<p>PURPOSE: A control signal transmission method of a wireless LAN system and an apparatus for supporting the same are provided to transmit a multiple data frame to a station and to secure the existence of a VHT station and a legacy station. CONSTITUTION: A frame generating unit generates a first control signal frame and a second control signal frame. A frame transmitting unit transmits the frame through multiple antennas. A VHT-SIG1(Very High Throughput-signal 1) field(230) includes common information about the SDMA transmission of the transmitted field. A VHT-SIG2 field(240) includes a parameter value which is used for transmitting SDMA(Spatial Division Multiple Access).</p> |
