FIELD: communication.
SUBSTANCE: invention relates to a wireless communication and can be used for transmission delay in slot access channel in wireless LAN system. Method of channel accessing by station (STA) in wireless LAN system according to disclosed invention embodiment may include: receiving restricted access window (RAW) configuration information for STA from access point (AP); performing transmission delay procedure using transmission delay function second state for access to channel in RAW range and performing transmission delay procedure using transmission delay function first state, when RAW ends. STA supports multiple transmission delay function states, which include transmission delay function first state, used outside RAW, and transmission delay function second state used within RAW.
EFFECT: technical result is increased efficiency of network resources using and fairness.
