    摘要: A method and an apparatus for receiving downlink data in a multi-carrier system are provided. A terminal receives a downlink grant on a physical downlink control channel (PDCCH) via a first component carrier, and determines a transmission power of a physical downlink shared channel (PDSCH) depending on whether a control channel exists in each orthogonal frequency division multiplexing (OFDM) symbol of a subframe of a second component carrier that is indicated by the downlink grant. Based on the transmission power of the PDSCH, the terminal receives downlink data on the PDSCH indicated by the downlink grant via the second component carrier. When a control channel and a data channel coexist in the same OFDM symbol, the reliability of receiving the control channel can be increased.

    摘要: In the event ACK/NACK information on downlink data transmitted on one or more carriers must be transmitted on a PUCCH together with SR, user equipment of the present invention always modulates the ACK/NACK information to a first complex modulation symbol regardless of the number of the carriers when a specific carrier is ACK and the other carriers are NACKs, or the specific carrier is ACK and ACK/NACK bundled for other carriers is NACK. Also, the user equipment always modulates the ACK/NACK information to a second complex modulation symbol regardless of the number of the carriers when a specific carrier is NACK and the other carriers are NACKs, or the specific carrier is ACK and the ACK/NACK bundled for the other carriers is NAC. According to the present invention, regardless of the number of carriers needed for the user equipment, at least ACK/NACK information on the specific carrier can be exactly transmitted to a base station.
