    Abstract: A channel access method in WLAN system is provided. The method includes receiving packets transmitted from a higher protocol layer, classifying the packets to map the packets to ACs to which the packets correspond, transmitting the packets to queues corresponding to the ACs to which the packets are mapped, among a plurality of queues by ACs, independently applying a channel access function to each of the plurality of queues by ACs by avoiding a collision among the plurality of queues by ACs, transmitting a packet determined to be transmitted first, according to the application result of the channel access function. The packet includes a first frame to be transmitted to a first terminal and a second frame to be transmitted to a second terminal. The plurality of queues by ACs are queues with respect to the first frame to be transmitted to the first terminal.

    Abstract: A method and an apparatus for allocating a flexible transmission slot in a wireless local area network (LAN) system are disclosed. A flexible transmission slot allocation method of an access point (AP) in a wireless local area network (WLAN) system according to an exemplary embodiment includes transmitting a beacon including a traffic indication map (TIM) bit to a station, receiving a power save poll (PS-Poll) from the station in a slot implicitly allocated by the TIM bit, and transmitting an acknowledgement (ACK) including transmission slot allocation information on downlink data to the station.
