Traffic Models and Quality Evaluation Methods for Media and XR Services in 5G Systems
The present document provides traffic models and quality evaluation methods for different media and eXtended Reality (XR) Services. In order to address this, generic modelling considerations are introduced and for different services reference designs, simulation models and suitable quality metrics are reported. This information permits to obtain accurate information on exact bitrate and delay requirements in uplink and downlink, develop detailed traffic traces, develop suitable statistical models for media and XR traffic and to evaluate the expected media quality of such services. The information may be used by other 3GPP groups in order to assess media quality for different configuration of 5G System parameters, as well as for evaluating the requirements in terms of QoS for XR and media services.
