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 that are different from each other are allocated to the respective plurality of layers, and generates an orthogonal frequency division multiplexing (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. Each of the reference signal sequences is multiplied by either +1 or -1 in accordance with an orthogonal covering code (OCC) index corresponding to the cyclic shift field in a DCI format transmitted via a physical downlink control channel (PDCCH) for each layer.

摘要： A method of transmitting feedback information in a multiple antenna system is provided. The method includes selecting at least one subband selected from a plurality of subbands according to subband preset information, the subband preset information being a preset on data processing settled for each of the plurality of subbands, and transmitting a subband index of the selected subband. Only a subband index is fed back instead of separately transmitting a precoder index or a modulation and coding scheme (MCS) level index to each UE, thereby reducing feedback overhead.

摘要： The present invention provides a method and apparatus for performing hybrid automatic repeat request (HARQ) in a wireless communication system. A terminal transmits a plurality of code words on a physical uplink shared channel (PUSCH) and receives a plurality of acknowledgement/non-acknowledgement (ACK/NACK) signals, which indicates if each of the plurality of code words has been received, on each physical hybrid-ARQ indicator channel (PHICH) corresponding to the respective code words. A downlink resource for which each of the PHICHs is mapped is determined based on the smallest physical resource block (PRB) index (I ) among PRBs mapped by the PUSCH and on an uplink demodulation reference signal (DMRS) circular shift parameter (n), and those downlink resources for which PHICHs are mapped respectively do not overlap each other.
