METHOD FOR TRANSMITTING FRAME IN WIRELESS LAN SYSTEM AND WIRELESS TERMINAL USING SAME

WIPO Patent Application WO/2018/016864

A1

A method for transmitting a frame in a wireless LAN system, according to one embodiment of the present specification, comprises the steps of: a wireless terminal determining whether a channel is usable based on directional CCA which confirms the state of individual channels; determining, as a primary AC, the first AC type from a plurality of AC types to complete a first back-off process, when either a first channel or a second channel is determined as usable; and determining a primary AC from the plurality of AC types once again by performing a second back-off process, when transmission of traffic data included in a transmission que corresponding to the primary AC using at least one directional antenna module associated with at least one channel is determined to be impossible.
