Abstract

Full-duplex asymmetric transmission can improve the system throughput and transmission fairness effectively. However, in the real WIFI network, the length of downlink packet is usually much longer than that of uplink, which can decrease the system performance. In this paper, a WIFI network with a full-duplex access point (FD_AP) and half-duplex stations is studied and a full-duplex Medium Access Control (MAC) protocol based on power control and rate selection (PCRS) is proposed to reduce the effect of Inter Client Interference (ICI) and improve the system throughput and transmission fairness. Furthermore, the differences in packet length and minimum sensitivity are taken into consideration. Simulation results show that PCRS MAC protocol can achieve higher throughput, as compared to the current Distributed Coordination Function (DCF) and a simple full-duplex MAC protocol without PCRS. PCRS MAC also maintains a high level of fairness.
