Abstract: The present invention relates to a method for newly defining a synchronous signal used in a super-high frequency band and acquiring downlink synchronization by using the synchronous signal, and an apparatus for supporting the same. The method for enabling a base station to transmit the synchronous signal in the wireless access system supporting the super-high frequency band, as one embodiment of the present invention, comprises the steps of: generating a general synchronous signal which do not have repetitive characteristics; generating a repetitive synchronous signal on the basis of a repetition factor for estimating a carrier frequency offset of the super-high frequency band; transmitting the general synchronous signal from a first frame; and transmitting the repetitive synchronous signal from a second frame. At this time, the repetition factor indicates the repetitive characteristic of the repetitive synchronous signal.
