摘要:
A method of transmitting a multiple input multiple output (MIMO) packet by a transmitter in a wireless local area network (WLAN) system is provided. The method includes: generating a MIMO packet including at least one spatial stream set transmitted respectively to at least one receiver, wherein each spatial stream set is encoded on the basis of one of two encoding schemes; transmitting first control information including a MIMO indicator and a first modulation and coding scheme (MCS) field, wherein the MIMO indicator indicates whether the MIMO packet is for single user (SU)-MIMO or multi user (MU)-MIMO, and the first MCS field indicates an MCS used for the MIMO packet if the MIMO packet is for SU-MIMO transmission, and indicates an encoding scheme applied for each of the spatial stream sets if the MIMO packet is for MU-MIMO transmission; and transmitting the MIMO packet to at least one receiver.
