    摘要： The present invention relates to a wireless access system, and more particularly, to a method for controlling uplink transmission power in consideration of a transmission rank in a multi-antenna environment. A method for controlling the transmission power of an uplink data channel at a transmitting end which supports a plurality of transmission ranks according to one embodiment of the present invention, comprises the steps of: determining a first transmission power using at least one rank variable dependent on the transmission rank in a specific subframe; comparing the determined first transmission power with a second transmission power which is the preset maximum transmission power; and determining the value judged to be smaller than the result of the comparison to be the transmission power of the data channel.

    摘要： A method for transmitting data by applying a precoding matrix in an open-loop multiple input multiple output (MIMO) system is disclosed. The method comprises selecting a precoding matrix and applying the selected precoding matrix to data during initial transmission; selecting a precoding matrix and applying the selected precoding matrix to data to be retransmitted; and retransmitting the data to which the precoding matrix is applied, wherein an index of the precoding matrix applied to the data is determined based on the times of current retransmission times of the data and index of the precoding matrix applied during initial transmission of the data.

    摘要： Disclosed is a method whereby a channel quality indicator is fed back by a terminal in a multiple-antenna wireless communication system. More specifically, the method comprises the steps of: receiving reference signals corresponding to a plurality of data streams from a base station; using the reference signals to calculate a channel quality indicator; and transmitting the calculated channel quality indicator to the base station; and, in the step in which the channel quality indicator is calculated, the channel quality indicator is calculated under the assumption that at least one of the reference signals has been transmitted using wither the spatial-multiplexing technique or the transmit diversity technique, depending on the feedback setting of the terminal.
