# Discussion Paper on FS_Energy_Ph2_MED Next Steps

## 1. Background and Issue

The Study on Media Energy Consumption Exposure and Evaluation Framework Phase 2 (FS_Energy_Ph2_MED) is facing schedule challenges. The study was originally planned for completion at SA4#135, but significant work remains outstanding.

### Current Status
- Only 4 out of 14 Tdocs submitted to the SA4-e (AH) MBS SWG post 134-2 have been reviewed
- Only 2 Tdocs reached consensus
- A significant number of new candidate solutions are expected at SA4#135
- Consensus is still required on:
  - Conclusions, including selection of candidate solutions for key issues
  - Recommendations listing proposed normative changes
  - Stage 2 Work Item Description (WID)

### Original Planning Constraint
The original plan required Stage 2 WID agreement at SA4#135 to allow:
- Two SA meetings (SA#112 June 2026, SA#113 September 2026) for Stage 2 completion
- Two additional meetings (SA#114 December 2026, SA#115 March 2027) for Stage 3 finalization
- Meeting the Release 20 Stage 3 freeze deadline (SA#115 March 2027)

## 2. Remaining Work for Meaningful Stage 2

### Phase 1 Context
Phase 1 of TR 26.942 recommended normative work for Key Issue #1 (Energy-Related Information Exposure) based on:
- Energy Information Function (EIF) within 5G System (TS 23.501)
- Two new entities: Energy Information Application Function (EIAF) and Energy Information Collector (EIC)

### Phase 2 Progress
- EIF capabilities and interfaces are now clearly defined
- Architecture and procedures related to energy information management have been validated through discussions
- However, agreed Change Requests are insufficient to fully identify necessary Stage 2 actions

### Critical Outstanding Items
To enable meaningful Stage 2 work, the following key points must be addressed:

1. **Baseline Procedures Update**: Incorporate new EIF capabilities and interfaces information; confirm whether Energy Information Collector will be used
2. **Energy-Related Information Exposure Provisioning**: Clarify what Step 1 of baseline procedures entails
3. **AS Energy Information Report**: Clarify report contents
4. **Network Energy Information Delivery**: Clarify different options for sending Network Energy Information to UE

## 3. Feasibility Assessment for SA4#135

The following tasks appear very challenging to complete during SA4#135:
- Agree on candidate solutions addressing the key points listed in Section 2
- Reach consensus on conclusions, including candidate solution selection
- Reach consensus on recommendations listing proposed normative changes
- Agree on Stage 2 WID

**Conclusion**: The work plan requires adaptation.

## 4. Proposed Solution and Revised Planning

### Proposal
Postpone FS_Energy_Ph2_MED completion from SA4#135 to SA4#136, providing two additional SA4 meetings to finalize the study. This approach would:
- Complete the study at SA4#136
- Address Stage 2 in a single meeting (SA#136)
- Complete Stage 3 in two meetings
- Still meet Rel-20 Stage 2 freeze and address Release 20 SA1 requirements

### Enabling Measures
To make this feasible:

1. **Freeze New Candidate Solutions**: Prevent submission of candidate solutions that have not already been discussed after SA4#135
2. **Early WID Consensus**: Reach consensus on Stage 2 draft WID during SA4#135-bis e-meeting
3. **Early Stage 2 Work**: Begin work on new Stage 2 Technical Specification prior to WID approval at SA#112 by:
   - Submitting discussion papers to SA4#135-bis e-meeting and/or SA4#136
   - Including early drafts of TS 26.nnn V0.0.1/V0.0.2 based on agreed baseline of Solution 5

### Next Steps
Once consensus is reached on this proposal, the related workplan will be updated accordingly.
