  Future wireless systems need to support diverse big data and Internet of
Things (IoT) applications with dramatically different quality of service (QoS)
requirements. Novel designs across the protocol stack are required to achieve
effective and efficient QoS provision. In this article, we introduce a novel
data oriented approach for the design and analysis of advanced wireless
transmission technologies. Unlike conventional channel-oriented approach, we
propose to optimally design transmission strategies for individual data
transmission sessions, considering both the QoS requirement and instantaneous
operating environment. The resulting design can effectively satisfy highly
stringent performance and efficiency requirements of future applications.
