Abstract
A multi-link device may be configured to initiate transmission of a first data unit on a first wireless link of a first multi-link device, and request transmission of a trigger from a second multi-link device on a second wireless link. In response to receiving the trigger, the multi-link device may align a last symbol end time of a response transmission on the second wireless link with a last symbol end time of the first data unit being transmitted on the first multi-link device.
Claims20
A system comprising:
- a device configured to transmit and receive communications on a plurality of links, the device configured to:
- initiate transmission of a first data unit on a first link of the plurality of links;
- transmit a frame to a second device, the frame comprising a request for the second device to transmit a trigger;
- and
- responsive to receiving the trigger on at least one of the first link or at least another link of the plurality of links, align an end of a last symbol of the transmission on the first data unit on the first link with an end of a last symbol of a second transmission of a second data unit on the at least another link.
2 more elements
A system comprising:
- a device configured to transmit and receive communications over a plurality of links, the device configured to:
- receive a request-to-send (RTS) frame from a second device, the RTS frame setting a value of a received address (RA) to a multi-link device (MLA) address of the device;
- determine, based at least on the value of the RA, to respond to the RTS frame with a trigger instead of a clear-to-send message;
- and
- transmit the trigger.
2 more elements
A system comprising:
- a device configured to transmit and receive communications over a plurality of links, the device configured to:
- transmit a request-to-send (RTS) frame to a second device;
- receive a channel time allocation (CTA) message in response to the RTS frame, the CTA message including a duration field and information on one or more parameters of a following frame;
- allow the CTA message in response to the RTS frame;
- and
- transmit a physical layer protocol data unit (PPDU).
