    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: The present invention provides a method and an apparatus for receiving reception acknowledgement for HARQ (Hybrid Automatic Repeat Request) in a wireless communication system. A terminal receives, from a base station, an uplink resource allocation that includes information on a plurality of allocated RBs (Resource Blocks) within a subframe that includes the plurality of RBs, and transmits uplink transmission blocks to a PUSCH (Physical Uplink Shared Channel) by using the plurality of allocated RBs on the subframe. The terminal receives, from the base station, ACk/NACK signals on a PHICH (Physical Hybrid-ARQ Indicator Channel). PHICH resources used on the PHICH are identified by the lowest index among indexes of the plurality of allocated RBs, and at least two of the indexes of the plurality of RBs are linked by being overlapped with the same PHICH resource.

    摘要: The present invention discloses a method in which a base station transmits a downlink signal in a wireless communication system. In detail, the method comprises the following steps: allocating a transmitting resource to data symbols for transmitting downlink signals, in the direction of increasing a frequency index; and transmitting the downlink signal to a terminal, using the allocated resource. The frequency band of preset orthogonal frequency division multiplexing (OFDM) symbols, from among the transmitting resource, contains a control domain and a segment band. The step of allocating the transmitting resource comprises the step of puncturing the data symbol using a control channel, to which the control domain contained in the preset OFDM symbols is allocated.
