What and Why?

NB-IoT (Narrowband Internet of Things): a new LTE-based narrowband radio technology to address requirements of IoT

NB-IoT perfectly matches LPWA (Low Power Wide Area) market requirements as it• Reduces IoT device complexity

• Enables multi-year battery life

• Guarantees 20+ dB coverage (to reach challenging locations such as deep inside buildings)

• Provides 1000x connections

• Leverages existing LTE infrastructure and spectrum

• Coexists with today’s mobile broadband services

Many mobile operators have set up dedicated IoT/M2M business units in order to serve the growing number of market requirement




Use Cases

2 Personal Wearables, Smart bicycle, Kids monitoring, Pet tracking

3 Public Smart garbage bin, Smart meter, Street light, Alarms & Event Detector

4 Industry Asset tracking, Logistics tracking, Alarms & Event Detectors

NB-IoT Target Low-end

“Massive MTC” Scenario

use cases can be different per operator, country and region or per addressed market

MTC (Machine-Type Communications) Scenarios




Design Targets

Cost (low device cost/complexity): < $5 per module• Solutions: Reduction of maximum B/W, supported DL transmission modes (TM), transmit power

Power (low device power consumption): > 10-year battery life• Solutions: Extended DRX (eDRX) cycle in IDLE & CONNECTED mode, Power Saving Mode (PSM), Reducing RF Bandwidth

Coverage (extended coverage): 164 dB MCL, 20 dB better compared to GPRS• Solutions: Repetitions, TTI Bundling Enhancement, PSD Power Boosting

Capacity (massive number of low throughput devices): 40 devices/house, i.e. ~55k devices per cell

Latency (uplink report latency): < 10 secondsNote

Coupling Loss: total channel loss over the link between UE antenna ports and eNB antenna ports, including path loss

MCL (Maximum Coupling Loss): limit value of coupling loss at which service can be delivered and defines the coverage of the service




Standardization: Why?

3GPP has standardized NB-IoT (Rel-13) in 22 June 2016!

Advantages of NB-IoT being part of 3GPP SDO?

3GPP provides superior solution to emerging non-3GPP technologies for IoT LPWA applications. The benefits includes

Ubiquitous coverage: leverage existing LTE networks (~500 networks) in 160+ countries, leading to fast development, economies of scale, and global roaming

Scalability: part of a unified platform that can scale from 10s of kbps to Gigabit-Class LTE, enabling large-scale deployments

Coexistence: compatible with existing LTE networks, spectrum, and services

Software-powered: can be deployed as a simple addition of new software to existing LTE infrastructure

Managed Quality of Service (QoS): utilize licensed spectrum for guaranteed resource allocation

End-to-end Security Framework: established/trusted state-of-the-art security and authentication features

Feature Growth: seamless for future MBB and NB-IoT use cases




Network Deployment

Stand-alone operation• Utilizes new bandwidth (e.g. refarm GSM carrier

at 850/900 MHz)

Operation in LTE “Guard Band”• Use bandwidth reserved in guard band of

existing LTE network

“Inband” Operation within wider LTE carrier• Use of same resource block (PRB) in LTE

carrier of existing LTE network

Stand-alone and Guard Band deployment options tend to offer best performance in terms of improved indoor coverage, FDMA (GMSK) also offers about 20% power consumption saving and lower cost

3 Deployments Modes




System Architecture

NB-IoT Architecture: based on LTE

Core: EPC (Evolved Packet Core)

Mobile Terminal: CIoT UE (Cellular IoT User Equipment)

Radio Access: E-UTRAN (evolved UMTS Terrestrial Radio Access Network) handles the radio communications between the CIoT UE & EPC

Authentication, Signaling & Security: same as normal LTE as such security supporting optimized transmission of user data• Encrypted and integrity protected user data can be sent within NAS signaling

• Minimized signaling to resume cached user plane security context in the radio network

NB-IoT Enhancements

Further enhancements for NB-IoT (& eMTC) are being worked on for next 3GPP Release (Rel-14). It includes

Positioning

Multicast• Support multi-cast downlink transmission (e.g. firmware or software updates, group message delivery)

for NB-IoT

Non-Anchor PRB enhancements

Mobility and service continuity enhancements

New Power Class(es)• Evaluate and, if appropriate, specify new UE power class(es) (e.g. 14dBm), and any necessary

signaling support, to support lower maximum transmit power suitable for small form-factor batteries, with appropriate MCL relaxations compared to Rel-13




Positioning

Background UE positioning and tracking are important in many IoT applications, such as asset tracking

Motivation GNSS-based positioning method is not appropriate for many IoT applications

In Rel-13, only limited positioning functionalities are provided for eMTC and NB-IoT UEs

Need Improvements of the 3GPP positioning methods are necessary to support a competitive 3GPP-based IoT eco-system

Solution For eMTC positioning support, define

• OTDOA: RSTD measurements and reports based on legacy PRS

• E-CID: RSRQ, and UE Rx – Tx time difference

For NB-IoT and eMTC improved positioning accuracy, define • New DL reference signal or configuration

• New UL signal or configuration to improve UL timing estimation accuracy

Define corresponding signaling changes• LPP

• RRC and LPPa

Proposal: Ericsson (RP-160878, 3GPP TSG RAN Meeting #72, Busan, Korea, June 13 - 16, 2016)




Multicast

Background eMBMS was developed to efficiently deliver multicast services over areas typically spanning multiple cells. But there could be a

number of applications that may benefit from efficient multicast service support over a single cell

Motivation When many devices need to receive same information simultaneously, e.g. in case of rollout of firmware or software upgrades,

it is in many cases more efficient to use multicast transmission instead of unicast transmission

eMBMS transmission based on Single-Cell Point-To-Multipoint transmission (SC-PTM), based on LTE downlink shared channel, was developed for eMTC & NB-IoT (Rel-13)

Need Enhanced low complexity multicast/broadcast functionality in normal and enhanced coverage for eMTC & NB-IoT devices

Solution Form of a narrowband format of regular MBSFN transmission functionality

Small extension of the recently introduced (SC-PTM) functionality.

Proposal: Ericsson (RP-160878, 3GPP TSG RAN Meeting #72, Busan, Korea, June 13 - 16, 2016)
