Abstract

The recent Long-Term Evolution (LTE) standard, thanks to the provision of high data rates, will enable future immersive and interactive multimedia applications over wireless. In this paper, we study the performance of 2D and 3D video transmission over LTE networks. The LTE standard bandwidth ranges are considered in order to explore the impact of the LTE bandwidth scalability on the transmission of 2D and 3D video traffic to the end users. This dependency is investigated through the packet loss ratio (PLR) and average throughput as user-oriented metrics, and the cell spectral efficiency as a system-oriented metric. Furthermore, a PLR-based Admission Control (AC) strategy is introduced in the system for which the achieved trade-off between the system resource utilization and the quality level provided to the different users is investigated. The simulation results provide guidelines for combining bandwidth scalability and admission control strategies in LTE networks in order to achieve high system resource utilization and video quality for the LTE users.

带宽可扩展性和在LTE网络上高效的2D和3D视频传输

由于提供了高数据速率，最近的长期演进(LTE)标准将使未来的无线沉浸式交互式多媒体应用成为可能。在本文中，我们研究了在LTE网络上2D和3D视频传输的性能。考虑LTE标准带宽范围，探讨LTE带宽可扩展性对向终端用户传输2D和3D视频流量的影响。这种依赖关系通过丢包率(PLR)和平均吞吐量作为面向用户的度量，以及小区频谱效率作为面向系统的度量来研究。此外，在系统中引入了基于plr的准入控制(AC)策略，研究了系统资源利用率和提供给不同用户的质量水平之间的权衡。仿真结果为LTE网络中带宽可扩展性和准入控制策略的结合提供了指导，从而为LTE用户实现更高的系统资源利用率和视频质量。
