NB-IOT UE Attach Call Flow Messaging

When a NB-IOT UE accesses a cell, it follows the same principle as for LTE: It first searches a cell on an appropriate frequency. Decode NPSS and NSSS for NCellID. […]

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 […]
