Abstract
A wireless communication network includes an access point (AP) multi-link device (MLD) and a non-AP MLD. The AP MLD transmits to a first station affiliated with the non-AP MLD via a first link an indication of pending traffic on a second link. A second station affiliated with the non-AP MLD transmits via the second link a trigger frame to retrieve pending traffic. The AP MLD transmits the pending traffic to the second station affiliated with the non-AP MLD via the second link in response to receiving the trigger frame. In addition, various embodiments that are understood through the present disclosure may be implemented.
Claims17
An access point (AP) multi-link device (MLD), comprising:
- one or more processors comprising processing circuitry;
- and
- memory storing instructions that, when executed by the one or more processors individually and/or in any combination, cause the AP MLD to:
- transmit, to a non-AP MLD via a first link, an indication indicating presence of pending traffic on a second link and at least one recommended link on which the non-AP MLD retrieves the pending traffic on the second link;
- receive, from the non-AP MLD via the at least one recommended link, a trigger frame to retrieve buffered traffic from the AP MLD;
- and
- transmit, to non-AP MLD via the at least one recommended link, buffered traffic in response to receiving the trigger frame, and
- wherein the AP MLD determines the at least one recommended link based on amount of traffic or incoming traffic rate in the AP MLD.
A non-access point (AP) multi-link device (MLD), comprising:
- one or more processors comprising processing circuitry;
- and
- memory storing instructions that, when executed by the one or more processors individually and/or in any combination, cause the non-AP MLD to:
- receive, from an AP MLD via a first link, an indication indicating presence of pending traffic on a second link and at least one recommended link on which the non-AP MLD retrieves pending traffic on the second link;
- transmit, to the AP MLD via the at least one recommended link, a trigger frame to retrieve buffered traffic from the AP MLD;
- and
- receive, from the AP MLD via the at least one recommended link, buffered traffic from the AP MLD,
- wherein the at least one recommended link is determined based on amount of traffic or incoming traffic rate in the AP MLD.
A non-access point (AP) multi-link device (MLD), comprising:
- one or more memories;
- and
- one or more processors comprising processing circuitry operatively coupled to the one or more memories, the one or more processors configured, individually and/or in any combination, to cause:
- receiving, from a first AP affiliated with an AP MLD via a first link, an indication of traffic status of the AP MLD indicating at least recommended link on which the non-AP MLD retrieves buffered traffic;
- determining a second link among the at least recommended link as a link for retrieving buffered traffic from the AP MLD;
- transmitting, to a second AP affiliated with the AP MLD via the second link, a trigger frame to retrieve buffered traffic from the AP MLD;
- and
- receiving, from the second AP affiliated with the AP MLD via the second link, buffered traffic from the AP MLD, and
- wherein the at least one recommended link is determined based on amount of traffic or incoming traffic rate in the AP MLD.
