5G in reality technology Workshop Gábor Soós, TU CNDC, Magyar Telekom 25. April 2017
Service providers for customer needs IMT-2020 for customers Innovation Digitalization Simplify Support legacy systems Deploy innovative Software services (SDN) for enterprise and customer SP must realize, 5G is a shift to cloud services Want to Virtualize (Network function), automate, and simplify Customers with less needs and efforts must be served as well as new customers
As of today 2G, 3G and 4G are separated, they are not fully converged UNTIL THE NEW PACKAGE represents A DIFFERENT QUALITY IT IS ONLY BUNDLING! 3
Providing Seamless, integrated customer experience could be a real differentiator factor in the market TO WIN CUSTOMERS 5G VISION SEAMLESS, INTEGRATED CEX ANYWHERE, ANYTIME, ANYHOW Common freq. range, Less complexity Flexible access technology with software define services Larger capactity, higher speed, less expenses Automatic optimization (SON) Less consumption, better efficiency 4

<6GHz: LTE compatible; >6GHz: 5G <6GHz LTE-A Carrier aggregation (maxi 5x20MHz: 750Mbps), Evolved MIMO (maximum 8x8: 3Gbps) LTE-M/NB-IoT (1,4MHz /180-200kHz) LTE-Direct (Direct communication between UEs) LTE-x LAA (License Assisted Access: 5GHz ISM band) Dual Connectivity (use more radio access types simultaneously) Mass MIMO (>8x8; Antenna Beam forming) >6GHz 5G Full duplex (same time DL and UL communication) Virtualized RAN and services (cloud based network, RAaaS, EPCaaS) New type radio access (better frequency efficiency, low latency, low power consumption) Biztonsági konferencia 9
Virtualization of the network - ongoing RaaS EPCaaS NFV SDN CaaS 09/2016 10
Bonding at IP layer, mobile and WiFi - ongoing MPTCP v0.91 & 0.92, SCTP, QUICs More than 1 radio interface is ON Bonding licensed and unlicensed spectrum at RAN or IP level Operating Modes: Full MPTCP, Backup Mode, Single-path 11
Narrow Band-Internet of things High level expectations 12
NB-Iot, a technology living on 4G - ongoing Status: Existing, Global 3GPP standard (R13) GSM: 200kHz, LTE: 180kHz Modulation: QPSK Expected: 20M devices till 2020 in Hungary (NMHH) Software function based on 3GPP R13: edrx (Extended idle-mode Discontinuous Reception) e-t3412 be offline from weeks to years Deep indoor coverage with software modification (+20dB) IPv4-IPv6, Data over NAS, NIDD 13
Summary, key takeaway What will 5G give to the customers? Multi-hop communication Device-to-device and cooperative devices Ultra-liable, multi-band networks Ultra dense deployment Massive machine to machine services 5G standardization: Below 6 GHz for LTE-A and LTE++, above 6 GHz for 5G Investigation of different type aggregation (radio, IP, FIA IP+) NB-IoT is under plan in 2017+ Architecture is under industry consensus, specification is still ongoing Acceleration has been issued for proper IMT-2020 compatible NR 14

3GPP - 5G Architecture Requirements (3GPP TR23.799 V0.5.0 (2016-02) Summarised 1. Support existing and new RAT(s), the Evolved E-UTRA 2. Simultaneous access to multiple RATs 3. Non - 3GPP access types - WLAN access and Fixed access supported 5G 4. Unified authentication framework for different access systems 5. Flexible architecture with auto-scale (In/Out), network sharing, multicast/broadcast 6. Separation of Control plane and User plane functions 7. Optimised mechanisms to control and avoid signalling congestion 8. Leverage techniques NFV/SDN, network Softwarisation and slicing 9. UE maintains simultaneous connections to multiple access technologies 10. Large number of UEs in periods without data traffic (Needing enhanced mobility management) 11. Efficient content delivery - Support IP packets, non-ip PDUs and Ethernet frames Biztonsági konferencia 17 17
