    摘要： A method of transmitting a data frame by a transmitter in a WLAN system is provided. The method includes generating a data block including at least one data units respectively transmitted through at least one or more spatial streams to at least one receiver, transmitting first control information to the at least one receiver, transmitting second control information to each receiver, and transmitting the data block to the at least one receiver. The first control information includes a length indicator for the data block, a MIMO indicator indicating whether the data block is for SU-MIMO or MU-MIMO, and a spatial stream indication field including information about the number of the spatial streams. The second control information includes a FEC coding field indicating an encoding scheme applied to the data unit and an MCS field indicating an MCS applied to the data unit.

    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.
