    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.

    摘要: Disclosed are a method and a device for performing HARQ in a multiple antenna system. A terminal transmits uplink data via a plurality of antennas and through a Physical Uplink Shared Channel (PUSCH), and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal indicating whether or not the uplink data has been received, the signal being received via the plurality of antennas and through a PHICH (Physical Hybrid-ARQ Indicator Channel) which corresponds to the PUSCH. A downlink resource to which the PHICH is mapped is determined on the basis of the index (IPRB—RAlowest—index) of the smallest Physical Resource Block (PRB) among the PRBs to which the PUSCH is mapped, uplink DMRS (Demodulation Reference Signal) cyclic shift parameters (nDMRS) and Orthogonal Code Cover (OCC) index.
