Cross-layer optimization for congestion control and traffic prioritization in RAN-aware XR and XR-aware ran

An apparatus implementable in an application server side network, comprising:

• a transceiver configured to communicate with one or more network nodes of the network;
• and
• a processor coupled to the transceiver and configured to perform operations comprising:
• predicting, based at least on a feedback of traffic latency, a congestion in a traffic between the application server side network and at least one user equipment (UE) of one or more UEs in a radio access network (RAN) of the application server side network based on a total RAN network load and traffics between the application server side network and the one or more UEs;
• and
• controlling, via the transceiver, the congestion responsive to an increase in a queueing delay in the traffic between the application server side network and the at least one UE and an increase in a data rate and quality of service (QOS) parameters of the traffic,
• wherein the traffic between the at least one UE and the application server side network comprises an extended reality (XR) traffic associated with an XR client-side application executed on the at least one UE.
