Method for receiving system information in wireless communication system that supports narrowband iot and apparatus for the same

A terminal for receiving system information in a wireless communication system supporting a narrowband (NB)-Internet of Things (IoT), comprising:

• a Radio Frequency (RF) unit for transmitting and receiving a radio signal;
• and
• a processor for controlling the RF unit,
• wherein the processor is configured to perform:
• receiving a narrowband synchronization signal (NBSS) through a narrowband (NB) from a base station;
• acquiring, based on the NBSS, time synchronization and frequency synchronization with the base station;
• and
• receiving the system information related to the NB-IoT through a narrowband physical broadcast channel (N-PBCH) from the base station,
• wherein the system information includes at least one of operation mode information indicating an operation mode of the NB-IoT system or control information indicating an index of a legacy CRS (cell-specific reference signal) sequence, and
• wherein the control information is associated with a PRB (physical resource block) index of a PRB to which the legacy CRS is transmitted.
