Narrow Band-Physical Broadcast Channel (NPBCH)

NPBCH stands for narrow band physical broadcast channel similar to PBCH in LTE Technology. The 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. NPBCH uses a 640 ms TTI, but within the TTI only subframe 0 is used in every radio frame. NPBCH is transmitted in entire subframe zero of a radio frame (except initial 3 OFDM symbols). Subframe Location: 0 Subframe periodicity: 10 ms Basic TTI 640 ms NPBCH Channel Characteristics. NPBCH...
