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, 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.
