Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING TRIGGER-BASED PHYSICAL LAYER PROTOCOL DATA UNIT IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/121342
Kind Code:
A1
Abstract:
Disclosed are a method and device for a TB PPDU transmission and reception operation in a wireless LAN system. A method by which a first STA transmits a PPDU in a wireless LAN system according to an embodiment disclosed herein may comprise the steps of: receiving a trigger frame from an access point (AP), wherein the trigger frame includes first information related to supporting the transmission of a first type of TB PPDU and a second type of TB PPDU, and second information related to the bandwidth for TB PPDU transmission; and transmitting the first type of TB PPDU to the AP within a first bandwidth in the overall bandwidth identified by a first type of the first STA through the second information, wherein the overall bandwidth includes the first bandwidth for transmitting the first type of TB PPDU and a second bandwidth for transmitting the second type of TB PPDU, and the second type of TB PPDU can be transmitted to the AP within the second bandwidth identified by a second type of the second STA through the second information.
