Project Coordination Group (PCG)

3GPP Organisation

3GPP – The 3rd Generation Partnership Project (“the project”)

PCG – Coordination of 3GPP by the Organizational Partners (OPs)

Technical Specification Groups (TSGs) covering different aspects of 3GPP system & process

TSGs are organized into Working Groups (WGs)

TSGs meet 4 times a year in the so-called “Plenary meetings” (co-located)

WGs meet once or more per plenary cycle (mostly not co-located)

Each TSG and each WG elects its own leadership (2 year terms / 2 terms)

Technical work is mostly done in WGs

Overall planning and coordination in TSGs

3GPP Eco-System

The 3GPP Organizational Partners (OP) are the seven Standards Developing Organizations (SDOs) - from China, Europe, India, Japan, Korea and the United States.

Participation in 3GPP is made possible by companies and organizations becoming Individual Members (IM) of one of the OPs.

Specific inputs, in the form of market requirements may also come in to the Project via any of the twenty Market Representation Partners (MRP) in 3GPP. These organizations have all signed up to the 3GPP Project scope and objectives.

Lots of external cooperation with other standards bodies and a broad variety of other groups, by way of formal Liaisons.

3GPP TSG#84 5

3GPP works based on

• Participation in face-to-face meetings

• Pro-activity & Contributions – you need written proposals to get attention

• Consenus – nobody says “no” in order to progress

Work organization

• Study Items, Work Items

• Releases with fixed time-lines, which are partially overlapping

• Work Plan (good overview)

3 stages, often overlapping

• Stage 1: Requirements

• Stage 2: Architecture

• Stage 3: Protocols

3GPP – How It Works

362 Companies actively participate in the 3GPP work

• From all over the world

• All major telecommunication companies – operators, network/device/chipset vendors

• More and more vertical industry representatives bring their work directly to 3GPP

Amazing Track Record

• 3GPP started 1998, since then all major standards projects were deployed

• e.g. 3G/UMTS, 4G/LTE, VoLTE/IMS, NB-IoT

• Seamless migration from “old” to “new” technology generations

A new Release every 15 to 24 months

• Allows for resonably fast standardization & deployment of new ideas

• Strong comittment to time-lines gurantees reliable planning and time-to-market

• New technologies get easily introduced (IP, IoT, AI ...)

Liaisons Persons to MRP meetings

Much better overview on where relevant vertical work takes place

More transparent processes

Better understanding of what are the long-term expectations of specific MRPs.

3GPP TSG#84 31

Resources

3GPP is based on • Written input contributions

• Face-2-Face meetings

• Consensus – you need to actively convince other parties

• Work spawning over several groups in parallel

Verticals need to make sure to• send delegates to all groups in which their topics are handled

• provide long-term participants in these groups

• support other players in their work in order to more acceptance in community

© 3GPP 2019

3GPP TSG#84 32

Step-Wise Approach

3GPP is based on • Releases, usually between 12 and 24 month long

• Iterative approach – a topic can spawn over several releases

• Work Items – usually on stage 2 / 3only covering a technical sub-area

Verticals need to make sure • to align their views in a way that they requirements are met per release

• to plan their requirements so that they can be processed in different WIs

• to move parts of their work into more general WIDs (e.g. URLLC)

Verticals have worked successfully in Rel-16, -15 and earlier

Rel-17 content will be fixed during next months – only small adjustments are still possible

Plan new ideas for Rel-18

Key steps for verticals / MRPS• Coordinate amongst each other & with other players

• Provide necessary resources

• Propose new (gradual) improvements

Let us tackle open issues together• How to gain more awareness of vertical views on all levels of 3GPP?

• How to reflect better vertical industries product cycles and approaches?

Tasks/Questions for the 2nd Vertical WS

1. Identify concrete targets and set clear actions for the way forward.

2. Is there anything still needed from Rel-17?If yes: clear contribution & action plan how to get this in

3. How to organize vertical work on Rel-18?How to identify common requirements and (more critical) common technical solutions?

4. How do verticals want to communicate their long-term plans to 3GPP?

5. How can verticals work together to make “their case” more attractive to other players in 3GPP and the industry?
