abstract
The 360° video is gaining in popularity thanksto the increasing prevalence of virtual reality (VR)devices. This has motivated novel approaches to improve the efficiency of 360° video transmission, with techniques that range from content distribution techniques (using edge servers) tothe so-called viewport or tile prediction. In thisarticle, we take a different approach and study themaximum capacity of a 5G cell to support 360° video flows. Specifically, we provide a methodology to estimate the upper bound on the number ofsimultaneous 360° video flows that can fit in thecell. To this aim, we first define different qualityprofiles for video transmission, which are basedon subjective video quality metrics. This upperbound is calculated as a function of the qualityprofile of the video transmission. We also analyzethe impact of different parameters on the results,including scenarios with interfering cells. Ourresults quantify the ability of 5G cells to supportVR traffic and the impact of the type of video orthe quality of experience on performance.
