摘要

自2008年以来，长期演进(LTE)已经在3GPP标准化，目标是提供具有严格服务质量(QoS)要求的高数据速率业务。它是目前发展最快的移动技术，并逐渐成为蜂窝网络中使用的主流无线接入技术。最新的视频编码标准，高效视频编码(HEVC)，实现了比其前身高级视频编码(AVC)更高的压缩率，并且在相同的质量水平下使用的带宽几乎减少了50%。HEVC是一种领先的视频压缩技术，将用于向用户提供高清(HD)和超高清(UHD)视频内容。HEVC的扩展，如3D-HEVC，现在正在由MPEG开发和标准化，以提供3D视频内容。LTE当前的问题包括它对正在传输的数据包类型及其对最终用户的重要性缺乏认识。本文的目的是研究3D-HEVC在LTE网络上的性能，使用诸如丢包率和平均用户吞吐量等指标。我们还以包优先级方案的形式提出了一个跨层解决方案，以帮助为用户提供更好的体验质量(QoE)，并展示其优于不感知qos的基线方案的优势。

A packet prioritization scheme for 3D-HEVC content transmission over LTE networks

Long Term Evolution (LTE) has been standardized at the 3GPP since 2008 and targets the delivery of high data rate services with strict quality-of-service (QoS) requirements. It is now the fastest ever growing mobile technology and is gradually becoming the mainstream radio access technology used in cellular networks. The latest video coding standard, High Efficiency Video Coding (HEVC), achieves higher compression rate than its predecessor Advanced Video Coding (AVC) and for the same level of quality uses almost 50% less bandwidth. HEVC is the leading video compression technology that will be used to deliver high-definition (HD) and ultra-high-definition (UHD) video content to users. Extensions of HEVC, such as 3D-HEVC, are now being developed and standardized by MPEG to deliver 3D video content. The current issues with LTE include its lack of awareness regarding the type of packets being transmitted, and their importance to the end user. The aim of this paper is to investigate the performance of 3D-HEVC over LTE networks using metrics such as packet loss ratio and average user throughput. We also propose a cross-layer solution in the form of a packet prioritization scheme to help provide better quality-of-experience (QoE) to users and demonstrate its advantages over a baseline scheme that is not QoE-aware.
