    Abstract: In the transmission of user data for a user equipment and control information on the user data to the user equipment using a plurality of carrier waves by a base station in a wireless communication system, the control information can be transmitted over a portion of the plurality of carrier waves, and carrier waves over which only the user data is transmitted can be generated without the control information. Here, the base station transmits, at a certain number of subframes following the subframes at which the control information is transmitted, the user data over the carrier waves to which only the user data is allocated. Thus, the user equipment can minimize the buffering of the user data during the detection of the control information, and decode the user data.

    Abstract: The present invention relates to a method and apparatus for generating a reference signal sequence in a wireless communication system. User equipment receives a cell-specific sequence hopping parameter from a base station, receives, from the base station, a user equipment (UE)-specific sequence group hopping (SGH) parameter which is specific to said user equipment, and generates a reference signal sequence on the basis of a base sequence number of a base sequence, wherein the base sequence number is determined for each slot on the basis of the cell-specific sequence hopping parameter and of the use equipment-specific sequence group hopping parameter. Here, the determination of whether or not to apply sequence hopping to the base sequence number indicated by the user equipment-specific sequence group hopping parameter overrides that of whether or not to apply sequence hopping to the base sequence number indicated by the cell-specific sequence hopping parameter.
