IDLE CHANNEL INFORMATION-BASED SCHEDULING METHOD IN WIRELESS LAN SYSTEM AND DEVICE FOR SAME

摘要

The present invention relates to a scheduling method on the basis of idle channel information about whether each channel is in an idle channel state or a busy state in a wireless LAN system and a device for same. To this end, a station performs a search for a plurality of wireless LAN channels, thus obtains idle channel information, which is information about whether each channel is in an idle state or a busy state, and transmits an uplink frame comprising the idle channel information to an AP. Therefore, a downlink frame comprising scheduling information on the basis of the idle channel information can be received from the AP.
