METHOD FOR EXCHANGING FRAME FOR LOW POWER DEVICE AND APPARATUS THEREFORE IN WIRELESS LAN SYSTEM THEREFOR

摘要

The present invention relates to a wireless communication system, and more particularly to a method for exchanging a frame for a low power device and an apparatus therefor in a wireless LAN system. A method for enabling an access point (AP) to exchange a frame with a station (STA) in a wireless LAN system according to an embodiment of the present invention includes the steps of receiving the information of the maximum awake time from the STA. When the frame exchange is expected to be accomplished within the maximum awake time, the frame exchange can be performed. When the frame exchange is expected to exceed the maximum awake time, the frame exchange is stopped, and a new back-off procedure can be invoked.
