
- Individual protocol descriptions including:
  - Introduction and features
  - Benefits and limitations from RTC perspective
  - Current applications
- Summary and comparison of surveyed protocols

**Note:** Comparison with existing RTC system will be addressed in the evaluation clause rather than here.

### 2. Evaluation of QUIC-based Protocols for RTC (Clause 5)

This clause forms the core technical contribution, structured into three main evaluation dimensions:

#### 2.1 Application Scenarios (Clause 5.2)
- Definition of potential RTC service scenarios where QUIC-based media delivery could be applied
- Individual scenario descriptions to be provided in subsequent subclauses

#### 2.2 Architectural and Functional Evaluation (Clause 5.3)

**Scope of Analysis:**
- Impacts on RTC media delivery architecture (TS 26.506)
- Impacts on 5G Core Network architecture (TS 23.501)
- Impacts on UE implementations

**Per-Protocol Analysis:**
- Applicability to defined application scenarios
- Potential architectural enhancements required for integration
- Advantages and disadvantages for each scenario
- Summary of findings

#### 2.3 Performance Evaluation (Clause 5.4)

**Methodology:**
- Utilizes test framework from TR 26.934 ("Test platform for media delivery technologies")

**Content:**
- Definition of appropriate performance metrics for QUIC-based protocols
- Per-protocol evaluation including:
  - Evaluation conditions
  - Results obtained using TR 26.934 framework

#### 2.4 Evaluation Summary (Clause 5.5)
- Overall assessment including:
  - Advantages and disadvantages for RTC system
  - Benefits for application scenarios
  - Performance evaluation results

### 3. Integration into RTC System (Clause 6)

**Conditional Scope:** This clause will only be populated if QUIC-based protocols are found beneficial based on Clause 5 evaluation.

**Planned Content:**
- Potential integration scenarios
- Candidate solutions for integration
- Summary of solutions including:
  - Evaluation/comparison of solutions
  - Potential normative work requirements

### 4. Conclusions and Recommendations (Clause 7)

Final conclusions and recommendations based on the study findings.

## Key Dependencies and References

- **TR 26.934:** Test platform for media delivery technologies (used for performance evaluation framework)
- **TS 26.506:** RTC media delivery architecture (baseline for architectural evaluation)
- **TS 23.501:** 5G Core Network architecture (for network-level impact analysis)

## Study Approach

The document follows a systematic evaluation methodology:

1. **Survey Phase:** Identify and characterize QUIC-based protocols
2. **Scenario Definition:** Define relevant RTC application scenarios
3. **Multi-dimensional Evaluation:** Assess protocols from architectural, functional, and performance perspectives
4. **Integration Analysis:** Develop potential integration solutions (if justified)
5. **Recommendations:** Provide conclusions and guidance for potential normative work

## Current Status

This is a skeleton document (V0.0.1) from SA4#135 (February 2026) containing only structural placeholders and editor's notes. No technical content, evaluation results, or specific protocols have been documented yet. The structure indicates a comprehensive study approach covering protocol analysis, scenario-based evaluation, and potential standardization pathways.
