    摘要: Provided are a method for receiving information on a relay node zone and reference signals for a relay node from a base station, and a relay node device using same. The relay node can receive information on at least one start point from the start points of a Relay-Physical Downlink Control Channel (R-PDCCH) and a Relay-Physical Downlink Shared Channel (R-PDSCH) for transmitting a signal from a base station to a relay node in a specific downlink subframe. Alternatively, the relay node can implicitly recognize the start points of the R-PDCCH and R-PDSCH set in advance. The relay node can recognize a signal from the base station in the specific downlink subframe based on the start point information after the time corresponding to at least one of the start points of the R-PDCCH and R-PDSCH. Also, the relay node can decode signals transmitted from a base station after the corresponding timing.

    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.
