  • Patent number: 11483847
    Abstract: According to certain embodiments, a method by a first network node operating as a Radio Access Network (RAN) node for dynamic scheduling prioritization for live uplink streaming includes receiving at least one priority level. Based on the at least one priority level, an expected quality level is determined. The expected quality level is defined as a Quality of Service (QoS) of a QoS flow being scheduled with a service quality above a minimum quality level and below a maximum quality level. A current service quality for a plurality of QoS flows is determined. Based on the combined current service quality and the expected quality level, a scheduling priority for assigning resources to a plurality of QoS flows is determined.
