Abstract: Coordinated Orthogonal Frequency Division Multiple Access (C-OFDMA) in high density networks may be provided. A primary Access Point (AP) and a subordinate AP may be caused to use an omnidirectional antenna pattern during a synchronization period. Next, the primary AP and the subordinate AP may be caused to use an omnidirectional antenna pattern during a time in which the primary AP sends a subordinate Trigger Frame (TF) during a first C-OFDMA period. The primary AP and the subordinate AP may then be caused to use a directional antenna pattern during times in which the primary AP and the subordinate AP Uplink (UL) data during the first C-OFDMA period and Downlink (DL) data during the first C-OFDMA period.
