Stream classification service (SCS) for mobile and network centric end-to-end WLAN QoS management

A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an Access Point Station (AP), the processing circuitry configured to:

• encode a Capabilities element for transmission to a station (STA) to indicate that the AP supports a Quality-of-Service (QoS) flow;
• decode an Stream Classification Service request frame received from the STA requesting establishment of the QoS flow with the AP, the Stream Classification Service request frame including a first characteristics element that describes QoS characteristics of the QoS flow,
• wherein the first Characteristics element includes at least a Minimum Data Rate, Minimum Service Interval, a Maximum Service Interval, a Service Start Time, a Medium Time and a direction, the direction being one of downlink and uplink;
• encode an Stream Classification Service response frame for transmission to the STA,
• wherein when the request for establishment of the QoS flow is rejected by the AP, the processing circuitry is configured to encode the Stream Classification Service response frame to include a second characteristics element providing recommended characteristics for the QoS flow,
• wherein the recommended characteristics signaled by the second characteristics element include to one or more of the Minimum Service Interval, the Maximum Service Interval, the Service Start Time, and the Medium Time, and
• when the direction of the QoS flow is uplink, the processing circuitry is configured to enable transmission of uplink frames of the QoS flow from the STA to meet the minimum data rate requested in the first characteristics element.

An apparatus of a Non-Access Point Station (STA), the apparatus comprising:

• processing circuitry;
• and memory, wherein the processing circuitry is configured to:
• decode a Capabilities element received from an Access Point Station (AP) indicating that the AP supports Quality-of-Service (QoS) traffic transfer using a Stream Classification Service (SCS);
• encode an Stream Classification Service request frame for transmission to AP requesting establishment of an QoS flow with the AP, the Stream Classification Service request frame including a first characteristics element that describes QoS characteristics of the QoS flow,
• wherein the first Characteristics element includes at least a Minimum Data Rate, Minimum Service Interval, a Maximum Service Interval, a Service Start Time, a Medium Time and a direction, the direction being one of downlink and uplink;
• decode an Stream Classification Service response frame received from the AP,
• wherein when the request for establishment of the QoS flow is rejected by the AP, the Stream Classification Service response frame includes a second characteristics element providing recommended characteristics for the QoS flow,
• wherein the recommended characteristics signaled by the second characteristics element include to one or more of the Minimum Service Interval, the Maximum Service Interval, the Service Start Time, and the Medium Time, and
• when the direction of the QoS flow is uplink, transmission of uplink frames of the QoS flow from the STA to the AP is enabled by the AP to meet the minimum data rate requested in the first characteristics element.
