Narrow Band-Physical Broadcast Channel (NPBCH)

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…
