NB-IOT Synchronization Signals (NPSS and NSSS)

The NPSS and NSSS helps 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 […]

NB-IOT – 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 […]
