Abstract: A method and an apparatus for generating a synchronization signal in the Internet of things. In the method for generating a synchronization signal, subcarrier mapping may be performed by exchanging a signal allocated to an upper subcarrier group and a signal allocated to a lower subcarrier group among all subcarriers allocated for the synchronization signal with each other, in an in-band operation mode or a guard band operation mode of the Internet of things.
