According to the present invention, a station that does not receive a TIM or DTIM is to be switched so as to operate between a wakeup mode and a sleep mode for power saving. In order to set an efficient wakeup time, the STA may listen to beacon frame information from an AP and access a channel through information included in the beacon frame information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel access method and apparatus in wireless LAN system","description":"The present invention relates to a method for converting, by a station (STA), a non-traffic indication map (TIM) mode into a TIM mode and performing channel-accessing.
