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.
