Narrow Band-Physical Broadcast Channel (NPBCH)

January 31, 2019

NPBCH stands for narrowband physical broadcast channel similar to PBCH in LTE Technology. The Narrow Band-Physical Broadcast Channel (NPBCH) is used to deliver the NB-IoT Master Information Block (MIB), which provides essential information for the NB-IoT UE to operate in the NB-IoT network. Narrow Band-Physical Broadcast Channel (NPBCH) uses a 640 ms TTI, but within […]

Narrow Band Synchronization Signals (NPSS and NSSS)

January 31, 2019

The NPSS and NSSS help UE to synchronize downlink to an NB-IoT cell. These are transmitted in certain subframes based on an 80-ms repetition interval. By synchronizing to NPSS and NSSS, the device will be able to detect the cell identity number (NB-IOT PCI). NPSS and NSSS are designed to allow devices to use a […]
