I. Introduction
Nowadays, mobile video traffic is one of the main contributors to the exponential traffic growth in cellular networks [1]. Hence, a big challenge for future networks is, first, to respectively increase the throughput, and, second, to provide efficient quality managements for this specific type of traffic. Although many solutions such as small cells, HetN ets and massive MIMO have been proposed to increase user throughput, only a few have been specifically tailored for the video delivery with high Quality of Experience (OoE).
