US 2026/0247206 A1 · WIRELESS COMMUNICATION METHOD USING MULTILINK, AND WIRELESS COMMUNICATION TERMINAL USING SAME

Abstract

Disclosed are: a traffic transmission method performed by a first multi-link device (MLD) comprising a plurality of stations respectively operating on a plurality of links in a wireless communication system; and an apparatus. In detail, an MLD of the present invention receives a beacon frame from a second MLD including a plurality of access points (APs) operating on the plurality of links, respectively, and transmits and receives a data unit on the basis of the beacon frame. Here, the beacon frame includes a multi-link traffic indication element indicating mapping between at least one traffic identifier (TID) for a buffered unit (BU) of the plurality of APs from among a plurality of TIDs and the plurality of links, according to whether or not mapping between the plurality of TIDs and the plurality of links is default mapping for downlink or bidirectional.

A first multi-link device (MLD) comprising multiple stations, the first MLD device comprising:

a transceiver;
and
a processor configured to:
receive a beacon frame from a second MLD comprising multiple access points (APs);
and
decode the received beacon frame, the beacon frame comprising a multi-link traffic indication element based at least in part on (i) a first traffic identifier (TID) not being mapped to a first enabled link between the first MLD and the second MLD and (ii) on the second MLD having buffered a bufferable unit (BU) with the first TID for the first MLD,
the beacon frame further comprising a traffic indication map (TIM) element associated with the BU for the first MLD.
