1. A non-access point (non-AP) multi-link device (MLD) comprising:
one or more processors; and
a memory storing instructions that, when executed by the one or more processors, cause the non-AP MLD to:
receive, from an access point (AP) MLD, an association frame comprising a traffic identifier (TID)-to-link (TID-to-link) mapping that maps a TID to a first link;
transmit, to the AP MLD, a first frame for the TID on the first link;
receive, from the AP MLD, a first trigger frame on a second link to which the TID is not mapped, wherein the first trigger frame comprises a buffer status report poll (BSRP) trigger frame or a basic trigger frame; and
transmit, to the AP MLD, in response to the first trigger frame, a Quality of Service (QoS) null frame comprising the TID on the second link, wherein the QoS null frame comprises a first buffer status report (BSR) for the TID.
