    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.

The method includes receiving a data block for requesting a modulation and coding scheme (MCS) feedback from a requesting station, the data block including a data field and a stream indicator indicating a number of at least one spatial stream in the data field; determining, the MCS feedback based on the data block; and, transmitting the MCS feedback to the requesting station, the MCS feedback including a recommended MCS and a recommended stream indicator indicating a number of at least one recommended spatial stream. The number of the at least one recommended spatial stream in the MCS feedback is equal or less than the number of the at least one spatial stream in the data block.

    摘要： A method of transmitting modulation and coding scheme (MCS) feedback (MFB) in a wireless local area network system is provided. The method is performed by a first station and includes receiving, from a second station, a physical layer convergence procedure(PLCP) protocol data unit(PPDU), estimating a MFB based on the PPDU and transmitting, to the second station, C feedback information including a MFB field and a MFB type field. The MFB field includes the MFB and the MFB type field indicates whether or not the MFB is in response to a MFB request(MRQ) of the second station.

    摘要： A method for a channel sounding in a wireless local area network is provided. The method includes transmitting a null data packet announcement (NDPA) frame, to a plurality of receivers, the NDPA frame requesting a channel statement information feedback and announcing that a null data packet (NDP) frame is to be transmitted; transmitting the NDP frame being a basis of channel estimation for the plurality of receivers; receiving a first feedback frame from a first receiver among the plurality of receivers, transmitting a feedback poll frame to a second receiver; and, receiving a second feedback frame from the second receiver, the second feedback frame including second channel state information estimated by the second receiver. If the first receiver fails to perform the channel estimation, the first feedback frame is a null feedback frame. The null feedback frame is a feedback frame not including channel state information.
