Abstract: Provided are a method and an apparatus for obtaining downlink synchronization in a wireless communication system. The wireless communication system that is proposed has an environment in which the resource location of a downlink synchronization signal changes due to the application of multiple numerology. Particularly, a terminal receives synchronization signal information from a base station. The synchronization signal information includes candidate resources from which synchronization signals with respect to a tracking area can be transmitted, and the order of detecting the synchronization signals from the candidate resource win respect to the tracking area. The terminal detects the synchronization signal on the basis of the synchronization signal information.
