Title:
IMPROVED TRIGGER FRAME
Document Type and Number:
WIPO Patent Application WO/2022/108327
Kind Code:
A1
Abstract:
The present specification proposes an improved trigger frame structure for triggering a plurality of STAs and a method for allocating bandwidths and RUs to the plurality of STAs on the basis of the improved trigger frame structure. Here, according to an embodiment of the present specification, the plurality of STAs may be STAs supporting different standards. Also, according to another embodiment of the present specification, TB PPDUs transmitted by the plurality of STAs on the basis of the improved trigger frame structure may be A-PPDUs.
