The present invention provides a method for detecting an uplink synchronization signal in a wireless access system supporting a high-frequency band, a method for designing a detection filter for the same and an apparatus for supporting the same. According to one embodiment of the present invention, a method for detecting a random access channel (RACH) signal by a base station in a wireless access system supporting the high-frequency band comprises the steps of: allocating a cyclic shift value used in the base station; configuring a received signal vector for a signal transmitted via a random access channel; detecting at least one RACH signal from the received signal vector, using a frequency domain detecting (detection) filter; and identifying at least one terminal having transmitted at least one RACH signal, using a target terminal detecting (detection) filter, wherein the filter for detecting a target terminal may be set on the basis of the cyclic shift value. |
