Method, wireless transmit/receive unit (wtru) and base station for transferring small packets

A method of transferring small packets in a wireless network, the method comprising:

• generating, by a station (STA), a control frame;
• on a condition that the STA has data available for transmission, indicating, in a duration field or via a traffic indication, an estimated time, wherein the estimated time includes at least a time required for transmission of the data;
• transmitting the control frame;
• and
• receiving a response frame associated with the control frame, wherein the response frame includes a duration field set to a value of at least the estimated time.

A station (STA) comprising:

• a processor configured to at least:
• generate a control frame;
• on a condition that the STA has data available for transmission, indicate, in a duration field or via a traffic indication, an estimated time, wherein the estimated time includes at least a time required for transmission of the data;
• a transmitter configured to at least transmit the control frame;
• and
• a receiver configured to at least receive a response frame associated with the control frame, wherein the response frame includes a response duration field set to a value of at least the estimated time.

An access point (AP) comprising:

• a processor configured to at least:
• receive, from a station (STA), a control frame, wherein the control frame comprises a duration field or a traffic indication indicating an estimated time, wherein the estimated time includes at least a time required for transmission of the data;
• in response to the received control frame from the STA, generate a response frame comprising a response duration field set to a value of at least the estimated time;
• and
• a transmitter configured to at least transmit the response frame.
