The document proposes a dual queue scheme at access points to improve fairness between uplink and downlink TCP flows in wireless local area networks. The scheme employs two queues - one for downlink TCP data packets and another for uplink TCP ACK packets. By selecting the queues with different probabilities, the access point can control the ratio of TCP data and ACK sending rates to achieve fairness. Simulation results show that the dual queue scheme is effective at resolving the unfairness problem in a simple way without modifying existing MAC protocols or requiring per-flow queueing.
