Path to 5G (Don’t Forget LTE-Adv.)

Pre-Deployment 5G Industry Expectations

LTE-Advanced Evolution (R13&14) • FD-MIMO

• Improved densification management

• Dual connectivity

• Improved latency

• Higher order modulation

• Virtualization

Narrowband LTE

• Designed for low-power devices, with 10-year battery life

• Standards this summer; deployment late 2017 / early 2018

So much more than speed

• Multi-gigabit speeds and high capacity • Connectionless Massive IoT • Ultra-Low Latency and high reliability • Sub 6 GHz for wide area coverage with

improved spectral efficiency • Flexible, lean carrier design • Multi-RAT network using sub 6 GHz,

mmWave and unlicensed bands in concert • Massive MIMO • Densification with self-backhaul • SDN/NFV based architecture

ATIS 5G Workshop 2016

6

New Frequency Regimes

• Sub 6 GHz

• Wider bandwidth

• CA at layer 1

• IoT optimization

• mmWave • New propagation characteristics

• Extremely wide channels

• New channel models

• New interference analysis, coordination, and mitigation

• Channel sounding needed in multiple parts of the world

New 5G Core Network

• Core Needs • Low end-to-end latency

• Diverse and highly varied requirements

• Flexibility in network design and operations (it needs to do the splits too)

• Key Enablers • Virtualization – NFV

• SDN – software centric control

• Open source (OpenDaylight, OpenStack, OPNFV, ON.lab, Linux Foundation, etc.)

• Big Data

• “Network Slicing”
