    摘要: An apparatus and method of transmitting ACK/NACK (acknowledgement/negative ACK) information in downlink and an apparatus and method of receiving the ACK/NACK information are disclosed. The present invention configures ACK/NACK information on multiple UL codeword transmission using a PHICH and at least one NDI, whereby the ACK/NACK information on the multiple UL codeword transmission is transmitted to a user equipment without additional PHICH resource allocation. The present invention extends the conventional HI codeword and/or arranged position on a signal constellation, thereby transmitting ACK/NACK information on multiple UL codeword transmission to a user equipment without additional PHICH resource allocation.

    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.

A terminal transmits a plurality of first transmission symbols via a plurality of antennas using a first spatial processing performed on the first transmission symbols, and transmits a plurality of second transmission symbols via a plurality of antennas using a second spatial processing performed on the second transmission symbols. At least one column or at least one row of a first spatial processing matrix used in the first spatial processing is switched to form a second SFBC matrix used in the second spatial processing. According to the present invention, peak-to average power (PAPR)/cubic metric (CM) ratio can be kept at a low level, and imbalanced transmission power among antennas can be evened out.
