METHOD AND SYSTEM FOR IMPROVING WIRELESS LINK EFFICIENCY

摘要

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.

1. A method for wireless link transmission, comprising:
receiving 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, wherein each of the packets of a respective multi-TID aggregate frame have the same virtual traffic category indicator (virtual TID) in a corresponding packet header, and wherein two or more packets in the multi-TID aggregate frame have different original traffic category indicators (TIDs) in a corresponding packet payload; computing a TID packet error rate for a respective TID based at least on the block acknowledgement; in response to determining that the TID packet error rate for the respective TID is greater than a predetermined threshold, reserving a number of packet slots in a second aggregate frame for duplicate packets of the respective TID; generating the second multi-TID aggregate frame that includes duplicate packets for the respective TID in the number of reserved packet slots; and sending the second multi-TID aggregate frame to the destination device via the wireless link.
