full_form: Narrowband Primary Synchronization Signal
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: The Narrowband Primary Synchronization Signal (NPSS) is a specific channel in the Narrowband Internet of Things (NB-IoT) downlink carrier, used for synchronization purposes. It is transmitted in downlink subframes configured by higher layer parameters such as nprsBitmap, and its transmission is subject to certain rules and restrictions, including not being mapped to resource elements allocated to other channels or system information blocks.
explanation: NPSS is classified as a Channel because it refers to a specific path for data transmission in the NB-IoT downlink carrier, used for synchronization purposes. The provided context from 3GPP TS 36.211 describes the configuration and transmission rules of NPSS, highlighting its role as a distinct channel within the NB-IoT system.
