    Abstract: A method for a base station to receive an uplink transmission from a user equipment configured with multiple uplink component carriers in a wireless communications system. The method according to one embodiment includes transmitting, to the user equipment, Radio Resource Control (RRC) configuration information for a Sounding Reference Signal (SRS), the RRC configuration information including information for periodically receiving the SRS from the user equipment; transmitting, to the user equipment, Layer 2 (L2) control information indicating states of the plurality of uplink component carriers; and performing a procedure for periodically receiving the SRS from the user equipment on a corresponding uplink component carrier in use of the RRC configuration information. According to whether the corresponding uplink component carrier is in an available state or a non-available state at a time for receiving the SRS, the SRS or no SRS is received from the user equipment, respectively.

    Abstract: A method for transmitting a downlink signal in a wireless mobile communication system. The method according to one embodiment includes generating a resource indication value (RIV) indicating a start index (S) of consecutive virtual resource blocks (VRBs) and a length (L) of the consecutive VRBs; transmitting downlink control information including resource block allocation information. The downlink control information is common information for plural users, and the resource block allocation information includes the RIV. The method according to the embodiment further includes transmitting the downlink signal on the consecutive VRBs. If Y−1≦└X/2┘, then the RIV is defined by RIV=X(Y−1)+Z, else the RIV is defined by RIV=X(X−Y+1)+(X−1−Z), where X=└NVRB/G┘, Y=L/G, and Z=S/G, in which, L is the length of the consecutive VRBs, S is the start index of the consecutive VRBs, NVRB is the number of VRBs, L is a multiple of G, S is a multiple of G, and G is an integer of 2 or higher.

    Abstract: A reference signal transmission method in a downlink MIMO system is disclosed. The downlink MIMO system supports a first UE supporting N transmission antennas among a total of M transmission antennas (where M>N) and a second UE supporting the M transmission antennas. The method includes transmitting, by a base station (BS), subframe-associated information which designates a first subframe in which data for the first UE and the second UE is transmitted and a second subframe in which data only for the second UE can be transmitted within a radio frame having a plurality of subframes, and transmitting the first subframe and the second subframe. Reference signals corresponding to antenna ports ‘0’ to ‘N−1’ of the N antennas are mapped to the first subframe, and reference signals corresponding to antenna ports ‘0’ to ‘M−1’ of the M antennas are mapped to the second subframe.
