A channel access method in a wireless local area network (WLAN) system using a multi-channel configured by aggregation of a plurality of subchannels is provided. The method includes receiving from an access point (AP) a multi-channel switching request frame for requesting a first station operating in a first subchannel constituting the multi-channel to switch to a second subchannel constituting the multi-channel and transmitting a multi-channel switching response frame for reporting whether to switch to the second subchannel in response to the multi-channel switching request frame. |
