Abstract
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.
