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.

Broadcast channel reception in NB-IoT devices

The application relates to a method for reducing false positive detection in NB-IoT downlink control channel. The method comprises the following steps: synchronizing a UE to an eNB and exchanging a data transmission via a NPDSCH or a NPUSCH, whereas DCI pertaining to downlink or uplink data transmission is signaled to UE by eNB via NPDCCH, wherein calculating an effective code rate of NPDCCH that is used in receiving downlink grant, resulting in a value CR, calculating a scheduled code rate of NPDSCH or NPUSCH, resulting in a value CRor CR, calculating a ratio between the effective code rate CRand the scheduled code rate CRor CR, resulting in a result x, comparing the result x with pre-defined upper and lower bounds, dropping and not processing further the result x as false positive detection if the result x violates the pre-defined bounds.

A method for handover in a mobile communication system, wherein cell search is performed by determining cell identities based on cell identity information transmitted within downlink data is provided. The cell power of cells detected by cell search is measured. Moreover, the cell power of an additional cell is measured, the additional cell having a cell identity that is related to a cell identity of a cell detected by cell search in that the additional cell and the cell detected by cell search are adjacent cells. The method is applicable in cross-sector scenarios avoiding call drops due to lengthy cell detection.
