Abstract

Narrowband Internet of Things synchronization signals are described that carry offset information. In one example an evolved NodeB (eNB) to performs operations to transmit synchronization signals for time and frequency synchronization between the eNB and user equipments (UEs) for narrowband Internet of things (NB-Iot). The operations include concatenating a plurality of short ZadoffChu (ZC) sequences each having a different root index, the ZC sequences being ordered to indicate an offset for use by a UE, generating an NB-Iot Primary Synchronization Signal (NB-PSS) using the concatenation of short ZadoffChu (ZC) sequences, and transmitting the resulting NB-PSS by the eNB in a periodic manner to the UE, wherein, the offset is identified by the order of the ZC sequences.
