full_form: Narrow Band Internet of Things
context: Summary based on the input provided by Huawei, HiSilicon in RP-220530. This Rel-17 work item introduced additional enhancements for NB-IoT and LTE-MTC based on features standardized in Rel-13 and enhancements performed from Rel-14 through Rel-16. Rel-17 adds features such as 16QAM for NB-IoT in downlink and uplink, 14 HARQ processes in downlink for HD-FDD Cat. M1 UEs, NB-IoT neighbour cell measurement and triggering before RLF, NB-IoT carrier selection based on coverage level, and a maximum DL TBS of 1736 bits for HD-FDD Cat. M1 UEs [1]. 16-QAM for unicast in UL and DL for NB-IoT From Rel-13 to Rel-16, an NB-IoT UE can use QPSK for unicast NPDSCH, and QPSK or BPSK for unicast NPUSCH. This feature allows an NB-IoT UE to use 16-QAM for unicast NPDSCH with TBS up to 4968 bits for standalone and guard-band deployments and 3624 bits for in-band deployments; and allows an NB-IoT UE to use 16-QAM for unicast NPUSCH with TBS up to 2536 bits (which can be transmitted with up to half the
description: Narrow Band Internet of Things (NB-IoT) is a technology standard for low-power, wide-area networks (LPWANs), designed for machine-to-machine (M2M) and internet of things (IoT) applications. It operates on a narrow band of spectrum, typically using existing LTE infrastructure, to provide efficient and cost-effective connectivity for devices that require low bandwidth and long battery life.
explanation: The context describes NB-IoT as a technology standard with specific functionalities like operating on a narrow band of spectrum and utilizing existing LTE infrastructure. This points towards it being a technological advancement rather than a concept in other domains.
