    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.

    摘要： A method for transmitting downlink reference signal in a multi-antenna wireless communication system is disclosed. The method includes allocating RSs for a first antenna group to a subframe having a predetermined area with different access levels for user equipments having different access capabilities, pairing RSs for a second antenna group with RSs for the first antenna group, allocating the paired RSs to the predetermined area of the subframe in code division multiplexing, and transmitting the subframe on the downlink.
