An access point (AP), station (STA) and method of assigning sub-carriers to full-duplex links are generally described. The STAs transmit full-duplex capability to the AP. In response, after winning channel contention, the AP determines communication information including a bandwidth, transmit power and modulation and coding scheme (MCS) for each STA. The bandwidths are independently set by the AP such that a ratio of an expected transmission time of the amount of downlink data using a unit bandwidth to bandwidth is approximately the same for each STA. The AP transmits the communication information to the STAs in a trigger frame. The AP and STAs communicate using Orthogonal Frequency Division Multiple Access (OFDMA) during a full-duplex communication session. The uplink and downlink communications terminate at substantially the same time. Acknowledgement packets are exchanged after the full-duplex communication session.
