Abstract
A method of accessing a channel in a wireless LAN system is disclosed. A method of accessing a channel in a terminal includes receiving TIM information included in a beacon transmitted by an access point, determining a channel access slot allocated to the terminal based on the TIM information, transmitting a data transmission request to the access point in the channel access slot, and receiving data transmission slot allocation information corresponding to the data transmission request from the access point. Accordingly, a time slot can be prevented from unnecessarily wasting.
