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.

Dependent claims

A method for informing an access point of a wireless local area network (WLAN) that a client station has data to transmit to the access point, the method comprising:

generating, at the client station, a media access control (MAC) data unit (MPDU) that includes a MAC header, wherein the MAC header includes a control field that indicates an amount of data queued at the client station for transmission to the access point, wherein the control field includes i) a first subfield that specifies a scale factor, and ii) a second subfield that specifies a base value, and wherein multiplying the specified base value by the specified scale factor indicates the amount of data queued at the client station;
and
transmitting, by the client station, 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.

A communication device, comprising:

a network interface device associated with a client station of a wireless local area network (WLAN), wherein the network interface device includes one or more integrated circuits (ICs) configured to:
generate a media access control (MAC) data unit (MPDU) that includes a MAC header, wherein the MAC header includes a control field that indicates an amount of data queued at the client station for transmission to the access point, wherein the control field includes i) a first subfield that specifies a scale factor, and ii) a second subfield that specifies a base value, and wherein multiplying the specified base value by the specified scale factor indicates the amount of data queued at the client station, and
transmit 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.
