Abstract: A method for transmitting acknowledgement/negative acknowledgement (ACK/NACK) signals by an apparatus in a wireless communication system. The apparatus spreads ACK/NACKs using spreading codes of a spreading factor, the spreading factor being one of a first spreading factor equal to 2 and a second spreading factor equal to 4. The apparatus transmits one or more physical hybrid automatic repeat request (HARQ) indicator channel (PHICH) groups allocated in units of four resource elements, each PHICH group carrying up to four ACK/NACK signals for the first spreading factor, and up to eight ACK/NACK signals for the second spreading factor. A total number of allocated PHICH groups for the first spreading factor is determined as twice a total number of allocated PHICH groups for the second spreading factor. Each ACK/NACK signal is identified using an index pair of a PHICH group index and a spreading code index.

Abstract: A method and a user equipment for controlling an uplink transmission at in a wireless communications system are discussed, the user equipment being configured with multiple component carriers. The method according to an embodiment includes receiving, from a base station, Radio Resource Control (RRC) configuration information for a channel status information report; and performing a procedure for periodically transmitting channel status information to the base station. If the corresponding downlink component carrier is in an active state at a time for transmitting the channel status information, a transmission of the channel status information report is performed at the time. If the corresponding downlink component carrier is in a non-active state at a time for transmitting the channel status information report, the transmission of the channel status information report is skipped at the time. Signal reception is limited by the user equipment on a downlink component carrier in the non-active state.

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.
