Abstract: A method for configuring a User Equipment (UE) to perform conditional trigger-based Radio Access Network Visible Quality of Experience (RVQoE) reporting in a wireless communications system. A network node of a Radio Access Network (RAN) can configure a UE to perform RVQoE reporting when a triggering criterion is met in a time period of observation. A UE Application layer can perform the QoE measurements and then either determine whether the triggering criterion for performing RVQoE reporting has been met based on the measurements, or the UE Application layer can pass the measurements to the UE Access Stratum layer which can determine whether the triggering criterion has been met. The UE can then provide the RVQoE report to the network node.
