    摘要: The present invention relates to a method for transmitting control information regarding uplink multiple antenna transmission may comprise the steps of: transmitting DCI for scheduling the uplink transmission of a plurality of data blocks through a PDCCH; receiving the plurality of data blocks scheduled by the DCI; transmitting information which indicates positive acknowledgement or negative acknowledgement to each of the plurality of received data blocks through the PHICH; and receiving retransmission for the negative acknowledged data blocks. When the number of the negative-acknowledged data blocks is not equal to the number data blocks indicated in the PDCCH, a pre-coding matrix, which is for the number of transmission layers equivalent to that of layers corresponding to the negative-acknowledged data blocks, may be used for retransmission.

    摘要: According to an aspect of the present invention, an apparatus for data transmission is provided. The apparatus includes a data processing unit generating a data symbol by performing channel coding and constellation mapping on an information bit, a single carrier-frequency division multiple access (SC-FDMA) modulator generating an SC-FDMA symbol by performing discrete Fourier transform (DFT) on the data symbol, by mapping the DFT performed-data symbol to subcarriers, and by performing inverse fast Fourier transform (IFFT) on the subcarrier mapped-DFT performed-data symbol, and a plurality of transmit antennas transmitting the SC-FDMA symbol. A single carrier-frequency division multiple access (SC-FDMA) system can effectively use frequency switched transmit diversity (FSTD) to reduce a peak-to-average power ratio (PAPR) and to maintain a single-carrier property.
