The present specification provides a method for obtaining downlink synchronization in a machine type communication (MTC) apparatus. The MTC apparatus may comprise the steps of: receiving an MTC-dedicated synchronization signal from a base station on the subframe before a subframe which attempts to receive a paging message; obtaining a downlink synchronization of the base station through the synchronization signal; and after obtaining the downlink synchronization, attempting to receive the paging message. Here, the MTC-dedicated synchronization signal may be received on the same sub-band as a sub-band on which the paging message is received, from among the entire system band of the base station.
