    Abstract: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and to an apparatus for transmitting an SRS in a multi-antenna system. The method comprises the steps of: acquiring specific information for discriminating a first antenna group and a second antenna group from among a plurality of antennas, wherein said first antenna group includes one or more antennas which are set to a turned-on state to perform communication with a base station, and said second antenna group includes one or more other antennas which are set to a turned-off state; transmitting an SRS to the base station if a predetermined condition is satisfied, under the condition that the second antenna group is set to the turned-off state; and setting the second antenna group to a turned-off state after the transmission of the SRS.

    Abstract: A method is provided for demodulating a signal. A relay node receives control information, from an evolved-NodeB (eNB), through a relay-physical downlink control channel (R-PDCCH), and receives a data, from the eNB, through a physical downlink shared channel (PDSCH). When a number of transmission layers of the PDSCH is 2 or more than 2 and a plurality of reference signals for a demodulation of the data are transmitted on antenna ports by the eNB, a reference signal transmitted on a minimum antenna port among the antenna ports is used for a demodulation of the control information.

    Abstract: A method is provided for transmitting, by a base station, signals in a communication system. Carrier aggregation configuration information is transmitted to a mobile station via a primary carrier band of the mobile station. The carrier aggregation configuration information informs the mobile station of a subsidiary carrier band for the mobile station. Uplink control information for the subsidiary carrier band is received from the mobile station via the primary carrier band. The carrier aggregation configuration information includes a physical identification of a frequency allocation band used as the subsidiary carrier band and a logical identification assigned to the subsidiary carrier band for the mobile station. The physical identification includes one of plural absolute frequency band indexes assigned to frequency allocation bands available in the communication system. The logical identification includes a logical index assigned to the subsidiary carrier band identifying the subsidiary carrier band.

    Abstract: A method is provided for performing a random access procedure by a Node-B with a specific user equipment (UE) within a cell in which a plurality of UEs are located together. The Node-B transmits a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration. The Node-B receives a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel. A length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration. The random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.
