name: NB-IoT
full_form: NarrowBand Internet of Things
context: For NB-IoT co-existence with NR, 3 system scenarios have been studied: NB-IoT operation in NR in-band, NB-IoT operation in NR guard band and NB-IoT standalone operation. For NB-IoT operation in NR in-band, RB alignment, power boosting and numerologies have been addressed. NB-IoT and NR operating with 15 kHz SCS could coexist in NR band while optimizing resource utilization by aligning respective RBs. And similar as NR, no requirement on mixed numerology is defined for coexistence between NB-IoT and NR. For NB-IoT operation in NR guard band, the refarming scenarios have been considered and it is concluded that even if one NB-IoT 15 kHz sub-carrier would operate in NR guard band, still consider this case as NB-IoT operation in NR in-band. NB-IoT operating in NR guard band would mean revisiting agreed spectrum utilization in Rel-15, which would be too early. RF requirements will not be specified in Rel-15 (nor in Rel-16 unless new Rel-16 features make this essential). For NB-IoT
description: NarrowBand Internet of Things (NB-IoT) is a technology standard for low-power, wide-area networks used for machine-to-machine communication and the Internet of Things. In the context of 3GPP specifications, NB-IoT co-existence with New Radio (NR) has been studied in various scenarios, including operation in NR in-band, guard band, and standalone operation.
explanation: The text describes NB-IoT as a technology standard defined within 3GPP specifications. It outlines its purpose for low-power wide-area networks and applications like machine-to-machine communication and the Internet of Things. The discussion of co-existence with New Radio (NR) further solidifies its classification as a technological concept.
