    摘要: A method for transmitting uplink control information of a user equipment in a multi-carrier system is provided. The method includes: transmitting each of acknowledgement/not-acknowledgement (ACK/NACK) for downlink data transmitted by a base station through multiple downlink component carriers; and transmitting channel state information indicating a state of a downlink channel to the base station, wherein each of the ACK/NACK and the channel state information are allocated to the same uplink control channel resource in a subframe, and if each of the ACK/NACK and the channel state information are reserved to be transmitted on the same subframe, each of the ACK/NACK only is transmitted. Accordingly, a user equipment can transmit uplink control information while preserving a single-carrier property of an uplink signal in a multi-carrier system using carrier aggregation.

    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.
