The method comprises: generating a data block including one or more data units, each of which is to be transmitted to one or more receivers through one or more spatial streams; transmitting first control information to said one or more receivers; transmitting second control information to each receiver, wherein the second control information includes a forward error correction (FEC) coding field for indicating the encoding technique applied to the data units and a modulation and coding scheme (MCS) field for indicating the MCS applied to the data units; and transmitting the data block to said one or more receivers. The first control information includes a length indicator, a multiple-input and multiple-output (MIMO) indicator, and a spatial stream indicating field, wherein the indicators and the field are intended for said data block. The MIMO indicator indicates whether the data block is for single user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). The spatial stream indicating field includes information on the number of said spatial streams.
