The present invention relates to a method of processing a data frame in a wireless communication system using multi-user multiple input multiple output. The method comprises: receiving, by a receiver, group control information to assign one or more groups from an access point, the group control information indicating a group sequence number (502), bitmap information (503) and stream information (504); and receiving, by the receiver, a data frame from the access point after receiving the group control information, the data frame including the group sequence number and the stream information, wherein the bitmap information (503) is used to inform whether the data frame is received from a corresponding group when the receive belongs to a plurality of groups that are expressed using the group sequence number, and wherein the stream information (504) indicates a stream location to be received by the receiver in a MU-MIMO environment and indicates a position for at least one stream of a plurality of streams that are classified into a plurality of groups. |
