    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.

    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: An apparatus and method for a precoding matrix are disclosed. A codebook used for selecting a precoding matrix is comprised of m subgroups each including n precoding matrices. A user equipment indicates a specific precoding matrix selected from the codebook by transmitting to a base station a first codebook index indicating one of the m subgroups and a second codebook index indicating one of n precoding matrices in a subgroup. The base station configures the specific precoding matrix from the codebook based on the first and second codebook indexes.
