Adjusting a jitter buffer based on inter arrival jitter

A method for a wireless user equipment (UE) device to select a de-jitter delay based on inter-arrival-jitter (IAJ), the method comprising:

• by the UE:
• wirelessly receiving a plurality of packets corresponding to a first application of a first application type;
• calculating an IAJ value for each respective packet of the plurality of received packets;
• generating an IAJ distribution for the plurality of received packets using the IAJ values of the plurality of received packets;
• determining a target packet loss rate for received packets based on the first application type;
• determining a quality of service (QoS) value for use in determining a de-jitter delay value, wherein the QoS value is mapped from the target packet loss rate based on a first probability distribution;
• calculating the de-jitter delay value based on the IAJ distribution generated for the plurality of received audio packets and the QoS, value, wherein the de-jitter delay value corresponds to the target packet loss rate, and wherein said calculating the de jitter delay value comprises applying the QoS value to the IAJ distribution to determine the de-jitter delay value;
• performing playback of the plurality of packets, wherein the performing is based at least in part on the de-jitter delay value;
• and
• performing:
• receiving additional packets of the first application,
• updating the IAJ distribution based on the additional packets,
• recalculating the de jitter delay value by applying the QoS value to the updated IAJ distribution, and
• performing playback using the recalculated de-jitter delay value repeatedly throughout execution of the first application.

A non-transitory computer-readable memory medium that stores instructions that, when executed at a wireless device, cause the wireless device to:

• determine a target packet loss rate for data packets corresponding to a first application based at least in part on a first application type of the first application;
• wirelessly receive a plurality of data packets corresponding to the first application type;
• calculate an inter-arrival-jitter (IAJ) value for each of the plurality of received data packets;
• generate an IAJ distribution for the plurality of received data packets based on the calculated IAJ values;
• determine a quality of service (QoS) value for use in determining a de-jitter delay value, wherein the first value is mapped from the target packet loss rate for data packets corresponding to the first application type based on a first probability distribution;
• calculate the de-jitter delay value which meets the target packet loss rate for data packets corresponding to the first application type based on the IAJ distribution generated for the plurality of received audio packets and the QoS value, wherein said calculating the de jitter delay value comprises applying the QoS value to the IAJ distribution to determine the de-jitter delay value;
• perform presentation of the plurality of data packets using the de-jitter delay value;
• and
• perform:
• wirelessly receiving additional data packets of the first application,
• updating the IAJ distribution based on the additional data packets,
• recalculating the de-jitter delay value by applying the QoS value to the updated IAJ distribution, and
• performing presentation using the recalculated de-jitter delay value repeatedly throughout execution of the first application.
