Abstract
A non-access point (non-AP) multi-link device (MLD) transmits to an access point (AP) MLD a frame for a traffic identifier (TID) on a first link to which the TID is mapped in a TID-to-link mapping. The non-AP MLD receives from the AP MLD a trigger frame on a second link to which the TID is not mapped by the TID-to-link mapping. The non-AP MLD transmits to the AP MLD, in response to the trigger frame, a Quality of Service (QOS) null frame comprising the TID on the second link.
Claims20
A method comprising:
- receiving, by a non-access point (non-AP) multi-link device (MLD) from an access point (AP) MLD, an association frame indicating a traffic identifier (TID)-to-link (TID-to-link) mapping that maps a TID to a first link;
- receiving, 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
- transmitting, 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.
A method comprising:
- transmitting, by an access point (AP) multi-link device (MLD) to a non-access point (non-AP) MLD, an association frame comprising a traffic identifier (TID)-to-link (TID-to-link) mapping that maps a TID to a first link;
- receiving, from the non-AP MLD, a first frame for the TID on the first link;
- transmitting, to the non-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
- receiving, from the non-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.
A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of an access point (AP) multi-link device (MLD), cause the AP MLD to:
- transmit, to a non-access point (non-AP) MLD, an association frame comprising a traffic identifier (TID)-to-link (TID-to-link) mapping that maps a TID to a first link;
- receive, from the non-AP MLD, a first frame for the TID on the first link;
- transmit, to the non-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;
- and
- receive, from the non-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.
