Abstract
A method for improving reliability of a narrowband physical broadcast channel (NPBCH) reception in narrowband internet-of-things (NB-IoT) user equipment (UE) during a cell acquisition phase. An object is to improve the existing NPBCH reception procedure in order to achieve a lower code-rate and hence a more reliable transmission between eNodeB and UEs will be solved thereby that the UE receives, descrambles and de-rate-matches at least a first and a second group of 64 NPBCH subframes, whereas using the four most significant bits of the system frame number as a counter and a modifier sequence {m}, which is applied to the first group of 64 NPBCH subframes, before combining the both groups, decoding and extracting the master information block from the combined NPBCH subframes and whereas the UE attaches to the cell if a match is found.
