FIELD: radio engineering, communication.SUBSTANCE: invention particularly discloses a method of performing a link adaptation procedure which includes steps of: 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.EFFECT: performing a link adaptation procedure for multi-user transmission taking into account a wireless communication environment on a real time basis.6 cl, 8 dwg |
