Abstract
Embodiments of the present disclosure describe systems, devices, and methods for channel estimation for NB-PBCH in NB-LTE systems. Various embodiments may relate to options that can be used for demodulation of the NB-PBCH by the NBLTE-UEs, and in certain embodiments may include a reference signal (RS) usable for demodulation of the NB-PBCH by the NBLTE-UEs. Other embodiments maybe described or claimed.
Claims1
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 often 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.
