Abstract: One embodiment of the present invention provides a wireless system. During operation, the system can determine a set of contiguous virtual sequence numbers and a virtual traffic category indicator for a set of packets belonging to different traffic categories associated with a network protocol stack. Each packet includes an original sequence number and an original traffic category indicator. The system then generates an aggregate frame comprising modified packets of the set of the packets. The system modifies a respective packet by modifying a payload of the packet to include the original sequence number and the original traffic category indicator of the packet and modifying a header of the packet to include a virtual sequence number of the set of contiguous virtual sequence numbers and the virtual traffic category indicator. The system determines that a wireless medium for a wireless transceiver is available for transmitting the aggregate frame.

Abstract: A transmission system can improve transmission efficiency of a wireless link using multi-TID aggregate frames. The system can receive a block acknowledgement from a destination device, in response to sending a first multi-TID aggregate frame to the destination device via a wireless link. The system can compute a packet error rate for a respective TID based at least on the block acknowledgement. If the system determines that the packet error rate for the respective TID is greater than a predetermined threshold, the system can reserve a number of packet slots in a second aggregate frame for duplicate packets of the respective TID. The system may then generate the second multi-TID aggregate frame that includes duplicate packets for the respective TID in the number of reserved packet slots, and can send the second multi-TID aggregate frame to the destination device via the wireless link.

Abstract: One embodiment of the present invention provides a system for improving transmission efficiency of a wireless link. During operation, the system receives a packet for transmission, where in the packet includes an original sequence number. The system then modifies the packet by including a virtual sequence number in a header of the packet and including the original sequence number in a payload of the modified packet. The system further aggregates a number of modified packets into an aggregate frame and transmits the aggregate frame to a destination device. The virtual sequence number facilitates stateless transmission of the encapsulated packets and allows the aggregate frame to have a maximum allowable number of packets while accommodating both re-transmitted packets and regular packets.
