1. An apparatus, comprising:

  • radio frequency (RF) circuitry to receive a synchronization signal including at least one of a Narrowband Primary or Secondary Synchronization Signal (NB-PSS or NB-SSS);

    baseband circuitry to identify channel estimates corresponding to a first subframe of the synchronization signal adjacent to a second subframe carrying Narrowband Physical Broadcast Channel (NB-PBCH), wherein a location of the first subframe within a set of ten consecutive subframes of a Long-Term Evolution (LTE) radio frame is cell-specific based on a Physical Cell Identity (PCID) of a transmitting cell and the set of ten consecutive subframes of the LTE radio frame spans a duration of 10 milliseconds (ms); and

    the baseband circuitry to use the identified channel estimates to recover the NB-PBCH.
