A method of transmitting multiple frames in a wireless local area network (WLAN) system supporting multi user-multiple input multiple output (MU-MIMO) is provided. The method comprises transmitting a first frame and a second frame consecutively to a first station (STA) and transmitting a third frame and a fourth frame consecutively to a second STA, wherein a transmission start time of the first frame and a transmission start time of the third frame are aligned to each other, and wherein a transmission start time of the second frame and a transmission start time of the fourth frame are aligned to each other. |
