A method of detecting a location of a subscriber station in a separated-type radio access station, the subscriber station connected with the separated-type radio access station, wherein the method comprises receiving power spectrum information for an uplink frame from a remote unit; obtaining identification information for a sub-carrier corresponding to a frequency whose power value is higher than a reference value from the power spectrum information; and determining that the subscriber station is located within a coverage area of the remote unit when it is detected with reference to mapping information for the sub-carrier allocated to the subscriber station that the subscriber station is mapped to the identification information.
