A method of performing a link adaptation procedure for multi-user transmission in a wireless local area network (WLAN) system is provided. The method includes receiving a modulation and coding scheme (MCS) feedback request transmitted by an access point (AP) to a plurality of stations, estimating an MCS by considering a spatial stream corresponding to the MCS feedback request transmitted to the other stations, and transmitting an MCS feedback response comprising the estimated MCS to the AP. The link adaptation procedure can be performed by considering a wireless communication environment on a real time basis.
