Highlights – 1Session 01, Setting the Scene
EU Telecom R&D programs designed to support standards with the goals• for 5G, to
• foster the emergence of global industry standards under EU leadership for key 5G technologies
• ensure that 5G standards are compatible with innovative use cases of vertical industries
• • for Internet of Things, to• foster an interoperable environment for IoT in cooperation with ESOs and
international SDOs
• promote an interoperable IoT numbering space and an open system for object identification & authentication
• explore options and guiding principles, including developing standards, for trust, privacy and E2E security
• promote the uptake of IoT standards in public procurement to avoid lock‐in areas such as smart city services, transport and utilities (including water and energy)

Highlights – 2Session 01, Setting the Scene
5G –“Massive” Requirements in terms of throughput, reduced latency, sensing, resilience, safety and security, fractal heterogeneity, which in addition are coupled• Revolution Ahead:
• ≤ 4G: Ubiquitous, Content Communications
• 5G: Ubiquitous, Steering & Control Communications, e.g. in Health & Care, Traffic & Mobility, Sports & Gym, Edutainment, Manufacturing, Smart Grid
• 5G Holistic View needed with• New architecture such as Mesh is dominant, Mobile Edge Cloud, Multi Link/Path
• New technologies such as Agile Cloud, Network Coding, Compressed Sensing,
• Integrated in SDN/NFV

FROM RESEARCH TO STANDARDIZATIONTake away session 2 – 5G Enablers

Highlights of SESSION 2: A selection of 5G Enablers, Chair: Francisco da Silva, Huawei
New Business models built on Micro-Operators:
Context: Versatile location and case specific requirements for different environments with high traffic densities, particularly in indoors, need to be met.
Barriers: Entry barrier to the mobile market is high due to the limited availability of spectrum licenses which today are high-cost, long-term and come with nation-wide coverage obligations.
Solution: Concept of micro-operators (uO) - they will build indoor small cell communication infrastructures and offer context related services and content in local areas to complement existing mobile connectivity with the help of emerging 5G technology and locally issued spectrum licenses.

Highlights of SESSION 2: A selection of 5G Enablers, Chair: Francisco da Silva, Huawei
Advanced modulation and random access techniques for 5G communication systems:
Requirements: 1000x higher mobile data volumes, 10-100x higher end user rates, 10-100x up to 300.000 devices per cell, 99.9999% for e.g. mission critical communications, decreased latency down to the millisecond scale, increased efficiency.
Barriers: A thorough re-design of the radio interface is needed to cope with 5G requirements.
Solution: Advanced post-OFDM waveform designs (FBMC), MAC protocol for massive random access (DQ).

FROM RESEARCH TO STANDARDIZATIONTake away session 3: On Future Network Architecture
Presented by Hermann Brand for workshop ‘From Research to Standardization’

Highlightssession 3: On Future Network Architecture (1)
Reduce backhaul traffic through pro-active caching at the base-station
Radically simplify networking based on RINA (Recursive InterNetWork Architecture):• Single generic protocol mechanism and policies, 3 nodes (host, interior
router, border router)
• Reduces protocol stack complexity and eliminates protocol overhead e.g. no mobility protocols needed any more in mobile networks
• RINA can be deployed as underlay, overlay, or gateway

Highlights session 3: On Future Network Architecture(2)
Common Meta-Data Gateway combined with a collaboration system for rescue agencies to share data/information despite
Introduce metrics, static analysis and feedback loops to ensure service quality is met according SLA

Issues raisedsession 3: On Future Network Architecture
Multiple trade-offs• between densification/backhaul offloading and caching
• between latency and capacity
Sharing data of different owners
Different ownership of network slices
Domain description standards are missing
Catalogue of metrics needed (statically and dynamically verifiable)

Link to ISG NGP has already been made for RINA• results from PRISTINE project used as input
• Validation of RINA approach in 5G context ongoing in H2020 ARCFIRE project
Identify committees/groups potentially interested in proposed analysis/solutions• ISG MEC and caching
Develop an ETSI Whitepaper

Hints to identify standardization topicssession 3: On Future Network Architecture
Separate algorithms from interfaces
What is needed to connect boxes/plug boxes together?
Generalise a solution for a specific use case to other use cases to identify commonalities as potential subjects for standardization
Abstract implemented functions and map functional entities to existing network entities: which interfaces/protocols need to be modified or are missing?
Prepare selling points for a technical solution to get supporters for standardization

FROM RESEARCH TO STANDARDIZATIONTake away session 5 “On Virtualization Techniques for 5G”
Presented by Julie Duclercq – Intel Mobile Communications

Highlights / issues raisedSession 5 On Virtualization Techniques for 5G
On Virtualization Techniques for 5G
5G will be more than a new radio interface
5G is about new network architecture: a unified programmable and shareable infrastructure to deliver Service Agility, Service Diversityand Resource efficiency - being future-proof and ready to serve even not yet identified use case and radio technologies
Different resources shared within virtualized network.
→ Orchestration needed to enable different apps with different
requirements.
Orchestration has to translate End-to-end services requirements in requirements for transport, processing and Radio Access Network.

On Virtualization Techniques for 5G
Network Virtualization will offer major opportunities, but comes with some challenges to be addressed like:• Support heterogenous infrastructures
• Align the interfaces for this virtualization.
• Align abstraction models for resources/services
