name: NB
full_form: NarrowBand
context: On a NB-IoT DL carrier configured for NPRS transmission, an NB-IoT UE can assume NPRSs are transmitted in DL subframes configured by all higher layer parameters nprsBitmap, the NB-IoT carrier-specific subframe configuration period the NB-IoT-carrier-specific starting subframe offset and the number of consecutive downlink subframes where NPRS shall be transmitted. If frame structure type 2 is used, the UE shall not assume NPRSs are transmitted in special subframes. - If , and are not configured for an NB-IoT downlink carrier configured for NPRS transmission, an NB-IoT UE shall assume NPRSs are transmitted in downlink subframes configured by higher layer parameter nprsBitmap. - If nprsBitmap is not configured for an NB-IoT downlink carrier configured for NPRS transmission, an NB-IoT UE shall assume NPRSs are transmitted in downlink subframes configured by the higher layer parameters , and . - If the higher layer parameter operationModeInfoNPRS for the configured NB-IoT carrier is set to in-band, the higher layer parameters nprsBitmap shall be configured. - If , and are configured, the NPRS instances in the first subframe of the downlink subframes, shall satisfy . The NPRSs shall not be mapped to resource elements allocated to resource blocks of NPBCH, NPSS, NSSS, or SystemInformationBlock-Type1-NB regardless of their antenna port .
description: NarrowBand (NB) refers to a technology standard in the context of Narrowband Internet of Things (NB-IoT), which is a cellular communication standard for low-power wide-area networks (LPWANs). NB-IoT operates on a narrowband spectrum, typically using a single or a few resource blocks within a LTE carrier. The technology is designed to support IoT applications that require low bandwidth and power consumption, such as smart metering, industrial automation, and environmental monitoring.
explanation: NB is classified under the Technology category because it represents a specific standard for telecommunications operations, particularly in the context of IoT communications. The provided context highlights the technical specifications and configurations related to NB-IoT, such as NPRS transmission, subframe configuration, and resource allocation, which are all relevant to the technology's implementation and operation.
