And yet analysts are projecting the expected results from 5G technology while the early stages of trials and pre standardized deployments are just beginning and commercial 5G deployment is clearly on the horizon All of this may be enabled through the ltE-Advanced and 5g specifications created by hundreds of contributing scientists and engineers at the Third Generation Partnership Project (3GPP). The transformation to 5G will also transform our lives, our economy, our jobs, our industries. The early signs are beginning to show Wearables are developing in such a way that they may become self-contained mobile computing devices, for example the cellular Apple Watch or connected glasses. The big expectation is the connected car; autonomous vehicles will give us back commute time for new activities in our lives The healthcare system is changing as remote monitoring and robotic surgery provides a different level of care. Drones will be used for transportation, surveillance and rescue operations. Robots and artificial Intelligence(Al)will result in a new relationship for both humans and machines. The wireless industry is virtualizing; Multi-Access Edge Computing(MEC)is going to redefine computing itself and certainly impact the mega-networks of things in the future.. billions of connected things.. billions of connected people and a major shift in network operations and management Since the wireless industry coalesced around Long-Term Evolution(LTE) in recent years, it has brought together the entire mobile industry, evolving deployments to a single technology, enabling an ecosystem larger than ever before. Already more than a quarter of all global mobile subscribers are using(LTE) and it's expected that by 2021 this will increase to more than half. While lte deployments continue to expand and grow across the world, certain regions such as Korea, Japan, China and the U.S. have nearly reached or exceeded 90 percent penetration of LTE. This pushed up the focus in the mobile industry towards 5t Generation(5G)mobile technology standards development, demos and trials. There continues to be growing demands for higher throughputs and more data capacity, particularly for video, to provide better broadband services. But data demand is just one of the drivers for 5G. In addition, 5G is targeted to address new vertical markets including massive Machine-Type Communications(mMTC), Ultra-Reliable Low Latency Communication(URLLC) and a broad range of Internet of Things(loT) applications in general The evolution of LTE(LTE-Advanced Pro) continued its standardization in 3GPP Rel-14, which was frozen by mid 7 and potentially ended specifications on LTE -a decade since its initial specification in Rel-8 included features such as further Multiple-Input Multiple-Output(MIMO) antenna enhancements, Carrier Aggregation(CA)enhancements, enhanced Licensed Assisted Access(eLAA), enhanced LtE Wireless Local Area Network Aggregation LWaeLWA), Voice-over-LTE VOLTE)enhancements and GSMA Intelligence. 1 March 2018 enhancements to Proximity Services/Device-to-Device(Pro Se/D2 D ) Rel-14 also focused on the study items towards the 5th Generation (5G)mobile wireless technology and architecture, therefore the initial work on the 5g standards As in the past, the International Telecommunication Union(ITU) is providing guidance, requirements and recommendations that are setting the stage for this next generation of mobile wireless technologies. Just as the itu defined International Mobile Telecommunications-2000(IMT-2000)to drive towards Third Generation(3G), and IMT-Advanced to drive towards Fourth Generation (4G), the ItU now is defining IMT 2020 to drive towards 5G specification. As the name implies the IMT-2020 process is targeted to define requirements, accept technology proposals, evaluate the proposals and certify those that meet the IMT- 2020 requirements, all by the 2020 timeframe 3GPP defined a two-phased 5G work program starting with study items in Rel-14 followed by two releases of normative specs spanning Rel- 15 and Rel-16 with the goal being that Rel- 16 includes everything needed to meet IMT-2020 requirements and that it will be completed in time for submission to the IMT-2020 process for certification The 5G work in 3GPP on Rel- 14 study items focused on both new Radio Access Network(RAN) technologies and new System Architecture(SA)aspects. The studies on new Ran technologies for 5G are called New Radio(nr)and are focused on defining a new radio access flexible enough to support a much wider range of frequency bands from <6 GHz to millimeter wave(mmWave)bands as high as 100 Gigahertz(GHZ). Given this wide range of carrier frequencies that must be supported, Orthogonal Frequency Division Multiplexing(OFDM) will be the basis for the 5G NR air interface. All new, state-of-the art frame structures, coding, modulation, MIMO, beamforming, etc. technologies were investigated as part of the 5G nr study item. Given this was the first 3GPP technology targeted at providing optimized performance in the mmWave bands, much of the focus in 3GPP 5G NR is on channel modeling and radio access features designed to address the quasi-optic nature of mmWave communications. In parallel, the System Architecture(SA) groups in 3GPP studied the Services and Markets Technology Enablers(the SMARTER study) that will drive the next generation system architecture, which has led to design principles, requirements and target deployment scenarios for the 5G network architecture. This has led to the identification of many key issues that need to be addressed as part of defining the 5G network architecture such as the support for Network Slicing, Quality of Service(Qos), Mobility and Session Management, Policy, Security and more Rel-15 began work on the first phase of normative specifications for 5G. Following numerous requests from leading companies, 3GPP escalated their timeline for Rel-15 Non-Standalone 5G New Radio(nSa 5G NR)specifications which were completed December 2017. The 5G NSA specifications have an LTE anchor for the control plane communications with a 5G nr cell to boost user data. The Rel-15 Standalone 5G NR specification will offer a full suite with a standalone nr system with no reliance on Lte. the new core for Rel-15 will provide interaction with the Evolved Packet Core(EPC)4G system with orchestration virtualization a clearly separate control and user plane and signaling architecture. Network slicing and Service Level Agreement (SLA)for groups of devices of new vertical industries and services will be provided for by the 5G core specifications. Rel- 15 SA NR specifications were completed in June 2018 To meet the timeline and full compliance with ITU IMT-2020 requirements, the standardization in Rel-16 continues to progress. Definition of the study items and work items was completed in July 2018, on schedule, with the option of adding additional Study Items/ Work Items (sIs/Is)in the future, as needed Rel-16, or phase 2 of 5G, will primarily address any outstanding issues in Rel-15, expansion of 5G technology features and increased 5G efficiency. Expansion of 5G will include New Radio(nr)based Cellular-Vehicle to Everything(C-v2X)capabilities, Industrial loT, enhancements to Ultra-Reliable Low Latency Communications(URLLC) and 5G in operation in unlicensed spectrum and above 52.6 GHz. 5G efficiency improvements will include enhancements to 5G Self-Organizing Networks SON) and Big data capabilities, MIMO enhancements, improved power consumption, support for device capabilities exchange, and a study of support for non- orthogonal multiple access(MOMA) This paper provides a detailed status of key areas of work in 3GPP on Release 14 LTE enhancements and studies towards definition of the radio access and system architecture for 5g in Releases 15 and 16 and beyond The 3GPP timeline is shown in Figure 1.1 3GPP Roadmap 20152016201720182019202020212022 ★ ★ REL 13 REL 14 REL 15 REL 16 WID Rel15 SA2 Archltecture study S 5G RAT features will be phased as RAN RAN Study WID it will not be possible to standardize all in time for Te1-15 Relic completion and early SA1 Requirement Stud deployments S Release 15 will aim at a first SAZ Architecture Study WID phase of expected deployments RAN RAN Stucy in2020 A Release 16 will target the ITU IMT-2020 submission Figure 1.1. 3GPP Timeline Releases 13 to 16. 2. GLOBAL MARKET TRENDS, MILESTONES AND STANDARDIZATION By the end of March 2018, nearly 40 percent2 of the 7. 5 billion people worldwide had access to a Fourth Generation Long Term Evolution(4G LTE) network, providing them with high-speed services and applications including mobile internet. Global LtE coverage stood closer to 44 percent by the end of the 1Q2018 Ovum.

The shift from 2G is evident; some service providers(e. g at&t) have sunset their 2G networks (2017)to properly plan in areas such as Machine-to-Machine(M2M) communications and other connected devices. The need for service providers to sunset their networks weighs heavily on their available spectrum assets reframing their spectrum and getting the best efficiencies by using more advanced 4G technology in those limited spectral resources 3 Worldtimezone. com, August 2018 December 2017 GSM HSPA HSPA GSM Q42017 Q42022 SHARES SUBS TECH SHARES SUBS 30% 3.1 B HSPA2.9B31% 1% 104 M TD-SCDMA 1% 23%230 M CDMA56M0.6% LTE 31. 8% 2B LTE 4.9B53% LTE 35%31BGsM955M10% Figure 2.2.
