Duplicate detection method for multi-link operation transmissions

A device comprising:

• one or more memories including computer-readable instructions stored therein;
• and
• one or more processors configured to execute the computer-readable instructions to:
• associate the device with two transmission radios to yield a first communication link between the device and a first MLO access point and a second communication link between the device and a second MLO access point, wherein the device is configured to label the first communication link as a primary link and the second communication link as a secondary link, and wherein the device is capable of Multi-Link Operation (MLO) in a wireless network;
• generate a sequence number to be assigned to a frame to be transmitted on the primary link and to a duplicate copy of the frame to be transmitted on the secondary link;
• associate a flag with the duplicate copy of the frame on the secondary link to indicate, to the second MLO access point, that the duplicate copy is a duplicate of the frame sent on the primary link;
• send, from the device to the first MLO access point and the second MLO access point, the frame and the duplicate copy on the primary link and the secondary link, respectively;
• determine that no acknowledgement of the frame on the primary link is received, wherein after expiration of a timer, the second MLO access point designates the frame on the primary link as being lost;
• and
• receive an acknowledgement of the duplicate copy from the second MLO access point after the second MLO access point designates the frame on the primary link as being lost.

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors of a device capable of Multi-Link Operation (MLO) in a wireless network, cause the device to:

• associate the device with two transmission radios to yield a first communication link between the device and a first MLO access point and a second communication link between the device and a second MLO access point, wherein the device is configured to label the first communication link as a primary link and the second communication link as a secondary link, and wherein the device is capable of Multi-Link Operation (MLO) in a wireless network;
• generate a sequence number to be assigned to a frame to be transmitted on the primary link and to a duplicate copy of the frame to be transmitted on the secondary link;
• associate a flag with the duplicate copy of the frame on the secondary link to indicate, to the second MLO access point, that the duplicate copy is a duplicate of the frame sent on the primary link;
• send, from the device to the first MLO access point and the second MLO access point, the frame and the duplicate copy on the primary link and the secondary link, respectively;
• determine that no acknowledgement of the frame on the primary link is received, wherein after expiration of a timer, the second MLO access point designates the frame on the primary link as being lost;
• and
• receive an acknowledgement of the duplicate copy from the second MLO access point after the second MLO access point designates the frame on the primary link as being lost.
