    Abstract: The present invention relates to a wireless communication system, and more particularly, to a method and an apparatus for accessing a channel in a wireless LAN system. According to one embodiment of the present invention, a method for performing channel access by a station (STA) of a wireless communication system comprises: a step of receiving, from an access point (AP), information about the time window which does not allow channel access of a traffic indication map (TIM) mode STA; and a step of performing channel access based on the time window. In the event that the STA is a non-TIM mode STA, the channel access is performed in the time window. In the event that the STA is a TIM mode STA, the channel access is performed in the time interval indicated by the TIM, excluding the time window.

    Abstract: The present invention relates to a method and apparatus for associating a station (STA) with an access point (AP). The method for associating a first AP with an STA in a wireless LAN includes the steps of: a first AP receiving an association request frame from the STA; the first AP requesting authentication information on the STA from a second AP with which the STA was previously associated; the first AP receiving authentication information on the STA from the second AP, wherein the first and second AP's are linked by a distribution system, the association request frame includes identification information on the second AP, and the authentication information on the STA can include at least one of a paired main key (PMK) and a recertification main session key (rMSK). Accordingly, fast association between the STA and the AP can be achieved by a simplified authentication procedure without repeating a full authentication procedure.

    Abstract: The present invention relates to a method by which a station (STA) which operates in power save mode in a wireless LAN system transmits and receives frames. The method includes the steps of: obtaining a channel access authority on the basis of at least one slot time, wherein each slot time is the unit time when a channel is maintained in an idle state for a channel access by the STA; transmitting a power save (PS) poll frame requesting the transmission of a buffered frame to an access point (AP); and receiving a response frame from the AP in response to the PS poll frame. The length of each slot time is set to be longer than the transmission time of the PS poll frame.
