Summary

Clark Chen China Mobile Senior Researcher

the 5 requirements derived from use cases, operator value proposition and business modelsUser experience requirements: consistent, efficient support of data rates, support of ultra low-latency、 support of high mobility, device power efficiencySystem performance requirements: cost efficiency throughput coverage, connection density, area capacity, spectrum efficiency, resource & signaling efficiencyEnhanced service requirements: seamless connectivity, context awareness, security, high availabilityNew business enabling: evolution of bit pipe model, X-aaS business models, Network sharingManagement & Operation requirements: cost efficiency, energy efficiency, ease of innovation & upgrade, ease of deployment, flexibility & scalability, operational awareness, operation efficiency

Session Chair


5G system will be defined from both the user and operator perspectives. It is essential that the operators & vertical service providers can actively participate in Taiwan 5G project planning. It will be important to encourage more involvement or leadership of local mobile operators.For the 5G project planning, it is vital to take on the E2E system service view. It will be good to select a few of 5G use cases or scenarios as the system integration master plan, instead of working on a few separate technology items.

Emerging Network Topologies for Further Reduced End-to-End Latency

20

Software-Define Network (SDN) could reduce core network

transport delay

Cloud-Radio-Access-Network (C-RAN) Centralized BB processing and load balance could facilitate RAN resource allocation and reduce radio access network processing

delay

Device-to-Device (D2D) communications could significantly eliminate

network processing delay

This should be under further research.

• The 5G requirements focused on “user-centric” or “business-centric” will have significant effects on the 5G architecture and technical design.

• The operators are trying to claim more important roles in 5G definitions.

• With the multi-dimensions of requirements, some of them might dictate a major revolution of 5G system.

Conclusions

NGMN WorkStream (WS.3)-Technology and Architecture

22

Dr. Mikio Iwamura, Director of Wireless Research, NTT DOCOMO, Germany

Through four tasks listed as Analysis, Trends, Technologies (need giant step), and Architecture (Design Principles), this work stream will focus on gap analyses, leverage technology trends, and technology components (such as Spectrum Access, Duplex Mode, SDN, Small Cell Network, etc.) to prepare the initial white paper

Need to have a generic view on architecture for wireless 5G

Session Chair


There will need a disruptive change on requirements , technology advanced, and services creations from current 4G to the future 5G. Many of potential Key technologies which have been mentioned in this Forum (such as SDN, Small Cell Network, Smart Data Pricing and Fog Networking and Computing) are Taiwan’s strength. We need to integrate all R&D resources to start a very focused initiative to develop/secure necessary essential IPRs and deliver a Demonstrable Working End-to-End System (e.g. F-RAN) within 3 Years.


23Source : Professor Mung Chiang, Princeton University

Conclusions

• Wireless 5G will essentially be “Services & Applications Driven”

• Small Cell Network, Soft-Defined Network (SDN), Smart Data Pricing, Cloud-Based Radio Access Network (C-RAN), and Fog-Based-Radio Access Network (F-RAN) will be key essential technology for both Architecture and Technology in Wireless 5G.

• Let’s concentrate our resources and commitment to: (1)Deliver a demonstrable end-to-end working system within 3 years, and (2) to establish/secure key and essential IPRs for Wireless 5G

NGMN WorkStream (WS.4)-Spectrum

25

S. Apetrei from Orange

Spectrum above 6/10 GHz is needed for very high data rate, below 1GHz for larger coverage, as well as spectrum for shorter-range connectivity

NGMN operators fully support flexible usage of spectrum including licensed share and license exempt, in addition to the original (preferred) licensed access

Session Chair


Re-farming and open more spectrum for sharing - based on the ITU WRC-15 rules - by Taiwan regulatory bodies (e.g., NCC and MoT) is desperately needed

Expedite and leverage R&D capacity such as cognitive radio and dynamic spectrum access (DSA) for spectrum sharing


Spectrum Access• Exclusive licensing regimes should remain the preferred solution

– enable guaranteed QoS and support global roaming • Supplementary spectrum made available on a shared basis

– Additional licensed spectrum made available by an incumbent governmental or public user– license-exempt spectrum chapter

Spectrum flexibility

• Spectrum flexibility can bring benefits of spectral efficiency gains– Unlicensed spectrum can serve as a complement,

particularly if it is aggregated with licensed spectrum to increase bandwidths

Spectrum Availability• Unused VHF bands in sub-1 GHz bands

– Available bandwidth: 30 to 200 MHz– Long-distance non-line-of-sight communication (Super WiFi)– Already being tested in rural and urban broadband(US, UK, Singapore,

Kenya, etc)– New generations of long-range sensor networks (IoT)

• 3.5 GHz band– Available bandwidth: 100 MHz in the 3550-3650 MHz). – Small cell and spectrum sharing

Spectrum Availability (cont.)

• 5 GHz band– Available bandwidth: 775 MHz in the US.– 100 more MHz available in 5.15 to 5.25 GHz band in US– Short-range transmission (5.8 GHz for LTE-U)– longer-range, point-to-point gigabit link (wireless backhaul)

• 60 GHz band– Available bandwidth: 7 GHz– Short-range, ultra-fast communication to mobile devices– line-of-sight backhaul from small cells

• Other bands between 6-10GHz, 28GHz, 38GHz, etc

Conclusions

• Sharing is NOT a synonym of compromised service. Instead, it provides great flexibility for providing QoS services to end users– Via offloading or smart aggregation

• The question is where or not we should implement spectrum sharing. The question is how

• Global harmonization (ITU WRC 15), local regulation and new architecture in place

NGMN WorkStream (WS.5)- IPR Management and Challenge

32

Luke Ibbetson / Head of Group Research & Development – Technology / Vodafone Group Service Limited/ Newbury, Berkshire, United Kingdom

The Basic tenet of this work stream is as follows: The current IP structure for 3G and 4G may not be fit for purpose to support 5G deployment 5G IPR costs must be predictable and manageable The 5G IPR structure must stimulate and reward innovation “Royalty stacking” is perceived to be a significant issue in keeping device costs high

Session Chair


In terms of IPR, there are at least two lines of opportunities that Taiwan should seize at present in the 5G endeavor: The F-RAN conceptual framework, proposed by our Taiwan team, was well received by the

audience in general and Mr. Chen of China Mobile and the editor-in-chief of the white paper, in particular. The Taiwan team is scheduled to meet with China Mobile this September to further discuss this matter. Thus, firms and research institutes in Taiwan should speed up R&D activities and patent application under the F-RAN structure.

To reflect Taiwan’s voice on IPR structure to NGMN. The experiences of Taiwanese firms in mobile industry regarding their dealing with major IP holders should be collected and compiled. Then, argument should be elaborated and presented to WS5 for their consideration in the writing of the final paper.


• By interviewing the CTOs of Taiwan's major firms in the telecom industry & Opterator, to learn of their experiences and comments on current IP related matters.

• With the multi-dimensions of requirements, some of them might dictate a major revolution of 5G system.

• “Royalty stacking” solution: Cross licensing and patent positioning to reduce high cost.

• Base on F-RAN conceptual framework, combine Taiwan ICT and Telecom strength, file the cross discipline patents with the synergy.
