Fecha de publicación: 15/02/2018 Fuente: Wipo "IOT" A method for user equipment (UE) to receive a reference signal in a cellular mobile communication system supporting narrowband-Internet of Things (NB-IoT) is disclosed. To this end, the UE receives, via at least one first subframe, a narrowband reference signal (NRS) for signal demodulation or measurement in NB-IoT and receives, via at least one second subframe, a narrowband positioning reference signal (NPRS) for location-based measurement in the NB-IoT, wherein information on the at least one second subframe is received from a base station as configuration information of the NPRS, and, in accordance with the configuration information of the NPRS, the UE operates by assuming that the NRS is not transmitted in a subframe configured with the second subframe.
