Phases should stay sequential. 11 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. GAPS IN THE CURRENT SET OF PROJECTS • Linkage to evolving an applications community - Need to track requirements and to link to stakeholders on the applications side - Allow app stakehoders to “play” with the new possibilities • Some topic areas will extend or split to allow for deeper coverage - Introducing more extensive evaluation: modeling, simulation frameworks - Attaching a targetted prototyping activity to accommodate for sufficient resources - Deeper coverage of specific topics • New questions will come up: - E.g. the impact of virtualization and multi-tenancy on “business” within the network, accounting is becoming crucial. This has significant regulatory and legal implications. 12 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. Examples for research questions resulting from cross-topics • Cross- projects: Some interactions between the “last” pre-structuring projects need more in-depth studies - This is currently being accounted for in bi-lateral interactions between the Px projects but dedicated studies need to follow Security aspects of Virtualization and Architectures P8: 5G Holistic Network Architecture Application Layers P13: 5G Network Security and Integrity P12: SLM & Metrics for QoS/QoE P10: 5G Services E2E Brokering and Delivery P11: Cognitive Network Management P9: Enabling Technologies Unified Control P16: Multi-Domain SW Networks Air interface: adaptation for MTC P14: Virtual Networks Platform P1: 5G Wireless System Design P3: 5G for Massive MTC Physical Layer P6: Novel Radio System Architecture P7: Backhaul/Fronthaul Integration P2: 5G Air Interface Rationalization / Common modules?

EXTENDED PARTNERSHIP MODELS - The interest in participation to the PPP projects is much larger than what they can handle - Many academic partners would like to join PPP, but cannot be accommodated - Many non-EU parties seek linkage - Currently captured in EU-Japan, EU-Korea, EU-China - This approach does not scale easily, there are many more candidates …. - Dilemma : If we increase the PPP projects size to accommodate more partners and parties, projects loose focus and efficiency - Consider a structured approach, creating a co-operation platform “around” the projects. 14 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. DEMOS AND PROTOTYPES – GENERAL CONSIDERATIONS • Demos should show - The mastering of a technical challenge - The impact of a new technology • Realization - Demos may be pure (software) models, just visualizing properties and impact of a technology - Can also consist of a prototype plus a human interface to allow for more insight - This is clearly the preferred type • De- risking and relevance - Prototypes should closely relate to the critical research questions of the project 16 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. DEMOS AND PROTOTYPES – GENERAL CONSIDERATIONS • Limited effort: - Prototypes rely on simplifications and abstractions to become viable (e.g. one scenario, few users) - Use abstractions for non-relevant parts - Lack of statistical richness: Generally, prototypes are not a good vehicle to answer performance questions (Apart from e.g. peak rates ) since they represent limited numbers of nodes and users - Realization perspective: Realization of a prototype leads to an implementation view and related learning. It adds another perspective to research. 17 COPYRIGHT © 2014 ALCATEL-LUCENT. ALL RIGHTS RESERVED. WHAT WOULD WE SEE IDEALLY ON PROTOTYPING?
