The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for accessing a channel in a WLAN system. The method for accessing a channel from a station (STA) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving from an access point (AP) a first frame including a traffic indication map (TIM) and a restricted access window (RAW) parameter set component; determining a RAW in which channel access of the STA is permitted, on the basis of the RAW parameter set (RPS) component; and transmitting a second frame to the AP from within the RAW that is determined, wherein the RPS component includes at least one RAW indication field, each of the at least one RAW allocation fields further includes information related to transmitting a third frame, which includes information on slot allocation, and wherein the third frame can be received by the STA from the AP at a specific time/location in accordance with the information related to transmitting the third frame. |

1. A method for performing channel access in at least one station (STA) of a wireless communication system, comprising:
receiving, from an access point, a first frame containing a traffic indication map (TIM) element and a restricted access window (RAW) parameter set element; determining a RAW allowing channel access of the STA based on the RAW parameter set (RPS) element; and transmitting a second frame to an access point (AP) within the determined RAW, wherein the RPS element comprises at least one RAW assignment field, wherein each of the at least one RAW assignment field contains information related to transmission of a third frame containing information about assignment of slots, wherein the third frame is received from the AP by the STA at a specific time position according to the information related to transmission of the third frame. |
