<p>A method of transmitting control information in a WLAN system using a multi-channel obtained by aggregating a first sub-channel and a second sub-channel is provided. The method includes transmitting, by a transmitting station, a first physical (PHY) preamble over the first sub-channel, transmitting, by the transmitting station, a second PHY preamble over the second sub-channel, and transmitting, by the transmitting station, data symbols using N spatial streams transmitted over the first sub-channel and M spatial streams transmitted over the second sub-channel, wherein the first PHY preamble comprises control information necessary to demodulate and decode the data symbols transmitted over the N spatial streams, and the second PHY preamble comprises control information necessary to demodulate and decode the data symbols transmitted over the M spatial streams, and the first PHY preamble and the second PHY preamble are simultaneously transmitted, and the N and the M are different natural numbers.</p> |
