Abstract: 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 devices for supporting the methods. A method by which a base station detects a random access channel (RACH) signal in a wireless access system supporting a high frequency band, according to one embodiment of the present invention, comprises the steps of: allocating a cyclic shift value used in the base station; configuring a reception signal vector for signals transmitted through the RACH; deriving a cyclic shift candidate greater than or equal to a reference value from the reception signal vector by using a first detection filter; and detecting the RACH signal from the cyclic shift candidate by using a second detection filter, wherein the first detection filter and the second detection filter can be set on the basis of the cyclic shift value.
