Abstract: The present document relates to a power reduction mode operation of a STA in a wireless communication system. To this end, during the STA's power saving mode operation, the TIM (traffic indication map) reception, the PS poll signal transmission, and the data reception are performed through one of a downlink oriented channel and a general channel distinguished from the downlink oriented channel, and the STA may previously acquire information on whether the TIM reception, the PS poll signal transmission, and the data reception are performed through one channel of the downlink oriented channel and the general channel.

Abstract: A method and an apparatus for receiving a downlink frame in a wireless LAN are disclosed. The method and apparatus for receiving a downlink frame in a wireless LAN may comprises the steps of: an STA receiving from an AP a downlink frame via a downlink dedicated channel; and the STA transmitting to the AP a response frame related to the downlink frame via the downlink dedicated channel. The downlink dedicated channel allows transmission only of a contention-free downlink frame by the AP and a response frame by the STA, and restricts transmission of an independent uplink frame by the STA, wherein the independent uplink frame may be an uplink frame other than a response frame among uplink frames that are transmitted from the STA to the AP.
