摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of a user equipment (UE) performing a quality of experience (QoE) reporting operation for extended reality (XR) media services is disclosed. The method comprises receiving configuration information for a QoE reporting operation, determining whether an event for the QoE reporting operation is triggered based on the configuration information, generating a frame rate QoE metric comprising pose information of the UE, generating a round-trip time (RTT) QoE metric comprising a tethered delay between at least one tethered device and the UE, generating a codec QoE metric comprising 3D media codec type for 3D media, in response to the event being triggered, generating a QoE report comprising at least one of the frame rate QoE metric, the RTT QoE metric, or the codec QoE metric, and transmitting the generated QoE report.
