Title:
MULTIUSER FRAME TRANSMISSION METHOD IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/021858
Kind Code:
A1
Abstract:
An embodiment of the present invention relates to a method for performing a clear channel assessment (CCA) by STA in a wireless communication system, the method comprising the steps of: receiving a frame including a coloring bit; changing a CCA level to a first level when the coloring bit indicates a basic service set (BSS) to which the STA belongs, and changing a CCA level to a second level when the coloring bit indicates a BSS to which the STA does not belong; and performing the CCA according to the first level or the second level, wherein when the frame has an OFDM-based format, the frame includes a coloring disable bit, and when the coloring disable bit indicates that the frame is a multiuser transmission-related trigger frame, the STA does not perform a change of the CCA level without regard to information indicated by the coloring bit.
