Measurement-based performance investigation on mobile video streaming in LTE-A cell edge areas

Abstract

With rapid growth of the number of mobile smart devices, the resource usage for video streaming, as one of the mostly popular mobile applications, also increases drastically. Thus, understanding the practical resource usage in current LTE-A systems becomes more important, which may serve for the future deployment of mobile communication systems. In this paper, we first introduce a methodology to measure the practical resource usage pattern of the mobile video streaming by taking YouTube service as a representative example. Then, we analyze the data measured from the LTE-A systems in South Korea to investigate the required data rate to support high definition (HD) video streaming and its relation to spectral efficiency, signal to interference and noise ratio (SINR), etc. In addition, we also analyze the resource assignment pattern in the time domain when streaming. © 2019 IEEE.
