    • The present invention relates to a wireless communication system, and more particularly, discloses a method and a device for efficient feedback in a wireless communication system supporting multiple antennas. According to one embodiment of the present invention, the method for transmitting channel status information on a downlink transmission through an uplink, in the wireless communication system, comprises the following steps: transmitting a rank indicator (RI) and a precoding type indicator (PTI) based on a first reporting period, when the PTI has a first value; transmitting during the first reporting period a broadband first precoding matrix indicator (PMI) based on a second reporting period; transmitting at least once during the second reporting period a broadband second PMI and a broadband channel quality indicator (CQI); transmitting the rank indicator (RI) and the PTI based on the first reporting period, when the PTI has a second value; transmitting during the first reporting period the broadband second PMI and the broadband CQI based on a third reporting period; and transmitting at least once during the third period a subband second PMI and a subband CQI, wherein the subband CQI on an entire cycle of a set bandwidth portion (BP) can be transmitted at least once.

    • The present invention relates to a wireless communication system, and to a method and apparatus for efficiently transmitting control information to support an uplink multiple antenna transmission technique. According to one embodiment of the present invention, 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.
    • 无线通信系统技术领域本发明涉及无线通信系统以及用于有效发送控制信息以支持上行链路多天线传输技术的方法和装置。 根据本发明的一个实施例,一种用于发送关于上行链路多天线传输的控制信息的方法可以包括以下步骤:通过PDCCH发送用于调度多个数据块的上行链路传输的DCI; 接收由DCI调度的多个数据块; 通过PHICH向多个接收数据块中的每一个发送指示肯定确认或否定确认的信息; 并且接收用于否定的确认数据块的重传。 当否定确认数据块的数量不等于PDCCH中指示的数字数据块时,预编码矩阵用于与对应于否定确认数据块的层数相当的传输层数 ,可以用于重传。
