7 NB-IoT (3GPP Rel-13) 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 Slide 7

9 NB-IoT (3GPP Rel-13) 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 seconds Note 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 Slide 9

10 NB-IoT (3GPP Rel-13) 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 largescale 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 Slide 10

11 NB-IoT (3GPP Rel-13) Network Deployment 3 Deployments Modes 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 Slide 11

12 NB-IoT (3GPP Rel-13) 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 Slide 12

14 NB-IoT (3GPP Rel-14) 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 Slide 14

15 Background NB-IoT (3GPP Rel-14) Positioning 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 , 3GPP TSG RAN Meeting #72, Busan, Korea, June 13-16, 2016) Slide 15

16 Background NB-IoT (3GPP Rel-14) Multicast 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.
