Abstract: The present document relates to a wireless communication system and, more particularly, to a method for performing communication using a downlink (DL) oriented channel in a high-density wireless LAN system and an apparatus therefor. A particular station STA1 configured therefor connects with an AP through a normal channel, switches to a downlink oriented channel during an active mode operation, and receives data from the AP through the DL oriented channel. Meanwhile, data is transmitted to the AP through switching to the normal channel. Here, the first station obtains information on a specific interval for receiving data from the AP through the downlink oriented channel, switches to the normal channel during an interval other than the specific interval, and transmits data to the AP.
