**Source:** Huawei | **Spec:** TR 26.870 | **Meeting:** SA4#135-bis-e

---

**What is being proposed:**
- A partial CR (pCR) to update Section 6.2.1.5 of TR 26.870 (FS_6G_MED study item), adding discussion directions under Key Issue 1.

**Changes made:**
- Two study questions are added to Section 6.2.1.5:
  1. Whether the media delivery architecture for **streaming and real-time communication services should be harmonized or separated**, and what the trade-offs are between shared components vs. service-specific optimization.
  2. Which **existing and emerging content delivery protocols** map to the 5G Media Delivery architecture, and what extensions/simplifications are applicable for 6G Media Delivery.

**Context:**
- The starting point for discussion is the existing 5G Media Delivery architecture.
- The study aims to address a diverse set of media applications and traffic patterns under the 6G media delivery framework.

**Nature of change:** Editorial/structural — adds scoping questions to guide further study; no normative technical decisions are made.

**Action requested:** Approval.
