    摘要: Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses a CoMP set ID or does not apply a frequency shift value, or uses a serving cell ID or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset resource region. A method for transmitting the CoMP-zone-specific reference signal is configured such that the pattern of the sequence of CoMP reference signals varies in each of the CoMP zones, and the pattern can be set in advance. The reference signal is multiplexed using an orthogonal code and transmitted to plural terminals using the same CoMP zone.

    摘要: Disclosed is a method for setting a carrier indication field indicating an element carrier in a multi-carrier system using a plurality of element carriers. The method includes: transmitting a value of a carrier indication field (CIF) and first CIF setting information that indicates a first mapping relationship between element carriers; transmitting downlink control information (DCI) including a carrier indication field; and transmitting a value of a CIF and second CIF setting information that indicates a second mapping relationship between element carriers, wherein the carrier indication field is a field indicating any one of the plurality of element carriers, and at least one element carrier is mapped with the same carrier indication field value in the first and second mapping relationships.

    摘要: Provided are a method and apparatus for transmitting a reference signal in a multi-antenna system. A terminal generates a plurality of reference signal sequences in which cyclic shift values different from each other are allocated to the respective plurality of layers, and generates a single carrier-frequency division multiple access (SC-FDMA) symbol to which the plurality of reference signal sequences are mapped. The SC-FDMA symbol is transmitted to a base station via a plurality of antennas. The cyclic shift values allocated to the respective layers are determined on the basis of a first cyclic shift value, which is a cyclic shift value allocated to a first layer from among the plurality of layers, and cyclic shift offsets which are allocated to the respective layers and which are different from each other.

    摘要: Provided are an apparatus and method of performing an uplink hybrid automatic repeat request (HARQ) in a wireless communication system. A terminal transmits a transport block to a base station via a physical uplink shared channel (PUSCH) using uplink resource allocation and receives an ACK/NACK signal for the transport block from the base station via a physical hybrid-ARQ indicator channel (PHICH). A PHICH resource used for transmitting the PHICH is identified from a PUSCH resource used for transmitting the PUSCH, and the PUSCH resource is mapped to the PHICH resource according to an uplink element carrier through which the transport block is transmitted.
