Title:
TRIGGER FRAME-BASED PPDU TRANSMISSION/RECEPTION METHOD AND DEVICE IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/219386
Kind Code:
A1
Abstract:
A trigger frame-based PPDU transmission/reception method and device in a wireless LAN system are disclosed. The method performed by means of a station (STA) in a wireless LAN system, according to one embodiment of the present disclosure, may comprise the steps of: receiving, from an access point (AP), a trigger frame including a common information field (common info field); and transmitting, to the AP, a trigger based physical layer protocol data unit (TB PPDU) corresponding to one of one or more TB PPDUs triggered by means of the trigger frame. The common information field comprises an aggregated PPDU (A-PPDU) related subfield, and a configuration of the one or more TB PPDUs can be indicated on the basis of the A-PPDU related subfield and at least one other subfield included in the common information field.
