1. An apparatus comprising logic and circuitry configured to cause a wireless communication device to:
determine a Resource Unit (RU) allocation of a plurality of RUs to a plurality of wireless communication stations (STAs), the RU allocation to allocate to a STA of the plurality of STAs an RU of the plurality of RUs, wherein an RU size of the RU allocated to the STA is based at least on a traffic rate parameter, which is dependent on a traffic rate of Downlink (DL) traffic for the STA; and
transmit a Multi-User (MU) DL Orthogonal-Frequency-Division-Multiple-Access (OFDMA) Physical-layer Protocol Data Unit (PPDU) to the plurality of STAs according to the RU allocation,
wherein the apparatus is configured to cause the wireless communication device to monitor an average traffic rate of the DL traffic for the STA, and to adjust the RU size of the RU allocated to the STA based on a comparison between a threshold and a difference between the average traffic rate and an available throughout corresponding to the RU size.
