    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.

    摘要: The present invention relates to a wireless communication system. The present invention relates to a method for transmitting ACK/NACK in a wireless communication system in which carrier aggregation is set, and an apparatus therefor. Specifically, the present invention relates to an ACK/NACK transmission method and an apparatus therefor, the method comprising the steps of: receiving information on a plurality of physical uplink control channel (PUCCH) resources via upper layer signaling; receiving a transmit power control (TPC) field on a secondary carrier through a physical downlink control channel (PDCCH); receiving data indicated by the PDCCH; and transmitting ACK/NACK for the data, wherein the ACK/NACK is transmitted using a PUCCH resource which is indicated by the value of the TPC field among the plurality of PUCCH resources.
