    摘要： A method is described of reporting control information in a wireless communication system. A user equipment (UE) supporting at least one cell including a primary cell selects a physical uplink control channel (PUCCH) format among a plurality of PUCCH formats including a first PUCCH format and a second PUCCH format. The first PUCCH format is selected if the UE receives a first physical downlink shared channel (PDSCH) in one of M downlink time division duplex (TDD) subframes on the primary cell. The UE receives a second PDSCH with a downlink assignment index (DAI) in one of the M downlink TDD subframes on the primary cell. The UE does not receive a first physical downlink control channel (PDCCH) corresponding to the first PDSCH on the primary cell. The UE receives a second PDCCH corresponding to the second PDSCH, and transmits a positive-acknowledgement/negative-acknowledgement (ACK/NACK) signal by using the selected PUCCH format.

    摘要： A method for configuring an acknowledgement for a hybrid automatic repeat request (HARQ) in a wireless communication system. The method includes receiving downlink data through one of a first downlink component carrier and a second downlink component carrier from a base station; and determining whether the first or second downlink component carrier is used for receiving the downlink data. If the first downlink component carrier is used for receiving the downlink data, the resource used for the PUCCH is determined by using a control channel element (CCE). If the second downlink component carrier is used for receiving the downlink data, the resource used for the PUCCH is determined by using a radio resource control (RRC) message. The resource used for the PUCCH is associated with an orthogonal sequence with which the ACK/NACK signal is spread.

    摘要： The present invention relates to a method for receiving downlink data and a wireless device using same. The wireless device determines a subframe reception timing difference between a first serving cell and a second serving cell, receives a downlink grant through a downlink control channel of the first serving cell, and receives a downlink transmission block through a downlink shared channel of the second serving cell as instructed by the downlink grant. When the subframe reception timing difference is a predetermined value, at least one orthogonal frequency division multiplexing (OFDM) symbol from among a plurality of OFDM symbols is neglected in a subframe where the downlink shared channel is received.

    摘要： Provided are a method for transmitting an uplink and a wireless device. The wireless device decides a first wireless resource through which a sounding reference signal (SRS) will be transmitted from a first serving cell, and decides a second wireless resource through which an uplink channel will be transmitted from a second service cell. When all or a portion of the first wireless resource and the second wireless resource overlap, and a total transmission power with respect to the SRS and the uplink channel from the overlapping wireless resources exceeds a predetermined maximum transmission power, the wireless device drops the transmission of the SRS and transmits the uplink channel through the second wireless resource from the second service cell.
