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.

Abstract: A wireless device, a network node, a core node and methods for handling radio communication of data between the wireless device and the network node in a wireless network. The network node transmits system information related to availability of a potential data bearer dedicated for data tolerating a certain delivery delay, which is received by the wireless device in idle or inactive mode.

Abstract: Systems and methods for reflective mapping of flows to radio bearers are provided. In some embodiments, a method of operation of a radio access node includes determining a flow-to-radio bearer mapping by determining a radio bearer to which to map a flow. The method also includes mapping the flow to the radio bearer according to the flow-to-radio bearer mapping, where the radio bearer is different than a previous radio bearer to which the flow was mapped and transmitting a downlink transmission for the flow on the radio bearer according to the flow-to-radio bearer mapping. The downlink transmission includes a flow identifier of the flow. In this way, a flow may be quickly mapped to another radio bearer for a wireless device. This may be for when the transmission of a flow starts or changes in characteristics. Also, control signaling is reduced between the radio access node and the wireless device.
