Abstract: A client station generates a media access control (MAC) data unit (MPDU) that includes a MAC header. The MAC header is generated to include a control field that indicates an amount of data queued at the client station for transmission to an access point. The control field is generated to include i) a first subfield that specifies a scale factor, and ii) a second subfield that specifies a base value, and multiplying the specified base value by the specified scale factor indicates the amount of data queued at the client station. The client station transmits the MPDU to the access point to inform the access point of the amount of data queued at the client station for transmission to the access point.
