Abstract
Transmission of time information data for measuring QoE metrics. Systems, methods, and instrumentalities can be configured for transmission / reception of quality of experience (QoE) timing information for measuring QoE metrics. A device (e.g., a wireless / transmission reception unit (WTRU) and / or a media capability for augmented reality (MeCAR) device) can receive, from a split rendering server (SRS), a real-time control protocol (RTCP) message including a QoE timing information extended report (XR) block. The QoE timing information XR block can indicate a block type of QoE timing information. The QoE timing information (e.g., recorded at the SRS) can include an estimated time, a start rendering time, a split rendering server output time, and a scene update time. The device can calculate at least one QoE metric based on the QoE timing information.
