A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications. The WDEV generate a first orthogonal frequency division multiple access (OFDMA) frame that specifies information regarding resource unit (RUs) to be used by other WDEV. The WDEV transmits the first OFDMA frame to other WDEVs and receives a second OFDMA frame from the WDEVs based on some RUs specified within the first OFDMA frame. The WDEV then generates and transmits a third OFDMA frame to the other WDEVs (e.g., based on RU(s) spanning RU(s) within which information is received in the second OFDMA frame).
