NR-Lite, formally introduced during the 3GPP Release-17 study at Newport Beach in June 2019, aims to support low-tier 5G user equipment and various IoT applications that require higher data rates and lower latency compared to existing standards. The new feature promotes system efficiency by enabling operators to migrate their networks to NR and leverage advanced capabilities such as beamforming and better battery life. NR-Lite addresses the connectivity necessitated by diverse industrial verticals while simplifying network architecture, enabling a single network to support multiple use cases.
![Nokia: NR-Lite in Rel-17
•NR-Lite should address new use cases with IoT-type of requirements that cannot be met by eMTC and NB-IoT:
•Higher data rate & reliability and lower latency than eMTC& NB-IoT
•Lower cost/complexity and longer battery life than NR eMBB
•Wider coverage than URLLC
•Requirements and use cases –
•Data rates up to 100 Mbps to support e.g. live video feed, visual production control, process automation
•Latency of around [10-30] msto support e.g. remote drone operation, cooperative farm machinery, time-critical
sensing and feedback, remote vehicle operation
•Module cost comparable to LTE
•Coverage enhancement of [10-15]dB compared to URLLC
•Battery life [2-4X] longer than eMBB
•Enable single network to serve all uses in industrial environment
•URLLC, MBB & positioning

- 13. Different types NR-Light UEs / Devices ©3G4G • IWSN: Industrial wireless sensor networks • Examples: microphones, CO2 sensors, pressure sensors, humidity sensors, thermometers, cameras, video cameras, motion sensors, accelerometers, laser scanners, fluid-level sensors, inventory sensors, electric voltage meter, electric current meter, actuators • Wearables • Low-end Wearables • Relaxed-IoT • Different Terminology for NR-Lite being used: • Low tier 5G UEs • IWSN & mid-end IoT
- 14. NR-Lite vs LTE Why introduce NR-Lite instead of reusing LTE? •Motivation •No need to support 3 different networks –NR, eMTC/NB-IoT, and LTE •Operators can migrate their spectrum to NR which can support both URLLC & NR-Lite on the same carrier as well as deploy eMTC/NB-IoT either in-band or in guard-band. •Better system efficiency with NR compared to LTE •Utilize NR features like beam-formed operation, higher subcarrier spacing for latency reduction, massive MIMO for coverage, mixed numerology, higher positioning accuracy, low-overhead carriers, etc. •Deploy URLLC & NR-Lite in also FR2 and new spectrum •FR2 can be very attractive for private networks due to its limited range and high spatial reuse e.g. each building or floor can have its own network and they will not interfere with each other •Better integration and benefits from 5G core and architecture –network slicing, service based architecture, flow-based QoS, etc. ©3G4G
