Recently the in-band full-duplex in wireless communication has evolved into a mature technology since the self-interference cancellation technique is able to support full-duplex capability. Moreover, some researchers focus on the full-duplex media access control (MAC) protocol design for wireless local area networks (WLANs). However, it is assumed that all the node have full-duplex capability in most study of the full-duplex MAC, and it is not practical since stations (STAs) may be half-duplex in the network while access point (AP) has full-duplex capability. In this paper, a full-duplex MAC pro-tocol named interference aware full-duplex MAC (IAFM) is proposed for the next gen-eration WLANs on the assumption only AP has full-duplex capability. In IAFM protocol, there are three mode including direct scheduling mode for normal full-duplex transmis-sion, interference collection mode for interference collection usage and none full-duplex mode for legacy transmission. Beside, direct scheduling mode and interference collec-tion mode are described in detail, and none full-duplex mode obeys the legacy MAC pro-tocol in WLANs. The power control mechanism is also discuss in this paper. The simula-tion results shows that in saturation condition IAFM protocol with power control almost double the throughput of legacy MAC protocol in WLANs.
