Abstract:
Systems and methods for configuring Narrowband Positioning Reference Signals (NPRS) for NB-IoT are provided. A network node generates and transmits NPRS configuration information including a first NPRS bitmap for FDD mode and/or a second NPRS bitmap for TDD mode. A wireless device can determine a NPRS configuration in accordance with the second NPRS bitmap for TDD mode and perform measurements using the NPRS configuration.
