    摘要： Disclosed are a method and a device for performing HARQ in a multiple antenna system. A terminal transmits uplink data via a plurality of antennas and through a Physical Uplink Shared Channel (PUSCH), and receives an ACK/NACK (Acknowledgement/Non-Acknowledgement) signal indicating whether or not the uplink data has been received, the signal being received via the plurality of antennas and through a PHICH (Physical Hybrid-ARQ Indicator Channel) which corresponds to the PUSCH. A downlink resource to which the PHICH is mapped is determined on the basis of the index (IPRB—RAlowestindex) of the smallest Physical Resource Block (PRB) among the PRBs to which the PUSCH is mapped, uplink DMRS (Demodulation Reference Signal) cyclic shift parameters (nDMRS) and Orthogonal Code Cover (OCC) index.

    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： The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for transmitting reference signals in uplink MIMO transmission. According to one embodiment of the present invention, the method for transmitting uplink signals through a terminal in the wireless communication system comprises the steps of: receiving control information including the information on a cyclic shift and/or an orthogonal cover code; allocating the multiplexed reference signals onto an uplink subframe; and transmitting the subframe through a multi-antenna. When the uplink MIMO transmission is multiuser MIMO transmission, the reference signals of the terminal and the reference signals of other terminals can be multiplexed by using the orthogonal cover code.
