Quality of service mechanism for supporting extended reality traffic

A method of wireless communication, comprising:

• receiving, by a network node, an indication that activates an extended reality traffic transmission optimization by which an efficiency of a transmission of payloads of a set of protocol data units having different importance is increased;
• detecting, by the network node, whether there is a missing network packet;
• and
• canceling, by the network node, a scheduled transmission of remaining network packets in a same data unit set as the missing network packet, upon determining that the data unit set including the missing network packet has a first importance value, or canceling, by the network node, a scheduled transmission of remaining network packets in all data unit sets in a same data unit set group as the missing network packet, upon determining that the data unit set including the missing network packet has a second importance value, wherein the second importance value has a higher importance than the first importance value.

A method of wireless communication, comprising:

• transmitting, by a wireless device, to a network device, an indication that the wireless device supports an extended reality traffic transmission optimization by which an efficiency of a transmission of payloads of a set of protocol data units having different importance is increased;
• receiving, by the wireless device, from the network device, after transmitting the indication, a notification that the extended reality traffic transmission optimization is activated for the wireless device;
• detecting, by the wireless device, whether there is a missing network packet;
• and
• canceling, by the wireless device, a scheduled transmission of remaining network packets in a same data unit set as the missing network packet, upon determining that the data unit set including the missing network packet has a first importance value, or canceling, by a network node, a scheduled transmission of remaining network packets in all data unit sets in a same data unit set group as the missing network packet, upon determining that the data unit set including the missing network packet has a second importance value, wherein the second importance value has a higher importance than the first importance value.
