    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.

    Abstract: A method of controlling an uplink transmission in a wireless communications system, and a user equipment therefore are discussed. The method according to one embodiment includes configuring the user equipment with multiple component carriers; receiving first configuration information for allocating one or more component carrier sets; receiving second configuration information for periodically transmitting an uplink signal; receiving control information for configuring states of component carriers, by which a downlink component carrier and an uplink component carrier are controlled to be in a same state; and performing a procedure for periodically transmitting the uplink signal on an uplink component carrier in use of the first configuration information, the second configuration information and the control information. When the uplink component carrier is in the active state, a transmission of the uplink signal is performed. When the uplink component carrier is in the non-active state, the transmission of the uplink signal is skipped.
