Abstract
One embodiment of the present invention is a method for performing channel access using a first station (STA) in a wireless communication system, comprising: a step of receiving a traffic indication map (TIM) bitmap; and a step of attempting channel access for a wireless medium in a first time period indicated by the first TIM bitmap. The first STA attempts channel access for the wireless medium in a third time period which is one of the second time periods indicated by the TIM bitmap in the event that the first STA senses an operation of a second STA relating to the wireless medium in the first time period.
