世界范围内大量未经许可的毫米波频谱的开放引发了人们对开发高比特率多媒体服务和应用的极大兴趣。毫米波通信设计面临的具体挑战包括大规模衰减、大气吸收、相位噪声、有限增益放大器等，本文旨在定义和评估表征多媒体QoS的重要指标，并在毫米波框架内共同考虑这些技术挑战。为此，我们设计了一个QoS感知的多媒体调度方案，以实现性能和复杂性之间的权衡，其中进行准确的传播分析，并指出合适的对策技术，以满足QoS要求。此外，潜在的多媒体应用进行了分析，并提供了可能的解决方案。实验结果表明，所提出的多媒体调度方案能够在实际的毫米波通信系统中有效地执行。
The worldwide opening of a massive amount of unlicensed millimeter-wave spectrum has triggered great interest in developing high-bit-rate multimedia services and applications. Specific challenges for mmWave communication design include large-scale attenuation, atmospheric absorption, phase noise, limited gain amplifiers, and so on. This article aims to define and evaluate important metrics to characterize multimedia QoS and jointly takes these technical challenges into account in the framework of mmWave. To this end, we design a QoS-aware multimedia scheduling scheme to achieve the trade-off between performance and complexity, in which accurate propagation analysis is carried out and suitable countermeasure techniques are pointed out to satisfy the QoS requirements. Moreover, potential multimedia applications are analyzed and possible solutions provided. Illustrative results indicate that the proposed multimedia scheduling scheme can perform efficiently in a practical mmWave communication system.
