METHOD FOR TRANSMITTING OR RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM SUPPORTING BAND OF 6GHZ OR LOWER, AND DEVICE THEREFOR

摘要

The purpose of the present specification is to provide a method for transmitting or receiving a signal in a wireless communication system supporting a band of 6GHz or lower. To achieve the purpose provided in the present specification, the present specification provides a method performed by a terminal, the method comprising the steps of: receiving a synchronization signal (SS) from a base station in a specific subframe; acquiring time synchronization and frequency synchronization with the base station on the basis of the synchronization signal, and detecting an identifier of the base station; and receiving a physical broadcast channel (PBCH) from the base station in the specific subframe on the basis of the detected identifier of the base station, wherein a first synchronization signal and a second synchronization signal are received in different frequency bands of the specific subframe, and the synchronization signal and the PBCH are received in different symbols of the specific subframe. Therefore, the method can reduce the size of a minimum system bandwidth of a corresponding system.
