PRINCIPLES10KEY ENABLING TECHNOLOGIES 11SPECTRUM CONSIDERATIONS135G TIMELINE14Key drivers5G will not only be an evolution of mobile broadband networks.It will bring new unique network and service capabilities.Firstly,it will ensure user experience continuity in challenging situations such as high mobility(e.g.in trains),very dense or sparsely populated areas,and journeys covered by heterogeneous technologies.In addition,5G will be a key enabler for the Internet of Things by providing a platform to connect a massive number of sensors,rendering devices and actuators with stringent energy and transmission constraints.Furthermore,mission critical services requiring very high reliability,global coverage and/or very low latency,which are up to now handled by specific networks,typically public safety,will become natively supported by the 5G infrastructure.5G will integrate networking,computing and storage resources into one programmable and unified infrastructure.This unification will allow for an optimized and more dynamic usage of all distributed resources,and the convergence of fixed,mobile and broadcast services.In addition,5G will support multi tenancy models,enabling operators and other players to collaborate in new ways.Future European society and economy will strongly rely on 5G infrastructure.The impact will go far beyond existing wireless access networks with the aim for communication services,reachable everywhere,all the time,and faster.5G is an opportunity for the European ICT sector which is already well positioned in the global R&D race.5G technologies will be adopted and deployed globally in alignment with developed and emerging markets needs.EXECUTIVE SUMMARY5G disruptive capabilities5G will provide an order of magnitude Improvement in performance in the areas of more capacity,lower latency,more mobility,more accuracy of terminal location,increased reliability and availability.5G will allow the connection of many more devices simultaneously and to improve the terminal battery capacity life.Lastly,5G will help European citizens to manage their personal data,tune their exposure over the Internet and protect their privacy.5G infrastructures will be also much more efficient.The enhanced spectrial efficiency will enable 5G systems to consume a fraction of the energy that a 4G mobile networks consumes today for delivering the same amount of transmitted data.5G will reduce service creation time and facilitate the integration of various players delivering parts of a service.Lastly,5G systems will be built on more efficient hardware.The ultra-efficient 5G hardware will be energy aware,very flexible and interworking in very heterogeneous environments.The increased efficiency of the 5G infrastructure will allow costs to be dramatically reduced.Design principles5G design will ensure high flexibility and be driven by a service approach.The network shall flexibly and rapidly adapt to a broad range of usage requirements and deliver converged services preserving security and privacy across a versatile architecture with unified control of any type of ICT resources.Since 5G will enable new business models in a programmable manner,Application Programming Interfaces(APIs)should be available at different levels(resources,connectivity and service enablers)to support a variety of network and service application developers.Leveraging on the characteristic of current cloud computing,5G will push the single digital market further,paving the way for virtual pan European operators relying on nationwide infrastructures.5G will be designed to be a sustainable and scalable technology.Firstly,the telecom industry will compensate tremendous usage growth by drastic energy consumption reduction and energy harvesting.In addition,cost reduction through human task automation and hardware optimization will enable sustainable business models for all ICT stakeholders.Last but not least,5G will create an ecosystem for technical and business innovation.Since network services will rely more and more on software,the creation and growth of startups in the sector will be encouraged.In addition,the 5G infrastructures will provide network solutions and involve vertical markets such as automotive,energy,food and agriculture,city management,government,healthcare,manufacturing,public transportation,and so forth.4Key technological components5G wireless will support a heterogeneous set of integrated air interfaces:from evolutions of current access schemes to brand new technologies.5G networks will encompass cellular and satellite solutions.Seamless handover between heterogeneous wireless access technologies will be a native feature of 5G,as well as use of simultaneous radio access technologies to increase reliability and availability.The deployment of ultra-dense networks with numerous small cells will require new interference mitigation,backhauling and installation techniques.5G will be driven by software.Network functions are expected to run over a unified operating system in a number of points of presence,especially at the edge of the network for meeting performance targets.As a result,it will heavily rely on emerging technologies such as Software Defined Networking(SDN),Network Functions Virtualization(NFV),Mobile Edge Computing(MEC)and Fog Computing(FC)to achieve the required performance,scalability and agility.5G will ease and optimize network management operations.The development of cognitive features as well as the advanced automation of operation through proper algorithms will allow optimizing complex business objectives,such as end-to-end energy consumption.In addition,the exploitation of Data Analytics and Big Data techniques will pave the way to monitor the users Quality of Experience through new metrics combining network and behavioral data while guaranteeing privacy.Spectrum considerationsIt is expected that 5G access networks for some services will require very wide contiguous carrier bandwidths(e.g.hundreds of MHz up to several GHz)to be provided at a very high overall system capacity.To support the requirements for wide contiguous bandwidths,higher carrier frequencies above 6 GHz need to be considered.The consideration of any new bands for such services will require careful assessment and recognition of other services using,or planning to use,these bands.Maintaining a stable and predictable regulatory and spectrum management environment is critical for the long term investments.Research on this spectrum has to take into account long-term investments so that they can be preserved.The exclusive mobile licensed spectrum assignment methods will remain important even if new techniques may be envisaged to improve spectrum utilization under some circumstances.TimelineThe start of commercial deployment of 5G systems is expected in years 2020+.The exploratory phase to understand detailed requirements on future 5G systems and to identify the most promising technical options has already started.Although several standardization bodies will potentially be involved in the 5G definition,3GPP will be most probably the focal point for technical specifications,with 5G study items starting from 2015.INTRODUCTION1 Worldbank:Informati on and Communicati on for

ps:/ec.europa.eu/digital-agenda/en/scoreboard.This paper gives an overview of the 5G vision of the European ICT sector.It addresses the key drivers and disruptive capabilities for 5G as well as the design principles,key technological components,spectrum and timeline considerations.The strategic nature of the communicati on sector extends beyond its sole industrial domain,as the boundaries with the IT domain tend to blur.5%of European GDP,with an annual value of about 660 billion,is generated today by the ICT sector itself.Additi onal investment in ICT in Europe could contribute to a rebirth of GDP growth in Europe up to 1.21%points in high-income economies and 1.38%points in low and middle-income economies,as suggested by a report from the World Bank1.The overall employment level of the ICT sector in Europe has been rather stable between 7.2 to 7.5 million employees since 2002(Source:Digital Agenda Scoreboard2).European industry has been historically strong in research,development and integrati on of complex systems like communicati on networks as well as manufacturing criti cal systems.A wide spread and well-established research community in R&D centres and universiti es is cooperati ng with industry and SMEs for knowledge and IPR generati on.The novel 5G network requirements,technologies and architectures will introduce a wide range of industrial opportuniti es for both established and new actors among which SMEs.The 5G Infrastructure PPP is a unique opportunity for the European ICT industry to compete on the global market for 5G infrastructure deployment,operati on and services.65G will bring new unique service capabilities for consumers but also for new industrial stakeholders(e.g.vertical industries,novel forms of service providers or infrastructure owners and providers).Firstly,it will ensure user experience continuity in challenging situations.HD video or teleworking will be commonplace and available anywhere,regardless of if the user is in a dense area like a stadium or a city centre,or in a village or in a high speed train or an airplane.5G Systems will provide user access anywhere and will select transparently for the user the best performing 5G access among heterogeneous technologies like WiFi,4G and new radio interfaces.The choice of the best performing access will not only be based on throughput but on the most relevant metrics depending on the nature of the service e.g.latency may be more important than throughput for an online game.In addition,5G will be a key enabler for the Internet of Things by providing the platform to connect a massive number of objects to the Internet.Sensors and actuators will spread everywhere.KEY DRIVERS4G was designed for improving capacity,user data-rates,spectrum usage and latency with respect to 3G.5G is more than an evolution of mobile broadband.It will be a key enabler of the future digital world,the next generation of ubiquitous ultra-high broadband infrastructure that will support the transformation of processes in all economic sectors and the growing consumer market demand.The following paragraph intends to give an insight on what makes 5G so special.Since they require very low energy consumption to save battery lifetime,the network will have to support this effectively.Objects,users and their personal network,whether body worn or in a household,will be producer and consumer of data.Future smart phones,drones,robots,wearable devices and other smart objects will create local networks,using a multitude of different access methods.5G will allow all these objects to connect independently from a specific available network infrastructure.Furthermore,some mission critical services will become feasible natively on the 5G infrastructure thanks to the unprecedented performance achievable on demand.It will cover services which were handled by specific networks for reliability reasons such as public safety.It will also cover new services requiring a real time reactivity such as Vehicle-to-Vehicle or Vehicle-to-Road services paving the way towards the self-driving car,factory automation or remote health services.As a conclusion,5G needs to support in an efficient way three different type of traffic profiles,namely high throughput for e.g.video services,low energy for eg.long lived sensors and low latency for mission critical services.In addition,5G infrastructure will cover the network needs and contribute to the digitalization of vertical markets such as automotive,banking,education,city management,energy,utilities,finance,food and agriculture,media,government,healthcare,insurance,manufacturing,real estate,transportation and retail.An opportunity to launch brand new services2FIGURE 1.5G new service capabilitiesUSER EXPERIENCE CONTINUITY INTERNET OF THINGS MISSION CRITICAL SERVICES A unified telecom and IT infrastructure ready for multi-tenancyA sustainable and scalable technologyA larger ecosystem,more open to new players,start-ups and other sectorsOur vision is that in ten years from now,telecom and IT will be integrated towards a common very high capacity ubiquitous infrastructure.In order to assure the required scalability and flexibility,the network functions will be more and more“virtualised”on general purpose,programmable and specific high performance hardware that will offer resources for data transport,routing,storage and execution.5G will integrate telecom,compute and storage resources into one programmable and unified infrastructure which will allow for an optimized usage of all distributed resources.The wireless part of global network connectivity will grow from 45%in 2012 to 75%in 2020(UMTS Forum3),with Wi-Fi covering close to 50%of total connectivity.Consumers as well as vertical business segments will want to use a unified wireless and wireline telecommunication network for an extreme variety of services.Being unified,5G infrastructure will offer natively converging capabilities for fixed and mobile accesses,as well as for broadcast and broadband networks.In addition,this infrastructure will be ready for multi-tenancy.Operators will add to their services portfolio the possibility to be asset providers(infrastructure,network functions,platform offered as a service)for other operators or other players like integrators.Leveraging on this fundamental design principle will push the single digital market further,paving the way for virtual pan European operators relying on nationally deployed infrastructures.5G systems have to resolve the fundamental challenge of handling the anticipated dramatic growth in the number of terminal devices,the continuous growth of traffic(at a 50-60%CAGR),and heterogeneous network layouts without causing a dramatic increase of power consumption and management complexity within n
