5G in reality technology Workshop

Gábor Soós, TU – CNDC, Magyar Telekom 25. April 2017

Service providers for customer needs

Digitalization Innovation 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

IMT-2020 for 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!

<6GHz

>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)

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)

•RaaS

•EPCaaS

•NFV

•SDN

•CaaS

Virtualization of the network - ongoing

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

Summarised

5G

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 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
