    摘要: The present invention relates to an access method for solving ambiguity between an initial access mobile station and a base station, wherein the ambiguity occurs in a carrier aggregation environment. When a base station transmits a downlink message including different downlink ID information through plural downlink carriers, a base station obtains the corresponding downlink ID information through a downlink carrier used by the mobile station. The mobile station transmits an uplink message using the obtained downlink ID information, and the base station extracts the downlink ID information from the uplink message in order to confirm which downlink carrier the mobile station uses.
