Title:

METHOD AND DEVICE FOR TRANSMITTING/RECEIVING PPDU ON BASIS OF TRIGGER FRAME IN WIRELESS LAN SYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/080649

Kind Code:

A1

Abstract:

Disclosed are an operating method and device in a wireless LAN system. A method carried out by a first STA in a wireless LAN system, according to one embodiment of the present disclosure, comprises the steps of: receiving a trigger frame from a second STA; and, on the basis of the trigger frame, transmitting a trigger-based (TB) physical layer protocol data unit (PPDU) to the second STA, wherein the trigger frame may include i) first information related to at least one uplink (UL) non-orthogonal multiple access (NOMA) transmission characteristic, and ii) second information specifying at least one multiple access (MA) signature value based on the at least one UL NOMA transmission characteristic.
